SCIENCE OF ANCIENT ARCHITECTURE (Vedic Architecture)

LETS LEARN FROM OUR GLORIOUS PAST
VASTU is a science of harmonious manifestation of energy into matter or vice versa. It is a technical study of harmonious balancing of human energies with natural energies. It is set of laws oriented to align maximum benefits from a micro climatic condition and a building structure.

Vastu Science is a study of life within a defined space or the study of relationship between the occupants and building in context to land, Location and environment. All the five factors should always be in harmony.

Vastu means harmony with Nature

Occupant- To understand life of occupants in a building, it is essential to understand their psychology, behavioral patterns and generic disease pattern. The mind, body relationship needs to be clearly understood.

Building- To understand building from Vastu perspective, one must look at structure, architecture and interiors from directional perspective.

Land- Vastu emphasizes a lot on land selection. The land should have high bearing capacity and should also be fertile too.

Location- The impact of location is given prime importance in Vastu.
Environment- The impact of both internal and external environment is strongly taken into consideration while implying Vastu.

Vastu means aligning a building with the laws of nature. It is perfect harmony between nature and building with the help of its five elements. Our ancient architects knew the art and science of creating energy efficient sustainable buildings. Now days we hear of Green Building, but in India people have always been living in Green Buildings. It is because of a rat race to reduce cost, fancy looks and changed priorities that people are facing problems of sick buildings. There are four directions north, south, east, west and four corners north east, south east, south west and north west. There are two vertical directions as well. All the directions and corners have their own specific characteristics. The objective of Vastu Science is to construct buildings with spiritual connect, which further helps the occupants to connect with themselves.

Whenever we talk about VASTU, we refer to cardinal directions. But in actual sense VASTU is an energy based science. It is basically harmonization of energies in and around the building. VASTU has scientific fundamentals which are universal in nature and can be proved. VASTU emphasizes on staying in harmony with the laws of nature. The movement of Sun, Moon & Earth, effect of celestial bodies, cosmo telluric channel, geo energies, climate, wind & other natural phenomena’s affect our life drastically. The energies and vibrations around us have subtle impact on the body.

Vastu & Sun

Sun
Sun being the center of the solar system, governs multiple forces in it. It affects our life immensely. It is known that in summer sun rises from northeast east, in equinox from east and in winters from southeast east. Similarly it sets in northwest west in summer, west in equinox and southwest west in winters. That is why we see longer days than nights in summer.
The fixed time of sunrise is morning whereby the fixed place of sunrise is east. Similarly the fixed time of sunset is evening whereby the fixed place of sunset is west. At the noon time the Sun is always in South with highest heat and glare. The most interesting phenomena is to observe morning in context to east, noon in context to south and evening in context to west. The most sensitive issues of life and connect are lying in connect with nature.

When we observe sunrise we notice high level of thermal and visual comfort in northeast throughout the day. The sun moves from northeast and slowly reaches east which is the permanent place of sun rise throughout the year. It is also important to understand, what people feel, at the time of sunrise. People, who see sunrise frequently, feel active, energetic, positive and fresh throughout the day. It is also seen that people develop better concentration and connectivity levels at the time of sunrise. Now if a building has adequate opening in north east & east, the morning rays of the sun enter into the room through windows and doors and create a permanent positive environment inside. It is not just thermal comfort, visual comfort, value of light, cool air, less noise and cool albedo but infact a complete connect of self with nature. Sun also makes the northeast & east part of the building active, energetic, positive, full of concentration and connectivity. This means if the building is balanced as per the laws of nature due to adequate openings in east & north east of the building will be active, energetic & certainly positive.

Sun moves and reaches southeast; almost by noon (time varies). At this point of time sun creates an irritant and unbearable heat. But the positive part of the rays of the sun is that they are disinfectant. The sunlight has high level of heat & energy that makes it competent enough to be disinfectant.

Sun reaches southwest of the building in the early evening. West direction is the direction of setting sun which is stable, relaxing and restful. Sun does not reach North therefore they turn out to be cool zones with cool light. North direction enjoys indirect cool and diffused light of sun. It is a place for day time rooms as it is blessed with thermal and visual comfort throughout the day. Green Building Criteria’s (GRIHA- Criteria 13&14) emphasize on thermal and visual comfort in context to directions.

It is observed that even on the grounds of sun various room placements in a building can be done. The most important observation is creation of internal environment by Nature, and replicated impact on occupants. The objective of VASTU science is to give best to each functionality or use in a particular area for example concentration in study room, connectivity in prayer room, natural & disinfectant environment in kitchen, comfort and relaxed environment in bed room and contamination free environment in bathroom & toilet. This would improve the performance level of each activity and generate better level of efficiency with good results.

