Energy Audit

What is Energy Audit?

An energy audit is an evaluation of a building’s energy use to identify inefficiencies and recommend cost-saving improvements.

Description

An energy audit is a systematic assessment of a building’s energy consumption, performance, and efficiency. It analyzes how energy is used for heating, cooling, lighting, and equipment, and identifies areas where energy is being wasted or could be improved.

In construction and building operations, energy audits are commonly performed on existing buildings, but they may also be used during design or commissioning phases. Audits can range from basic walkthrough assessments to detailed analyses involving utility data review, blower door testing, infrared thermography, and equipment performance evaluations.

From a cost and sustainability standpoint, energy audits help owners and facility managers prioritize upgrades that reduce energy use, operating costs, and environmental impact. Many energy codes, incentive programs, and green building certifications encourage or require energy audits as part of ongoing building performance management.
