An energy audit is a professional assessment that identifies how a building uses energy and where it’s being wasted. It covers systems like lighting, HVAC, insulation, and appliances to uncover efficiency issues. The audit results in a detailed report with practical recommendations to reduce energy use, lower utility bills, and improve sustainability. It’s a key step for compliance with Local Law 97 and long-term energy savings.
The energy audit process starts with an on-site assessment, where an energy engineer gathers data on utility usage, building operations, and system performance. Key areas reviewed include HVAC systems, lighting, insulation, windows, appliances, and ventilation. After the inspection, the collected data is analyzed to identify energy inefficiencies and opportunities for improvement. The auditor then provides a list of recommended energy conservation measures—such as system upgrades, efficiency improvements, or operational changes—along with a cost-benefit analysis to guide informed decision-making.
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.