Solar energy is the energy, heat and light from Sun. The Earth receives 174 petawatts (PW) of incoming solar radiation (isolation) at the upper atmosphere. Approximately 30% is reflected back to space while the rest is absorbed by clouds, oceans and land masses. The spectrum of solar light at the Earth's surface is mostly spread across the visible and near-infrared ranges with a small part in the near-ultraviolet.

The total solar energy absorbed by Earth's atmosphere, oceans and land masses is approximately 3,850,000 exajoules (EJ) per year. The amount of solar energy reaching the surface of the planet is so vast that in one year it is about twice as much as will ever be obtained from all of the Earth's non-renewable resources of coal, oil, natural gas, and mined uranium combined.

Solar energy can be harnessed in different levels around the world. Depending on a geographical location the closer to the equator the more "potential" solar energy is available. VASTU emphasizes on creating solar efficient buildings which conserve energy and are green as well.

COSMIC ENERGY & VASTU

In cosmology, cosmic energy is a form of electromagnetic radiation filling the universe. With a radio telescope, there is a faint background glow, almost exactly the same in all directions, that is not associated with any star, galaxy, or other object. This glow is strongest in the microwave region of the radio spectrum, hence the name cosmic microwave background radiation. The cosmic radiations fill the whole universe with the ambient energy it has. VASTU as a science removes obstacles in the path of cosmic energy and building and fills the building with maximum cosmic radiations. Environmental Aggression may occur due to absence of adequate cosmic channel.


Geo means Earth and Pathos means suffering. Geopathic Stress means suffering from the negative vibrations of the earth which causes stress in the form of illness.Geopathic Stress is the Earth’s vibrations which rise up through the Earth and are distorted by weak electromagnetic fields created by certain mineral concentrations, fault lines and underground cavities, subterranean running water, and many more. The vibration distorted becomes abnormally high and harmful to living organisms. Geopathic Stress is the term used for natural or man-made energies emanating from the earth and which are detrimental to human health. Geopathology refers to influences originating from the soil that cause illness.

Other than the influences of the sun and other planets, the earth's GMF can also be affected by ground water movement. Faults in the earth's crust can increase neutron radiation from the core of the earth. These neutrons may be slowed down by the presence of underground water and become low-energy, thermal neutrons which can cause cell degeneration in organisms. The friction produced by the flow of water in underground channels formed by sand and gravel beds can also induce electromagnetic fields. Zones that are capable of causing ill. Students can refer to the researches submitted to the university on Geopathic Stress.

Geomagnetic field disturbances have been linked to cardiovascular diseases, and to changes in the central nervous system. The morphology and functioning of internal organs and the physiological and biochemical processes of animals get affected. They can affect blood clotting times and exacerbate the effects of other illnesses. By exposing us to changes in the GMF, building over, or close to, geomagnetic anomalies like geological faulting can affect our health.

This applies even when the anomalies are deep below the surface of the earth. The deterioration in health associated with living in such a zone has been termed ‘Geopathogenic stress’ ( or ‘geopathic stress’). Our ancient architects have again been wiser in selecting suitable land for the occupants. In case of stressed land natural herbal remedies were used for the land. Such remedies are also stated in Vedic Books of Architecture.

VASTU is a science discovered by our great saints and sages to make human beings more happy and prosperous in their homes, shops, factories and buildings.

EARTH, WATER, FIRE, AIR & SKY ARE FIVE ELEMENTS
Whole world including the human body comprises of five essential elements, i.e., earth, water, fire, air and sky. The principles of ‘’VASTU’’ are mainly dependent on the arrangement and balancing of these five elements in their proper order and proportions so that the humans can have better living conditions in a place in which they live or work.

The principles of “VASTU” also keep in view the cosmic influence of the Sun, its light and heat, the direction of the wind, the magnetic influence of the earth and influence of cosmos and various other heavenly bodies on our planet earth. As per Vastu Science balance of five elements is essential in a building and a body too. If there is a imbalance of five elements within or around the building, it can lead to ill health for the occupants.

  • WATER-NE
  • FIRE-SE
  • EARTH- SW
  • AIR- NW
  • SPACE- CENTER

FIRE

Fire, the sun and solar energy
The sun's energy drives the photosynthesis of plants. The sun also enables our bodies to synthesis vitamin D by acting on the oils of our skin. Without vitamin D our body cannot assimilate calcium, phosphorus and other minerals, resulting in rickets, tooth decay, osteoporosis and retarded growth in children as well as muscular weakness and premature aging. The sun also contributes to some of the stellar cosmic radiation which arrives on earth. Most of the energy supplied to modern industry and our homes is derived from oil, petroleum, coal and natural gas, which are finite resources. Fire plays an important role in our lives. The fire element is placed in the southeast of the plot or building.

EARTH

Soil is a very precious resource, which is being wasted all over the world. It originates from the rock that makes up the earth's crust, a mixture of granite, sedimentary and metamorphic rock, over a period of 200 to 1200 years.

How soil and rock affect our health ?

