Zhenjiang energy efficiency experimental public building covers a
building area of 902.34m2, with the height of 15m, four-storey. By
the
Design
Standard for Energy Efficiency of Public Buildings, the
annual heating, ventilation, air conditioning, hot water supply,
lighting and electricity power should be reduced by 50% without
changing indoor environment parameters. The project studies the
thermal performance and energy efficiency method of the envelope,
compares the three air conditioning option and simulates the natural
ventilation. We also study the various lighting methods, select the
light source, provide the lighting control scheme and discuss the
feasibility of the application of solar energy for the public
buildings in Zhenjiang. We select the VRV air conditioning scheme
because of its high economic value and feasibility; prove the
advantage of atrium natural ventilation in the aspect of improving
interior air comfort and air conditioning energy efficiency;
arrange the exterior door and window, and select the light source,
lamps and lighting control to save 10% lighting energy consumption.
