Ene-mane House 2015: Intercollegiate Zero-Energy House (ZEH) Design Competition

A team of SIT students and faculty members won the First Prize and the People’s Choice Award for their project, Tsugi no Sumika, at Ene-mane House 2015 which was held on October 31.
At an Ene-mane House competition, universities compete with their projects for next-generation residences which incorporate such themes as “energy,” “life” and “Asia.”
Each team designs, builds, performs test-runs and showcases its housing model. SIT entered the competition for the second time this year and had won People’s Choice Award previously.

The participating universities for Ene-mane House 2015 were Kanto Gakuin University, Yamaguchi University, Ritsumeikan University, Waseda University and Shibaura Institute of Technology. The SIT team, with 5 faculty members and 47 students, was led by Dr. Takashi Akimoto, Professor of Department of Architecture and Building Engineering. The SIT team members combined their diverse set of skills in designing, simulating, structural development to plan and build their ZEH model.

The SIT team aimed to cut energy consumption by 50% with their proposal: the installment of a high-performing ventilation system and the use of Wood-ALC, low-carbon wood which is rarely used in contemporary Japanese architecture, and cross-laminated timber (CLT) panels for both good thermal insulation and storage and energy efficiency. The house was divided into units which can be pieced together, renovated and expanded in ways suitable to its inhabitants’ potentially shifting, diverse lifestyles.

A showcase of all of the housing projects took place in Minatomirai, Yokohama City in Kanagawa Prefecture. As part of the evaluation process, test-runs on running hot water and lights were performed on each housing project where only 3 students were allowed to enter the house freely.
Competing teams presented their projects on October 31 where they were voted on by visitors and a panel of judges. The SIT team won the First Prize and the People’s Choice Award.
The builders of Tsugi no Sumika will move the house to Fukushima Prefecture – as they did their project last year – and continue their research in new building materials including low-carbon wood and cross-laminated timber.
