.What is an energy audit? You’d be surprised at how many people are unable to answer that question! Home energy audits are detailed home examinations that determine:
Where and how energy is being lost in a home.
Which systems in the home are operating inefficiently.
Which cost-effective measures can be put in place to make the home more comfortable, affordable and energy efficient.
There are 2 different types of audits that homeowners can choose to get the maximum home energy audit benefits:
1. Home Energy Survey
A home energy survey is a visual inspection that doesn’t include the use of diagnostic testing equipment. Its purpose is to assess the general energy performance of an existing home including:
Building envelope features (windows, doors, insulation, ducts) and ages.
Heating, cooling and ventilation equipment types, characteristics and ages.
Appliance and lighting characteristics.
Visible moisture issues.
Visible health and safety issues.
2. General Energy Audit
A general energy audit is also known as an energy assessment, standard energy audit or detailed energy audit. It expands on the home energy survey by collecting more detailed information regarding the home’s energy usage, as well as a more thorough financial analysis of its energy costs.
The general energy audit also includes diagnostic testing using specialized equipment such as a blower door test, duct leakage tester, combustion analyzer and infrared camera. These tests are done to determine:
The location and number of air leaks in the building envelope.
How much leakage is occurring from HVAC distribution ducts.
How effective is the insulation inside walls and ceilings.
Any existing or potential combustion safety issues.
