Investment Grade Audits explained
During an Investment Grade Audit, energy auditors conduct an in-depth analysis of the building's energy usage patterns, systems, and components. It is a very detailed investigation, often concentrating on opportunities or issues identified in a previous Level 1 or Level 2 Commercial Energy Audit.
An IGA includes examining the efficiency of HVAC systems, lighting, insulation, windows, and other relevant factors. The auditors collect extensive data on energy consumption, perform engineering calculations, and may use advanced computer modeling to simulate energy savings and project financial returns.
