vastu and shastra

1. Contribution of vastu Shastra on green building concept Debdatta Chakraborty Civil Engineering ( B.Tech )

2. Why vastu concept? Is it applicable? 2 The Sanskrit word ‘ Vastu ’ comes from the underlying root of Vas which means “to dwell, live, stay, abide”. The construction of a house in ancient India was not only a housecraft but also a sacred ceremony and the house was considered a living organism.

4. Elements of vastu 4 Earth (Magnetic Field) Water (Gravitation) Fire (Solar Energy) Air (Wind Energy) Space (Cosmic Energy)

5. panchtattva The entire Universe, whether it is the stars, the plants or any form of life, is made up of these five elements only. Even buildings are a manifestation of these five elements, through their proportion may vary from one building to another. Each direction is dominated by one element, which create and control the life of a building’s inhabitants. The balance state cause positive and the imbalanced state cause negative effects on one’s life. 5

6. Green building concept 6 According to World Green Building council- A ‘green’ building is a building that, in its design, construction or operation, reduces or eliminates negative impacts, and can create positive impacts, on our climate and natural environment. Green buildings preserve precious natural resources and improve our quality of life.

9. VAASTU V/S green building VASTU IGBC CODE ELEMENT - EARTH   Vastu is all about considering the nature. Vastu described that deodar, chandan , sheesam , shaal are suitable for all kind of people. However, always avoid the trees with milky liquid contract or trees with thrones inside a plot. Fruit bearing trees are good for any vastu . Some trees should be in NE direction, it helps to absorb UV Rays. [1] We can testify the quality of soil before choosing a land by ancient vastu technology. The soil moisture, density and its quality. Earth is another important element of vastu .on the selected land dig a pit measuring one arm in length, width and depth, fill up the pit with the same sand/soil excavated from it. If any sand is left over after the pit is fully refilled, the plot is excellent. If exactly filled then the land is mediocre. In addition, if extracted sand is insufficient then the land is inferior and there is heavy chance of soil erosion in future. Black and clayey soil is not good while designing the foundation. Always avoid Site with big boulders, anthills or burial and those with loose or filled-up earth. [1] Any land, which make one feels happy and joyful, a person, feels peaceful and serene such a land is normally favourable. As far as possible, the site should be level or sloping towards North and East or Northeast. If it is a small one, which normally is the case in the towns or cities, there should not be any big trees like Aswatha ( peepul ), Mango because its roots and branches could harm the building. [2] The square plot is best. [2] At the scission of river, having big boulders, at the foothills, in a pit these should be left alone. A rectangle stretches the energy lines and the plot grows weaker as the length to breadth ratio increases. If the land is tilted towards the east, it brings money and riches, if the land is tilted towards southwest is results grief and so on. [2] Use of natural stone and mud brick. But if there is any big boulders or a deep hole previously exists in site, that should be avoided. For all types of house use one type of wood or two types of wood. It is said that using a single type of wood eliminates all grief. Wood can be used for piling and small foundation work. [1] Site, which has fertile earth, flowering plant, are preferable. Natural vegetation, green grass ( durva , kush , kash grass) are preferable if already exists. Nevertheless, any dense bush or cactus type bush or plant. To check Jivantta (life) of a land, the earth is fertile or not take some mustard or barley seeds, put them in ground. After watering, if the seeds germinate within 3 nights then the land is superior for living, if not should be avoided. [1]   Site Preservation: SA Credit 2 - Encourage retaining the site features to minimise site damage and associated negative environmental impacts. Existing Trees, Natural rocks, site contour Points 2 Soil Erosion Control: SSP Mandatory Requirement 2 - Control soil erosion and sedimentation, thereby, reducing negative impacts to the site and surroundings.   Natural Topography or Vegetation: SSP credit 4 - Avoid disturbance to the site by retaining natural topography (and/ or) design vegetated spaces on the ground, for at least 15% of the site area. Points 2   Preservation or Transplantation of Trees: SSP credit 5- Preserve existing fully-grown trees and plant new tree saplings, to promote habitat and biodiversity. Case A: Preservation or Transplantation of Existing Trees Case B: Plantation of Tree Saplings Points 1 Sustainable Building Materials: BMR Credit 1 - Encourage the use of building materials to reduce dependence on materials that have associated negative environmental impacts.   Compliance Options:- 1.4 Local Materials: Points 2 1.5 Wood Based Materials: Points 2

