An energy audit consists of four main steps.
1. Current energy bills are analysed to determine trends, evaluate breakdown by end use (e.g., heating, lighting) and compare to similar facilities.
2. Site inspections and measurements assess the condition and efficiency of equipment and identify opportunities for reducing energy use.
3. The technical and economic feasibility of each measure is determined. Annual energy savings are calculated using building energy simulations and spreadsheet calculations. The cost of measures is estimated using supplier and contractor quotations, pricing handbooks and from our experience with similar projects.
4. An action plan is prepared for those measures with an acceptable payback period. The plan identifies the total retrofit cost and annual savings and describes the implementation steps.
Enermodal has undertaken close to 100 building energy audits that include all building types. We are approved for conducting energy audits under Natural Resources Canada's Energuide Program
