Energy Audit

Energy Audit

An energy audit is a professional assessment that evaluates how a building uses energy and identifies opportunities to improve efficiency. It examines key building systems—including HVAC, lighting, insulation, building envelope components, and equipment—to identify energy waste, reduce operating costs, and improve overall building performance.

 

The audit provides a detailed report with practical, cost-effective recommendations to reduce energy consumption, lower utility costs, and support sustainability and decarbonization goals. Energy audits can also support Local Law 97 compliance planning, LEED certification, and long-term energy management strategies for commercial, residential, and institutional buildings.

The Energy Audit Process

The energy audit process begins with an on-site assessment, where an energy engineer evaluates utility consumption, building operations, and the performance of key building systems. The assessment typically includes HVAC, lighting, insulation, windows and building envelope components, ventilation, and energy-consuming equipment.

 

Following the site assessment, collected data is analyzed to identify energy inefficiencies and opportunities for improvement. The energy audit report outlines recommended Energy Conservation Measures (ECMs)—such as equipment upgrades, system optimization, and operational improvements—along with estimated energy savings, implementation costs, and cost-benefit analysis to help building owners make informed investment decisions.

Frequently Asked Questions

The duration of an energy audit depends on several factors, including the size of the property, how the building or facility is used, the number of electronic devices and appliances present, and the complexity of the audit being conducted. On average, the walk-through takes around 3 or 4 hours to complete.

Yes, an energy audit is worth it. It can lead to significant cost savings by identifying inefficiencies and recommending improvements that reduce energy consumption. The savings on energy bills often outweigh the initial cost of the audit.

The cost of an energy audit varies depending on the size and complexity of the building and the type of audit. Basic audits may cost a few hundred dollars, while comprehensive audits for large facilities can cost several thousand dollars.
