The design and construction of an efficient modular zero-energy solar house—a case study of solar decathlon China project “24+35 Housing Home”

Abstract This paper, taking Solar Decathlon China competition project “24 + 35 Housing Home” designed and constructed by Dalian University of Technology as an example, systematically summarizes the design concepts implemented throughout the entire process of the project’s design, production, transportation, and construction, focusing on human habitability, efficient prefabrication, sustainability in energy, and intelligent connectivity. The project is closely aligned with practical situations, with an emphasis on issues of human habitation health in the design of architectural spaces and the configuration of residential equipment. It explores an efficient modular system that merges long-distance transportation with rapid assembly, while also optimizing the design of sustainable energy systems in conjunction with climates and environments. Simultaneously, it integrates smart connectivity technologies, aiming to explore the possibilities of future human habitats. This paper intends to consolidate the strengths and advantages of the competition project and offers insights for expediting the construction of zero-energy solar houses.
