节能改造已被广泛认为是老化住宅建筑的最佳解决方案。为了指导中国的此类实际项目，并从这些活动中实现能源、环境和经济领域的利益最大化，本文开发了一种在设计阶段的早期阶段协助决策者设计节能改造方案的方法，并通过案例研究来演示如何应用它。在此基础上，综合考虑所有有效、可行的节能措施，为主体建筑提出合适的节能改造方案，并准确评估其降低能耗、二氧化碳排放和成本的效果。研究结果表明，从减少能源消耗和二氧化碳排放的角度来看，我国现有住宅建筑的节能改造值得实施，但从经济角度来看，政府应对此类实际项目提供一定的补贴并提高电价。
Energy-efficient renovation had been accepted widely as the best solution for aging residential buildings. In order to guide such real projects in China and maximize the benefits in energy, environmental and economic fields from these activities, this article developed a methodology to assist decision-makers to design energy-efficient renovation plan in the early stage of design phase, and used a case study to demonstrate how to apply it. Following it, a suitable energy-efficient renovation plan, integrating all effective and available energy-saving measures, could be put forward for the subject building, and its effects on reduction of energy consumption, CO2emission and cost be evaluated accurately. The results showed that from the viewpoint of reducing energy consumption and CO2emission, energy-efficient renovation was worth being implemented to upgrade the existing residential buildings in China, but from the economic view, governments should provide certain subsidy for such real projects and increase electricity price.
