The Annacis Centre for Research and Education (ACRE) is a 17,000 sq. ft. leading edge, locally-based wastewater research facility located in Annacis Island.  It is located beside the Annacis Island Waste Water Treatment plant. The Centre is equipped with laboratory facilities for research, education, and training.  The centre’s goal is to foster new and innovative ways to manage wastewater. Built to LEED Gold standards, the building warms through residual wastewater heat, uses rainwater for toilet flushing, and enables on-site stormwater management.

Houle designed and installed a complete DDC system for this centre. This included the integration of BACnet/ Modbus speed drives, power meters, heat pumps, lighting system, and air handler to the DDC.

Challenges
The design, which included rainwater harvesting and grey water system, had to be constructed to LEED standards. Construction had to be completed under a tight budget and schedule constraints.

Successes
Houle supplied technical and engineering help to assist with the design of the DDC controls.  The team successfully delivered a heat exchange system never tried before.
