Solar Ark 3.0: A lightweight, energy-efficient house based on smooth poly-hypar surface structures

This research addresses energy consumption challenges in the design and construction of concrete freeform surface architecture. It proposes an integrated design approach centered on smooth poly-hypar surfaces, serving as a mediator to amalgamate architectural smoothness, structural stiffness, construction convenience, and building energy efficiency from the initial design phase. To testify the versatile functionality of smooth poly-hypar surfaces beyond structural loadbearing, they are employed in the design and construction of a Solar houseda prototype aimed at establishing an energy-efficient modular design and construction system for concrete-freeform surface buildings. This approach capitalizes on the unique structural and geometrical properties offered by smooth poly-hypar surfaces. By leveraging this special geometry, the methodology transcends individual stages, encompassing the entire integrated process and overcoming limitations associated with traditional sequential design strategies. It underscores the interconnected nature of design, construction, and sustainability considerations. (c) 2024 The Author(s). Publishing services by Elsevier B.V. on behalf of KeAi Communications Co.