Soil and ground water, through natural processes, sometimes generate radio active pollutants, which can affect health. Uranium, occurring naturally in soil and rock, breaks down over millions of years to reach a stable state as lead. About halfway along uranium’s decay chain, an element known as radon 222 forms.

Soil deficiencies

Many soils in the world are deficient in phosphorus, nitrogen and the trace elements copper and zinc. Most deficiencies are counteracted artificially with fertilizers but some experts suspect that something is lacking in the quality of vegetation produced on chemically fertilized soils.

Soil Abuse

The most serious problem of all is that of soil that has been rendered totally useless by the dumping of toxic chemicals or their leaching on to the ground water. Other forms of soil abuse arise from leaking storage tanks or pipelines and old stock-drenching sites.


Soil Ph

The degree of acidity and alkalinity in soils (as well as their mineral element content) has a marked effect on plant growth, and hence on the availability of those nutrients upon which our health depends. The earth element is placed in the southwest of the plot or building.

AIR

Every organism needs air to survive, plants and animals are now inducing human mutually dependent upon each other for their survival; animals need the respired oxygen from plants, and plants need the carbon dioxide that animals respire. All living organism are in balance with the oceans and atmosphere and Gaia maintains this equilibrium with astounding accuracy.

Air Pollution

The air pollution is positively affecting every living organism.

Natural Air Pollution

Nature pollutes the air in many ways without our help. Sulphur oxides and particulates from forest fires and volcanoes, dust from wind storms, the hydrocarbons and pollens of plants that live on the methane and the hydrogen sulphide given off by decaying vegetation, viruses and dust from soil, the salt particulate carbon monoxide, carbon dioxide and oxides of nitrogen all result in various degrees of air pollution.

Human Air Pollution

The atmosphere is a gift from nature, which costs us nothing and requires only care for its quality. Humanity generates pollutants in such concentrations that this ultimate environmental amenity may become the ultimate environmental obscenity.
The major primary human air pollutants are carbon monoxide, sulphur oxides, oxides of nitrogen, lead, hydrocarbons, photochemical oxidants particulate and radiation.

Indoor Air Pollution

In the United States, the Environmental Protection Agency has identified 1000 pollutants that occur indoors, 60 of which can cause cancer. The building of healthy houses, free from indoor Pollution and causing as little damage to the atmosphere as possible, is paramount to maintaining the health of occupants and the balance of life on this planet. The air element is placed in the northwest of the plot or building.

WATER

Every drop of water has been here since the beginning of the earth. Water circulates in complex pathways and therefore needs to be conserved and its purity protected. Some 97 percent of all water is sea water which covers three- quarters of the Earth's surface. Of the remaining 3 percent, 2.94 percent is captured in the ice caps and at inaccessible depths in the earth. This leaves only 0.06 percent of all the water in the world as usable fresh water.

Contaminated Water

Throughout the world water is being contaminated in a variety of ways, diminishing the amount of fresh, healthy water available.

Disease

Water, the ultimate sustaining element of life, kills some 25 million people in developing nations each year. Sixty percent of these are children. Their scarce water supplies are used over and over, becoming a breeding ground for pathogens and disease carriers, resulting in outbreaks of diarrheas infections, dysentery, salmonella, typhoid and cholera. The situation is made worse by the dumping of waste products in rivers and oceans.

SPACE

Space is the sea of radiation and energy which creates the necessary conditions for the life, health and demise of all organisms. It could be said to embrace the geoenergetic, electromagnetic, electrostatic and gravitational forces exerted upon us by the Earth, the sun and other planets. It is the universal substance, the vital essence known as akasha in the Hindu Vedas. The space element is placed in the centre of the plot or building.

The Sun
It is believed that the Sun was formed about five billion years ago from a rotating mass of gas and dust. Due to compressed it gradually warmed up to temperatures of 15 million degrees. At this point nuclear fusion began in its core, and energy in the form of heat and light traveled out from the centre.

The sun is composed of 74 percent hydrogen, 25 percent helium, and 1 percent other elements, more than sixty of which are naturally occurring elements of Earth. The Sun is about 150 million kilometers from the Earth. Its diameter is around 1.4 million kilometers. The temperature at the core of the Sun is approximately 15 million degrees Celsius. The coolest part of the Sun is nearly 6,000 degrees Celsius.

The Sun has a strong magnetic field like a bar magnet in some aspects. But this magnetic field is irregular due to the movement of gases whose atoms are ionized. Particles trapped in a magnetic field usually follow the magnetic lines of force but the motion of large quantities of plasma tends to change the direction of these lines. It is this change in the pattern that gives rise to the Sun’s activities.

Sun gives us heat, light and energy
Light from the Sun is the natural source of light that heats the Earth and makes life on Earth possible. Humans, animals & Plants all need sunlight to grow. Our life completely depends on the Sun or else there is a lifeless life without sun.

