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

The building energy baselines are chosen in accordance with the timing of the energy projects. All buildings have undergone energy projects and the baselines are chosen the year prior to the energy projects. The energy projects are tracked (measured and verified annually) and reported annually to the Board of Governors. This is all accomplished with the oversight of the Energy Management Committee.

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

Over the past few years, UNB Sustainability continues the Residence Energy Challenge. Over the period of one week, residences compete against one another to see who can save the most energy through energy efficiency practices. This competition helps shift students' perspectives of energy and their usage.

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

In July 2017 LED retrofit was carried out in the Facilities Management building whereby the T8, Compact Fluorescent bulbs and exterior High Pressure Sodium lights were replaced by LED alternatives. The payback period for this is 2.8 years. The old system was using up 12.7 kW per year which was costing around $5,700 to the university. With the new system installed the energy consumption of the building is now more than halved. The new electrical load is 5.4 kW per year which now costs $2,300.
In 2017 and 2018, UNB has completed LED retrofits to 10 other buildings on campus with similar savings results as Facilities Management.


A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:

Our newest building (Kinesiology) uses Earth Tube technology, an innovative technology that helps conserve energy required to heat and cool the building. The Earth Tube system consists of 8 underground tubes, buried below the frost line where temperature remains relatively constant. The steel cylinders above ground take in fresh air and the 8 tubes preheat (for winter) or precool (for summer) the entire fresh air requirement entering the building.
If the temperature is -15 degrees Celsius outside, by the time the air moves through the tubes underground to the back of the building, in conjunction with the heat recovery systems, the HVAC systems only need to add 0-2 degrees Celsius to the air in order to meet the 19-degree Celsius minimum room temperature. Therefore, UNB is getting 30-31 degrees for free.
Some of the heating and cooling energy for the Kinesiology building is reject energy from the connected Richard J. Currie Centre building. This energy sharing is permitted by two 10,000 gallon thermal storage tanks, visible to occupants through a mechanical room window in the Kinesiology building.
This energy sharing provides more efficiency to Currie and in turn conserves energy Kinesiology would otherwise have to output.
