According to Directive 2012/27/EU of european parliament and council, energy audit is "a systematic procedure with the purpose of obtaining adequate knowledge of the existing energy consumption profile of a building or group of buildings, an industrial or commercial operation or installation or a private or public service, identifying and quantifying cost-effective energy savings opportunities, and reporting the findings;"
AESS provides energy auditing services on public building stocks with the aim of outlining the energy saving potentials and options. The Energy Audit is performed on the building components and its systems: its goal is to estimate the overall energy balance and identify the main energy flows.
The Audit may be carried out on two main degrees of in-depth analysis according to the goal:
- the so-called “type A” audit, that provides highly-accurate data which con be used as input for energy performance contracts
- “type B” audits, that represent the preliminary assessment which allows the decision-maker to focus on a limited set of possible refurbishment actions.
