Tisdale Regional Office

Lighting
The following table provides descriptions of the existing and proposed lighting conditions for different areas of the facility.

Furnace Control – Night Setback
Overview
The Tisdale Regional Office has four residential furnaces that ventilate the facility. Each furnace is controlled by a thermostat which is not capable of being programmed. By updating the controller and implementing a night setback strategy, significant savings can be achieved through reduced fan energy and natural gas usage.

Scope
Programmable thermostats will be installed and programmed to setback the setpoint temperature to 18 C during the un-occupied hours between 5:00pm and 7:00am

Electric Heater Control
Overview
The Tisdale Regional Office has several electric heaters providing supplemental heat to perimeter offices and entrances. None of the heaters are currently scheduled. By updating the controller and implementing a night setback strategy, significant savings can be achieved through reduced electricity.

Scope
Programmable thermostats will be installed and programmed to setback the setpoint temperatures to 18 C during the un-occupied hours between 5:00pm and 7:00am

Hot Water Temperature
Overview
The Tisdale Regional Office has its Domestic Hot Water (DHW) supplied by a single gas-fired hot water heater located in a mechanical space. During the audit the temperature measured at 152 f at the tap which is far hotter than necessary especially for a facility with no kitchen or laundry facilities. Reducing the DHW temperature will result in natural gas savings through decreased heating requirements and improved water heater efficiency.

Scope
The temperature adjustment on the existing hot water heating will be adjusted so that the water temperature at the tap is approximately 120

Parking Plug Control
Overview
Approximately 21 existing duplex parking plug receptacles are not presently controlled and are occupied approximately 40% during winter months. By implementing controls on these the power delivered to the plugs will be cycled based on outside temperature achieving both electricity consumption and demand savings while maintaining necessary power to the plugs so that users are able to start their vehicles. Time and temperature control will be installed. Plugs will be energized on at temperatures below -30C, alternate in at least 2-banks at 20 minute intervals at temperatures between -15C and -30C, and be off at temperatures above -15C. The lot will function as above to accommodate 24/7 function of the facility. Electrical savings will result from reduced energy consumption and reduced electrical demand.

Scope
IPLC controllers will be installed to replace 21 duplex receptacles and programmed to cycle 40% of the time when the temperature is between -5C and -15C, 70% of the time between -15C and -25C and 100% of the time when the temperature is -25C or colder.

Building Envelope Sealing
Overview
An investigation to upgrade the current conditions of the building envelope was conducted by CANAM Building Envelope Specialist. The results of this investigation have uncovered several areas where the building envelope can be upgraded in order to reduce heating costs. Most of the areas where improvements may be made within the confines of the performance contract involve low cost sealing of identified cracks around doorways.

Scope
The scope of work detailed by CANAM recommends the installation of weather stripping and sweeps at 3 exterior doors.