10. VAASTU V/S green building VASTU IGBC CODE ELEMENT - WATER   NE direction is also suitable for underground water tanks. Due to water cosmic rays filtered down to the earth. The building thus does not get the benefits of these rays. Water should be sprinkled in the East and the North sides of the plot. Due to this there is a catalytic action and the auspicious rays are absorbed by the land to a larger extent. A site without a underground water resources should be avoided. [2] The under water reservoir should be kept in NE side. No bore well should be there in south or WSW direction. [2] Before constructing a house it should be checked that ground water level is there or not. Ground water keeps the soil hydrated and it is good for vegetation and household daily water uses. Dug the same pit as we mentioned before in soil check test, fill it with water, walk a hundred steps in any direction, and return to pit. If the water level does not decrease then the land is of superior quality. [1] Site Preservation: SA Credit 2- Water bodies and channels Points 2 Water Conservation: WC Mandatory Requirement 1 Rainwater Harvesting, Roof & Non-roof   Landscape Design: WC Credit 1- Design landscape to ensure minimum water consumption. Points 2   Rainwater Harvesting, Roof & Non-roof WC Credit 3- Enhance ground water table and reduce municipal water demand through effective rainwater management. Case B: High Ground Water Table Points 3   Water Metering: WC Credit 6- Encourage sub-metering to improve water performance of the building, and thereby save potable water. Points 2

11. VAASTU V/S green building VASTU IGBC CODE ELEMENT - FIRE (Solar Energy)   East South West is considered as the solar kingdom. During sunrise, for the first 2- 2.5 hours, the sun provides energy for promotion of life. It lies in the East direction and its primary energies are good for existence of all life forms. The next three hours it starts radiating more and more energy in the environment and is called the state of Agni (fire). This is the time when it starts moving on its mission gradually, providing negative effects. During this period, the sun lies in the Southeast zone. The next three hours, in its third phase, a complete glow and aura of the sun starts coming out with its full force and energy. [2] We should never construct a wall in the middle portion of a house. This part is called Brambhasthan . The owner of the house must take all necessary steps to ensure that this place should always be vacant. [1] Light is one of the main element among other five elements of vastu . The east side belongs to lord Indra . Light source and its energy is necessary to the residents inside a house. North and northeast side should be kept open to path a proper path to enter early sunshine. Less door and window should be in south and south west direction, as positive to negative energy travels from N, NE side to S,SW direction respectively. [2] Sustainable architecture and design Passive Architecture: SA Credit 3- Adopt passive architectural design features to minimise negative environmental impacts. Exterior opening, Daylight, Skylight Points 2   ENERGY EFFICIENCY Minimum Energy Efficiency: EE Mandatory Requirement 2- Optimise energy consumption, to reduce negative environmental impacts from excessive energy use. The Lighting Power Density (LPD) in the building interior, exterior and parking areas shall be reduced by minimum 10% over ECBC base case.   Enhanced Energy Efficiency: EE Credit 2- Optimise energy consumption, to reduce negative environmental impacts from excessive energy use. 2) Lighting: Lighting Power Density, Lighting Controls Points 3   Energy Metering and Management: EE Credit 6- Encourage sub-metering and continuous monitoring to identify improvement opportunities in building’s energy performance. Points 1   INDOOR ENVIRONMENTAL QUALITY Daylighting: IEQ Credit 2- Ensure connectivity between the interior and the exterior environment, by providing adequate daylighting. Points 2   Outdoor Views: IEQ Credit 3- Ensure connectivity between the interior and the exterior environment, by providing adequate views. Points 1

