The main supported activity is the highest use of primary forms of energy in combined heat & power production.

The CHP development is expected and introduction of specific frame into the energy sector.

Legislative measure is a part of the national implementation of Directive 2004/8/EC.

Impact of Measure

An interest in DH is proclaimed, however CHP installations are no way prescribed.

Effectiveness of the measure

The measure can be considered as explicitly effective.

Primary energy savings are required at the level of 10% (in other case the production is not recognised as effective and the generator does not get the corresponding contribution for CHP.

The energy sector is with a high share based on a cheep brown coal. For these reasons it is difficult to promote CHP in smaller and middle plants, because such plants use exclusively the more expensive natural gas.

The temporary legislative measure complies with local market conditions and there is no effort to make some amendments.

An adherence to the act is under a control of the State Energy Inspection (cf. Act 458/2000 Coll./Energy Act). The controlling and registration of electricity producers in CHP is also provided by ERO. Licences for CHP plants operation are issued by the Ministry of Trade and Industry.

Quotations from the measure

Requirements for buildings energy demand

• (1) Requirements for buildings energy demand under §6 section 1 of the Act have been met on the condition that the energy demand of the assessed building determined in compliance with § 5 is lower than the energy demand of a reference building at maintaining general technical requirements for construction works. Details of the assessment towards the building energy demand requirements completion are listed in Appendix 1 to the Directive.
• (2) Energy demand of a reference building is an overall annually delivered energy indicated in GJ to be determined by a balance assessment of reference building under § 5. Appendix 2 to the Directive gives details about the calculations and the required input data for buildings energy demand assessment. Providing that a finished building is adjusted, and then the calculation of the overall required supplied energy in GJ needs the input data only for the concerned systems or elements of the buildings, the remaining input is the same as that of the assessed building.
• (3) When making a balance assessment, the same calculation method is used to determine the reference building energy demand, as that used in the determination of energy demand of the assessed building.
• (4) Failing to complete the requirements of section 1, technically and economically suitable measures are determined for the assessed building to reduce the energy demand to the required level. A comparison of the delivered energy to cover individual needs together with partial reference values is used for the design of the required measures.
• (5) The procedure to assess technical and economical feasibility of alternative energy supplies systems for heating, hot water and cooling under § 6a section 4 of the Act at new buildings of over 1000 m2 overall floor area is adjusted by Appendix N.3 to the Directive.
• (6) Energy demand of a residential unit or an internal zone of a building made for a separate utilization is proved by the completion of the requirements under section 1 for the whole building.

Other parts of Directive 148/2007 Sb. deal with the following issues (names of individual sections):

Directive 193/2007 Sb. – heat energy distribution and internal heat and cool distributions

directive

MTI

In force

Quotations from the measure

The Directive stipulates the details of the energy utilization effectiveness at heat energy distribution and internal distribution of heating and cooling energy.

The Directive stipulates the effectiveness of energy use in newly established heat energy distribution facilities and for the internal distribution of heating and cooling energy, and for the equipment of the facilities with heat insulation, regulation and control at the following devices:

a) steam, hot water and warm-water and cool distribution networks including their connections except of cooling water from energy and technology processes, that draws the heat energy off to the surrounding environment,

b) transfer of exchanger stations,

c) internal heat, cool and hot water energy distribution equipment in buildings (hereinafter “the internal distribution”)

The Directive further stipulates the method of heat loss determination in heat energy distribution facilities and in internal heat energy, cool and hot water distribution.

§ 2 The effectiveness of energy use at heat energy distribution

(1) The heat network is dimensioned in the way enabling a maximum heat energy transfer on an annual basis.

Heat network is dimensioned in a way providing for the maximum effectiveness of annual heat transfer. In the case that the optimization calculation respecting effective energy savings shows a suitability of an independent pipeline for off-peak heating season, then the pipeline is dimensioned according to the specific pressure loss.
(2) Energy use effectiveness in terms of its transport and heat loss is determined according to the template indicated in Appendix N. 1 to this Directive.

