Hollis School District Energy Upgrades
Over the course of two summers, Structure Tone worked with Hollis Upper Elementary School and the Hollis Primary School to improve their energy efficiency measures and update their heating and electric systems. As a first measure of energy conservation, all the lighting in the schools was replaced with LED fixtures that use 75% less energy. The more drastic change in energy efficiency came when we replaced sections of the school’s existing roofs to install new solar panel systems. In total, over 300 panels were installed using the 100KW PVA system. Before starting the project, the buildings’ existing conditions were reviewed to ensure the program could be installed efficiently and be able to successfully produce power to the schools. Since the solar panel installations, the schools have received energy recovery credits with state agencies.
In addition to the energy efficiency upgrades, Structure Tone made significant improvements to the Lower Elementary School’s building envelope. The exterior envelope had been built with a small gap which had allowed outside air in, introducing moisture into the building. The project team worked with designers to help create a solution that sealed the entire roof perimeter and replaced the HVAC controls throughout the building. The exterior skin of the building received a new exterior wall system which incorporated new metal stud framing, spray foam insulation plywood and Hardie Plank siding. New energy efficient windows were installed replacing all the existing perimeter windows in the school.
The building received a new energy-efficient exterior envelope and new interior heating and cooling system which will accomplish the energy savings the client is looking to achieve.
