Energy Audit plays a critical role in helping clients justify both the economic and environmental benefits of facility upgrade projects. With energy and operational expenses accounting for nearly 75% of a building’s lifecycle cost over 40 years—and energy alone representing about 30% of annual operational budgets—our Energy Audit services provide the insights needed for informed and strategic decision-making.
We deliver comprehensive analyses of facility components affecting energy consumption, enabling organizations to optimize performance, reduce costs, and enhance corporate sustainability. ENERSIS also supports clients throughout the Energy Audit Conditional Grant (EACG) application process, providing end-to-end guidance until results are finalized.
Under the Efficient Management of Electrical Energy Regulation 2008, installations consuming ≥ 3,000,000 kWh within any six consecutive months are required to appoint a Registered Electrical Energy Manager (REEM).
Our in-house REEM, registered with the Energy Commission, assists affected organizations in meeting regulatory compliance and achieving energy efficiency goals.