(3) When designing and reconstructing the existing heating networks, a solution is used with a minimum energy demand valuein terms of heat energy ηc and a maximum effectiveness value in terms of heat loss ηz. Minimum values, or maximum values may not ne maintained on the condition that a more suitable solution exists based on an optimization calculation while respecting effective energy savings. Circulation pump is not over dimensioned and is designed within its maximum energy effectiveness.

(4) Energy effectiveness in terms of heat losses in operational conditions is assessed once a year.

§ 3 Heat carrying medium and its parameters in heat distribution system

(1) Hot water up to 90°C or up to 115°C is used as a heating medium for heating and hot water preparation wherever feasible. Hot water of over 115°C is used for extensive heating networks designed to supply large residential districts, municipalities and distant consumers. Steam as a heat carrying medium is used whenever it is justifiable in terms of heat and technical conditions and by the optimization calculation, especially for technology purposes.
(2) Calculation temperature in the return line is lower or equal to 70°C. Temperature of over 70°C must be justified by the optimization calculation due to the heat accumulation in the network. The calculation must respect effective energy savings.

Purpose of the measure

The Directive relates to the heat distribution facilities and to internal heat energy and cool distribution serving heat energy supply to residential objects or to joint residential objects, for technical purposes and for non-residential areas.

Although the Directive refers to the integration of the relevant part of the Directive 2002/91/ES, it is linked to the latter only indirectly.

Quotations from the measure

§ 1 Subject of the adjustment

The Directive processes the relevant regulation by the European Union and stipulates the following:

a) the method of the inspection and assessment of the air conditioning systems inspection results,

b) the scope of testing of persons responsible for the inspection under letter a).

§ 2 Regular inspection of air conditioning systems:

(1) Regular inspection of an air conditioning system comprises the assessment of the air conditioning system effectiveness and its performance compared with the requirements for cooling of the building. The result of a regular air conditioning system inspection is a report containing the findings and the recommendations and assistance regarding possible improvement or replacement of the system and alternative solutions.

(2) Air conditioning systems inspection comprises the following:

a) identification of the air conditioning system in the scope under Appendix 1 to the Directive,

b) assessment of the documentation from the point of view of its completeness, relevance and maintenance

Purpose of the measure

The aim of regular air conditioning systems inspection is to reduce the consumption of energy and to limit CO2 emissions. The checkup should include the assessment of the air conditioning system effectiveness and the size of the equipment in comparison with the requirements for the building cooling.

Legislation measures are an integral part of the EU Directive N. 2002/91/EC implementation

Impact of the Measure

Effectiveness of the measure

Providing that the inspection is too simplified, it becomes a useless bureaucratic act, which is likely to happen. On the other hand, a detailed solution often lacks sufficient means, time and sufficient number of experts.

We do not have enough practical outcomes that might be used as a solid background for the assessment of the impact of the Directive.

(1) An energy audit shall be carried out by an energy auditor. An energy audit shall be elaborated with the use of energy-efficient materials and processes, objectively and truthfully. An energy audit carried out to an extent specified in an implementation regulation 6f) shall be completed with a written report that shall contain:

a) An assessment of the present level of the assessed energy facility and buildings;

b) The overall level of energy savings achieved, including the input and output information and calculation methods used;

c) A proposal of the selected variant recommended for the achievement of energy savings, including financial reasons.

(2) If an energy facility and a building have undergone a mandatory energy audit, or if a state subsidy has been used in the elaboration of the audit, the owner of the facility or building and the energy auditor shall provide, upon request, a copy of the energy audit to the Ministry, the State Energy Inspectorate, the region, and the municipality with local jurisdiction over the place in which the energy facility and building under review are located; this copy may be provided in electronic form.

(3) The obligation to subject an energy facility or a building to an energy audit shall be binding upon the following persons having ownership or another right of use:

a) Every natural or legal person applying for a subsidy in the Programme, if the installed output of the energy source exceeds 200 kW;

b) Organisational components of the State, organisational components of the regions and municipalities, of the City of Prague, and organisations subsidised by public funds, with aggregate annual energy consumption higher than the value set by an implementation regulation;

c) Natural or legal persons, except for organisations subsidised by public funds, with aggregate annual energy consumption higher than the value set by an implementation regulation.

