Evaluation method and system for energy efficiency performance of sun-shading product for building and storage medium

Abstract

The invention relates to an evaluation method and system for energy efficiency performance of a sun-shading product for a building, and a storage medium. The method comprises the steps: building a sunshade product model and a typical building model; then, based on data of the influence of the human behaviors on the use of a sun-shading product, determining a sun-shading product use time table; thirdly, based on the sun-shading product model, the sun-shading product use time table and the typical meteorological year data of an area where the sun-shading product is located, calculating the air conditioner energy consumption of using the sun-shading product in a typical building model; obtaining annual energy efficiency performance indexes of the sun-shading product according to the air-conditioning energy consumption of the sun-shading product in combination with the air-conditioning energy consumption when no sun shading exists and the air-conditioning energy consumption when a heat insulation window is arranged; and finally, carrying out grading evaluation on the sun-shading product based on an annual energy efficiency performance index. The annual energy efficiency performance evaluation index provided by the invention is a dimensionless index, is irrelevant to the building type, the building area, the window size and the like, and can better reflect the energy-saving effect of a sun-shading product compared with the energy-saving amount.

Description

technical field [0001] The invention relates to the fields of building technology and building energy conservation, in particular to an evaluation method for the energy efficiency performance of building sunshade products. Background technique [0002] With the implementation of "Technical Standards for Nearly Zero Energy Buildings" (GB / T51350-2019), the country and the government have paid more and more attention to building energy conservation. The energy-saving indicators of building components will be further improved, and the demand for high-efficiency and energy-saving building products will also continue to rise. As the weak link of thermal insulation in the building envelope, building exterior windows are usually equipped with sunshade products to block part of the radiant heat entering the room, thereby reducing air-conditioning energy consumption and improving the lighting environment. [0003] In the current standards, the "Design Standards for Energy Conservation...
