A method for predicting energy consumption of urban residential building system in cold area

Abstract

The invention discloses a method for predicting the energy consumption of a urban residential building system in a cold region, which comprises the following steps: step 1, establishing a database ofenergy consumption influencing factors of the urban residential building system in the cold region; 2, setting the energy consumption estimate formula of each residential building in the urban residential build system as follows: annual energy consumption of each residential building = energy consumption of daily electrical appliances + energy consumption of daily hot water + energy consumption ofrefrigeration in summer + energy consumption of heating in winter; 3, obtaining the energy consumption influencing factors which are significantly linearly related to the annual energy consumption based on the correlation analysis of statistics; 4, establishing a multivariate regression model between that annual energy consumption of the urban residential building system and the influence factorvariable of the energy consumption which have a significant linear correlation to the annual energy consumption of the urban residential building system, and predicting the energy consumption of the urban scale by solving a regression equation. The energy consumption prediction method of the invention can predict the total energy consumption of the existing urban residential building system from the city scale.

Description

technical field [0001] The invention belongs to the technical field of energy consumption prediction of urban residential buildings, in particular to a method for energy consumption prediction of urban residential building systems in cold regions. Background technique [0002] The energy consumption of urban buildings occupies an important proportion in the overall energy consumption of the city, and with the improvement of people's living standards, the energy consumption of urban residential building systems shows a trend of substantial growth. At present, the research on the energy consumption of residential buildings is mostly concentrated on the scale of individual buildings, and the overall energy consumption model of residential building systems at the urban scale is still in the preliminary theoretical stage and has not been widely used and promoted. [0003] The energy consumption of urban residential buildings in cold regions can be seen throughout the year. The ma...

Problems solved by technology

At the same time, the building energy consumption level is also affected by the energy consumption habits of the occupants.

At present, there are not many methods for monitoring and calculating the annual energy consumption of residential buildings during the operation phase. Most of the energy consumption calculations of residential buildings are based on computer software to simulate the energy consumption of individual buildings during the architectural design stage.