Sunlight is made of tiny units of radiant energy called photons. The Photons are born in the center of the Sun’s core. Each photon carries a speck of energy and trillions of photons hit each square meter of Earth every second. A group of photons are called sunlight. Clouds, water and ground, all reflect sunlight in the space and makes earth visible from a spaceship. The amount of energy that is carried by the wave of light or a photon largely determines the colour of the light.

Light is an electromagnetic wave as it consists of both electric as well as magnetic fields. The electromagnetic radiations from sun exist in different wavelengths. The red wavelengths of the light are called long waves while violet wavelengths are called short waves. All the other colours lie between these long and short waves. Colours in the nature exist or are seen because of sunlight. Therefore the total world of beauty and aesthetics exist because of sunlight.

Energy from the Sun sets the Earth's weather in mo­tion. Heat from the Sun causes water on the Earth's surface to evaporate and form clouds that eventually provide fresh rainwater. Winds occur because the Sun's rays are more direct and thus stronger at the equator than they are at poles. The strong rays in tropical regions warm the air there, caus­ing it to rise. Cool air from the polar regions then flows under the warm tropical air. These movements create air currents that circulate around the Earth. These are influ­enced by the Earth's rotation, the surface features of the continents and variations in the amount of moisture in the atmosphere.

SUNLIGHT & HEALTH

Sunlight has a deep relationship with health. It was known in the past too, that sunlight striking the skin initiated a series of reaction in the body leading to the production of Vitamin D, a necessary ingredient for the absorption of calcium and other minerals from the diet. If Vitamin D is absent, the body will not absorb the amount of calcium required for normal growth and development of bones.

The cosmic cycles affect our universe, which then affects the Solar System, which then affects the Earth and so on down through Earth’s Climate, season’s inhabitants, right down to the smallest particle within an atom. Since all things are integrally connected in this way, everything affects everything else. Nothing escapes this process.
SUN LIGHT - SUSTAINER OF HEALTHY LIFE

ENERGY FROM SUNLIGHT

  1. The Sun is the abundant rechargeable energy to make life comfortable and to prosper on this planet EARTH.
  2. Energy from the nature is the base of Vastu Science. The whole universe is a dynamic Web of inspire able energy pattern, the solar energy and the earth energy. Duration of time study for exhausting of Earth energy resources.
  3. Human beings get maximum energy from sun which is rhythm of daily life in form of warmth and light for all actions / reactions for all the life form of Universe. A Vastu Consultant and Architect have to learn to handle the delicate balance and sensitivities of natural energy, especially the Sun in design process so as to produce an environment full of energy.

Life on Earth is under the constant influence of natural Sunlight. World have always recognized connection with sun light. It was profoundly recognized by the ancient cultures that they revered the sun as God for its blessing. Since sunlight containing Ultra Violet Rays ( Invisible form of light) is beneficial to humans , and there are certain adverse effects too. Let us not say that the God may have made mistake in giving harmful Ultra Violet light & Rays

In the Vedic period, people built homes, temples, and hermitages, applying Vastu principle, by balancing the five elements with a view to have a peaceful living, offering prayers and to live in common harmony. But in the modern world people built concrete clusters, mainly for a high rate of return. After the second world war, the architectural practice has turned into a race towards the so-called Modernization. Adopting bureaucratic values, that have resulted in worldwide pollution, environmental and ecological problems; with no peace of mind whatsoever, under any kind of shelter.

Today, the world finds itself in the grip of an energy crisis more particular in 21st century. Known sources of conventional energy are dwindling very fast. The demand for energy especially in the third world is growing. And their efforts for development are constantly being threatened by environmental issues. The developed nations, who are the largest consumers and producers of energy, find themselves threatened by the potential energy, find themselves threatened by the potential energy crunch.

This has aroused an interest in the development of energy resources as well as conservation of the available sources. And a lot of research and thinking is being generated in this new field. Solar energy, bio-technology and superconductivity have the highest priorities in research fields. We, in India , have very low energy consumption levels as compared to the level of the consumption in developed countries. However much we may wise to increase the production of conventional energy, our efforts are going to face resistance. Narmada project is a very good example of this. Hence before achieving any increase in the consumption of energy, we have to start thinking of conserving the same.

This situation forces upon us the issues of conservation of energy techniques. We can learn from the developed nation’s efforts in this sphere. It gives us a chance to reallocate our resources in better ways even before the energy situation becomes acute. Building construction, building design and architecture are such fields where the studies and research in energy conservation and renewable energy can be applied innovatively and creatively. Passive solar energy system collect transport heat by natural means. Passive system are simple in concept and use. The most striking difference between passive and active system is that the former operates on the energy available in its immediate environment and the latter imports energy to make the system work.

 

The energy requirement of a building depends upon various factors like comfort requirements location of building, usage of building etc.




