National Highlights Methodology Methodology Certificate History Requirements Requirements Requirements Only asset rating is used in Certification in the Czech Republic. The Energy Audits, a partly voluntary, partly compulsory additionally energy performance evaluation procedure is based on operational rating Only one type of Certificate is used for all building types and both for Energy Performance Certificate and its display version. Energy Audits according to decree 213/2001 were carried out for nearly all public buildings. The audits are much more detailed than the energy certificate. From the audits a number of experienced experts and useful data of the building are available. Same requirements for new and major renovation Minimum requirements for all building components (envelope, heating, cooling, ventilation, lighting) are combined with a requirement on a global indicator (EP) Reference values has to be calculated, if there is no value available for the actual building type. Requirements The reference values for the energy certification are different for all building types (8 basic types are given in Decree, other reference values have to be calculated). Those 8 types are: family house, multi-family house, hotel and restaurant, office building, hospital, educational building, sport facility, shopping building. 2. Legal Framework 2.1. National distinctions of legislation Czech Legal system consists of Laws (which are obviously obligatory) as Primary Legislation. Example: Law 406/2000 Coll. Law on Energy Management (or Energy Management Act). Ministerial Decrees provides the Laws and are the Secondary Legislation in the Czech Republic (obligatory as well). Example: Decree 148/2007 Coll. Energy Performance of Buildings (decree of the Ministry of Industry and Trade). Standards are more technical specifications of the problematic. Standards usually are not obligatory (only recommendation level) but decrees can make them obligatory. Example: CSN Thermal Protection of Buildings, which is obligatory History of energy related requirements National Technical Standard CSN Thermal protection of Constructions and Components. This Standard has introduced thermal resistance of shell construction and brought first energy efficiency related requirements and recommendations. Today s name of this Standard is Thermal protection of buildings. This standard has been changed and updated many times, last updates were in 1994, 1998, 2002, 2005, Most important changes include increase in U-value of constructions (both required and recommended value). These requirements are valid for both newly built and reconstructed buildings and are valid in a parallel with EPBD requirements (decree 148/2007 Coll. Energy Performance of Buildings). Previous decree which has been replaced by decree 148/2007 Coll. on , was a decree 291/2001 Coll. Heat Consumption in building. This decree includes description of construction, building services systems, heat consumption for heating and hot water heating. Another very important document Energy Audit is being made as a very detailed description of building, its systems and technology installed, based on a real consumption which is invoiced (operational rating). Recommendations supported by economical, environmental and technical analysis are a part of it. Energy Audits are

6 Energy certification in European countries 7 based on a decree 213/2001 Coll. Energy Audit which has been revised by the decree 425/2004 Coll. Energy Audits were not/are not replaced by Certificates, they exist in a parallel with them. These audits are compulsory for: public buildings with more than 1500 GJ of overall consumption, for private companies with more than GJ of overall consumption. For others, Energy Audits are voluntary. Energy Audits are very useful as a source of data for Certification building description, type of building and its zones Overview on EPBD implementation In the Czech Republic, there is a complex of legal and technical regulations, requirements and recommendations. Official tool for implementation of EPBD and evaluation of buildings in its meaning is available (National Calculation Tool NKN which had been developed at the Faculty of Civil Engineering of The Czech Technical University in Prague). Organisation of legislation system: Primary Legislation Energy Management Law 406/2006 Coll. Secondary Legislation (compulsory as well, specification of rules given by Law) Decree 148/2007 Coll. Energy Performance in building Decree 276/2007 Coll. Inspection of Boilers Decree 277/2007 Coll. Inspection of Air-Condition Systems Technical Standards (normally voluntary, recommended only) but can be compulsory if it is so given by Law or Decree - it is the case of Standard CSN Thermal protection of building There are some upgrades of existing legislation estimated - related to experience with EPC (Energy Management Law 406/2006 Coll., Decree No. 148/2007 Coll. Energy Performance in buildings. Tax regulations for energy efficient buildings does not exist in the CR Time schedule of implementation Generally, in case of residential buildings, EPC (in sense of EPBD) have to be used since 2010; public and nonresidential buildings have to use it since ; factories and producing buildings are excluded; related to: Energy Management Law 406/2006 Coll., Decree No. 148/2007 Coll., Building Code 183/2006 Coll., Decree No. 499/2006 Coll. Requirements on new and existing buildings are (will be) in force Residential building New building Existing building For sale For rent Non Residential building Issuance of energy performance certificates is mandatory since / will be mandatory Residential building Non Residential building New building

