基于热舒适性提升的寒地老旧住宅改造碳排控制机理及策略研究

In our country, the old residential buildings in the cold area are deteriorated, the function is far from modern residence’s, the thermal environment quality is low, and the energy saving problem is outstanding. It is urgent to improve the comfort of the physical environment and promote the construction of low carbon city. But at present the residential renovation limited to the building’s exterior envelope renovation. The method only pay attention to economic benefits. It is lack of awareness in the renovation process of how to improve the building thermal environment and thermal comfort. The feasibility research of energy-saving low carbon transformation strategy is insufficient. This project uses the method of investigation and numerical simulation combined with theoretical analysis, explore research of the carbon emission control mechanism and low carbon strategy about old residential renovation in cold areas. The main research is about the old residential building envelope, the end equipment of the transformation process: 1, The distribution of carbon emissions. 2, The reason of carbon emission impact and control mechanism. 3, The coupling relationship of low carbon transformation strategy and thermal comfort improvement. 4, The appropriate technology of low carbon transformation. Through the hierarchy relationship between the key technologies of thermal comfort improvement and multi-target to build the model of carbon emissions and low carbon transformation evaluation standard is innovative. It has practical significance to the energy consumption of the old residential renovation and carbon emissions database in northern heating area in our country. Do the strategic preparation for the effective implementation of energy-saving emission reduction and construction of low carbon society. Promoting old residential buildings low carbon transformation and quality improvement in north heating area in our country.

我国寒地城市老旧住宅建筑机能劣化、与现代住宅功能差距较大、热环境质量低下、节能问题突出，提高物理环境舒适性，促进城市低碳建设的研究迫在眉睫。目前节能改造多限于外围护结构改造，改造方法只注重经济效益，对如何改善建筑热环境和提升热舒适性认知不够，对低碳策略的可行性研究不足。本项目拟采用实测调研、数值模拟和理论分析相结合的方法，探索寒地老旧住宅改造过程的碳排放控制机理及低碳策略研究。重点探索老旧住宅围护结构、末端设备改造中的关键科学问题：1、碳排放量分布规律；2、碳排放量影响要因和控制机理；3、低碳改造策略与提升热舒适性的耦合关系；4、低碳改造适宜技术。通过提升热舒适性的关键技术和多目标多类型的层级关系，建立碳排放分布模型和低碳改造策略具有创新性，对推动寒地老旧住宅改造的能耗和碳排放数据库建设具有现实意义。为推进寒地老旧住宅的低碳改造与品质提升，有效实现节能减排、构筑低碳社会做好战略准备。
