A brief description of when and why the building energy consumption baseline was adopted:

2008 / 2009 academic year was the first year NSCC began documenting energy demand and tracking emissions in one centralized public location. By using this baseline comparing energy usage becomes easy, as this is the baseline used in the Annual Sustainability Report. The report can be found on NSCC’s sustainability webpage.


A brief description of any building temperature standards employed by the institution:

All of our campuses are controlled by their own central building automation system. The central building automation system controls the temperature according to the peak occupancy hours of the building. Winter temperatures are regulated to 20°C in occupied areas, and 16°C in unoccupied areas.


A brief description of any light emitting diode (LED) lighting employed by the institution:

Every NSCC campus has an application of LED lighting, whether it is the exterior light or various areas inside the buildings. At least one building on every campus contains LED lighting. Roughly 40% of Campus lighting is LED. It is estimated that 80%-100% of the lighting in the NSCC buildings are “high efficiency”.


A brief description of any occupancy and/or vacancy sensors employed by the institution:

Every NSCC campus across Nova Scotia has buildings that have motion sensor lights installed. For example, at the NSCC Waterfront campus all of the bathrooms have motion sensor lights in them. In areas without sensors many campuses regulate lights automatically using an automation systems, which will turn the lights off after peak hours, and keep lighting minimal during the summer.


A brief description of any passive solar heating employed by the institution:

Pilikan House at the Middleton Campus in Annapolis Valley was built facing South, allowing for optimum solar gain. The windows let in natural light which helps increase the home's ability to capture and store thermal energy in the form of heat. All new construction has passive solar heating taken into consideration.
The Centre for the Built Environment has a south facing solar wall, to feed heat into the HVAC system. Similarly, the Pictou Trades and Innovation Centre that is currently under construction will also utilize similar solar wall technology.


A brief description of any ground-source heat pumps employed by the institution:

Cumberland Campus in Springhill Nova Scotia employs a geothermal system, which uses heat from the underground mine shafts to heat a refrigeration shop. Waterfront campus in Dartmouth also has a ground source heat pump.
The Pictou Trades and Innovation (currently under construction) will obtain 60% of its heat through a geothermal system.


A brief description of any cogeneration technologies employed by the institution:

NSCC is currently working with a third party company "Bridgewater Renewable Energy Work" (BREW). BREW is currently working towards having a biomass energy plant constructed and operating at Lunenburg Campus in Bridgewater Nova Scotia.


A brief description of any building recommissioning or retrofit program employed by the institution:

NSCC strives to recommission its campuses every 5 years, recommissioning is currently in progress.


A brief description of any energy metering and management systems employed by the institution:

Every NSCC campus has a centralized energy management system. For example our Middleton Campus uses Honeywell’s Enterprise Buildings Integrator and our Lunenburg Campus uses Sieman’s Building automation System.

All Campuses energy demand is monitored using Smart Meters, and reviewed monthly via a web based software. Monthly reports on energy trends and recommendations for improvement are distributed to each campus.


A brief description of the institution's program to replace energy-consuming appliances, equipment and systems with high efficiency alternatives:

NSCC sustainability policy states that NSCC recognizes that one of the primary methods of exercising its commitment to sustainability is through its purchasing choices. When doing any purchasing, and replacement of equipment NSCC's policy is to chose products with low environmental impact.


A brief description of any energy-efficient landscape design initiatives employed by the institution:

NSCC chooses native vegetation thus reducing irrigation requirements and other energy intensive maintenance.


A brief description of any vending machine sensors, lightless machines, or LED-lit machines employed by the institution:

Many Campuses across the province utilize vending machine misers, these will detect the occupancy levels and temperature levels in the area. This allows lights in the machines to shut off when nobody is in the area, and limits the compressor cycles so the machines are not running when not required.
