Research On Energy-saving Design Of Public Building Envelope System - Severe Cold Area

Winter heating is the main characteristic of energy consumption in China ’s severe cold regions,and the thermal performance of the enclosure structure is the factor that must be considered in building energy conservation.Due to the diversity of facade forms and plane functions of public buildings,it is obviously impossible to meet the requirements of engineering practice to judge whether the building is energy-saving by using only specified indexes,and the research depth and breadth of the weighing and judging design method in China are limited at present,Previously,few architects systematically combed the theory of balance judgment from an architectural perspective,and few explored its significance and effectiveness in the new version of《 the public building energy efficiency design standard》GB50189-2015,Therefore,combining with the experience of many years of architectural design in the cold area,the author makes a detailed analysis of the origin,practical significance and potential social benefits of the trade-off judgment theory from the architectural point of view,and has certain practicability and universality,and on this basis,creatively puts forward a new application concept of weighing and judging,in order to provide a certain theoretical follow-up and ideological inspiration for building energy-saving design in cold areas in the future.In this process,the author also carried on the operation demonstration to the domestic building design field commonly used computing software,through the comparison and analysis with foreign similar software,pointed out the direction of China’s energy-saving design software improvement,put forward opinions and suggestions,hoping to make due contributions to the cause of building energy conservation.
