【摘要】：建筑耗能伴随着建筑总量的增加而成为我国能源消耗的大户,因而建筑节能工作在国内引起了广泛的关注。目前,我国既有建筑的节能改造工作陆续在各地开展,逐渐呈现出规模化、区域化、类别化推进趋势,但多集中在既有住宅建筑上,对建立既有公共建筑节能改造技术群的研究工作较少。陕西省横跨两大建筑气候区,既有建筑节能改造开展因气候差异、经济发展、政策支持等原因有着其特殊性和复杂性。商场建筑作为陕西省不同建筑气候区的既有公共建筑的代表,量大且能耗高。选择既有商场建筑进行节能改造,研究适合陕西省地区既有公共建筑节能改造分类、策略,对于推动陕西省既有建筑节能改造发展有着示范作用。本文以陕西省不同建筑气候区——寒冷A区的榆林市、寒冷B区的西安市以及夏热冬冷地区的汉中市三个地区的既有商场建筑作为研究对象,对这三个典型建筑气候区既有商场建筑进行实地调研、现场测试分析,更好地了解陕西省既有商场建筑能耗状况和室内热舒适度条件,找出存在问题,制定改造计划。根据改造内容,用DeST软件模拟各地能耗现状并模拟分析三地通用模型能耗现状及改造效果,建立陕西省不同建筑气候区既有商场节能改造技术群。其主要包括外围护结构热工性能改造、可再生能源节能技术改造、采暖空调设备节能改造以及建筑环境控制系统节能技术改造,对陕西省既有公共建筑节能改造工作提供一定的参考价值。
[Abstract]:Building energy consumption has become a major energy consumption in our country with the increase of building total energy consumption, so building energy efficiency has attracted extensive attention in China. At present, the energy-saving transformation of existing buildings in China has been carried out one after another in various places, gradually showing the trend of scale, regionalization and classification, but most of them are concentrated on existing residential buildings. The research work on the establishment of the existing public building energy-saving retrofit technology group is less. Shaanxi Province straddles two major building climate regions, and the existing building energy-saving transformation has its particularity and complexity due to climate difference, economic development, policy support and so on. As the representative of the existing public buildings in different climatic areas of Shaanxi Province, shopping malls are large in volume and high in energy consumption. In order to promote the development of the existing buildings in Shaanxi Province, the existing shopping malls are selected to carry out the energy-saving transformation, and the classification of the existing public buildings in Shaanxi Province is studied. In this paper, the existing shopping malls in Yulin City in Cold A area, Xi'an City in Cold B area and Hanzhong City in Hot Summer and Cold Winter regions in Shaanxi Province are taken as the object of study. The existing shopping malls in these three typical climatic areas are investigated on the spot, tested and analyzed on the spot to better understand the energy consumption and indoor thermal comfort conditions of the existing shopping malls in Shaanxi Province, to find out the existing problems, and to draw up the renovation plan. According to the reform contents, the energy consumption situation of all regions is simulated with DeST software, and the energy consumption situation and transformation effect of the general model of three places are simulated and analyzed, and the technology group of energy-saving transformation of existing shopping malls in different building climate areas in Shaanxi Province is established. It mainly includes the transformation of thermal performance of exterior protection structure, energy saving technology of renewable energy, energy saving of heating and air conditioning equipment and energy saving technology of building environment control system. It provides a certain reference value for the existing public building energy-saving renovation work in Shaanxi Province.