12. VAASTU V/S green building VASTU IGBC CODE ELEMENT - AIR (Wind energy)   Doors and windows are the main source of airflow in a house. Doors should be not too large or to small, but always it should be twice or more than twice of its width. There should be no barrier in front of main entrance. If the main road is north side of the house then the entrance door of the house should be on east side; connecting the road with a small pathway. [2] Take a fistful of sand and blow it into air, if the sand falls at the same place, then the land is inferior. Falls some distance away, then the land is mediocre. Goes up in the air, then the land is superior. The land gives results as per flow and speed of sand. [1] ENERGY EFFICIENCY Minimum Energy Efficiency: EE Mandatory Requirement 2- Optimise energy consumption, to reduce negative environmental impacts from excessive energy use. EE Mandatory Requirement 3- Verify and ensure that the building’s equipment & systems are commissioned to achieve performance as envisaged during the design stage.     INDOOR ENVIRONMENTAL QUALITY Minimum Fresh Air Ventilation: IEQ Mandatory Requirement 1- Provide adequate outdoor air ventilation, to avoid pollutants affecting indoor air quality.   Minimise Indoor and Outdoor Pollutants IEQ Credit 4- Minimise the exposure of building occupants and maintenance team to hazardous indoor and outdoor pollutants, which adversely affect indoor air quality and occupant health. Points 1   Low-emitting Materials: IEQ Credit 5- Encourage use of materials and systems with low VOC emissions, to reduce adverse health impacts on building occupants. Composite Wood Points 1   New Wood furniture Points 1   Indoor Air Quality Testing, After Construction and Before Occupancy: IEQ Credit 7- Avoid occupant’s exposure to indoor airborne contaminants before occupying the premises, to reduce the adverse health impacts on building occupants. Points 2

13. VAASTU V/S green building VASTU IGBC CODE SPACE (Cosmic Radiation)   Radiation test- Place a gold and copper coloured flower in a pit. Check for the freshness of the flower, which will decide the land suitability for the corresponding genus. [1] Chajja(sunshade) must be projected equally on all sides of the building. SITE SELECTION AND PLANNING Heat Island Reduction, Non-roof: SSP Credit 6- Minimise heat island effect so as to reduce negative impact on micro-climate Points 2   Heat Island Reduction, Roof: SSP Credit 7- Minimise heat island effect so as to reduce negative impact on micro-climate Points 2   VASTU IGBC CODE OTHERS   The temple should be north or northeast side of the house, facing idol to south. Daily prayer cause mental happiness and increase concentration. [1] If the plot is square, the energy level inside the plot is obtained in proper proportion beneficially. If the plot is rectangular, energy level is obtained at a medium level. Of course, for travelling from the North- East to the South -West corner the energy waves have to cover more distance. Due to this intensity of the magnetic field is reduced. However if the Energy Level Inside the Plot E-SE E E-NE ratio of length and breadth is 2:1 in the rectangular plot a good magnetic field can be created. The energy inside the plot flows from + ve to - ve (that is from a higher level to a lower level). However, the Southwest corner should be at the highest and the North -East corner at the lowest level. [2] INDOOR ENVIRONMENTAL QUALITY Occupant Well-being Facilities: IEQ Credit 6- Provide occupant well-being facilities, to enhance physical, emotional and spiritual well-being of building occupants. Points 1  

14. From this study, the following conclusions can be made, 1. If a house is constructed, only maintaining all the vastu guidelines, it itself can awarded 37 points according to IGBC code. And after considering remaining IGBC codes, which doesn’t conflict with vastu principal then another 24 to 31 points can also be credited based upon the situation. So the building can easily achieve a Gold rated certification. 2. It can also be concluded that vastu concept is not at all only based on pointing out the direction and to show the spiritual aspect or religion. It’s applicable for all kind of human beings as well as it has a strong scientific explanation behind it. 14 Slide Title conclusion
