The Wampanoag Headquarters uses about half the energy of a comparable building on Martha’s Vineyard. Fine-tuning the heating and electrical control systems will result in even greater improvement.
The building is elongated on an east-west axis with one story above grade on the north and two stories above grade on the south. 65% of the building’s glass is located on the south facade to promote solar gain in the winter, while east- and west-facing glass was minimized to prevent overheating in the summer. The glass used for the south windows also admits more solar radiation than the low-e glazings used for the other three facades, which reduce summertime heat gain while providing good visible-light transmittance.
Interior lightshelves above the south-facing windows reflect sunlight deep into the first-floor work spaces, which have an open floor plan and high ceilings to make maximum use of the natural light. A controller system adjusts the electric lighting in response daylight levels, and occupancy sensors also help to reduce lighting-energy use.
A ventilation system that provides heat recovery from exhaust air provides excellent indoor air quality with little energy cost. A separate heat recovery system uses exhaust air from the composting toilet and bathroom to produce all the building’s hot water.
Special attention was paid to airtightness because it increases comfort, reduces heating loads, and helps keep potentially damaging moisture out of the building. Airtight construction was verified with a blower door test which helped identify key leakage areas to be resealed.
Along with air infiltration, the design and construction team paid careful attention to insulation levels. The R-22 walls are 2x6 construction with blown-in blanket fiberglass, which fills wall cavities more completely than traditional batts. The vaulted ceilings are insulated to an R-value of 40.
Only the copier room has mechanical cooling. Elsewhere, cooling is provided by operable windows, which allow users to take advantage of the ocean breezes.

| 选址和节水方案: |
The Wampanoag building makes use of an extensive list of resource-efficient, salvaged, and recycled materials.
Old-growth redwood salvaged from discarded beer and wine vats and old-growth Douglas fir salvaged from dismantled warehouse buildings were used in construction. The carpet is made from recycled plastic bottles and its liner is made from compressed recycled newspapers. Ceramic tiles are made from automobile windshields. Doormats are made from recycled tires. Insulation is made from recycled Styrofoam containers. Carpet and natural linoleum were installed without the use of adhesives, and low toxic paints and finishes were used.
A low-cost, easily operated recycling system handles much of the solid waste produced in the building, including paper, plastics, food waste, toner cartridges, glass, aluminum, and batteries. |
| 室内环境品质: |
This is one of few buildings that convert all human waste and washwater to nutrients. A composting system, located directly below the lower floor’s bathrooms, treats human fecal material and urine. Eighty square feet of 36"-deep soil beds in the waiting area and multi-purpose room filter graywater from interior fixtures and appliances (including showers, sinks, dishwashers, and washing machines).
These toilets and greywater systems produce compost and fertilizer, which are collected by a local farmer, and irrigation water, which is used on site.
Water use and pollution are further minimized by highly efficient fixtures.
Previously undeveloped land
Water Conservation and Use
Indoor potable water use: 9,130 gal/yr (34,500 liters/yr)

| 材料选择: |
The building was designed for optimal utilization of passive solar benefits. Extensive daylighting makes the building a comfortable space without wasting energy.
No adhesives were used to install the carpeting or linoleum and low-VOC paints and finishes were used throughout the building. An efficient ventilation system provides excellent indoor air quality with minimum energy use penalty. |
