User behavior-based method for optimizing building energy conservation design in severe cold areas

Abstract

The invention discloses a user behavior-based method for optimizing building energy conservation design in severe cold areas. The method comprises the following steps of: aiming at special weather conditions in severe cold areas, carrying out analysis by utilizing survey data so as to obtain a building design parameter set of actuating energy conservation behaviors; learning behavior measured data by applying a machine learning algorithm in a data mining technology so as to obtain a more correct user random behavior mode; obtaining an optimization energy conservation performance design parameter set through a behavior mode optimization traditional prediction model and a Bayesian theory-based Gaussian process correction prediction model; coupling the actuating energy conservation behaviors and the optimization energy conservation performance design parameter set to obtain an optimized parameter set; and finally combining an optimal design parameter set and an energy consumption prediction model to establish a new process for building energy conservation design in the severe cold areas. According to the method disclosed by the invention, the influences, on the prediction models, of uncertainty can be reduced, and a more optimal parameter screening process, more correct energy conservation effect prediction, a more rational building energy conservation design process and a more correct estimated building design result can be obtained.

Problems solved by technology

In the current simulation analysis work, more emphasis is often placed on meteorological parameters, enclosure structures, and equipment systems, and human behavior is mostly described in a simplified manner, which cannot effectively reflect the various significant impacts of human behavior. Therefore, In many cases, the simulation analysis results deviate greatly from the actual situation, which affects the accuracy of analysis, prediction and evaluation of building energy consumption

Since the existing building energy consumption and performance simulation platform cannot accurately and specifically describe the behavior of building users, the simulation results are difficult to reflect the actual energy c...
