The Wood Technology Center at Seattle Central College is a 55,000 square foot facility located 2 miles south of the main campus. This center houses programs for Carpentry, Cabinetmaking, and Marine Carpentry. A key component of this project was integrating an industrial facility into an urban setting.
The Wood Technology building required multiple sawdust collection systems for specific construction spaces including rough carpentry, finish carpentry, and wooden boat building. Another unique challenge involved creating booth exhaust systems for laminate and paint within this Seattle Central College facility.
The Furniture Factory is a LEED Silver Certified residence hall furniture manufacturer, located within Stafford Creek Corrections Center. 173 offenders, overseen by 9 civilian staff learn carpentry, upholstery, metal fabrication and other manufacturing trade skills.
Notable mechanical aspects for this project include a 100,000 CFM dust collection system, next-generation high capacity paint application operation, instructional welding and a power-coating operation.
EnerG2 is developing a patented Carbon Technology Platform to enable large-scale production of carbon materials that surpass the limitations of the naturally occurring carbons traditionally used in energy storage applications. Their prototype manufacturing facility in Albany, Oregon, is assisting EnerG2 in the refinement of their large-scale production processes.
Notable mechanical aspects of this project include an ammonia-based central plant brine cooling system, medium pressure steam process heating, vacuum-jacketed liquid nitrogen distribution piping, ultra-high temperature ceramic exhaust systems with afterburner assemblies, and carbon dust containment/filter/exhaust systems.
Washington Corrections Center for Women is located in Gig Harbor, Washington. It has a current capacity of 738 inmates, including minimum, medium, and close unit custody levels.
This project focused on a new health services building, providing clinic, procedure, patient bed, mental health observation, and administrative spaces.
Notable mechanical aspects in the new health services building include pressure controlled isolation spaces, and specialty plumbing in the dental area. The project also required a unique high ventilation and high filtration HVAC system in the trauma rooms.
Centennial Middle School is located just north of the City of Snohomish. Centennial enrolls about 770 7th and 8th graders each year. This project was comprised of classroom and gymnasium additions, as well as an existing building upgrade.
Notable mechanical aspects of this project included an in-slab, hybrid system consisting of radiant heat, a ground source heat pump and a condensing boiler. Additional aspects of this project included dedicated energy recovery ventilators for localized CO2 control and natural ventilation integrated into the existing system operation and controls.
Lake Hills Library, located in Bellevue, Washington, is part of the King County Library System. It is a 10,000 sf community library, integrated into a retail campus.
The project started with a cold shell, and involved a complete mechanical system. Inventrix worked with the owner and design team to implement a raised floor system.
Notable mechanical aspects for this project include underfloor air distribution utilized for the mechanical system, in coordination with flexible power and low voltage distribution. Custom packaged rooftop equipment utilized variable capacity scroll compressors, for fully modulating capacity to support occupant comfort with the underfloor system.
Viktoria High-rise Apartments are luxury apartments located in downtown Seattle. This 25 floor complex was built with a focus on Northwest beauty and eco-friendly materials, along with sustainable building practices.
This building includes energy-efficient heating, cooling, and lighting. As well as, energy-efficient windows, and air-conditioned climate control. Viktoria is currently pursuing LEED certification.
The Public Health Laboratories provide services to protect and improve the health of people in Washington State.
This project involved the design of a 600 ton chiller plant. A 6,000 sf addition was built to house the plant, allowing the existing equipment to continue serving the critical facility during construction and addressing existing code violations in the process.
The owner possessed a strong desire for an energy-conscious design. With that in mind, we performed extensive modeling of the chiller plant, starting with thorough development of present and future cooling loads in the facility. Alternative chillers, towers, and pumping arrangements were evaluated to find the solution that best met the load profile for the facility.
Notable mechanical aspects for this project included: variable primary pumping system for the chilled water loop, installation of a different manufacturer’s control system from the existing facility system including integration of the new system with the existing system, use of variable frequency drives on chillers and detailed sequencing of chiller loading for optimum performance. Also, construction of an extensive acoustical wall around the cooling towers, and use of ultra-low-noise tower fans to provide noise levels adjacent to the building in-keeping with residential requirements.
Border patrol stations ensure a smooth flow of legal trade and travel through their respective borders. Together the Oroville and Colville stations are is responsible for 120 miles of international border. The Bonners Ferry Border Patrol Station patrols from NW Idaho to Western Montana.
The three separate projects were designed simultaneously with the same design team on all projects. VRF/ERV systems were utilized on all three projects. Projects also included a garage/maintenance facility with vehicle exhaust systems and vehicle wash facilities. Life cycle evaluations were performed to determine the lowest life cycle mechanical systems.
Notable mechanical aspects for this project included variable refrigerant flow HVAC systems, high efficiency energy recovery systems and terrorism prevention design.
Washington State Penitentiary is a multi-custody detention campus housing approximately 2,000 inmates. It includes minimum, medium, close custody, and intensive management security levels.
This project involved emergency replacement of an existing chilled water/condenser water system due to a catastrophic failure of a cooling tower. During this emergency project the hospital was a continually occupied facility.
Notatable mechanical aspects included a forensic analysis of a failed hospital chilled water stystem, and the repurposing of a condenser water piping system to a chilled water for air-cooled conversion.
The City of Lynden is located in Whatcom County, Washington. In order to create the Lynden Police Department’s new headquarters, the city chose to retrofit existing commercial buildings.
This project include a centralized HVAC system integrated into a new mezzanine, a new evidence processing laboratory, as well as a secure and climate-controlled evidence storage area.
