Certified Energy Auditor Practice Exam

The Solar Heat Gain Coefficient (SHGC) is a crucial measurement in energy efficiency and building design, particularly when considering windows and other fenestration products. It specifically quantifies how well a product blocks heat from the sun, making it a valuable tool for assessing how much solar radiation can be transmitted through windows and doors into a building.

A lower SHGC indicates that a product is highly effective in blocking solar heat gain, which is particularly important in warmer climates or during hot months, as it can help in reducing the demand for air conditioning and improving overall energy efficiency.

Understanding the SHGC is essential for architects, builders, and energy auditors when designing buildings that maintain a comfortable indoor environment while minimizing energy consumption. By choosing products with appropriate SHGC values, it is possible to enhance energy efficiency significantly and contribute to sustainability goals.
