Washington International School Science Building

Washington International School (WIS) transformed its Tregaron Campus with a dynamic new science building to elevate STEM learning and champion sustainable design.

GHT provided MEP engineering design and fire protection services for Le Centre Brown Science Building at Washington International School’s Tregaron Campus. This multi-level facility features classrooms, dining areas, robotics labs, and multipurpose spaces.

At the heart of the building is a state-of-the-art laboratory wing, home to biology and chemistry labs, prep areas, and a design tech lab. These spaces are powered by a centralized exhaust system and fume hoods designed to meet rigorous safety and ventilation standards. To further enhance lab operations, GHT integrated a Reverse Osmosis Deionized (RODI) pure water treatment system, ensuring high-quality water for sensitive experiments and equipment.

The building’s HVAC system features a 100% outdoor air unit with energy recovery, tailored to meet both general and lab-specific ventilation needs. While the team explored a geothermal heat transfer system during the design phase, the school opted out due to cost considerations. Nevertheless, the project delivered notable reductions in energy consumption and is targeting LEED Gold certification.
