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

The 2008/2009 academic year was the first year NSCC began documenting energy demand and tracking emissions for each Campus in one centralized public location. This is the baseline used in the Annual Sustainability Report. The report can be found on NSCC’s sustainability webpage: https://www.nscc.ca/about_nscc/sustainability/index.asp


Source-site ratio for imported electricity:
2

Total energy consumption per unit of floor area:
Site energy Source energy
Performance year 0.06 MMBtu / GSF 0.09 MMBtu / GSF
Baseline year 0.08 MMBtu / GSF 0.11 MMBtu / GSF

Percentage reduction in total source energy consumption per unit of floor area from baseline:
19.85

A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:

Sustainability has been embedded in the workplace culture at NSCC for over a decade. Sustainability is noted as a component of NSCC Strategic Plan during employee orientation. Awareness campaigns are regularly implemented for various sustainability initiatives focused on energy, both at individual campuses to address specific issues, as well as College-wide projects. Each campus has a sustainability committee that facilitate awareness campaigns and promote awareness about energy consumption at NSCC. Our sustainability team publishes an annual sustainability report that covers energy consumption as a performance metric at each campus in the province and creates action items for each fiscal year.


A brief description of energy use standards and controls 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 Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:

NSCC has been pursuing large-scale changeover from conventional light bulbs to LEDs over the past several years. Most of our lighting is now LED, both for exterior and interior spaces. It is estimated that 80%-100% of the lighting in the NSCC buildings are high-efficiency. Now the implementation focuses on replacing unique and difficult to source fixtures.


A brief description of passive solar heating, geothermal systems, and related strategies 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 at Ivany Campus has a south-facing solar wall, to feed heat into the HVAC system. Similarly, the Pictou Trades and Innovation Centre that was completed in 2017 also has a south-facing solar wall, as well as a geothermal system for building heating and cooling, and a solar hot water system that pre-heats all domestic hot water in the building.

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

NSCC have completed ASHRAE Level 2 energy audits at all Campuses within the last five years. The most recent audits were completed at Luenenburg, Pictou, Truro and Marconi Campuses in 2019. We have also completed retro-commissioning studies at nine of our campuses in 2019. Between the capital suggestions in the energy audits, and the low-cost/no-cost suggestions in the retro-commissioning studies, NSCC Facilities were able to prepare Energy Management Plans for all campuses, which outline all potential energy-related projects, their associated costs and timeline for completion, as well as overall impact on NSCC's GHG emissions.
