Dimensioning;  Part 4: Installation;  Part 5: Heating and cooling surfaces embedded in floors, ceilings and walls — Determination of the thermal output. The main change with respect to EN 1264-1:1997 consists in the expansion of the scope over floor heating, now additionally includes ceiling and wall heating as well as cooling surfaces in floors, ceilings and walls. 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, Croatia, 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 the United Kingdom.

NOTE In the case of floor heating and cooling systems, as a rule the thermal resistance R,ins is provided by the insulation layers which are integral parts of the system; on this topic, national rules shall be consulted. In the case of wall and ceiling heating and cooling systems, the thermal resistance R,ins may be determined taking into account the effective thermal resistance of the building structure. 3.1.8 interior walls partitions of rooms within dwellings or similar used room groups NOTE Wall heating and cooling systems embedded in interior walls, are constructed with or without insulation, depending on their use. 3.2 Supplementary heating equipment Additional heating facility, e. g. convectors, radiators with the additional required thermal output and possibly with its own control equipment 3.3 Parameters of design 3.3.1 standard heat load in a floor heated room QN,f rate of heat loss from the building to the outside and to neighbouring rooms under standardized conditions, depending on the regional climatic data, the location, its use and the thermal properties of the building NOTE When calculating the standard heat load, the thermal output from the embedded heating systems in the neighbouring room is not taken into account.
