Energy audits are a series of tests carried out in a building that calculate the efficiency of its heating system as well as the buildings overall efficiency. Depending on the results of an energy audit, the auditor will recommend energy saving improvements including low cost changes, as well as larger upgrades that may be paid back over several years.
Audits take around two to three hours to carry out, their price can also vary between companies. However, if you set up an audit through your utility company you may be eligible for a rebate.
Energy audits are an investment. With the information that they produce, a building can be fitted with systems that will allow it to be heated and insulated extremely efficiently. Over time the cost of these upgrades will be recouped by saving money on the amount of energy that is required to heat or cool the building.
