Hillsboro School District: Rosedale Elementary School

Rosedale Elementary School is representative of Hillsboro School District’s commitment to energy efficiency and building system optimization—it was the first LEED certified elementary school in the district. The two-story school was a new construction.  Included in the facility are classrooms, administration areas, technology and computer labs, food service preparation and serving, and a gym.  This school has the capacity for 600 students and staff, and was the newest of Hillsboro’s expanding district.

Scope: NWESI provided Commissioning services from design to completion of construction, helping to attain LEED Gold certification. Commissioned equipment included

    • HVAC mechanical, (7 air handlers, 1 make-up air handler, 8 exhaust fans, 2 boilers, 13 pumps, 3 unit heaters, 3 split air conditioning systems)
    • Building Automation System

NWESI provided TAB for this project during the summer of 2009. HVAC is provided by multiple variable air volume (VAV) roof-top air handling units (AHU’s) with Dx cooling. These either serve multiple zones by way of VAV terminal units with reheat, or single zone common areas. All AHU’s have supply and relief fans. Also roof mounted were several small split system air conditioning units, roof-top exhaust fans, and a make-up air unit for the kitchen hood.
