A Building Energy Audit is a systematic evaluation of a building's energy use and efficiency. It identifies areas where energy is wasted and suggests improvements to reduce consumption. This process typically involves analyzing energy bills, inspecting equipment, and assessing insulation and lighting. The audit helps building owners and managers understand their energy performance and make informed decisions about upgrades or retrofits. By implementing the recommendations from the audit, facilities can lower energy costs, enhance comfort, and contribute to environmental sustainability through reduced carbon emissions.
