Energy-Saving Design Research of Entrance Space for Commercial Building in Cold Region

All of public buildings, commercial building is a special type of energy consumption larger, especially the energy consumption of air conditioning. This paper illustrates entrance space of commercial building in cold region of China as the research project, studying its energy-saving design. Aiming at the problems existing in the present designs, this paper puts forward some targeted solution measures: adopt reasonable entry form, increase thermal damping space, expand the entrance area and make full use of solar energy. These measures can reduce the heat loss of the entrance space, improve thermal comfortableness, and achieve the goal of energy saving.