7 Energy certification in European countries 8 Existing building For sale For rent Public building Methodologies Article 3: Member States shall apply a methodology, at national or regional level, of calculation of the energy performance of buildings 3.1. New buildings Minimum requirements equal to reference building which is calculated from standardized values (i.e. U- value of components-based on CSN ; heating system-based on CSN EN ISO 13790; ventilation system based on minimal hygienic requirement (e.g. 0,5 volume per hour in apartments), cooling based on maximal indoor temperature in summertime (e.g. 26 o C in apartments), lighting (minimal standard illumination in lux per each building and room type)). In EPC-terminology it means that the building has to be classified with a letter C or better (A, B). The only difference between res and non-res buildings is in reference building Energy Performance value. These values are given by the Decree 148/2007 Coll. Energy Performance of Buildings for 8 basic types of buildings: family house, multi-family house, hotel and restaurant, office building, hospital, educational building, sport facility, shopping building. The asset rating calculation is based on a holistic model (iteration on hourly (for cooling), daily, monthly base); operational rating is not used Existing buildings The same requirements as for newly built buildings. The same EP Certificate is being used as well Energy certificates New building Calculation method has been described in 3.1., there are no differences in it. Asset rating only is being used. See Annex for example of EPC used in the Czech Republic. There is no difference in EPC between newly built buildings and reconstructions and no difference between classic calculated EPC and DEC Existing buildings Calculation method has been described in 3.1., there are no differences in it. Asset rating only is being used Public building Calculation method has been described in 3.1., there are no differences in it. Asset rating only is being used National software The National Calculation Tool had been introduced by expert team at Faculty of Civil Engineering of CTU in Prague in 2006 as a draft version for testing and a year after (11/2007) new version of this Tool has been used for evaluation of building in the EPBD meaning. The Tool is based on MS Excel platform and is free-of-charge. This tool base shall be used by commercial software companies during developing a commercial and more userfriendly tool.

Requirements Article 4: Member States shall take the necessary measures to ensure that minimum energy performance requirements for buildings are set, based on the methodology referred to in Article 3. Definition of Energy Performance an amount of consumed energy in case of existing buildings, an amount of energy calculated on a base of reference building ; energy for heating, ventilation, cooling, hot water heating, lighting and auxiliary energy for these systems are evaluated only; energy on a system border of a building is calculated, any factors are not used. End energy (delivered) is being evaluated. In real, energy consumption has to be calculated in each case because only invoiced total energy consumption is usually known (distinguished by energy bearer only gas, electricity, oil etc). Table: Requirements of the Czech Decree 148/2007 Coll. Energy Performance of Buildings - EP [kwh/m 2.year] Type of a building family house multi-family house hotel and restaurant office building hospital educational building sport facility shopping building Notice: Red line = Borderline value of Energy Performance. All new buildings and major renovated buildings, where at least 25% of building envelope shall be reconstructed, have to reach A, B or C. Other reference building values for other building types which are not described in the table have to be calculated on a base of standard pren (or newer). Calculation is based on minimum requirements of compulsory standards and regulations. Required (maximal) heat-transmittance coefficient (U-value) in W/m 2 K has to be fulfilled as well. The most important required values are summarized in following table. The most important required and recommended U-values (source: CSN Thermal Protection of Buildings) Description of construction Required U-value [W/(m 2.K)] Recommended Flat roof and slope roof under 45 o Ceiling above exterior Ceiling under uninsulated loft Wall (heated) 0,24 0,30 0,16 0,20 Wall (light = under 100 kg/m2) light 0,30 0,20 heavy 0,38 0,25 Floor on soil 0,45 0,30 Windows, doors (incl.frame) 1,70 1,20 Windows, doors (incl.frame) between heated and internal unheated area 3,50 2, New buildings Article 5: Member States shall take the necessary measures to ensure that new buildings meet the minimum energy performance require-ments referred to in Article 4. Requirements described in previous chapter 4. Requirements are valid for new buildings.

