Architects can help create more sustainable cities by designing buildings that use less energy. One of the efficient methods of reducing the energy required for air conditioning and electrical lighting is by controlling how much direct sunlight enters a building. Sustainable architecture consider and incorporates solar control methods while designing green buildings.
The intelligent use of solar shading like venetian blinds, roller shades, brise soleil, and louvers - horizontal or vertical also helps in reducing energy usage. The need for air conditioning is also minimized by cutting down on the amount of direct sunlight that enters a building at the exterior glass wall. Similarly, the need for artificial lighting is also eliminated all through the day by using these installations.
