SAN FRANCISCO, Calif.—Pacific Gas and Electric Company (PG&E) and the American Institute of Architects, California Council (AIACC) today announced the winners of the sixth annual Architecture at Zero competition for zero net energy (ZNE) building design. The competition has awarded six student and professional winners with a total of $25,000 in prizes.

For the sixth year of the PG&E-sponsored competition, contestants designed ZNE housing at the San Francisco State University campus. With 60 entries, this year’s competition garnered double the amount of applicants as in previous years. Applicants designed plans for student housing that will be ZNE, producing as much clean energy as is used during a year through energy efficiency and onsite renewable energy generation such as rooftop solar.
 
Preparing for the next generation of building design, the competition encourages architecture, engineering, planning and design students or professionals to get into a ZNE mindset.
  
“California state policy calls for all new homes to be ZNE by 2020 and all new commercial construction to be ZNE by 2030.”California state law requires all new homes to be ZNE by 2020 and all new commercial construction to be ZNE by 2030.

 

About Romain Dechavanne’s project:

The project is inspired by the eucalyptus canopy already on the site and aims to create a park of trees and buildings on the campus. This project aims to achieve more than zero net energy consumption, it aims to produce more energy than it consumes. The buildings will mainly produce electricity through their photovoltaic canopy. The extra electricity produce each day, mainly on peak hours (near noon) but with low electricity demands will be used to charge electric car batteries to provide green transportation to the university. The electric car batteries will also work as energy buffers, to store each day energy that can also be used during the night in the buildings. So theoretically, thanks to the sun and bio mass, the project could be self-energy sufficient and don’t need any energy supplier. To achieve a high comfort standard, the building will catch as much sun as they can in the winter and as less as they can in summer. This will be achieved by big openings in south, west and east facade with different kinds of solar protections. The buildings are based on a concrete structure (as Le Corbusier’s domino house). This structure will provide a good inertia to the housings. The facade walls will be made of prefabricated wall elements with a high insolation coefficient based on the Panobloc technology from Techniwood®. The conjunction of both those elements will provide a good thermal comfort to inhabitants all year. Heating will be provided by thermal pumps and mechanical ventilation which will be fed at 100% by the photovoltaics panels.
