Owner: King County
Architect and Engineer: HDR
Commissioning: Wood Harbinger
Construction Management: Parametrix
Total SF: 40,000 square feet
Location: Renton, WA
Expected Completion: 2022
Energy Performance: Targeting LBC Energy Petal Pathway
The Central Maintenance Facility, called the Renton Shop, is the headquarters for the Operations and Maintenance section of King County Parks, and the new facility will help improve and facilitate its work across the County. The facility will include a crew/ administrative building, shop building, a storage building and (2) covered storage structures, a parking lot to accommodate both Operations’ fleet vehicles, personal vehicles and electric vehicle charging stations and an equipment wash pad. The facility has been designed to achieve Energy Petal certification with the International Living Futures Institute and achieve net positive solar energy production.
The project is targeting the International Living Future Institute's Zero Energy Certification as a base goal and Energy Petal Certification as a stretch goal. This project is one of ten green building projects selected to further King County's 2015 Strategic Climate Action Plan.
The facility is designed to reduce energy loads and generate solar power on site. The goal for Zero Energy certification is to produce a net annual consumption of zero energy. Energy Petal Certification contains the same requirement, plus additional power production on site achieving net positive energy production (at least 5% more solar energy production than consumption), and battery backup for resiliency.
