Solar Heat Gain Coefficient & Fenestration

The main focus is on solar heat gain and its effects on the thermal performance of buildings and energy costs for heating and cooling, also includes studies of daylight illumination including performance assessments of complex piped systems.

Due to Hyderabad's generally hot climate, a special focus is on applications for such climates. This includes a variety of shading devices, including those separated from, attached to, or incorporated within a window system.

Advanced glazing systems intended for hot climate applications are also provided. It is best if such glazings are spectrally selective, meaning that they reject the invisible parts of the incident solar spectrum while transmitting the visible portion, thereby lowering solar heat gain while admitting daylight illumination. We have a special interest in spectral selectivity for this reason, and originated a useful measure of spectral selectivity: the Light-to-Solar Gain Ratio, or LSG ratio, now recognized by the window industry as an important attribute of glazing systems.

The processes involved in admitting solar heat and light into Residential and Non-Residential buildings are somewhat complex and technical in nature. We do field work on residential energy performance, including assessments of fenestration impacts on that performance. We also offer consultancy on stand-alone fenestration issues and on more general aspects of building design for energy performance, which have components on the performances of envelope systems, including fenestrations.

Computer programs useful for designing buildings, windows, and shading systems are also available from a variety of sources. Some fenestration-related software is available for free download.

Most residential buildings consists of single-family homes with clear, single-pane, aluminum frame windows
