L&I/WSDA Safety and Health Lab
L&I/WSDA Safety and Health Lab
Energy-efficient and balanced HVAC systems supporting a state-of-the-art safety and health lab in Tumwater, Washington.
Description
The L&I/WSDA Safety and Health Lab Training Center is a state-of-the-art facility, offering 53,154 square feet dedicated to food safety, hazardous chemical testing, offices, and conference rooms. The design includes electric vehicle charging stations, high-efficiency water fixtures, low-energy LED lighting, and systems to minimize nighttime light pollution.
Lab areas feature temperature-controlled rooms, analytical instruments, and specialized workspaces, while a larger training center accommodates more students simultaneously. An outdoor area provides space to safely demonstrate heavy equipment like cranes and scaffolding.
Previously, WSDA operated five labs in a former warehouse in Olympia, including food safety, plant pathology, and entomology labs. This new facility centralizes operations into a modern, purpose-built environment.
Project Description
With Washington State’s efforts to decarbonize and transition to 100% clean energy, this project demonstrates sustainable green building strategies. Energy-efficient automatic balancing valves reduce overflow, minimize pump energy, and help the lab achieve consistent HVAC performance.
The facility uses approximately 250 Coil Piping Packages (CPPs), including automatic and manual CPPS – 2IRIS and 1QIB with customer-supplied actuators. Each CPP includes automatic flow limiting valves, unions with optional CPTA and Coin-Op Air vent or Drain Valves, and isolator S assemblies with combination Y-Strainer and Ball Valves, all configured for easy installation and reliable performance.
Products Used
Automatic & Manual CPPS – 2IRIS and 1QIB
Griswold Controls CPPS solutions integrate multiple components into a pre-assembled unit, including flow-limiting valves, isolators, ball valves, Y-Strainers, and test/drain valves. These packages reduce field labor, save installation time, and ensure reliable and balanced HVAC performance across all lab zones.
By combining automatic and manual flow control, the system maintains precise environmental conditions while adapting to changing pressures, making the facility energy-efficient and highly functional.
