length measured on the exterior of a building 3.22 heated space room or enclosure which for the purposes of a calculation is assumed to be heated to a given set-point temperature or set point temperatures

enclose conditioned spaces through which thermal energy is transferred to or from the external environment or to or from unconditioned spaces NOTE 1 Thermal envelope area depends on whether internal, overall internal or external dimensions are being used. NOTE 2 The respective areas of the building envelope may be weighted with a (nationally fixed) reduction factor in case of e.g. unheated adjacent spaces and ground floors. 3.28 energy carrier substance or phenomenon that can be used to produce mechanical work or heat or to operate chemical or physical processes [ISO 13600:1997] NOTE The energy content of fuels is given by their gross calorific value. 3.29 energy need for heating or cooling heat to be delivered to or extracted from a conditioned space by a heating or cooling system to maintain the intended temperature conditions during a given period of time
2) Directive 2002/91/EC of the European Parliament and of the Council of 16 December 2002 on the energy performance of buildings

For active solar and wind energy systems the incident solar radiation on solar panels or on solar collectors or the kinetic energy of wind is not part of the energy balance of the building. It is decided at national level whether or not renewable energy produced on site is part of the delivered energy. NOTE 2 Delivered energy can be calculated for defined energy uses or it can be measured. 3.31 exported energy energy, expressed per energy carrier, delivered by the technical building systems through the system boundary and used outside the system boundary NOTE 1 It can be specified by generation types (e.g. CHP, photovoltaic) in order to apply different weighting factors. NOTE 2 Exported energy can be calculated or it can be measured. 3.32 net delivered energy delivered energy minus exported energy, both expressed per energy carrier NOTE 1 A balance of the delivered and exported energy per energy carrier can be performed only if the same primary energy factors and/or CO2 coefficients apply to the delivered and exported amounts of that energy carrier. NOTE 2 The term "net" can also be applied to quantities derived from net delivered energy, e.g. primary energy or CO2 emissions. 3.33 primary energy energy that has not been subjected to any conversion or transformation process NOTE 1 Primary energy includes non-renewable energy and renewable energy. If both are taken into account it can be called total primary energy. NOTE 2 For a building, it is the energy used to produce the energy delivered to the building. It is calculated from the delivered and exported amounts of energy carriers, using conversion factors.

* The unit depends on the indicator chosen. See Clause 5. Table 2 — Subscripts r required by regulation C conditioned s building stock e envelope
5 Energy performance indicators 5.1 Indicators The energy performance of a building is represented by an overall indicator EP that is the weighted algebraic sum of the delivered and exported energy per energy carrier determined according to Clause 5 of prEN 15603, normalized according to 5.3. EP may represent: a) primary energy (Ep); b) CO2 emissions (mCO2); c) net delivered energy weighted by any other parameter defined by national energy policy (e.g. delivered energy, or cost). This overall indicator EP may be complemented by other indicators, for example thermal performance of the building envelope. 5.2 Indicator basis The indicators shall be based on one of the two types of ratings defined in prEN 15603:  standard energy rating;  measured energy rating. The standard energy rating can be calculated either for planned buildings or for actual buildings. If the indicator is based on a standard energy rating it is called standard energy indicator. If the indicator is based on a measured energy rating it is called measured energy indicator.

Usually the choice is the same as for the calculation of the transmission heat transfer (see prEN ISO 13789:2005); in addition, there is a direct correlation with input parameters that are related to the conditioned area (e.g. conventional hot water demand, minimum ventilation, lighting). NOTE 3 An estimate of AC can be obtained from the conditioned volume and mean floor height. 6 Expression of energy requirements 6.1 Ways of expressing the requirements Two main types of requirements are defined: a) overall energy performance requirement in accordance with 6.2; b) specific requirements based on: 1) energy use for specific building services (e.g. heating, domestic hot water, cooling, lighting, ventilation); 2) energy need for heating, domestic hot water and cooling; 3) characteristics of the building itself or of its technical building systems considered as a whole (e.g. heat transfer coefficient of the building envelope, heating, domestic hot water or cooling system efficiency); 4) characteristics of the building envelope or technical building systems components (e.g. thermal transmittance of walls, efficiency of boilers, insulation of heating and hot water pipes, lighting power density (W/m2), specific fan power). Information on possible specific requirements is given in Annex D. An overall indicator may be combined with specific requirements. NOTE Reasons for doing that include: 1) to avoid too large tradeoffs between the performance of the building envelope and the performance of the technical systems; 2) to avoid technical health or discomfort risks; 3) to prevent components with low performance to be put on the market. See Bibliography [1] for more background information on the advantages and disadvantages of additional requirements. The indicators used may be different for:  a new building;  renovation of an existing building;  an extension to an existing building;  different types of buildings.

rEPEP≤ (1) where EP is the overall energy performance indicator; EPr is the limit value which defines the requirement. When a given building has different functions k (e.g. education + sport) with different requirements EPr,k, procedures shall be defined to weight the different requirements. Unless other procedures are specified, the following procedure applies: c1,r,crAEPAEPnkkk∑=⋅= (2) where k represents the functions: k = 1, 2, ., n. The conditioned area of a space that is commonly used for more than one building function shall be proportionally divided over the conditioned areas of these building functions.
