Problems solved by technology

When optimizing, on the one hand, designers have many optimization combinations to choose from; on the other hand, they cannot intuitively judge whether each design combination produces the desired effect, which eventually leads to an increase in energy consumption or a reduction in thermal comfort while improving thermal comfort. Indoor thermal comfort and energy consumption are increased, and the best design solution cannot be searched

Embodiment 1

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

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

[0042] 2) Set the performance goals of architectural design, and select the building's annual energy consumption, indoor thermal comfort, and...

Embodiment 2

[0055] A typical residential building in Chongqing is selected as an analysis case. The total building area of ​​this case is 600m2 2 , 3 storeys high, 2.8m high, 2 households per floor, and the construction area of ​​each household is the main household area of ​​a family of 3 in Chongqing, about 90m2 2 . A multi-objective optimization model is used to find architectural design solutions that can save energy while ensuring indoor thermal comfort. Specific steps are as follows:

[0056] 1) First determine the variables in 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 shape coefficient have been limited, the remaining 10 design variables given in Table 2 need to be solved. According to the "Design Standards for Energy Conservation of Residential Buildings in Hot Summer and Cold Winter Areas", the variation ranges of these 10 variables are ...

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...
