Net Metering allows solar consumers to supply access power back to the grid and reduce their electricity bill. It is a crucial policy decision by any state providing net metering facility. Without it, the widespread penetration of solar rooftop is Read more…
Climate Zone Map of India Climate Zones The first step in following the ECBC is determining the appropriate climate zone of the building site which willdictate the specific requirements for design and construction of the buildingsystems and components. India possesses Read more…
The SHGC and U-factor ratings are the most important items to verify during inspections. Building professionals should verify that the ratings of the installed windows, doors, and skylights meet or exceed the ratings specified on the plans. It is also Read more…
The sun emits visible solar radiation in the form of light and infrared radiation that cannot be seen, but causes heat. Spectrally selective glass transmits a high proportion of the visible solar radiation, but screens out radiant heat from the Read more…
Low-e stands for low-emissivity and refers to a special coating that reduces the heat transfer of a window assembly. Low-e coated products that reduce solar heat gain can be produced by adding a metallic coating either while the glass is Read more…
Prescriptive Requirements for Fenestration Location : Gurugram Climate Zone : Composite (Lat: 28° 42’ N; Long: 77° 54’ E) Building Type : Daytime Use Building Roof Area : 409 m2 Roof Insulation : Rigid Board 25 mm with R = Read more…
Solar PV market is predominantly using Mono crystalline and Poly crystalline solar panels. As the name suggest, Mono crystalline cells are made from a single continuous crystal structure. Mono crystalline panels can be identified visually as the cells appear as Read more…
In recent years we have seen that many commercial buildings are coming up as a whole glass buildings. In Indian context buildings with full glass is not desirable as the larger amount of glazing leads to a huge amount of Read more…
The solar heat gain constant and shading coefficient are interchangeably used as the property of building façade. However, both properties are different. Let us explain the difference between the solar heat gain coefficient (SHGC) and the Shading Coefficient: Solar Heat Read more…
Traditionally, solar modules are made by solar cells with 78*156 mm size. The solar cells are interconnected with ribbons and create strings within the module. Typically, standard PV cell is of 2 W with 8 Amp. current and 0.5 V Read more…