CLIMATOLOGY & ITS EFFECT ON MEN – BUILDING & BUILDING MATERIAL

Man’s energy and health depend in large measures on the direct effects of his environment. It is well known that in certain climatic areas, where excessive heat or cold prevails, energy is eliminated by the biological strain of adaptation to the extreme conditions. Physical and psychological strains result from this struggle for biological equilibrium. The design, which in a given environment setting reduces undesirable stress, and at the same time utilizes all natural resources favorable to human living comfort would be considered responsive to climate.

In Vedic Period, Vastu Shastra suggested that the environment to be made livable by careful selection and orientation of building, including placement of opening, thermal efficiency of building materials, layout and space planning according to the solar and wind conditions, shading devices, vegetation and waterbodies. The Vastu consultant, therefore, had to remain alert to micro climatic conditions and regional variations. There are such examples of vernacular architectural in various climatic zones of India. Building industry consumes vast resources of energy through all phases of development, starting from the production of building materials, to its use and maintenance. Besides the scarcity, and their rising cost, their negative environmental impacts has shifted the emphasis from energy utilization to energy conservation. The need today in 21st century is to draw from the experiences of the past and blend it with the modern concepts and realities, in creating buildings, which are harmonious with the natural environment. The desirable procedure, to work towards such requirements would be to work with and not against the forces of nature.


CLIMATICAL PARAMETERS

CLIMATE

Average weather over a period of many years.

WEATHER

Integration variables atmosphere for a Period of time.

MICRO WEATHER

Integration variables Atmosphere for a brief particular place for a brief period of time.

These parameters are:

  1. Solar Radiation
  2. Air Humidity
  3. Air temperature
  4. Wind speed and direction
  5. Wind pressure
  6. Precipitation

Climate of a region affects living beings directly and indirectly. Changes in temperature are directly felt and human adapts himself by wearing clothes appropriate to the season. Woolen clothes worn in winter protect us from cold. Cotton clothes are preferred in the hot summer as they absorb sweat and allow air circulation. People living in colder regions use tight fitting clothes, while those living in tropical regions wear loose garments, which permit movement of air so that the body is kept cool. Exposure to extremes of temperature during heat waves or cold waves may cause death. Climatic changes resulting in droughts and floods affect man directly. Climatic conditions may have a direct affect on the physical & mental condition of a occupant. For example too much of cold winds from north direction in hilly areas can be extremely bad for the health of occupants. It is essential to create comfortable conditions inside, merge with the climatic conditions existing and leave the extreme conditions outside the building.

Houses built by humans are also adapted to the climatic conditions. In India, for example, in regions of heavy rainfall like Kerala, & the North East state of Assam, houses have steeply sloping roofs to drain off the rainwater. Flat roofs are commonly found in desserts. In cooler regions, houses have glass panels for doors and windows to allow more sunlight and heat. In warmer regions, houses have broad verandahs to protect them from direct sunlight. Windows are large to allow greater circulation of air so that the inside of the house remains cooler than the outside. In mountain regions like the Himalayas, South-facing slopes are preferred for construction of houses as they are exposed to sunlight. Humans are now using mechanical devices like fans, air-conditioners, heaters, humidifiers etc, to overcome adverse climatic conditions and to live in comfort. Such devices however consume large quantities of energy.

Study of Local environment

The local environment around a place may be studied by making field trips. Observations may be made about the landforms, rivers, source of water supply, drainage, land-use, crops cultivated etc, covering both natural environment and cultural aspects. Examples of environmental pollution may also be noted.

Weather: Weather is our most common topic of conversation. Hardly a day passes without weather-phenomenon claiming headlines in newspapers of news broadcasts. These may include reports of heavy floods causing breach and damage, with considerable loss of life and prosperity, in squalls or hail storms or lighting strikes.

Meteorology: It is the branch of science, which deals with the earth’s atmosphere and the physical processes in it. It includes the study of the changing atmospheric conditions- such as rain, wind thunder storm, snow, fog, which go to make up our weather. Meteorology is comparatively a young science. Meteorologist attempt to forecast future weather over a place or region on the basis of a large number of actual weather observations recorded at fixed time at meteorological observations.

Value of Weather Knowledge:

Weather plays an important part in all aspects of human life, be it personal, social or economic. It is thus an inescapable phenomenon in human life. Weather plays vital and intimate role in architecture. It is the only knowledge of the weather elements that can enable Vastu advisor to design with maximum efficiency and comfort.

Atmosphere: The atmosphere is the shallow skin or envelope of gases surrounding the surface of the earth. If the earth is compared to a baseball, the atmosphere’s thickness of the gaseous envelope or skin is still a matter of argument. What is known is that there is no sharp limit to it, and is, somewhere between 200 and 600 miles up.

Composition of Air: Although extremely light, air has weight and is highly elastic and compressible. It is a mixture of gases, of many gases entering into its composition, chief are Nitrogen (comprising 78% of the volume of the dry air) and Oxygen (comprising 21%), Argon, Carbondioxide, Hydrogen, neon, Helium, Krypton and Xenon are also present in very small quantities. Besides these fixed components, the atmosphere also contains water vapor in variable amounts.

