Energy Conservation and Consumption Reduction in Residential Quarters: Taking Cuihu Garden Residential District in Pingxiang City as an Example

Abstract

This paper uses Auto-Revit for an energy assessment of Cuihu Garden Residential District located in Anyuan District, Pingxiang City, Jiangxi Province. Comparative analysis of building energy consumption before and after energy-saving renovation. Through simulation analysis, it can be concluded that replacing LED light sources, enhancing natural ventilation efficiency, and increasing green roof construction can effectively reduce building energy consumption. This article draws the following conclusions: Firstly, by replacing the LED light source, the energy of the residents in the community can be reduced by 65.2%; secondly, the combination of mechanical ventilation and natural shaft ventilation can reduce 73kWh of electricity in ten hours; finally, the green roof energy effectively alleviate temperature changes on the surface of the building, and indirectly reduce the power consumption of heating and air conditioning in the building. The research results can serve as a reference for the improvement of building energy efficiency in cities with subtropical monsoon climate regions represented by Pingxiang City. The direction of energy-saving improvement can be extended to inland small cities in the country and the world.
