ArchEcology offers practical, cost-effective solutions for your green building project
Founded in 2006, our practice began with a passion for sustainable buildings and vast experience working with developers and long term property holders. ArchEcology combines years of design and construction experience, with extensive LEED consulting on a wide range of project types.
This spectrum of experience has given us a holistic perspective on optimizing building performance that extends beyond design and construction into ongoing energy efficiency and the post occupancy operations of existing buildings. A building’s performance is more than just the sum of its individual systems.
We seek sustainable solutions to operating healthy buildings cost-effectively.
Founder and managing partner, Nancy Henderson, offers 17 years of architectural experience more than half devoted entirely to green building design. Her commitment to sustainability grew from a passion for affordable housing into a mission to bring healthy, green practices to the design, construction and operation of every building she touches.
Partner, Michelle Rosenberger, has 20 years of experience working with designers, engineers, and contractors on projects ranging from warehouses to highways and from retail to low income housing. She acts as project manager on numerous ArchEcology projects and is also responsible for workshop facilitation and educational materials.

Shoreline City Hall
Shoreline wanted a City Hall that modeled the kind of sustainable development they envision for their future. Their new four-story, 66,000 SF LEED Gold civic center combines city council chambers and public meeting rooms with civic administrative services. Green building features serve energy reduction and indoor environmental quality goals, while educating the public about sustainability. From a green roof atop the Council Chamber complete with solar thermal panels that provide hot water to restrooms to electric car charging stations in the garage that are powered by photovoltaic panels.
Project Details
- This former brownfield site uses on-site swales and rain gardens to handle 100% of the rainwater that falls on the site.
- Solar thermal and photovoltaic panels generate enough on-site power to earn the project a LEED point.
- An interactive touch-screen kiosk in the main lobby shares how much energy the building is creating or saving; and how much water the green roof is harvesting.
Seattle Sustainable Masterplan
The City of Seattle’s Capital Projects Division (CPD) owns and maintains more than 100 City buildings, ranging from fire stations to City Hall. LEED-Silver has long been the standard for new construction over 5,000SF, but the CPD needed a consistent way to implement green building strategies for their small renovations, tenant improvements, and infrastructure replacement projects. Via a series of facilitated workshops, ArchEcology created a centralized resource of sustainable measures, and a process to compile a customized list of targeted measures for each project.
Project Details
- Comprehensive digital resource of sustainable measures
- Feedback tool for measuring progress
- Established performance standards for each measure allowing continuing improvement
- Implementation process providing customized subset of strategies for each project
1521 Second Avenue
The developer, Opus NW, realized a height bonus for pursuing LEED-NC Silver on this 140-unit luxury high rise condominium tower in downtown Seattle. The urban location and spectacular access to daylight and views are complemented by a focus on indoor air quality measures, highly efficient mechanical and electrical systems, sophisticated building automation, and local and recycled content materials.
Project Details
- 140-unit luxury high rise condominium tower
- Glass curtain wall construction
- Structured parking
SHA Denny Terrace Energy Audit
ArchEcology audited energy use at Denny Terrace, one of SHA's oldest apartment buildings. Using data collected from on-site investigation, available plans and tenant schedules, we created an energy model of the building. We then calibrated our model using actual meter readings to run numerous potential energy conservation measures. Proposed improvements were evaluated against not only initial cost and potential energy reduction, but also against durability and low maintenance requirements. Our recommendations were instrumental in obtaining $10M in green retrofit funds.
Project Details
- Improvements will reduce energy use by 35% over current annual use
- Fixture upgrades will reduce water use by 30% over current annual use
- Electric heat sources, selected over gas, reflect maintenance considerations
- Post occupancy audit will verify reductions
BMW Seattle Sales Building
Convenient to downtown, the BMW Seattle Sales Building is a two story 50,000SF urban showroom consisting of automobile display, storage, and offices for sales and support staff. The sleek industrial setting of geometric metal and concrete is enriched with extraordinary daylighting and views of the city. BMW hallmark quality is evident in the attention to sustainable construction practices, material selections and energy efficient fixtures and systems that resulted in LEED-NC Silver certification in 2010.
Project Details
- A light colored roof reduces solar heat gain and helps to keep the building cool in summer
- Low flow water fixtures reduce use by 40% over conventional fixtures
- Thermal glass, added insulation and efficient energy systems reduce energy use 27% over the average building of this type
- 81% of the construction debris was salvaged or recycled and did not enter the landfill
Lakeview Plaza
This corporate campus in Kirkland, WA pursued LEED-Silver certification for their Core and Shell development in hopes of attracting a desirable Class A tenant. By providing efficient systems and green infrastructure, these buildings enhance their tenant’s ability to pursue green practices of their own. A large, high technology firm negotiated a lease before the buildings were even complete and is now pursuing LEED certification on their own tenant improvement.
Project Details
- 190,000 SF campus of 3 office buildings
- Green housekeeping and integrated pest management
Esterline-Korry Manufacturing
Esterline Control Systems achieved LEED Certification at their new Everett manufacturing facility in 2010. To reduce building energy use, small highly efficient heat pump units are clustered to require no electrical reheating. High-bay T5 fluorescent lamps provide long life and instant re-strike, which combined with generator power allows these fixtures to serve 'double duty' as normal lighting and emergency egress. Low flow water fixtures throughout the building reduce water consumption 40% over conventional use. Green cleaning and integrated pest management programs preserve the healthy indoor environment.
Project Details
- An exemplary amount of recycled content building materials amounting to well over 30% of material costs were used for this facility, including gypsum wallboard, insulation, flooring, acoustical ceiling systems, steel and rebar.
- By selecting an appropriate palette of native and drought tolerant plants and designing a highly efficient drip irrigation system, annual water consumption for irrigation will be reduced by over 70%.
YMCA Matt Griffin
The 52,000SF YMCA Matt Griffin in SeaTac, WA achieved LEED Gold in 2010. The new community recreational facility focused on careful construction practices, extensive daylighting, non-toxic material selections, efficient lighting and heating equipment, and a healthy, comfortable indoor environment. Though certification was a requirement of funding, these sustainable measures were selected to complement their strong kids and families mission.
Project Details
- On-site wetlands restored to their natural, vegetated state help reduce neighborhood flooding.
- Increased ventilation and demand control in exercise rooms keeps occupants comfortable, while reducing energy use.
- Local materials contributed more than 35% to overall building material costs.
- Enhanced third party commissioning ensures that all the building’s energy systems function as intended
Legacy Corporate Center Redmond
For this LEED-Gold Class A office space, Legacy Partners focused on sustainable building materials, indoor air quality measures, and efficient energy systems and infrastructure that would provide the most benefit for future tenants. In addition to sustainable guidelines for tenant improvements, Legacy has also incorporated an integrated pest management program for the facility.
Project Details
- 3-story 103,883 SF office building with two levels of below grade parking
- 14% recycled content and 25% local building materials
- 69% Forest Stewardship Council certified wood products
- 32.9% energy reduction over ASHRAE, receiving 7 out of 8 possible energy points
