According to the Law of Ukraine "On Energy Efficiency of Buildings," energy efficiency certification is mandatory for the following newly constructed, reconstructed or subject-to-capital-repairs objects:

• Buildings and structures that are regarded as objects of medium (so-called "CC2") and significant ("CC3") consequences
• State and municipally owned buildings that have over 250 square meters of heating area hosting state and municipal authorities or that are regularly attended by citizens
• Buildings and structures that receive state support for enhancing energy efficiency

This is except for cases when the types of buildings or works are explicitly exempted from mandatory energy efficiency certification by the Cabinet of Ministers of Ukraine. Owners of these exempted properties may still apply for voluntary energy efficiency certification.

Energy efficiency certification leads to the issuance of an energy certificate by a respective energy auditor. This certificate is issued electronically (via the Unified State Electronic System in the Sphere of Construction) and is valid for 10 years as of the day the relevant registration number is assigned (unless this certificate is substituted with a new one). This certificate contains, among other things, information on the building's class of energy efficiency, volumes of energy consumption, pollution volumes, a description of the building and recommendations on increasing its energy efficiency.

The Ministry for Development and Communities and Territories of Ukraine establishes the minimum standards of energy efficiency (which are subject to review every five years) in accordance with the State Construction Standards. There are six energy efficiency ratings for buildings. The buildings with the best qualities are rated "A" class, whereas ones with the worst characteristics are rated "F" class. If the energy audit reveals that a building is a "D" or an "F" class, the building's energy efficiency must be improved to reach the "C" class.

Under the Law of Ukraine "On Town Planning," the design documentation for buildings of the CC2 and CC3 classes of consequences is subject to a mandatory state energy-saving expert review. Failure to comply with this requirement may result in an administrative fine and may affect the commissioning of the building. For all other buildings, the state energy-saving expert review is voluntary.

With regard to voluntary energy performance certification, some local authorities have joined a system of voluntary energy certification of buildings, including multi-apartment residential buildings, schools, health centers, etc. This voluntary energy certification is supported by the European voluntary energy certification system "Display Campaign," which was developed in 2003 by energy experts from European towns and cities.