Air envelopes the entire surface of earth on which we live. Although it is not visible to us we can always feel it. When we run fast, it opposes our motion and when it is in fast motion, it can uproot even big trees. The fast moving air is called storm. Air is absolutely essential for life. No living and being plant or animal can survive without it. It gives us energy and plants get their food from the carbon dioxide present in it. Water vapor in the air helps to produce rains. The quantity of water vapor in the air varies from place to place. The desert air is dry whereas the air in the areas adjoining the sea contains considerable amount of water vapor. This is why it rains heavily in places near the sea.

Presence of Water Vapour : Although an invisible gas, water vapor is a very important constituent of the atmosphere , under certain conditions water vapor can condense into the millions of tiny droplets of water or crystals of ice which constitutes fog near the frond and clouds. Clouds produce rain, snow or thunderstorm and also prevent partially, radiation of heat from the earth. It is therefore necessary to know something about the water vapor in the atmosphere, which produces weather.

Humidity and Saturation: The amount of water vapor in the air is called humidity. There is a limit to water vapor content of the air at any temperature. Air at a given temperature in contact with a flat surface of pure water (or ice) can take only a limited amount of water vapor. The higher the temperature, the more water vapor it can contain. Air is said to be saturated at a particular temperature when it contains the maximum possible quantity of water vapor.

Relative humidity: Relative humidity is a term used to express the degree of saturation of air. It is the percentage ratio of the amount of water vapor actually present in the air to the amount, which would be needed to saturate it at that temperature. When air can hold more water than it is cold. When the air with a given amount water vapor is warmed, its relative humidity decreases. If it is cooled, the relative humidity goes up. Normally the relative humidity of the air is highest at the time of the sunrise when the surface temperature is minimum and decreases as the temperature goes up.

Now the question comes, what is the source of moisture in the air? Moisture is always present in the air in the form of water vapor, but we are unable to see it. The amount of water vapor present in the air varies from place to place. Even the air in the big deserts contains some amount of water vapor. As we know, about 70% of the earth’s surface is covered with water. Due to the solar heating water from the seas, rivers, lakes and ponds evaporate and mix with air. And thus the constant supply of water vapor to the air is maintained. In the scientific language the water vapor present in the air is called humidity. It varies from season to season. The amount of humidity is more during the summers than in winters. This is because large quantities of water from the seas, rivers, ponds etc gets converted into water vapor due to the higher atmospheric temperature during the summer. Also, the air expanded due to heating is capable of accommodating more water vapors. When it rains, the humidity increases tremendously, because a very large portion of the earth’s surface is covered with water, which goes on evaporating into atmosphere.

It is the water vapor present in the air that causes the formation of the dew, fog, frost, snow etc. We get a lot of information about the weather by studying the variations in the humidity. The instrument, which measures humidity, is called ‘Hygrometer’. High humidity indicates the possibility of rains. Cotton mills require humid atmosphere because the presence of moisture in the atmosphere prevents the breaking of cotton threads. Thus, we see that the study of humidity helps us in many ways.

The Effects of Climate on Man: Man’s energy and health depend in large measure on the direct effects of his environment. It is a common experience to find that on some days the atmospheric conditions stimulate and invigorate our activities, while at other times they depress the physical and mental efforts. It is also well known that in certain climatic areas, where excessive heat or cold prevails, energy is diminished by the biological strain of adaptation to the extreme conditions.

The measurement of climatic effects has been investigated in many ways, here two methods of evaluation may be mentioned. One method describes the negative effects of climate on man, expressed as stress, pain, disease and death. The second defines the conditions in which man’s productivity, health, mental and physical energy are at their highest efficiency. Both approaches may be combined, to show coinciding and complementary relationships, in defining desirable or disagreeable atmospheric and thermal conditions.

Effect of Weather on Human Body: Our daily life cycle comprises states of activity, fatigue and recovery. It is essential that the mind and body recover through recreation rest and sleep to counter balance. The mental and physical fatigue resulting from activities of the day. Unfavorable climatic conditions and the resulting stress on body often hinder this cycle and mind causes discomfort, loss of efficiency and may eventually lead to a breakdown of health. The effect of weather on living beings is therefore a factor of considerable importance. It is the task of the designer, architect or vastu expert to strive towards the optimum of total comfort. He has to consider both the physical as well as the emotional aspects of our environment.

Human thermal control is the dominant problem in tropical climates. Human response to the thermal environment does not only depend upon air temperature but also humidity, radiation and air movement. To understand the effect of these climatic factors, it is necessary to examine briefly the basic thermal processes of the human body i.e. heat gain and heat loss.