9 Energy certification in European countries Renewables, CHP, district heating/cooling Article 5: For new buildings with a total useful floor area over m2, Member States shall ensure that the technical, environmental and economic feasibility of alternative systems such as: decentralised energy supply systems based on renewable energy, CHP, district or block heating or cooling, if available, heat pumps, under certain conditions, is considered and is taken into account before construction starts. 100% implemented in the sense of Article 5. For new buildings with a total useful floor area over m2, Member States shall ensure that the technical, environmental and economic feasibility of alternative systems such as: decentralised energy supply systems based on renewable energy, CHP, district or block heating or cooling, if available, heat pumps. It has to be taken into account before construction starts. Data from Energy Audits (if available) can be used or simplified analysis made. Detailed analysis is not necessary in EPC (due to extreme increase of costs of EPC), it can be made as a part of Energy Audit afterwards Existing buildings Article 6: Member States shall take the necessary measures to ensure that when buildings with a total useful floor area over m2 undergo major renovation, their energy performance is upgraded in order to meet minimum requirements in so far as this is technically, functionally and economically feasible. Requirements described in previous chapter 4. Requirements are valid for existing buildings which shall be renovated on a major renovation level Definition major renovation In the Czech Republic, major renovation in a sense of Decree 148/2007 Coll. Energy Performance of Buildings means for buildings with more than 1000m 2 of floor area that (1) at least 25 % of a surface area of a building envelope shall be reconstructed or (2) a change of building services systems causes at least 25 % change of total energy consumption Energy certificates New building Existing building Public building Residential building Over 1000m 2 of floor area, technical, environmental and economical feasibility of alternative systems have to be assessed Non Residential building Over 1000m 2 of floor area, technical, environmental and economical feasibility of alternative systems have to be assessed EPC used as a DEC

10 Energy certification in European countries Energy performance certificates Article 7/1: Member States shall ensure that, when buildings are constructed, sold or rented out, an energy performance certificate is made available to the owner or by the owner to the prospective buyer or tenant, as the case might be General description Only one type of EPC exist in the CR. Only asset rating is used. The reference values are the same for both new and existing buildings, these values differs in dependence on type of a building (see Chapter 4. Requirements of this document). EPC has to be provided in case of building permit (new buildings and major renovated buildings) as a obligatory part of building permission documentation (based on the decree 499/2006 Coll.). For the only type of EPC (=DEC) see Annex Existing buildings There are no differences in EPC in case of existing buildings Public buildings Definition of public buildings Article 7/3 Member States shall take measures to ensure that for buildings with a total useful floor area over m2 occupied by public authorities and by institutions providing public services to a large number of persons and therefore frequently visited by these persons an energy certificate, not older than 10 years, is placed in a prominent place clearly visible to the public. Public buildings in a sense of decree 148/2007 Coll. Are schools; health care buildings; cultural buildings; shops; sport facilities; accommodation and public eating facilities; customs centres of water utilization, energetics, transport, telecommunications and public authorities. In all cases with at least 1000m 2 of useful floor area Additional aspects As a very good source of relevant data, Energy Audits (besed on Law 406/2000 Coll. Energy Management Act and decree 213/2001 Coll. Energy Audit) can be used. It makes EPC easier to make and cheaper. Nearly all public buildings have such an Audit, many other both private (especially commercial) and municipal buildings have it as well On site visit Energy Audits usually are made on a basis of on site visit. On site visits are just voluntary. 6. Independent experts Article 10 Member States shall ensure that the certification of buildings, the drafting of the accompanying recommendations and the inspection of boilers and air-conditioning systems are carried out in an independent manner by qualified and/or accredited experts, whether operating as sole traders or employed by public or private enterprise bodies 6.1. Training Training before the exam is voluntary, takes about 1,5 day. First, half-day part, is just theoretical (legislation, EPBD framework, goals of certification etc). A day part consists of real evaluation based on NKN-Tool (National Calculation Tool) with supervision of Tool-authors and experts. This training takes place at the Faculty of Civil Engineering in Prague with a support of Ministry of Industry and Trade, 6.2. Accreditation In the very first phase, only highly experienced Energy Auditors were accredited (without common examination) to the Certification. Other persons less experienced Energy Auditors and Authorised (by the Chamber of Authorised Engineers) Persons have to pass an exam. Nobody else can be accredited for the Certification. Basic topics for the

