Kwantlen Polytechnic University Trade & Technology Centre Campus, BC (Canada)

Kwantlen University Building Automation

The Cloverdale campus covers three major building blocks that require monitoring and control, including classrooms, office areas, workshops and laboratories totaling 185,177 square feet.  Kwantlen wanted a cost effective building management system that will save energy from the date of installation

Kwantlen's energy management team commissioned Delta Controls, and their installation partner, ESC Automation to install an intelligent BAS system to provide for control and comprehensive monitoring of the following:

  • Natural ventilation
  • Heat recovery and radiant floor
  • Demand ventilation
  • Control exhaust systems
  • Motion sensors
  • Daylight sensors
  • High efficiency lighting system
  • Condensing boilers and security systems

The Building Automation System was embraced as a core area of focus to enhance facility improvements and achieve their environmental sustainability goals which contributed significantly to achieving the LEED Gold Certification.

Some of the key technologies installed included building controllers integrated with lighting occupancy sensors, isolation dampers for rooms with scheduled operating times, digital networked thermostats for precise control and feedback, occupancy sensors triggered by sound, in addition to movement, new building management system (BMS), control of exhaust systems, and awareness and training programs.

Interoperability is a key element of the Delta BAS, which helped integrate with third party products. The Delta platform is BACnet™ interoperable and operated from a single workstation. By incorporating the same core technology and operating software in HVAC and lighting, Kwantlen Polytechnic University’s Trade & Technology Centre is able to integrate and easily adapt to ever changing operational scenarios.

Resulting Efficiency Gains and Optimization

  • Annual Energy Savings of upto 45%; Annual savings in natural gas by upto 25%
  • Estimated reduction in GHG emissions by 20% over the next decade

The energy efficiency results have been very positive - The 2009 /10 APPA Energy Total Cost GSF/GSM with Purchased Utilities Report benchmarked Kwantlen’s energy cost as half of that of other higher education and public buildings.

The Physical Plant Manager Dan Brown believes that tighter integration with automation systems finds opportunities to more closely manage energy performance; which is why they continue to invest in automation by adding metering functions.  For example metering the main chiller plant will achieve better load management for demand billing by adjusting the demand profile to access savings, or monitoring the server room energy creep over time to help proactively identify anomalies.

Dan tracks energy intensity measures and his ethos is ‘measure what you can influence’.

The Cloverdale campus continues to provide stable energy performance, despite an increase in student volumes.  The university publishes its energy statistics and energy action plan on their website as part of their commitment to energy management.

Cost Savings

Operational cost savings across the campus locations as a result of the energy management program has equated to $2.7m CDN in the last ten years.  The square meter footprint of the all of the campuses has increased from approximately 80,000 to 10,000sq meters during that time yet electricity usage has fallen by about 9%.

When asked about this success Dan Brown says “it is not one thing we do it is everything from capitol renewal expense choices to cleaning contracts.” However he adds “the control system is the brains of the building and is integral to helping achieve energy savings”.
