The Czech Republic is dedicated to achieving the CO2 reduction targets in line with the EU Fit for 55 package, according to the National Action Plan of the Czech Republic in the field of energy and climate, as proposed for update in October 2023. To achieve the energy reduction goals set out by Directive 2012/27/EU on energy efficiency and the revision of Directive 2010/31/EU of the European Parliament and of the Council of 19 May 2010, the Energy Management Act and its implementing regulations are regularly amended.

Since 2020, all new building permits or notifications of a building not requiring a building permit must be substantiated by certain documents concerning energy consumption. As a standard, all newly constructed buildings must be designed to fulfill the requirements for buildings with nearly zero energy consumption. During the construction process, the building authority may require the constructor to provide the EPC (as described in "Energy Performance Certificates and Minimum Energy Standards"), prepared based on the project documentation. Only a specialist authorized by the Ministry of Industry and Trade can prepare the EPCs and carry out subsequent energy audits of buildings.

A number of specific buildings are excluded from the EPC regime. These mainly include (i) buildings that are designated as cultural monuments or are part of a cultural reservation (which covers a significant part of Prague city center), (ii) buildings designed and used for religious purposes, and (iii) relevant major changes in buildings where their owner proves — by means of an energy audit — that it is not technically or economically appropriate to meet the energy requirements with regard to the operational lifetime and purpose of the building. Furthermore, an EPC does not have to be obtained when selling or leasing a building or part of a building if (a) the building concerned was constructed and its latest major construction change was performed prior to 1 January 1947 and (b) the parties involved agree so in writing.
