Research on the Impact Factors of Near Zero Carbon Small Office Buildings in Cold Regions during the Scheme Design Phase
This study aims to achieve near-zero carbon emissions in building design by investigating key design factors and parameter control for small office buildings in extremely cold regions.Using the near-zero carbon demonstration project at Shenyang Jianzhu University as a case study,Tianzheng software simulates the effects of factors such as building form,layout,orientation,atrium ratio,window-to-wall ratio,and photovoltaic roof angle on carbon emissions.The Pearson correlation coefficient method identifies optimal parameters.Simulations indicate that a compact mixed-use office layout is optimal,with an orientation of 0° to 30°,a form factor of 0.26 to 0.3,an atrium ratio of 5∶3 to 2∶1,a window-to-wall ratio of 0.3 to 0.4,and a photovoltaic roof angle of 10° to 25°.The factors are ranked by importance:form factor,photovoltaic roof angle,window-to-wall ratio,atrium ratio,building orientation,and layout.The target building achieved a carbon emissions reduction of 2 177 039.72 kg,or 83%,compared to the baseline model.This study demonstrates that thoughtful design and parameter control can effectively reduce carbon emissions and meet near-zero carbon goals.
