Energy Saving Analyses on Envelope Thermal Properties in Hot Summer and Cold Winter Region

Abstract:

Residential buildings were selected as the research object in the seven typical cities of hotsummer and coldwinter region.The model of sixstorey residential building was set up.Firstly,the effect of thermal properties of enclosure each component on energy consumption of residential buildings was analyzed by energy consumption software VisualDOE 4.0.Enclosures include roof,window,sunshade and exterior wall,et,al.Secondly,comprehensive measures schemes of energy saving were designed by the orthogonal experiment.Then,the building energy consumption and energy efficiency rates of different enclosures combination schemes were compared and analyzed.Finally,the optimize combination scheme is determined,exceeding the goal of enclosures saving 25% of energy.Simulation results are accordant with the experimental results.It is fully verified the correctness of the simulation calculations.
