供暖成本分配（HCA）系统是监控设备和会计程序的组合，旨在允许集中供暖多户建筑的能源成本根据使用情况在各个公寓之间进行分配。对明尼苏达州实施HCA的九栋建筑的分析表明，平均节省了16%的天然气使用量，简单的回收期为1.4年。业主报告租户的反应可以接受，营业额或空置率没有长期增长。分配激励租户高效使用能源，有助于控制建筑业主的成本，并为转换为单独供暖系统提供替代方案。需要实施标准，以确保建筑效率得到维持，成本得到公平分配。美国和欧洲的经验表明，这些标准必须涉及:建筑能源规范、设备和安装、非计量用途的分配、披露和租赁教育，以及计量和计费。 引文:研讨会，ASHRAE交易，第95卷，pt。1989年，芝加哥

Heating cost allocation (HCA) systems are combinations of monitoring devices and accounting procedures designed to allow the energy costs in centrally heated multifamily buildings to be divided among the individual apartments on the basis of use. Analysis of nine Minnesota buildings in which HCA was implemented showed average savings of 16% of total gas use and simple paybacks of 1.4 years. Owners reported acceptable tenant reactions and no long,term increase in turnover or vacancy. Allocation motivates tenants to use energy efficiently, helps to contain building owners’ costs, and provides an alternative to conversion to individual heating systems. Implementation standards are needed to ensure that building efficiency is maintained and costs are allocated fairly. U.S. and European experience shows that these standards must address: building energy codes, equipment and installation, allocation of non-metered uses, disclosure and tenanteducation, and metereading and billing.
