Research on Opening Design Guidelines for Zero-Energy House Based on the Family Life Cycle

Spatial resources and environmental problems caused by population growth are increasingly becoming the focus of global concern. The environmental sustainability of building products has become the research frontier of the industry. Previous research has proved that 25% of energy consumption comes from daily use, and realizing low-energy design based on the whole life cycle is of great significance to promoting the transformation of the building industry. This paper focuses on the wasteful energy consumption problem caused by the changes in residents' behavioral requirements due to the changes in family structure. Based on the family life cycle analysis, this paper explores the mechanism of residents' behavioral requirements and spatial function changes at each stage to clarify the relationship between residents' behavior and building energy consumption. Then, by controlling factors, including Light Correction Coefficient, Effective Daylight Area, window-to-ground ratio, and window-to-wall ratio, and applying the passive design methodology, this paper establishes the zero-energy home opening design guidelines based on the family life cycle. This research guides designers in the design of zero-energy house openings and, at the same time, provides new perspectives for related research in the field of building energy consumption, which helps to promote the sustainable development of the field of architectural design.
