Key Implementation Decision – New Buildings

no	Key Implementation Decision – New Buildings	Description / value / response	Comments
02.01	Are building codes set as overall value, primary energy, environment (CO₂), reference building or other?	Primary energy in kWh/(m².year)	Defined as energy class to be met and also as NZEB requirements to be met
02.02	Requirements for energy performance of residential buildings in current building code	As above	As above
02.03	Requirements for energy performance of non-residential commercial buildings in current building code	As above	As above
02.04	Requirements for energy performance of non-residential public buildings in current building code	As above	As above
02.05	Is the performance level of nearly zero energy (NZEB) for new buildings defined in national legislation?	Yes	Not directly as a number in kWh/(m².year)
02.06	Nearly zero energy (NZEB) level for residential buildings (level for building code)	Yes, indirectly	Calculation of the energy performance is based upon comparison with the reference building. The reference NZEB has stricter requirements on the building envelope (0,7x U_m,R (average U-value) and a reduction in primary energy compared to the reference building)
02.07	Year / date for nearly zero energy (NZEB) as level for residential buildings (as indicated in 02.04)	1 January 2020
02.08	Nearly zero energy (NZEB) level for all non-residential buildings (level for building code)
02.09	Year / date for nearly zero energy (NZEB) as level for non-residential buildings (as indicated in 02.06)	1 January 2020
02.10	Are nearly zero energy buildings (NZEB) defined using a carbon or environment indicator?
02.11	Is renewable energy a part of the overall or an additional requirement?	Yes, indirectly	Based on calculation
02.12	If renewable energy is an additional requirement to NZEB, please indicate level	Not in kWh/(m².year)	Depending on used technical building systems and building envelope quality
02.13	Specific comfort criteria for new buildings, provide specific parameters for instance for airtightness, minimum ventilation rates	Indirectly	Specific comfort criteria can be found in Czech standards For example, Czech standard ČSN 73 0540-2 defines airtightness depending on the type of ventilation systems used, the intensity of air exchange in the used room, the thermal stability, etc.

Key Implementation Decision – Existing Buildings

no	Key Implementation Decision – Existing Buildings	Description / value / response	Comment
03.01	Is the level of nearly zero energy (NZEB) for existing buildings set in national legislation?	No	The building owner can, however, ask the EPC issuer to prepare recommendations in order to meet the NZEB requirements (even though not set as legislative requirements for renovations).
03.02	Is the level of nearly zero energy (NZEB) for existing buildings similar to the level for new buildings?	Yes, partly	In case of a change of an existing building, when the total energy reference area expands to at least two and a half times the original total energy reference area, NZEB requirements must be met for the whole building.
03.03	Definition of nearly zero energy (NZEB) for existing residential buildings (if different from new buildings)	No	-
03.04	Definition of nearly zero energy (NZEB) for existing non-residential buildings (if different from new buildings)	No	-
03.05	Overall minimum requirements in case of major-renovation	Yes	Combination of energy performance indicators must be fulfilled by either: primary energy and average U-value or total delivered energy per year and average U-value or U-value of each construction element within the system boundary and energy efficiency of the technical building systems
03.06	Minimum requirements for individual building parts in case of renovation	Yes
03.07	National targets for renovation in connection to Long Term Renovation Strategy (number or percentage of buildings)	Yes	See the table in section 2.II.iv.
03.08	National targets for renovation in connection to Long Term Renovation Strategy (expected reductions and relevant years)	Yes	See the table in section 2.II.iv.
