Bosarge Family Education Center – Coast Maine Botanical Gardens
The Bosarge Family Education Center will be the third net zero non-residential building in all of New England, and is only the second commercial LEED Platinum building in Maine. The U.S. Department of Energy’s Zero Energy Buildings Database lists only 8 non-residential buildings nationwide that have achieved net-zero-energy status.
- The walls and roof that make up the building envelope are at least a foot thick and capable of producing an impressive efficiency rating of R40 in the walls and R60 in the roof. The most efficient triple-glazed windows that can be bought in the U.S provide passive solar gain in the winter, while keeping out the heat in the summer.
- To produce the energy load required to achieve NetZero, the building is equipped with 135 photovoltaic panels on the south side of the roof, plus an additional 102-panel array on the ground. Payback from the solar system is estimated at 10 years.
- Rainwater is stored in a 1700 gallon “Gray Water” tank that will be used for flushing toilets and will reduce potable water consumption by over 75 percent.
- Mechanical and electrical engineering systems includes a massive array of onsite solar photovoltaic electricity generation capable of generating 55,184 kilowatt hours.
The structure is a collaborative design effort by a team of highly skilled professional design firms including Allied Engineering, Fore Solutions, Scott Simons Architects, and Maclay Architects.
This project has been cited for numerous awards and designations, including:
- First Place Winner of the NESEA 2013 Zero Net Energy Building Award
- MEREDA Deep Energy Retrofits Presentation – 2011 (Ian MacDonald)
- AIA Maine 2013 COTE Awards (Committee on the Environment) Institutional/Educational Citation Award (third)
