Development and construction of net-zero-energy house for solar decathlon Europe 2012

Abstract

Chiba University has participated the international solar housing competition called Solar Decathlon Europe 2012. This paper reports the design process and construction result of the proposal called Omotenashi House. Chiba University has been designing a net-zero-energy and food self-sufficient model since 2011 including insulation system, landscape, structural planning, PV system, natural and artificial lightings, and active and passive systems. Finally Omotenashi House has been exported to and reassembled in Spain in 12 days, and measured its high energy efficiency and electrical balance with low VOC emissions.
