Glass and Orientation for Green Buildings:- Glazing of a green building should reflect harmony of daylight and shading, views and protection, energy conservation, cost of material as well as highlight the individual character of the building. The usage of high performance glass contributes towards achieving several points in the LEED rating system, and helps reduce energy consumption as well as increase the comfort of occupants. Glass selection for a Green Building has to be a well thought out affair to maximize the benefits from the glazing. Low quality glass would increase energy consumption for air conditioning unnecessarily, while a darker glass would increase artificial lighting load. Also the design of glazed areas in the building has great impact on energy consumption - daylight as well as maintenance costs too. An excellent design of a green building with respect to glazing requires a dedicated architect and inputs from the glass manufacturer, the green building consultant and a façade consultant.