(4) Organisational components of the State, organisational components of the regions and municipalities, and organisations subsidised by public funds, shall comply with the measures and deadlines set in a decision of the State Energy Inspectorate. 2)

(5) An energy audit shall not be performed if the existing technological facilities for the production of electricity and heat, transmission of electricity, distribution of electricity, and distribution of heat, comply with the energy efficiency requirements set by a special legal regulation.

(6) An energy audit shall not be performed for existing buildings whose measurable heat consumption in heating complies with the requirements set by a special legal regulation, and for buildings containing interior technological sources of heat, to the extent prescribed by a special legal regulation.

The Purpose of the measure

The above mentioned part of the Act aims to solve energy savings in energy management of energy producers and in buildings with the purpose to increase energy fficiency of energy plants and to decrease heat losses in buildings. The target group is installationsand buildings in the state ownership, regions and municipalities. This item is more detailed solved by the decree of Ministry of Trade and Industry no. 213/2001 Coll. And its amendment no. 425/2004 Coll..

Legislative measure solves the item covered by the Directive no. 2006/32/EC.

Impact of Measure

This legislative measure has been successfully implemented. All the larger DH systems have undergone the energy audits.

All the grant applications of grant programmes have to be provided with energy audit and the realised measures have to comply with the outputs (recommendations) of the energy audit.

Effectiveness of the measure

This legislative measure is effective.

§ 78 Metering

(1) The heat energy generation licence holder and the heat energy distribution licence holder shall provide measurement, interpret readings, and charge customers for heat energy supply in accordance with the actual parameters of the heat transfer medium and the readings obtained from its own metering devices, which shall be installed, connected and maintained by such a licence holder at its own cost. The licence holder shall also regularly check the correctness of the readings in compliance with a special legal regulation.12) The buyer shall be entitled to have the correctness of the reading of measured values verified on the input or output of the house substation.

(2) If the buyer has any doubt as to the correctness of the readings or finds a defect on the metering device, then the buyer shall be entitled to have the device tested. Upon a written request received from the buyer, the licence holder shall check the metering device within 30 days and replace it if a defect is found. The buyer shall provide assistance as needed for the replacement of the metering device. If the metering device is defective, then the costs of the testing and replacement of the device shall be borne by the licence holder. In the absence of any defect, such costs shall be borne by the buyer.

(3) Any handling of the metering device without the consent of its owner shall be prohibited.

(4) The licence holder shall be entitled to install the metering device, secure it against tampering, and carry out regular readings, and the buyer shall allow the licence holder to do so. If the buyer finds any defect on the metering device or on its protection against tampering, the buyer shall immediately notify the supplier of such a finding.

(5) The meter readings determined by the supplier, together with the prices at the site of metering, shall constitute the heat energy costs, which shall be allocated among the end users, i.e. the users of residential and non-residential premises.

(6) At the hot service water jointly prepared for several points, the licence holder ensures, since September 1st 2011, in each supply point measuring of delivered amount of hot water for the proposals of relative allocation of thermal energy costs, for its preparation and distribution to individual points along the § 76 subpar. 3 e). If an agreement on a way of costs allocation on individual points is reached among all consumers connected to the house substation and the supplier, the obligation of metering does not arise.

(7) If hot service water is jointly prepared for several buyers, metering installed by the buyers cannot be used for the assessment of heat energy supplied.

The Purpose of the measure

To objectify the energy flow, specify supplier – buyer relations.

Impact of Measure

The legislative measure influenced all the DH systems, especially as to the costs dealing with heat meters installations. At present time there is under discussion a new obligation to measure also heat in hot service water distributed by 4-pipes system at each buyer. In contrary to the present practice, when heat is exactly measured on the input and relatively measured on the output at each buyer, our legislation requires installation of other meters on inputs into each subject. This is very costly and does not ensure any effects.

Effectiveness of the measure

The legislative measure is effective, however the national legislation requires other and other metering to avoid often commercial disputes among supplier and buyer.
