The certificate of energy performance of a building is a document prepared according to the methodology for calculating the energy performance of buildings, through which is indicated the energy performance of a building or building unit and includes data on energy consumption in buildings and which, as the case, may be accompanied by recommendations to reduce them.
The document is issued by the Building Energy Auditor, at the request of the owners or managers of buildings, and is valid for 10 years from the date of issue shown on the certificate, unless for the building which has an available certificate in which major renovations are made to change its energy consumption.
Thus, for buildings or building units which are sold or rented, the owner is obliged to provide the prospective buyer or tenant, as applicable, prior to perfecting the contract, a copy of the certificate, so they can know about the energy performance of the building that is going to buy or rent, as applicable.
Also, at the conclusion of the contract of sale, the owner is required to submit the certificate, in original, to the new owner. At the date of registration of the contract of sale, or lease, the owner is required to submit to the tax authorities a copy of the certificate and the original will remain in possession of the owner.
Contracts of sale concluded without energy certificates are subject for relative nullity, according to the Civil Code.
The growth of energy performance of buildings by designing new buildings with low energy consumption and thermal rehabilitation of the existing buildings, as the correct information of building owners / managers through energy performance certificate, are shares of general public interest and, in the context of energy saving in buildings, of improving the built urban frame and environment protection, reads the text of Law no. 159/2013 amending and supplementing Law no. 372/2005 on the energy performance of buildings.
Buildings that do not have mandatory energy performance
The certificate is not required to buildings and protected monuments from protected built areas, by law, or have special architectural or historic value, because if they would apply the requirements, they would unacceptably alter the character or exterior appearance.
Also, the document is not required for buildings used as places of worship or other religious activities, for temporary buildings intended to be used for periods of up to two years, from industrial areas, workshops and non-residential buildings in the field of agriculture that require reduced energy consumption, for residential buildings which are intended to be used less than four months a year, for independent buildings with a usable area of less than 50 square meters.
Energy performance rated from 1 to 100
The energy performance of a building / building unit is expressed, mainly, through the following performance indicators: a) energy class b) total consumption of specific energy, c) index of CO2 equivalent emissions, according to Article 5 of Law no. 159/2013 amending and supplementing Law no. 372/2005 on the energy performance of buildings.
The energy performance of a building is expressed by a grade from 1 to 100, which is even higher when the building has a higher energy efficiency.

Also, energy performance is expressed through employment in one of the seven classes, from class A characterized by the lowest energy consumption, ie consumption up to 125 kWh / m² / year, to class G, corresponding to the highest power, ie over 820 kWh / m² / year.
