Presentation on theme: "Architectural designs are at a turning point, when the designers concept focused primarily to energy sustainable buildings. Certifications like LEED provoked."— Presentation transcript:
Visible Light : Electromagnetic radiation at wavelengths which the human eye can see. We perceive this radiation as colors ranging from red (longer wavelengths; ~ 700 nanometers) to violet (shorter wavelengths; ~400 nanometers.) Architectural glass achieve the ability to control the electro magnetic spectrum by depositing wide range of metals or oxides on the surface of the glass. These types of coatings widely known as Low E (Low Emissivity )coatings. Low E are available in different formats based on the performance of glass. The selection of the right Low E is required to get the optimum result of the energy saving in a building. Please see the comparative chart below. If you use HP Low E you can cut down the Heat gain by 60%.

By cutting down the heat gain, you reduce the Air Conditioning Load in the building, result is energy saving. KEY WORD Glasses which“ appear “ to look alike do not necessarily provide the same performance ! GGI can assist you in identifying the right glass for your projects
