Research on Energy-Saving Design of Office Building Forms in Cold C-Region Based on Daylighting and Thermal Performance

Large office buildings in severe cold regions have high energy consumption and great energy-saving potential. It is of typical and practical significance to study the law of building form energy-saving design. From the perspective of day-lighting and thermal performance, the paper proposed the influence of building form parameters on energy consumption for high-rise office buildings in severe cold C-rigion by using computer simulation method and orthogonal test method.The results showed that:1)the difference of light climate could not be the dominant factor causing the difference of building energy consumption under the same thermal region;2)plane volume,floor height and window-wall ratio always had a significant impact on the building energy consumption;3)in general, the improvement of building envelope performance would reduce the sensitivity of form design parameters to energy consumption;4)the optimal parameter combination and the worst parameter combination would not change because of the difference of light climate and building envelope performance.The research conclusions could provide a reference for the primary stage of architectural design from the perspective of energy saving.
