Energy audit

Energy audits are undertaken to assess energy use and propose measures that might be taken to reduce consumption and costs.

The Carbon Trust suggest that 20% of business' annual energy costs are wasted by energy inefficient equipment, however, businesses often focus on revenue rather than costs and so 60% of cost-effective, viable, energy efficiency recommendations are not implemented. (Ref Carbon Trust, Mandatory energy efficiency audits for business. December 2013.)

An energy audit might be undertaken for a single building, several buildings, a site or an organisation, and might be carried out for commercial or domestic clients.

An energy audit might provide:

Typically, savings might be identified through assessment of:

Energy audits can be carried out in-house if there is sufficient expertise, or external advisers (such as energy surveyors) may be appointed. Organisations such as the Carbon Trust provide accreditation for energy surveyors.

Article 8 of the European Union (EU) Energy Efficiency Directive (2012/27/EU), requires that member states introduce regular energy audits for large enterprises with more than 250 employees or a turnover exceeding €50m (ie enterprises other than small and medium-sized enterprises (SMEs)). This is intended to encourage the uptake of cost-effective energy efficiency measures. These audits must be undertaken by 5 December 2015, and then every four years after that. The scheme does not extend to public bodies and does not require businesses implement the energy saving recommendations.

In the UK , the government propose that the directive should be implemented through the Energy Savings Opportunity Scheme (ESOS). See Energy Savings Opportunity Scheme for more information.
