EN 15316-4-6:2007 (E) 3 Foreword This document (EN 15316-4-6:2007) has been prepared by Technical Committee CEN/TC 228 “Heating systems in buildings”, the secretariat of which is held by DS. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2008, and conflicting national standards shall be withdrawn at the latest by January 2008. This document has been prepared under a mandate given to CEN by the European Commission and the European Free Trade Association (Mandate M/343), and supports essential requirements of EU Directive 2002/91/EC on the energy performance of buildings (EPBD). It forms part of a series of standards aimed at European harmonisation of the methodology for calculation of the energy performance of buildings. An overview of the whole set of standards is given in prCEN/TR 15615. The subjects covered by CEN/TC 228 are the following: design of heating systems (water based, electrical etc.); installation of heating systems; commissioning of heating systems; instructions for operation, maintenance and use of heating systems; methods for calculation of the design heat loss and heat loads; methods for calculation of the energy performance of heating systems. Heating systems also include the effect of attached systems such as hot water production systems. All these standards are systems standards, i.e. they are based on requirements addressed to the system as a whole and not dealing with requirements to the products within the system.
Where possible, reference is made to other European or International Standards, a.o. product standards. However, use of products complying with relevant product standards is no guarantee of compliance with the system requirements. The requirements are mainly expressed as functional requirements, i.e. requirements dealing with the function of the system and not specifying shape, material, dimensions or the like.
The guidelines describe ways to meet the requirements, but other ways to fulfil the functional requirements might be used if fulfilment can be proved. Heating systems differ among the member countries due to climate, traditions and national regulations. In some cases requirements are given as classes so national or individual needs may be accommodated. In cases where the standards contradict with national regulations, the latter should be followed.

EN 15316-4-6:2007 (E) 4 Part 2-1: Space heating emission systems Part 2-3: Space heating distribution systems Part 3-1: Domestic hot water systems, characterisation of needs (tapping requirements) Part 3-2: Domestic hot water systems, distribution Part 3-3: Domestic hot water systems, generation Part 4-1: Space heating generation systems, combustion systems (boilers) Part 4-2: Space heating generation systems, heat pump systems Part 4-3: Heat generation systems, thermal solar systems Part 4-4: Heat generation systems, building-integrated cogeneration systems Part 4-5: Space heating generation systems, the performance and quality of district heating and large volume systems Part 4-6: Heat generation systems, photovoltaic systems Part 4-7: Space heating generation systems, biomass combustion systems According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.
EN 15316-4-6:2007 (E) 5 Introduction This European Standard constitutes the specific part related to building integrated photovoltaic systems, of the set of EN 15316 standards on methods for calculation of system energy requirements and system efficiencies of space heating systems and domestic hot water systems in buildings. This European Standard presents a method for calculation of the electricity production of building integrated photovoltaic systems. The calculation is based on the performance characteristics of the products given in product standards and on other characteristics required to evaluate the performance of the products as included in the system. The user needs to refer to other European Standards or to national documents for input data and detailed calculation procedures not provided by this European Standard. Only the calculation method and the accompanying input parameters are normative. All values required to parameter the calculation method should be given in a national annex, containing appropriate national values corresponding to the tables given in Annex B.

Primary energy savings and CO2 savings, which can be achieved by photovoltaic systems compared to other systems, are calculated according to prEN 15603. Standards linked to photovoltaic systems are listed in Annex A. 2 Normative references The following referenced documents are indispensable for the application of this document.

EN 15316-4-6:2007 (E) 7 3.3 net power production total power produced by the photovoltaic panel minus all auxiliary energy consumption inside the sub-system boundaries 3.4 peak power electrical power of a photovoltaic system with a given surface and for a solar irradiance of 1 kW/m2 on this surface (at 25 °C) 3.5 recoverable system thermal loss part of a system thermal loss which can be recovered to lower either the energy need for heating or cooling or the energy use of the heating or cooling system 3.6 recovered loss part of the recoverable losses which are recovered
to lower the energy requirements 3.7 renewable energy produced on the building site energy produced by technical building systems directly connected to the building using renewable energy sources 3.8 renewable energy energy from a source that is not depleted by extraction, such as solar energy (thermal and photovoltaic), wind, water power, renewed biomass NOTE
In ISO 13602-1, renewable resource is defined as "natural resource for which the ratio of the creation of the natural resource to the output of that resource from nature to the technosphere is equal to or greater than one". 3.9 solar irradiance power density of radiant incident on a surface, i.e. the quotient of the radiant flux incident on the surface and the area of that surface, or the rate at which radiant energy is incident
