Designing the vertical fenestration of a building is a critical aspect of energy-efficient building design. Vertical fenestration, which includes windows, doors, and other glazed areas on the walls of a building, can significantly impact a building’s energy consumption and occupant Read more
n building construction, determining the overall U-value (thermal transmittance) of walls is crucial for ensuring energy efficiency and thermal comfort within a building. The U-value of a wall represents the rate of heat transfer through the wall, including conductive, convective, Read more
The overall heat transfer coefficient (U-value) is a measure of a material’s ability to conduct heat. It indicates the rate at which heat flows through a specific material, from the warmer side to the cooler side. The U-value of a Read more
Daylight simulation can also be conducted manually for projects that adopt the prescriptive compliance approach. The following example demonstrates how to calculate the daylight extent factor (DEF) for a building located in Delhi and how to use this factor to Read more
A 7,200 m2four story office building in Delhi is trying to achieve ECBC levelcompliance. Building is oriented along east west axis. It has a rectangular layout (60 m x 30 m). Totalbuilt up area is distributed evenly across all floors Read more
Building envelope sealing is a crucial aspect of building construction that is often overlooked. A building envelope is essentially the barrier between the conditioned interior environment and the exterior environment. It is the first line of defense against the elements, Read more
Daylight simulation is an important method for evaluating the daylighting performance of a building, which involves the use of specialized software to simulate the amount of natural light that enters a building’s interior. The Energy Conservation Building Code (ECBC) of Read more
Daylighting is the use of natural daylight to light up the interior of a building, reducing the reliance on artificial lighting sources. It is a vital aspect of sustainable building design, and it has several benefits, including energy conservation, improved Read more
Visual Light Transmittance (VLT) is a measure of the amount of visible light that passes through a fenestration product such as windows, skylights, and doors. VLT is expressed as a percentage of the total visible light that strikes the surface Read more
Solar Heat Gain Coefficient (SHGC) is a critical metric used in the building industry to determine the amount of solar radiation that enters a building through its fenestration system, including windows, doors, and skylights. It is defined as the ratio Read more