The body continuously produces heat. Most of the bio chemical processes involved in tissue building, energy conversion and muscular work are exothermic i.e. heat producing. All energy and material requirements of the body are supplied from the consumption and digestion of food. Of all the energy produced in the body, only about 20% are used while remaining 80% is ‘surplus’ heat and must be dissipated to the environment e.g. solar radiation or warm air that also has to be dissipated. The body can release heat to its environment by convection, radiation and evaporation and to some extent by conduction. Conduction depends on the temperature difference between the body surface and object the body is in direct contact with.

The physical environment consists of many elements in a complex relationship. One can try to describe the environmental constituents as: light, sound, and climate, space, and animate. They all act directly upon the human body, which can either absorb them or try to counteract their effects. Physical and psychological reactions result from this struggle for biological equilibrium. Man strives for the point at which minimum expenditure of energy is needed to adjust himself to his environment. Conditions under which he succeeds in doing so can be defined as the “comfort zone”, wherein most of his energy is freed for productivity.

The shelter is the main instrument for fulfilling the requirements of comfort. It modifies the natural environment to approach optimum conditions of livability. It should filter, absorb, or repel environmental elements according to their beneficial or adverse contributions to man’s comfort. Ideally, the satisfaction of all psychological needs would constitute the criterion of an environmentally balanced shelter. Here, however, only one element will be analyzed – the feeling of thermal balance. Without it, any definition of comfort is impossible.

The major elements of climatic environment, which effect human comfort, can be categorized as: air temperature, radiation, air movement and humidity. There are others too, such as chemical differences, physical impurities electric content in the air. They act on man in a complex relationship, means by which the body exchanges heat with its surroundings can be classified into four main processes: radiation, conduction, convection and evaporation. It is estimated that radiation accounts for about 2/5 of the heat loss of the body, convection for 2/5 and evaporation 1/5; however, these proportions change with variations in the thermal conditions. The actual relative magnitude of body heat production and heat interchange with the environment may vary within wide limits. The vital processes of the body are accompanied by considerable energy exchange. This energy is derived from the oxidation of foodstuffs and is utilized with a gross efficiency of the order of 20%; the remaining 80% of the energy are expanded as heat. Even when the body is completely at rest and in warm surroundings its heat production does not fall below a certain minimum level – the basal metabolism.

The Vastu Experts’s problem is to produce an environment, which will not place undue stress upon the body’s heat – compensation mechanism. The approach should be rephrased in terms of comfort; the presentation should be ingraphic form; and, to be easily applicable, the data should derive from the empirical findings available to the practicing architect. Desirable air movements should be utilized for cooling in hot periods, and as a relief from vapor pressure during times of high absolute humidity. Conversely, air movement should be blocked and avoided by a bioclimatic analysis for the region, which divides the year into overheated and under heated during the cold season. The yardstick for evaluating wind movements is provided by a bioclimatic analysis for the region, which divides the year into overheated and under heated. Before investigating possible arrangements that will give wind protection or will utilize air movements beneficially, it is necessary to consider the orientation of the building.

All external heat impacts must pass through the building shell material; the process is comparable to the absorption of moisture by a porous material. Successive layers of the structure become ‘saturated’ with heat until finally the effect is felt on the inside surface. Anyone who has entered a large stone church on a hot summer day may have experienced it’s comforting coolness. In such structures the large mass of the masonry materials absorbs and reflects the coolness of the previous night, resulting in a delayed temperature approximating a seasonal average. A similar effect is evident in such ‘crypto-climatic’ examples as the pyramids, where the interior space is negligible in relation to the immense mass of heavy material. The interior tomb chamber will constantly be close to the yearly average outdoor temperature. Historic houses sturdily built of heavy wall materials for reasons other than the thermal stability nevertheless react well from that standpoint. By comparison, the structures of today are extremely light and thin and the question of temperature balance arises urgently. Under many conditions light structures are quiet undesirable, being at the mercy of external forces just as light boats are tossed about on a high sea. The aim of this inquiry is to define the material requirements for an opaque shell, which, by damping and distribution, will balance the external thermal impacts of various regions and exposures. These qualities may be determined by investigating the processes and properties that allow for surface control, touching briefly the related problems of moisture and deterioration.

Ventilation: Ventilation consists an inlet of fresh air and maintaining a movement of air in the rooms and the building. For proper ventilation, windows should have minimum area of 1/8th of the floor area of the room and the aggregate area of the doors and windows should not be less than 1/4th of the floor area of the room. Windows should be provided 2’-6” above floor level. In addition to the doors and windows, ventilators should be provided having a total area of 4% of floor area. Ventilation serve as good exit for inside air and should be provided as near to the ceiling as possible within 60cm (2 feet) from the ceiling. The area of each ventilator should not be less than .3 sq. m (3 sq. ft.)
In living room, at least two windows should be provided one in each of the opposite walls, if that is not possible, there should be a at least two window one in each of the adjoining walls. Bath rooms, toilets, kitchens should have at least one window of adequate size.

