What is building orientation.pptx

The word ‘building orientation’ is basically the positioning of a building with respect to the sun, usually done to maximize solar gain at the appropriate time of the year when required in a cold climate and to minimize solar gain in a hot climate.

2. What is building orientation? The word ‘building orientation’ is basically the positioning of a building with respect to the sun, usually done to maximize solar gain at the appropriate time of the year when required in a cold climate and to minimize solar gain in a hot climate.

3. How can I maximize the daylighting of my building design ? To maximize the daylighting of a building design, the building must be incorrect alignment with the sun. Sunshine entering the rooms in the autumn and winter, and in the morning is preferable. Sunshine at midday and in the afternoon in the summer is not preferable.

4. Sun path Northern Hemisphere Southern Hemisphere Near Equator

5. Sun path The fact is that the sun is lower in the sky in winter than in summer allows us to plan and construct buildings that capture that free heat in winter and reject the heat in summer. The building orientation of the whole building plays an important part in designing a good home.

6. Importance of Building Orientation in Architecture The word ‘building orientation’ is basically the positioning of a building with respect to the sun, usually done to maximize solar gain at the appropriate time of the year when required in cold climate and to minimize solar gain in a hot climate. Best house orientation can increase the energy efficiency of your home by making it more comfortable to live in and cheaper to run from energy consumption point of view.

7. Aim of Building Orientation The chief aim of the best house orientation is to provide physically and psychologically comfortable living inside the building to give good health & happiness to the user in a secure way.

8. Building Orientation East and west receive maximum solar radiation during summer. West is a crucial orientation because high intensity of solar radiation is received during evening hours, when the internal gains are also at its peak. Therefore, Deep verandahs or sunshades in the south and west facades would effectively exclude these strong evening rays.

9. Building Orientation The most frequently used rooms during the day are oriented in the East and the North whereas the rooms that are used mostly at night are restricted to the South and the West, which are hotter directions.

10. Building Orientation Plan your house windows & doors in the East to allow the Sun’s UV rays to penetrate into the house in the mornings.

11. Building Orientation The orientation of kitchen should be towards the east to allow the UV rays to destroy the germs that tend to multiply in the presence of moisture & food.

12. Building Orientation While deciding the building orientation, one must also take into consideration the location of landscape features in a plot, i.e. trees, planters, etc. which will affect the building depending on sun direction and sun path.

13. Building Orientation Trees and tall shrubs should be planted towards south and west of the site to protect the inmates from the afternoon heat and to provide them with oxygen.The open water bodies in gardens should be kept in the north-east to enable the morning UV rays of the sunlight to destroy germs & bacteria before using it.

14. Exposures in different side

15. 1.Southern exposures Southern light provides warm, ambient light throughout the day and generally feels sunny and comfortable. On buildings, you will typically see sunshades on the south facades to keep the sun out during the summer while allowing it in during the winter when sun angles are lower.

16. …Southern exposures Best spaces : All living spaces, especially those used frequently. Worst spaces : Spaces used infrequently or requiring darkness, such as bedrooms used only for sleeping, bathrooms, storage, and TV rooms.

17. 2. Northern exposures Northern light is indirect, meaning that it is always in shadow and can cause spaces to feel dark and cold. North-facing windows receive the least amount of light of any orientation exterior shading is not required and glare is not a concern

18. …Northern exposures Best spaces : Infrequently used rooms like storage, bathrooms, laundry rooms. Activities that require ambient light but cannot handle glare, such as office spaces and rooms with computer or TV screens, may benefit from northern exposure. Worst spaces: Frequently used rooms and sunrooms.

19. 3. Eastern exposures Eastern light is direct in the mornings, making it ideal for sleeping spaces and breakfast nooks where people spend time early in the day Morning sunlight can have a positive effect on mood, reducing depression and anxiety. Eastern light is warm in the morning and cools in the evening

20. …Eastern exposures Best spaces: Bedrooms, breakfast nooks, spaces used in the morning.  Worst spaces : Spaces that cannot tolerate variable light. 

21. 4. Western exposures Western light is direct in the evenings often causing glare and heat gain issues in the hours before sunset as the lowered sun angle renders many shading strategies inefficient or ineffective. Western light is cool in the mornings and warm in the evenings

22. …Western exposures Vertical sunshades on the exterior are more beneficial on western facades than horizontal shades for this reason, as spaces may overheat in the evenings.  Because western light is variable, it is difficult to control for tasks that require more even lighting (such as work and reading spaces).

23. …Western exposures   Best spaces : Rooms used primarily in the afternoons, such as living rooms. Worst spaces: Spaces that cannot tolerate variable light. Kitchens used in the evenings may have overheating and glare issues with west-facing light. Bedrooms since it is darker in the morning.
