Existing legal framework had to be evaluated in view of the Directive on Energy Performance in Buildings (EPBD), the requirements of which are to be met for new and existing buildings starting 4 January 2006, and certification procedure set for the required set of buildings.
The achievements of the project in the EPBD implementation in the Czech Republic can be summarised as follows:
- Changes were proposed to the Energy Management Act (EMA) so that the requirements of the EPBD were fully reflected in the Act. The updated draft Act is under approval procedure in the Parliament;
- The executive decree to the draft Act (EMA) transposing the Article 8 and 9 of the EPBD has been developed and submitted to the Ministry of Industry and Trade;
- The framework for implementation of the Articles 3 to 7 of the EPBD has been proposed:
· The integrated indicator for the energy performance of a building was selected and proposed – a weighted sum of delivered energy per annum (GJ/a). Weighing factors were proposed.
· Methods for calculating the indicator and the individual energy consumptions per energy use were proposed, these being advanced degree-day method (mainly Implementing EU Directives on Energy Efficiency in to the Czech Republic for family houses and simple residential houses, and other simple buildings) and monthly method for all more complicated buildings using e.g. cooling, artificial ventilation ad heating at the same time.
· As to rating of the buildings, asset rating was proposed to be used for new and reconstructed buildings, while operational rating was proposed for buildings when sold or rented and for public buildings.
The framework for implementation of the Articles 3 to 7 of the EPBD has been proposed:
· Buildings to be exempt from the requirements were defined, the energy certificate proposed – both written and graphical part of the Certificate;
· Both asset and operational rating were described and explained and also the relevant CEN and Czech standards;
· The environmental, technical and economic assessment of alternative systems has been proposed based to a large extent on already existing practice in energy auditing in buildings; this will have to be performed for all new buildings above 1000 m2 as a part of the certification procedure. Dimensioning of individual systems has been left to the relevant CEN standards;
· Energy efficient measures in buildings have been summarised and a list of recommended measures in individual energy uses was developed to be considered in existing buildings under reconstruction and in case of the building certification. Economic evaluation of the energy saving measures was proposed.
Article 3: Adoption of a methodology
The methodology is at national level (act no. 406/2002, as amended, regulation no. 291/2001 of the Collection of laws of the Czech Republic)
These building types are covered:
- all buildings financed by public sources,
- buildings financed by private sources with energy consumption higher than 700 GJ/year
Assessment type:
- specific heat consumption
The regulation is fully implemented
Assessment method:
- The assessment method is evident in the regulation no. 291/2001 of the Collection of laws of the Czech Republic
Technical items:
- The indicator of the methodology is the final energy consumption
Article 4: Setting of energy performance requirements
The energy performance requirements is evident in the act no. 406/2002, as amended, regulation no. 291/2001 of the Collection of laws of the Czech Republic.
Article 5: New buildings
All new buildings financed by public sources and new buildings financed by private sources with an energy consumption higher than 700 GJ/year are concerned by the regulation.
The compliance is checked before construction.
Description of the type of requirements:
Energy consumption, for new buildings over 1000 m² of the floor area the certificate must include the outcomes of assessment of technical, environmental and economic feasibility of alternative systems of heating - decentralised supply of energy from renewable sources, CHE, distant and block heating and heat pump.
The constraint that the regulation include is an efficiency set by Czech regulation no. 291/2001, 152/2001.
These renewable energies and advanced energy technologies are approached:
- Energy from renewable sources
- CHE
- Distant and block heating
- Heat pumps
Article 6: Existing buildings
By renovations of more than 25% of the building skin or more than 25% of difference in energy consumption the same regulations are applicable.
Article 7: Energy performance certificate
The regulation has a national application range.
Energy performance certificates has a validity of 10 years.
The applicability range of the energy performance certificate according to the building type:
- New buildings, major renovation of the buildings of more than 1000 m² floor area, which affect energy demand; exceptions - proof by the energy audit of unavailability according to lifetime of the building or special regulations (e.g. historical buildings), lifetime to 2 years, experimental buildings, partly used buildings (above all religious use), used less than 4 months a year and buildings with floor area less than 50 m²
The compliance is checked by independent specialists-energy auditors and state energy inspection.
Article 8: Inspection of boilers
The inspection of boilers:
- is done by authorised specialist according to the act no. 86/2002 about air protection
- it is done according the air protection legislation - government regulation no. 352/2002 - separately for small, medium and big boilers
Expert advice:
There are grants from state budget for the education and counselling in the field of dealing with energy, there are many centers and agencies supported by Czech energy agency.
Article 9: Inspection of air conditioning systems
Obligation to check every 4 years the cooling systems of an effective rated output greater than 12 kW.
