[youtube=http://www.youtube.com/watch?v=JkzZP42Upc0]Da Vinci Arts Middle School in Portland celebrated a roofing renaissance at its new LEED Platinum-anticipated, net zero energy, high performance classroom building on April 10.The school held an open house to showcase the latest innovation of its groundbreaking building: a roof constructed with integrated photovoltaic (PV) solar tiles.
Bonneville Environmental Foundation (BEF) donated 150 32-watt SolarSave® tiles from Applied Solar, Inc. that are being integrated into the roof and wired to an inverter in the building. When combined with a smaller, pole-mounted PV array already located at the site, these two systems will generate up to 6.3 kW of energy — enough to provide the 1,490-square-foot building’s electricity needs — making it the first net zero energy, LEED Platinum-anticipated, freestanding public school classroom in the nation.
The building will house a music room, two practice rooms and a small recording studio. Scheduled to be completed this summer and to be filled with music-making students in September, the building has a high thermal mass (thanks to thick walls) and boasts an innovative design that incorporates natural ventilation and day-lighting as well as nightly venting to regulate heating. It is being built with non-toxic, environmentally friendly materials and processes and will employ an artistic storm-water management system that connects to an adjacent garden.
Designed as a showcase of technologies for future district renovation and new construction projects, the building has benefited from more than $500,000 in design, construction and consulting services donated by the community, including significant contributions from SRG Architects, Todd Hess Building Co. and PBS Engineering.
The da Vinci High Performance Classroom project is the sixth collaboration between Portland Public Schools and the Bonneville Environmental Foundation’s Solar 4R Schools program. In addition to donating the solar tiles, BEF also consulted with the engineers and architects during the construction process and contributed educational materials and teacher training opportunities through its Solar 4R Schools program to help make the building a focal point of learning both about music and renewable energy.
BEF also has worked with Portland Public Schools to provide renewable energy education and solar demonstration installations at Cleveland and Lincoln high schools, Rosa Parks Elementary School and Sunnyside Environmental School, as well an earlier project at da Vinci. Previous projects were funded with the support of Energy Trust of Oregon and Portland General Electric.
The da Vinci classroom project was a 2007 recipient of the City of Portland Office of Sustainable Development’s Green Investment Fund. Updates on the building’s construction are available at http://facilities.pps.k12.or.us/.docs/pg/11207.
