Make your home energy efficient

You can design an energy efficient and environment friendly house/home by utilizing natural light and ventilation. You can opt for natural ways to do activities at home. Here are given a few ways to make home energy efficient and environment friendly.

• Get maximum solar heat and ventilation to save energy: Solar heat coming from your doors and windows during winter can save up to 10% energy used for heating rooms. Similarly cut your cooling bills in summer by preventing solar heat from entering the rooms/ house by hanging blinds, curtains and by providing shades on doors, windows etc. Fix windows towards the flow of natural air and fix exhaust fan into the opposite direction to remove polluted air out and to minimize energy bills.
• Apply thermal insulation technique on walls and roof: Thermal insulation method saves energy bills during summer and winter season. The insulation on all outer walls of the house minimizes weather effects and saves energy.
• Insulate roof to save energy: The roof of the house should be insulated to save energy because the roof receives solar radiation throughout the day. The top treatment can be done on roof in two ways i.e. Thermal insulation and Damp proof course.

Ventilation Guidelines While Designing Building

•Construct building at 90 degrees angle to the direction of wind. Enjoy maximum wind by constructing building ranging from 0 degree to 30 degrees.
•Take solar heat while constructing the building in case the wind prevails in the East and the West.
•Provide low level windows in the direction of wind flow. Also keep the position of windows according to the components of building.
•Arrange openings of windows in such a way that they provide maximum light in occupancy area.

•Locate outlet openings at high level in opposite direction of wind flow. Keep inlet and outlet area at equal level to get maximum air flow.
•Keep the height of window sill 2’ to 2-1/2 ‘from floor level to get maximum natural air. The height of sill should be 1’-1/2’ from floor level in buildings where persons are working or sitting on the floor.
•Keep opening 

area 20 to 30% of floor area. The area of opening should be 30 to 50 % of floor area where the wind is quite constant.
•Provide open space around the house to get maximum natural air and light where the flow of wind low.
•Fix two windows instead of single one in the room which has only exposed wall.
