The document discusses the principles of energy efficient architecture and climate responsive design. It emphasizes modulating building conditions to keep them within the comfort zone throughout the day using landscape, form, materials and other passive design strategies. The goal is to analyze site conditions, climate data, and building program to inform the passive design of the building form, envelope, and energy systems to create sustainable habitats.

1. The idea of Energy Efficient design is to modulate the conditions such that they are always within or as close as possible to comfort zone. Modulations introduced by the landscape,built form,envelope,materials and other control measures bring the conditions within the range throughout twenty four hours cycle. This is goal of Energy Efficient Architecture Energy Efficient Architecture

3. Study of climatic conditions

4. Sun path diagram Sun path-a typical example Vertical and horizontal shadow angle

5. A Annual sun path Hourly sun path

6. Visualising Radiance Data in ECOTECT You can also interrogate this 3D volume using slices at any location in any axis to display contour plots.

7. Sunshade analysis Shaded areas- overheating Optimum location Of sun shading Sun path shape Changes From N to S Sun requirements during winter

8. Vertical cores and structure Zoning for Transitional spaces Zoning for Solar gain Use of atrium Potential of roof/ Ground floor Used as external spaces Blue areas are building areas Blue areas are building areas

9. Humidity, Rainfall and Seasonal variations Annual average Relative humidity Annual avg rainfall Annual seasonal variations

10. FORM Optimum building form For each climatic zone Orientation as well As directional emphasis Vertical core and structures

11. Energy Conserving Electrical appliances Energy saved is energy gained

12. Photovoltaic arrays A panel of-5M X 5M generates 1.8kwh.

13. Plantation Guidelines

14. Shading devices Solar shades Shadings Vertical gardens Awnings Pergolas Trellis Shading films

15. Energy-Conserving Landscapes Selecting Plants Adaptability and Hardiness Wind Control Using Plants to Conserve Energy Windbreaks Wind Channels Landscaping Guidelines

16. Energy Efficient Techniques

17. Water and Waste Management

18. Rainwater collection and purification

19. The plant produces biogas from kitchen waste by using thermophilic microorganisms that flourish in extreme environment Biogas Plant at Trombay .

20. Actual Design considerations with respect to site 1.Green spaces are designed in heirarchy. Central common green space,Space at the centre of clustres,courtyards at the centre of units. 2.Each unit designed around a courtyard. 3. Shopping area segregated to avoid crowding. 4. Minimal road area to avoid traffic.

21. 5.Orientation of the units as per climatic conditions. Units segregated to benefit from sun and wind. 6. Privacy provided to each unit by positioning them accordingly 7. Renewable and waste Management services applied to site.

23. Sun Path and orientation of buildings Buildings oriented to avoid Direct sunlight but to gain Maximum light.

24. Location of buildings as per wind direction 1.Buildings designed to acquire maximum ventilation 2. Green spaces are provided to increase the Cool breezes

25. Design considerations for type A and Type B units 1.Units designed around courtyard with major rooms having view of courtyard.bed rooms on external face provided with green areas and sit out otas. Court yard for each house Open green areas on all sides Vegetable garden in back yard.

26. . Each room provided with sufficient light and ventilation, while central courtyard gives a cool effect to all area. Cross ventilation is provided to every room. 3.South east wall face maximum of direct sunlight so areas mainly as staircase block,toilet areas and parking provided facing that side.

27. Cross Ventilation

28. 4. Court yard provided for each house giving enough privacy ,to be used as cozy sit outs. 5.Natural look given to buildings by using exposed bricks and rough concrete. 6. Enough vegetation provided where the surfaces are exposed to direct sunlight.

29. Enough vegetation Terraces at different levels Vegetable garden Otas outside bedrooms Terraces at different levels Bbc layer over flat slabs Exposed brick walls with rat trap bond Sloping roofs

30. The process of Architectural Design is a complex exercise involving interactive relationships between Parameters of diverse nature and varying magnitudes. A logical process based on quantitative assessment leading to qualitative decisions that respond to economical and ecological context will result in satisfactory environment comfortable to the human beings, A SUSTAINABLE HABITAT CONCLUSION
