An energy audit is the process of systematically assessing the energy management of a building, site, business or other entity to identify opportunities for energy savings. This audit provides a detailed analysis of current energy consumption and proposes measures to reduce energy consumption that are also cost-effective.
Obligation to carry out an energy audit
According to Act No 406/2000 Coll., on energy management. An amendment to Decree No. 140/2021 Coll. stipulates the requirements of an energy audit. The decisive factor for the obligation to prepare an energy audit of buildings or equipment is the total annual consumption of all types and forms of energy at all consumption points operated under one organisation identification number (I.N.).
- for organisational units of the state, regions, municipalities and their contributory organisations from an average annual energy consumption of 500 MWh i.e. 1 800 Gj
- for entrepreneurs who employ 250 or more persons or have an annual turnover of CZK 1.3 billion or an annual balance sheet total exceeding CZK 1.1 billion
- for an entrepreneur whose average annual energy use for the last 2 consecutive calendar years exceeds 5 000 MWh
Validity of the energy audit
Valid for 10 years or until an energy management change has been made after which there has been a change of more than 25% in the energy management of the energy management per year compared to the status of the current EA.
- 4 years for large companies with over 250 employees and a turnover of CZK 1.3 billion
- 10 years for enterprises that do not fall into the first group but have an annual energy intensity of more than 5 000 MWh
Municipalities or entrepreneurs who do not want to have an energy audit must have an energy management system in place and certified by an accredited person according to ČSN EN ISO 50001.
