Mount Allison is continually looking for ways to reduce its environmental footprint.

A summary of energy-conscious initiatives and projects the University has undertaken, or is in the process of reviewing and implementing, is listed below.


Completed projects

Residences

  • Major residence renovations have included installing energy efficient features such as low flow, dual flush, LED lighting, insulation of exterior walls, roof replacements, new windows, etc. Renovations have taken place in the following residences:  
    • Campbell Hall (2004)
    • Bennett House (2012)
    • Bigelow House (2013)
    • Thornton House (2016)
    • Windsor Hall (2019)
  • Eco-rep program established to improve energy efficiency and energy conservation awareness
  • Dump & Donate program established for year-end move-out in residences to reduce waste
  • LED lighting has been installed throughout the residence system
  • C3 campaign is conducted each year to help raise awareness of and reduce energy consumption
  • Residence furniture is sourced locally and many items are made with recycled material

Dining hall

  • An emphasis on local food purchases — 40 per cent comes from New Brunswick, PEI, and Nova Scotia
  • Bulk purchases of food to reduce packaging waste
  • Cooking oil is cleaned and reused resulting in a 50 per cent reduction in purchase of oil
  • Established a station in Jennings that is never touched by meat — 25 per cent of students are vegetarian or vegan
  • Introduced tray-less dining and a scraping station, which has reduced post-consumer waste by 44 per cent
  • All food waste at Jennings is composted
  • A new dishwasher has been installed that uses 50 per cent less water
  • The wood-fired pizza oven replaced an energy-heavy electric oven
  • Ventilation and lighting upgrades have reduced energy use
  • Added variable speed drives and cooking-level controls to the dining hall kitchen-hood exhaust system to limit fan power usage and fresh-air tempering when no, or low-load cooking, is taking place

Carpentry, trades, and grounds

  • Reduced carbon footprint by switching from fossil-fueled trucks to electric utility vehicles
  • Electric utility vehicles are equipped with solar panel charging systems
  • Switched to environmentally-friendly chemicals for lubricants and graffiti removal
  • Right-sized grounds equipment to eliminate unnecessary large trucks

Energy efficiency

  • Transitioned to occupancy sensors from standard on/off light switching
  • Transitioned to LED lighting technology from fluorescent, incandescent, and other lighting
  • Transitioned to variable speed drive fans and motors in ventilation systems
  • Implementing insulation repair/addition work throughout the steam tunnels and mechanical rooms to mitigate wasteful energy losses from energy transfer piping
  • Boiler plant improvements:
    • Converted fuels from bunker oil to natural gas
    • Converted to computerized combustion controls to increase boiler efficiency
    • Converted boiler feed and condensate return pumps to variable speed
    • Installed a small boiler specifically for summer loads, to avoid running the larger boilers unnecessarily
  • Optimization of lab/fume-hood exhaust system in Barclay Building
  • Addition of heat recovery in buildings with exhaust systems running more than 14 hours per day (e.g. Windsor Hall, Campbell Hall)

Projects under evaluation or in the process of being implemented

Snow and ice management

  • Improving annual snow and ice management equipment and processes with the implementation of a brining solution and equipment to reduce the amount of salt used on campus and align us with environmental best practices

Energy metering/dashboards

  • Implementing individual building and campus-wide energy metering (steam, water, and power) to proactively identify energy consumption anomalies, allowing the campus to identify issues with systems/operations prior to excessive energy waste taking place
  • Reviewing/implementing “load-shedding” and building start-stop programming in order to minimize electrical load peaks on campus, thus reducing the NB Power demand charges whenever possible (planned for after power meters are installed)
  • Implementing “Energy Dashboards” across campus for social awareness as it relates to energy/water usage

Energy efficiency

  • Replacing any remaining fluorescent/HID lighting with LED equivalents
  • Implementing insulation repair/addition work throughout the steam tunnels and mechanical rooms to mitigate wasteful energy losses from energy transfer piping
  • Boiler plant improvements:
    • Employing more variable speed drives on boiler fans, etc. and adding additional computerized combustion controls and operating controls to further enhance efficiencies
    • Reviewing the option of the addition of a renewable-energy boiler option using wood chips
     

Mechanical/electrical system improvements

  • Replacing constant speed pumps with new variable-speed controlled pumps to reduce wasteful mechanical pumping power when not required
  • Implementing/optimizing night-setback controls sequences in buildings to reduce building mechanical/electrical systems run-time during unoccupied times, holidays, snow-days, etc.
  • Implementing/optimizing building heating water temperature controls to minimize pump run-time and minimize steam usage while still providing comfortable temperatures across campus (with the goal of reducing heating water temperatures as much as is practical)
  • Reviewing the option of adding exhaust-air heat recovery to the Barclay lab exhaust fans to recover waste energy and preheat make-up air
