Residential building energy-saving effect evaluation simple method

Abstract

The present invention discloses a residential building energy-saving effect evaluation simple method and belongs to the energy-saving building evaluation field. The residential building energy-saving effect evaluation simple method includes the following steps that: S1, indoor temperature is adopted as a constant, S2, cooling and heating loads in a house are calculated; S3, data about fresh air volume, cold and hot water quantity and electric load under the temperature and humidity conditions of indoor design are calculated; S4, an equivalent window opening rate is calculated through a building envelope structure; S5, energy consumption calculation is performed for the performance parameters of the envelope structure according to a first-order equation; and S6, display is performed in a list form and a data model form based on the above calculation results. The method of the invention has the advantages of rigorous principles, high feasibility, high practicability and convenient calculation. According to the method, evaluation indexes and standards can be adjusted flexibly; the realization of computerization can be facilitated; the matter-element models of the evaluation indexes can be built so as to describe the characteristics of visible objects; and quantitative numerical values are adopted to expresses evaluation results, and therefore, the energy saving level of a building can be reflected intuitively.

Description

technical field [0001] The invention relates to the technical field of energy-saving building evaluation, in particular to a simple method for evaluating the energy-saving effect of residential buildings. Background technique [0002] There are many factors that affect building energy consumption. Differences in different climate conditions in different regions, differences in the living standards and energy patterns of building users, and changes in the thermal performance of the building envelope itself will all lead to changes in building energy consumption. Can it really reflect the energy consumption level of the building and truly evaluate the effectiveness of the energy-saving technology of the building? [0003] At present, the method of evaluating building energy-saving effects mainly adopts the trade-off calculation method of energy-saving design standards, that is, according to the requirements of energy-saving design standards, using energy consumption simulation...
