In a context where energy management has become a major issue, carrying out an energy audit for your home or building is an essential step for homeowners keen to make savings and improve the comfort of their home while protecting the environment.
What is an energy audit?
An energy audit is an in-depth analysis of a property’s energy performance. It identifies potential sources of energy savings and draws up an action plan to improve the quality of the home, in terms of comfort, energy consumption and environmental impact. The audit is aimed primarily at owners of single-family homes andapartment buildings, but can also be carried out for collective housing such as condominiums.
The different phases of an energy audit
Preparing for the audit
Before carrying out the audit, you’ll need to gather a number of elements essential to the analysis. These include :
- Energy bills (heating, electricity, water) for the last three years;
- Floor plans: these will enable the auditor to better understand the layout of the premises and assess the surface area;
- Information on heating and hot water systems: type, brand, power, etc;
- Characteristics of building materials (insulation, woodwork, etc.), if known.
On-site visit
During the on-site visit, the auditor will carry out a series of measurements and observations to establish a precise diagnosis of the home’s energy performance. In particular, he or she will examine
- Building envelope: walls, roof, windows, floors;
- Heating, ventilation and hot water production systems;
- Electrical equipment and lighting;
- Occupants’ energy behaviors.
The energy audit report
After analyzing the property, the auditor will draw up a detailed report presenting the results of the audit. This report will include :
- An inventory of the home’s current energy situation: consumption, costs, comfort, environmental impact;
- An analysis of potential sources of improvement in terms of energy performance;
- Technical and financial recommendations for achieving energy-saving and comfort objectives;
- An estimate of the investment required and the payback period.
