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 green building 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.

7th & Madison
For their new Class A office building in downtown Seattle, OPUS NW has recevied a LEED-Gold rating. Extensive indoor air quality measures, complemented by ample daylight and views, encourage a healthy, productive workplace environment. Efficient HVAC and lighting systems reduce operating costs. A light-colored roof and underground parking reduce heat gain to help keep the building comfortable. Low flow fixtures and high efficiency irrigation reduce potable water use a projected 40%.
Project Details
- 9-story 197,000 SF commercial office tower
- 2,500 SF of retail/restaurant and four levels of below grade parking
- 18% projected energy use reduction despite extensive glazing
- More than 4,656 tons of construction waste diverted
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
UPS Facilities Services
The University of Puget Sound’s Facilities Services in Tacoma, Washington consists of three wood- and steel-framed buildings which house 23,490 square feet of offices, storage and workshops that serve as home base for campus grounds and maintenance staff. Building A contains administrative offices, reception, a conference room, lunchroom and locker room. Building B contains the carpentry and mechanical shops. Building C is dedicated to groundskeeper equipment and storage. All three buildings received LEED-NC Gold certification in 2009.
Project Details
- Operable windows and efficient gas heaters reduce energy use
- Skylights, daylight controls and LEDs provide light where it's needed
- Low flow water fixtures reduce water use an exemplary 45% over conventional ones
- Certification and sustainable operation supports campus-wide mission
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
Cobb Building Renovation
When this historic medical office building in downtown Seattle had outlived its useful life, Unico decided to convert the building into apartments. The Historic Tax Credits that made the project’s financing possible imposed many challenges on pursuing LEED certification. Envelope improvements were limited to applying a low-E coating to existing glazing. Efficient compact fluorescent light fixtures, Energy Star appliances and a hybrid heat pump system for heating and air conditioning conserve energy. The project received LEED-Silver certification in January of 2009.
Project Details
- 1910 building listed on the National Historic Register
- 92 market rate apartment units
- Hybrid heat pump system to provide heating and cooling
- Operable windows with low-E coating
Glade Spring Spa
The Glade Spring Spa is located within the 6,300-acre resort community Suncadia in Roslyn, WA. The wood frame structure is comprised of two wings that form the shape of an “L” around the outdoor spa areas. An interior water feature wall brings natural elements inside the facility. Outdoor spa amenities include separate cold, medium and hot temperature mineral pools surrounded by flagstone pavers, wooden bridges and trellises. The project achieved LEED-Silver certification in June of 2009.
Project Details
- 1 story 9,880 SF spa facility including: treatment rooms, lounges, retail, offices and storage.
- Man-made swales control site water run-off
- Comprehensive green purchasing for spa treatments and retail operations
- 45% local building materials used
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.
