Building Energy Codes are regulations that set minimum energy efficiency standards for new and existing buildings. These codes aim to reduce energy consumption, lower utility bills, and minimize environmental impact. They cover various aspects, including insulation, heating, cooling, and lighting systems. By adhering to these codes, builders and architects can ensure that structures are designed to use energy more efficiently. Compliance with Building Energy Codes can also lead to improved indoor air quality and increased comfort for occupants, contributing to a more sustainable built environment.
