The integration of passive-solar and energy-conservation strategies, optimal performance, and on-site renewable power generation make the building 83% more efficient than a minimally ASHRAE-compliant building.
A grid-connected, net-metered photovoltaic array; a closed-loop, ground-source heat-pump system; and a solar-thermal hot water system supply renewable electricity, heating and cooling, and water. Hydronic distribution provides silent radiant heating and cooling, and valance convectors offer individual zone control and much greater efficiency than conventional fan coil units. A planned on-site wind turbine will yield a net surplus of energy for the building.
Careful detailing of the building envelope stands foremost among the strategies used to achieve the project’s ambitious energy goals. Icynene spray foam insulates all exterior walls and roof assemblies, providing an extremely effective air barrier and optimized R-values. Other features that further enhance its performance include:
Offset-stud framing in the exterior walls to eliminate thermal bridging;
Double- and triple-glazed low-e glazing;
Energy recovery ventilators using enthalpy wheels to recapture exhaust heat and moisture and to precondition incoming fresh air;
An extensive energy-monitoring system that records electrical production and usage, as well as overall system performance;
High-efficiency lighting controls and occupancy monitors;
High-efficiency appliances and office machines. |

A simple interior materials palette – most of which can be defined as either "silica" (glass, stone) or "cellulose" (wood) – supports the health of the building’s occupants and local and distant ecosystems while reinforcing the project’s design principles.
The tight building envelope employs spray-foam insulation not only because of its outstanding performance characteristics, but also because it contains no ozone-depleting blowing agents or formaldehyde that could compromise indoor environmental quality.
The Center’s forest research and policy initiatives emphasize the importance of using FSC-certified and sustainably harvested lumber throughout the building. Examples include sustainably harvested ash millwork; certified fir windows; certified maple flooring from Maine; certified cedar shingles, clapboard siding, and trim; and certified framing lumber and decking to the extent possible.
Stone walls rely largely on fieldstone and glacial erratics drawn from the site.
Careful selection of furnishings favors products with high recycled content in aluminum, fabrics, desk substrates, veneer, and steel components. Examples include task chairs and desk systems with high recycled content and conference tables from sustainably harvested or recycled sources. |

The building lies within the watershed of Oyster Bay, a coastal pond at risk from nitrogen. Within this context, the presence of a pair of local research and policy programs studying the forests and waters of Cape Cod brings the global reach of the Center’s initiatives much closer to home. The Center develops techniques using satellite imagery to measure one widespread negative effect of development on coastal ecology. Excessive fertilization – largely created by conventional septic systems – results from wastewater discharge generated by population growth.
The Center’s policy and research programs and the building’s location within a sensitive coastal ecosystem made it imperative for the design of the project not to diminish local water quality but, rather, to enhance it where possible. A wastewater treatment system renders visible these research activities. As waste material moves through this innovative septic system, the Center’s soils science department collects data as they experiment with alternative denitrifying strategies. The building also supports best practices with water-conserving fixtures.
Permanent gravel parking areas manage stormwater on-site, as does a bioswale that directs runoff into a constructed wetland. A 1,200-gallon tank captures the rainwater required to achieve the goal of zero landscape irrigation, and a wildflower meadow replaces most of the lawn. |

The design seeks to integrate inside and outside spaces by providing daylight, fresh air, and access to views throughout the building.
The open two-story “Commons” area at the junction of the two structures serves as the physical and visual locus for occupants of both sections. Large expanses of glass offer views into the forest canopy to the northwest and to the rhododendron garden to the southeast. This visual connection produces a prevailing sense of integration with the surrounding landscape.
Skylights direct light to interior spaces, and full-height windows in the new wing open to the surrounding forest. The use of double- and triple-glazed low-e glazing in these elements simultaneously serves building performance, aesthetics, and human comfort, providing maximum efficiency and enabling staff to rely on natural daylight.
Individual comfort and control of the indoor environment form another theme sustained throughout the project, with its operable office windows, fresh-air ventilation systems, and user-controlled temperature and lighting. A building monitoring system helps maintain comfortable temperature and humidity levels. Separate ventilation systems in laboratory spaces and low-VOC materials, paints, and adhesives further optimize indoor environmental quality. The open cell structure of the building’s Icynene insulation virtually eliminates subsequent offgassing of uncured materials. |
