Example Embodiment

[0039] Example 1:

[0040] A performance-oriented multi-objective optimization design method for buildings, including the following steps:

[0041] 1) First determine the variables in the architectural design: orientation, shape factor, north window-to-wall ratio, south window-to-wall ratio, east window-to-wall ratio, west window-to-wall ratio, external wall heat transfer coefficient, external wall thermal inertia index, roof Heat transfer coefficient, roof thermal inertia index, heat transfer coefficient of external windows. And limit the value range of each variable, which is based on the needs of the owner and the current national and local building energy efficiency design standards and design codes such as the "Design Standard for Energy Efficiency of Residential Buildings in Hot Summer and Cold Winter Areas".

[0042] 2) Set the performance target of the building design, select the building's annual energy consumption, indoor thermal comfort, and indoor average natural lightin...

Example Embodiment

[0054] Example 2:

[0055] A typical residential building type in Chongqing is selected as the analysis case. The total construction area of ​​this case is 600m 2 , 3 floors high, 2.8m high, 2 households on each floor, each building area is the main unit area of ​​a 3-person family in Chongqing, about 90m 2 . Use a multi-objective optimization model to find a building design that not only saves energy consumption but also ensures indoor thermal comfort. Specific steps are as follows:

[0056] 1) First determine the variables in the architectural design, and limit the value range of each variable: determine the variable type and limit its value range:

[0057] Since the building layout, floors, building area, and body shape coefficients have been limited, the remaining 10 design variables given in Table 2 need to be solved. According to the "Design Standard for Energy Efficiency of Residential Buildings in Hot Summer and Cold Winter Areas", the variation range of these 10 variables ...

Abstract

The invention discloses a building multi-objective optimization design method based on performance orientation. The method includes the steps that variables in building design are determined, the value ranges of all the variables are defined, performance objectives of building design are set, all fitness function value calculation tools are determined, NSGA-II algorithm relevant parameters are set, a first population is obtained through operation of an NSGA-II algorithm, the fitness function value calculation tools are used for evaluating each individual in the current population, a next population is generated, and whether conditions for cycle termination are met or not is judged. All individuals in a finally-generated population are a set of optimal design schemes.

Description

technical field [0001] The invention relates to a performance-oriented multi-objective optimization design method for buildings, in particular to an automatic comparison and selection of architectural design schemes and an algorithm based on goals including building operation energy consumption, indoor environmental thermal comfort, and indoor lighting effects. Background technique [0002] (1) Architectural Design Requirements [0003] People spend 80% of their lives indoors. Improving the indoor environment and improving the quality of the living environment are closely related to people's livelihood. With the rapid rise of my country's social and economic level, improving the quality of life in living spaces has gradually become a hot spot for residents. Improving The indoor thermal environment has become an urgent need of the people. At the same time, energy issues have always been an important issue for national development. In 2014, China and the United States signed a...
