• How does the glass helps to built a green architecture?

• The building facade, windows, doors, and skylights can be designed with high performance glass to meet the desired solar heat gain coefficient and U-value requirements. Use of solar control glass in windows, doors, facades, Skylights will reduce the heat from outside and also allows natural light to flow freely, thus reduces the artificial lighting costs.

• How to reduce the Relative Heat Gain?
• In climatic conditions like India, 80% of the total heat gain is due to direct solar radiation and the rest is due to temperature difference between the exteriors and interiors. Thus to reduce the overall Relative Heat Gain (RHG) in tropical climates , it becomes necessary to curtail the incoming solar radiation by the use of solar control glass with high performance solar coatings. Contrary to this in cold climates the emphasis is on glass with low-emissive coatings to reduce the rate of heat loss from interiros to exteriors.
