【摘要】 我国二氧化碳的三大排放大户是工业、建筑和交通,其中,建筑领域能耗最高,已经超过工业成为社会第一能耗大户。在发展低碳经济的背景下,建筑节能势在必行。我国既有建筑量大面广,存在巨大的节能潜力,对节能改造进行能耗模拟分析和经济评价非常必要,可为既有建筑节能改造的决策和方案优选提供判断依据。开展本文研究具有重要的理论意义和现实需求。首先,结合国内外的节能减排背景和发展趋势,对建筑能耗、既有建筑节能改造研究与实践进行了较系统的研究阐述;其次,总结了我国建筑能耗的特点和既有建筑节能改造潜力与需求,提出了基于建筑能耗影响因素的节能改造技术;再次,提出了既有建筑节能改造技术经济评价模型,分为六个阶段:即建筑节能性能判断、节能改造需求分析和确立目标、技术选择与方案拟定、建筑能耗模拟、方案经济性评价、节能效果测算与后评价。并通过计算经济性评价指标,进行方案的优选。最后,选取堰河村银杏山庄进行案例研究,应用PBECA软件工具对四种节能改造方案进行能耗模拟,利用本文所构建的既有建筑节能改造经济评价模型进行节能方案效果评价,参考国家标准规范,同时以技术经济评价为主,在不同的互斥方案进行横向对比,最终选出最优方案,并提出了促进既有建筑节能改造的技术措施和实施建议。
【Abstract】 Among the three big sources of carbon emission of our country, industry, buildingand traffic, building energy consumption has been the biggest one over industry. It’simperative to push energy-saving and low carbon development under low carbon economy.There are large areas of existing buildings in China and the energy-saving potential isquite huge. Therefore it’s very necessary to conduct energy efficiency analysis andevaluation in order to provide basis for the decision-making and implementation ofenergy-saving reconstruction. The research of this paper has much theoretical significanceand practical needs.First, the paper systematically elaborates energy consumption and energy-savingreconstruction of existing building combined the background and trends of energyconservation at home and abroad. Then, the paper summarizes the building energyconsumption characteristics of China and energy-saving potential and demand of existingbuildings. Energy-saving technology is proposed based on influencing factors of buildingenergy consumption. Afterwards, the paper proposes the technical andeconomic evaluation of energy-saving reconstruction model, which is dividedinto six stages, including energy-saving performance judgment of building, analysis ofenergy-saving reconstruction potential and setting up targets, technology selection andprogramming, energy consumption simulation of building, economical evaluation ofprogram and post-evaluation by calculating the economic indicators, and then thepreferred program is selected.Finally, the paper conducts empirical study with the established model andmethodology. It selects the YinXing Villa in Yanhe village as the case, using the softwaretool such as PBECA to conduct energy simulation for four energy-saving reconstructionprograms, so as to provide energy-saving effect evaluation of energy-saving reconstructionprogram, refer to national standards and contrast mutually exclusive programs indifferent horizontal comparison, at last, the preferred program is selected, and technicalmeasures and implementation recommendations of energy efficiency of existing buildingsare proposed.