Vastu is a nurture-oriented science. It all begins with considering your home as a living organism. From a Building Biology perspective your home is your “third skin,” your outermost layer. Your physical skin is the first layer and your clothes are the second layer or second skin. As you start thinking of your home this way, and how it interacts with you and your family, you realize it’s all interconnected. Everything from the materials used to build your home, to the furnishing inside, to how your care for it, need to be considered in an overall plan for health.

When everything works together to support everything else in this way an optimally healthy environment is achieved. In order for a home to be healthy it needs to be able to facilitate a balanced exchange of air and humidity, just like our physical lungs do. This process is a form of breathing. A breathing home needs to be able to allow humidity and air to move in and out of its walls. Homes need to be able to keep warm or stay cool, just like we do.

It is essential that only healthy building materials should be used to enable homeostatic abilities in building. Building Physiology will only be active if is constructed with lot of wisdom and care. The use of toxic substances in construction is standard. The average person (builder or homeowner) lacks a background in chemistry and operates under the false assumption that in order for building products to be allowed on the market, they must be reasonably safe. This form of faulty workmanship falls under the category of ignorance.

Turning your home into a health heaven is a process, just like raising a child or caring for a family member. It takes time and effort but you will know you did your best.

(Science of impact of Vastu on Human Behaviour,and diseases in context to internal & external environment)


Vaastu is a science of creation with the laws of nature. Vastu creates a perfect harmony between nature, building and the occupants with help of five elements. It helps in creating a building embodied with energies considering the forces of nature like solar energy, gravitational pull, telluric energy, magnetic field, winds & humidity etc. The forces of nature create automatic machinery within the building, the moment a three dimensional mass of energy like a body or a building comes in contact with the forces of nature.. The automatic systems so created for healthy sustenance in the building are self created and self maintained. It is like automatic systems of body like excretion system, respiratory system and blood circulation system. This term is scientifically called Building Physiology.

Due to the different forces of nature there are different environments created in different parts of the building. Different environments have their own psychological impact on the occupants. The occupants in the building also perceive such environments differently due to different sensitivities, immune system levels, different human behaviors, emotions, brain functioning and diseases. This is like husband and wife living in one room may have different experiences, perceptions and feel in the same direction. This is because the people perceiving the environment are may be different. The study of Psychological impact of environment on the occupants is called Building Psychology.


It is observed in building psychology that every direction does not have same impact on all the occupants. Different people perceive different directions differently. Their comfort level, relaxation, enjoyment is a personal need depending on various considerations. Therefore every individual needs customized study of behavior to understand which direction will suit better. In fact all the directions and corners have their own specific characteristics and psychological impact.

The sun and other forces of nature automatically creates different internal environmental envelopes in the building and its combined effects are called directions. The objective of Vaastu science is to give best, to each functionality in a particular area for example concentration in study room, connectivity in prayer room, natural & disinfectant environment in kitchen, comfort and relaxed environment in bed room and contamination free environment in bathroom & toilet. This would improve the performance level of each activity and generate better level of efficiency with good results. Human psychology goes hand in hand for example if a person lacks the power of concentration, it is essential for that person to create a prayer room in north east of the building & face the rising sun at the time of praying. Similarly a child who has poor learning ability must ensure that the study room is in east of building and the child faces east while studying. This would improve the grasping powers and retention abilities of the child.

After long researches in hospitals, Vaastu is found to have close relationship with anatomical problems of occupants as well. The effects of the direction may differ from person to person. It is a fact that one single direction may have different psychological effects on different people. Human psychology changes with age and time.

This science of matter & energy, time & space in context to human mind, body and internal environment has been researched by Dr.R.M.Mehra PhD & DSc. Through his research a new subject has evolved with the name “vasteriology ™  ” which means the science of Vastu, Interiors & Psychology. Under the science of vasteriology ™   a building is diagnosed with help of scientific instruments, occupants are analysed through psycho analysis, environment is dignosed through non physical tools of vasteriology ™   and customized solutions of vasteriology ™   are given.

vasteriology ™   is a complete science in itself which highlights various psychological and anatomical problems in context to Vastu. It uses the science of transformation to create better environments as per the theories of different psychologists. vasteriology ™   is the modernistic & scientific in its approach. vasteriology ™   can be termed as specialized branch of Vaastu science, monitoring on the most important aspect of the home that is internal environment created through interiors. It is found that people spend 75% to 90% of their time indoors. Therefore the control and impact of internal environment is much higher than external environment.

It is meant for exceptionally logical people with flair of logic, design and sensing powers. It works on the concept of creating holistic & healthy environment. It is a realistic subject which ensures realistic remedies. The remedies are universal, uniform and does not restrict on grounds of culture, caste, region or religion. vasteriology ™   also takes the privilege of proving the scientific part of Vaastu and making it an established science.
