KINECTRICS Extensive Laboratory Facilities

• Main Building constructed in early 1960s
• Constant Volume System with Terminal Reheat
  (electric)
• Started energy efficiency program in 1990s

Efficiency Improvement at Kipling

• SUPPLY TEMPERATURE RESET
• Constant Volume system with Constant Air Supply
  temperature - 13 C all year round
• Reprogrammed Control system to reset to 18 C in
  winter
• Savings of 60,000 per year in reheat
• Reduced humidification load
• Cost - 0 - programming done by operator
• Improved comfort in building

7
Efficiency Improvement at Kipling

• OVERHEATING PROBLEM IN SHOULDER SEASON
• Building suffered high temperatures on warm days
  in spring before chiller startup
• Economisers found to be closing on outdoor
  temperature rise even when chiller not operating
• Reprogrammed control system to keep economizers
  open when chiller not operating
• Delayed need for chiller start-up

8
Efficiency Improvement at Kipling

• ECONOMISER CONTROL
• Economisers closed to minimum ventilation
  position when outdoor air temperature above 18 C.
• Found them closing and chiller operating on sunny
  days when temperature only 10C
• Outdoor sensor reading 8 C higher than ambient
  due to solar radiation
• Shielded sensor required to eliminate problem

9
Efficiency Improvement at Kipling

• VARIABLE SPEED DRIVE RETROFIT
• Pilot project carried out to install VSDs on
  supply and return fans to reduce flow at nights
  and weekends.
• Potential one year payback
• Had problem with trip of supply fan due to power
  quality problem
• Steam humidifier kept operating even though no
  supply airflow
• Found that safety switches for airflow and high
  humidity sensing had been installed in return air
  duct.

10
Other Experiences

• New building with state-of-art HVAC system found
  to have high electricity bills.
• Building control system not set up to log
  electricity uses even though instrumentation
  installed.
• After setup of logs, found that chiller was
  running in January, without knowledge of
  operator.
• System needed recommissioning to eliminate
  problem.

11
Other Experiences

• New building with state-of-art HVAC and control
  system found to have high electricity bills.
• Lighting controls not working properly for ice
  rink area - operating on medium level when set to
  low.
• Estimated savings of 2000 per year.

SUMMARY

• Savings can be achieved in older buildings by
  reprogramming of controls and by checking that
  equipment is operating properly.
• Newer buildings can also have problems.
• Operators need to be able to understand systems.
