If you want to make your building more energy-efficient, then an energy audit is the first step in identifying energy-savings and energy cost reduction opportunities, reduce greenhouse gas emissions and improve the comfort, health and safety of the occupants.
An energy audit takes a detailed look at your building’s energy consumption data as well as energy-using systems and equipment, such as lighting, mechanical systems, electrical loads and building envelope.
The American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE) has defined three levels of energy audits:
ASHRAE Level I: Walk-through assessment
If you are looking to prioritize energy efficiency projects and want to determine if a more detailed audit is necessary, then this audit may be right for you. An ASHRAE Level I audit includes an analysis of the building’s utility bills, operating data and a walk-through of the facility. The Level I audit identifies and provides savings and cost analysis of low-cost/no-cost measures and potential capital improvements.
ASHRAE Level II: Energy Survey and Analysis
This audit builds on the findings from the Level I audit and provides more detailed information and analysis of individual building systems, their operation and interaction with other systems. A detailed report will include Energy Efficiency Measures (EEMs), modifications to system controls and building automation, operational changes and potential capital upgrades and will include cost and performance metrics. An ASHRAE Level II is helpful for validating project implementation.
ASHRAE Level III: Detailed Analysis of Capital-Intensive Modifications
For major capital investments, an ASHRAE Level III audit may be required. This is the most comprehensive energy audit and will provide detailed technical engineering information, costs, energy savings and economic indicators for the energy conservation methods studied.
