IfcHvacDomain定义了供暖、通风和空调（HVAC）领域内互操作性所需的基本对象概念。它扩展了IfcSharedBldgServiceElements中定义的概念。
IfcHvacDomain架构的范围定义为：
①构成管道和管道分配系统的管段、配件和连接件，通常用于建筑设施，如空调、通风和排气系统；冷冻水、蒸汽和加热热水、饮用水、废水、天然气和液化石油气系统等。
②通常用于建筑服务系统的设备，如锅炉、冷水机组、风机和泵以及与这些部件相关的隔振装置。
③终端和流量控制装置，如通风口和格栅、可变风量调节器、阀门和阻尼器。
以下内容此时被视为超出了IfcHvacDomain架构的范围：
①电力生产、制造、制造等工业、事业单位专用设备。
②明确处理化学或生物制剂等有害物质的规定
③超出IfcBuildingControls域模式定义的这些设备的控制系统和排序系统
