住宅建筑节能产品选用的成本-能效分析

住宅建筑节能作为建筑节能的重头戏，其意义和地位举足轻重。如何有效地选用同时满足节能要求和节省成本的产品已成为备受关注的问题。以典型住宅单元作为载体，分别对目前市场上常见的16种节能产品进行了成本-能效分析，并根据分析结果对这些产品的能效成本比进行了排名。这些产品的能效分析借助REM／Rate软件获得，成本价格结合全国定额水平和市场调查获得。结合开发商和业主所在地区的节能产品价格，本研究所提供的分析方法可用于优化节能产品的选用。

Cost-Efficiency Analysis for Selection of Energy Efficient Facilities in Residential Buildings

Residential buildings as a major part of building industry, its significance and status are vital in reducing energy consumption. How to effectively choose products and/or favilities which meets both energy-efficient and cost-effective requirements simultaneously has be- come a major concern. With a typical residential unit in certain area as a sample, cost-efficieucy analysis were carried out on 16 kinds of commonly available energy-saving products respectively and rank them according to the most beneficial for the least cost. Energy-simulation software REM/Rate was used to perform energy evaluations and derive the benefit of each product. Therefore, considering costs of energy-sav- ing products in a given geographic area, the analytical methods in this research can be used to guide selection of energy-efficient products.
