本欧洲标准规定了一套假设，要求和验证测试，用于计算建筑物中的房间的空间采暖和冷却的年度能源需求的程序，其中计算时间为1小时或更短。 本欧洲标准没有规定任何具体的数值技术来计算室内加热或冷却需求以及室内温度。 本欧洲标准的目的是验证以下计算方法: ï¾评估建筑物每个房间的能量表现; ï¾提供能量数据作为系统性能分析（加热，制冷，通风，照明，家用热水等）的界面。 验证程序用于基于瞬态显热平衡模型来检查空间加热和冷却的能量需求，同时考虑: ï,¾外表面热平衡; ï，通过建筑物信封的传导; ²外部和内部结构的热容量; ï,¾内表面热平衡; ï,¾空气热平衡; ï¾热平衡溶液法。 所有其他方面都由规定的边界条件或输入数据给出，不是模型验证的一部分。假设，对于所有的人

This European Standard specifies a set of assumptions, requirements and validation tests for procedures used for the calculation of the annual energy needs for space heating and cooling of a room in a building where the calculations are done with a time step of one hour or less. This European Standard does not impose any specific numerical technique for the calculation of the room heating or cooling need and the internal temperatures of a room. The purpose of this European Standard is to validate calculation methods used to:  assess the energy performance of each room of a building;  provide energy data to be used as interface with system performance analysis (heating, cooling, ventilating, lighting, domestic hot water etc). The validation procedure is used to check the energy need for space heating and cooling based on a transient sensible heat balance model, taking into account:  the external surface heat balance;  the conduction through the building envelope;  the thermal capacities of external and internal structures;  the internal surface heat balance;  the air heat balance;  the heat balance solution method. All other aspects are given either by prescribed boundary conditions or by input data and are not part of the model validation. It is assumed, that for all these other matters e.g. embedded heating and cooling systems, prescriptive models have to be used according to existing European Standards. The system performance analysis and moisture balance are not within the scope of this European Standard.
