21 Acres Center Receives LEED Platinum Certification.
21 Acres announced recently the receipt of LEED ® Platinum certification by the U.S. Green Building Council (USGBC) in the category of LEED for New Construction v2.2 rating system. The 12,000 square foot building was awarded the highest Leadership in Energy and Environmental Design certification for its integration of innovative building and on-site systems.
The 21 Acres Center for Local Food and Sustainable Living has the unique distinction of being surrounded by a bio-diverse, certified organic farm. The building houses a year-round retail farm market, a commercial kitchen, offices and spaces for classes, meetings and events. The project is an ongoing effort to explore the leading edge of sustainable practices through engagement with the local community.

- May incorporate sustainable materials in their construction (e.g., reused, recycled-content, or made from renewable resources);
- Create healthy indoor environments with minimal pollutants (e.g., reduced product emissions); and/or
- Feature landscaping that reduces water usage (e.g., by using native plants that survive without extra watering).
Green buildings are designed to reduce the overall impact of the built environment on human health and the natural environment by:
- Efficiently using energy, water, and other resources;
- Protecting occupant health and improving employee productivity (thermal comfort); and
- Reducing waste, pollution and environmental degradation.
Key Sustainable Features in the Center for Local Food and Sustainable Living
Heating, Cooling and Ventilation System Efficiency (HVAC)
- Insulating concrete forms (ICF) used to form the exterior walls and some interior walls. Some (but not all) of the insulated concrete forms (ICF) were 100% recycled expanded polystyrene. (http://www.apexblock.com)
- Earthen berm built along the south wall of the building’s lower floor.
Ground source heat pump system
- Radiant floor
- Pre-heat “hot” water
- Energy recovery ventilation
- Skylights, clerestory windows, energy efficient lighting
- Reduces operating costs by decreasing power used to mechanically ventilate and cool.
- Reduce building energy use and thereby also reduce the environmental impact and external resource requirement/impact.
- 26.1 kW solar photovoltaic roof-mounted system.(http://www.sunergysystems.com/)
- C.E.S. Smart Distribution Panels (digital circuit breakers)
Computerized Electricity Systems (http://www.c-e-systems.com)
- Grey water treatment (Nibler, http://www.thenibblercompany.com/)
- Biofilters (Glendon, http://www.glendon.com/)
- Composting toilets (http://www.clivusmultrum.com/)
- Living Roof (http://www.solterrasystems.com/)
- Low flow fixtures
Other Sustainability Features:
Geopier Foundation System is a foundation alternative that
- Substantially reduced the number of truck transports and accompanying emissions.
- Uses aggregate rock used instead of concrete for piers. (http://www.geopier.com/index.asp?id=11)
- 21 Acres is preparing to take part in the EV Project by installing two electric vehicle charging stations. The EV Project is an initiative launched in 2009, overseen by ECOtality, Inc. and funded by the U.S. Department of Energy. The analysis of data collected at EV Project charging stations will be used to improve North America’s electric vehicle charging infrastructure. (http://www.theevproject.com/)
