A Method for Predicting Energy Consumption of Urban Residential Building Systems in Cold Regions

Abstract

The invention discloses a method for predicting energy consumption of an urban residential building system in a cold region, comprising the following steps: step 1, establishing a database of factors affecting energy consumption of an urban residential building system in a cold region; The formula for estimating energy consumption of residential buildings per household is: annual energy consumption of each residential building = daily electrical energy consumption + daily hot water energy consumption + summer cooling energy consumption + winter heating energy consumption; step 3, based on statistical correlation analysis Obtain the energy consumption influencing factors that are significantly linearly correlated with the annual energy consumption; step 4, establish a multiple regression model between the annual energy consumption of the urban residential building system and the energy consumption influencing factors that have a significant linear correlation with it, and complete by solving the regression equation City-scale energy consumption forecasting. The energy consumption prediction method of the present invention can predict the overall energy consumption of existing urban residential building systems from the urban 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.
