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.
- 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.
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.
- 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
Wallace Properties, the NAIOP 2012 Developer of the Year, developed this new 6-story multi-family residential building which combines 108 units with ground floor commercial space and below grade parking on an urban site. Sustainable measures focused on indoor air quality, efficient energy and water use, and construction practices. The project achieved LEED Silver in 2012.
- Energy model predicts 21% annual energy reduction over conventional
- Low flow fixtures reduce water use more than 40% over conventional
- 14% recycled content matterials by cost, with 27% locally sourced
- Low emitting adhesives, paints and flooring throughout
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.
- 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
ExOfficio renovated an existing sporting goods building in a light industrial area into a new headquarters. The new space incorporates conventional office and conference rooms with spaces for garment design and mock-up. Wholesale customers come to the building to see new product lines for upcoming seasons. The floor plan is open to allow for flexibility with space planning. Renovations include a new building entry canopy, new skylights and clerestory, a new light colored roof with added insulation, and new high performance glazing.
- Envelope improvements, along with high efficiency HVAC systems, a 25% reduction in lighting power, Energy Star appliances and extensive daylighting strategies reduce overall energy use a projected 15%.
- Existing wood flooring was salvaged, and minimal new finishes were used.
- Reuse of staff furniture and furnishings topped 80% and earned an ID credit.
Google Tenant Improvement
This project began with a three building corporate campus in Kirkland, WA which pursued LEED-Silver certification for their Core and Shell development. By providing efficient systems and green infrastructure, they attracted Google as a tenant. Google received LEED Platinum for their subsequent 2 building tenant improvement. This achievement marked the beginnnig of a commitment to LEED certification which has set a Gold standard for all of their new construction and tenant improvement efforts.
- 189,412sf improvement received 9 of 12 possible energy points for equipment efficiency and lighting power reductions.
- Achieved 13 of 17 indoor environmental quality points for ventilation, low VOC products and stringent construction practices
- Exemplary performance included 44% water reduction, 74% furniture reuse, 46% regional materials by cost and 100% green power
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.
- 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.
- 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
Overlake Medical Office Building
Overlake Medical Office Building is a nine story, 164,486 SF core & shell construction located in Bellevue, Washington. This large medical office building supports an adjacent hospital with medical‐oriented functions. For occupant comfort and health, the mechanical systems are designed to increase ventilation, provide outdoor air delivery monitoring for all spaces, and provide comfortable thermal environments. Stringent indoor air quality practices throughout construction minimized the intrusion of dust and particulates to protect indoor air quality.
- Structured parking is shaded by a combination of highly reflective roofing materials and a green roof courtyard to keep the building cool.
- Low flow water fixtures will reduce water consumption by a projected 47% over conventional ones.
- Low VOC adhesives, paints, flooring, and no urea formaldehyde added wood composite materials minimized off‐gassing during and after construction. With occupancy, green housekeeping practices will encourage a healthy indoor air environment.
ArchEcology can help you plan your approach toward sustainability
Humans need the natural and the built environment. High performance green buildings are best for both. ArchEcology can help you plan your approach to sustainability, define the costs and benefits of your choices, and measure your performance, before,during and after construction.