11 Energy certification in European countries 12 exam are described in decree 148/2007 Coll., the exam takes about a day. Ministry of Industry and Trade is responsible for examination and accreditation of experts as well Quality assurance Quality shall be controlled by State Energy Inspection (SEI). Sanctions are defined in Energy Management Law 406/2000 Coll., article 12a. SEI should do random controls of EPC and a common control of Building Permit Documentation (so SEI did for ages in case of previous Decree 291/2001 Coll.) Organisational aspects Legislation (decree 148/2007 Coll.), examination and accreditation of experts are tasks of Ministry of Industry and Trade. State Energy Inspection who should be a controlling state organisation is traditional organisation, not established for the purpose of EPC Number of experts available Nowadays, they are about 300 accredited experts available. In total there are about 300 Energy Auditors and about Authorised Persons, who could be accredited. This is a number of possible accredited Persons. In real, we can estimate about one third or fourth of them to be accredited = about 3000 Persons Transboundary certification 7. Data Collection 7.1. Availability and organisation of national data collection There is unfortunately no data collection or statistics of certified buildings nowadays, neither on national nor on regional level Access and use of the collected data 8. Experiences, evaluation, costs 8.1. General availability of experiences with EPBD implementation Process is in its beginning from 2007, so it is quite a short time to make clear evaluation. Meaning of many experts and public in the CR is, that Certification method is not only a way how to describe a building and its systems and energy performance, but some kind of protection against some designers, developer companies and construction companies as well. Nowadays, the approach of them in field of energy performance is very "informal" Existing studies, surveys and evaluations As the process of EPBD related evaluation is in the beginning, no studies, statistics or surveys are to disposal Number of energy performance certificates EPC for Construction permit will be compulsory since , but calculation based on EPC method are being done nowadays. Our estimation of completed EPC is: New buildings, residential buildings 600 New buildings, non-residential buildings 200 Existing buildings, residential buildings 500 Existing buildings, non-residential buildings 350 Public buildings 1000 Estimated for years Residential buildings Non-residential buildings Public buildings Effort and costs of energy performance assessment

12 Energy certification in European countries Time and costs There is no scale of tariffs and fees for energy certification, our rough estimation is: Non-residential buildings 1800 EUR 3 days Residential buildings 1500 EUR 2 days Public buildings 2000 EUR 3 days Average costs (roughly estimated market price) for a single family home and an apartment building with eight flats: Single family home 400 EUR 1 day Apartment with eight flats 1200 EUR 2 days Fixed prices are not possible in accordance to national legislation Subsidies Owners of Public buildings can get subsidy for chosen pilot projects of certification. 9. Acceptance of the energy performance certification Topic of phase 3 (July September 2008) 10. Plans for future development Revision of decree 148/2007 Coll. shall be made after experts get more experienced; estimated in 2009 or 2010; More persons shall be accredited, maximal capacity: 300 Energy Auditors and Authorised Persons; More buildings shall be evaluated, especially buildings under 1000m 2 of useful floor area; according to continuing of EPBD revisions.
