UCalgary is a Canadian post-secondary leader in carbon emissions reductions.
As a signatory to the 2015 Paris Agreement, Canada committed to reducing greenhouse gases (GHG) by 30 per cent across the country by 2030 in an effort to help reduce global carbon emissions. The University of Calgary surpassed the 2030 target more than a decade ahead of time, attaining a GHG reduction of over 30 per cent across the institution since 2008.
Guided by the University of Calgary’s Climate Action Plan and the Institutional Sustainability Strategy (ISS) and its framework on Sustainability in Administration and Operations, UCalgary is striving to attain net-carbon neutrality by 2050 through being a Canadian post-secondary leader in energy efficiency and healthy, high performance green buildings.
Cogeneration System: Combined Heat and Power
UCalgary’s Central Heating and Cooling Plant’s Cogeneration system has reduced institutional GHG emissions by more than 60,000 metric tonnes each year since 2011.
UCalgary is shifting towards a cleaner and greener energy supply by generating our own renewable energy with on-site photovoltaic (PV) arrays.
Existing Buildings: Utility Reduction Program
To date, the Utility Reduction Program (URPr) has reduced UCalgary’s energy consumption by ~13,000 tonnes and generated ~$1,500,000 in cost savings.
Projects within the program are designed to bring aging infrastructure up to more energy efficient standards with a focus on mechanical upgrades, lighting retrofits, installation of energy recovery systems, as well as upgrades to the district energy distribution system. URPr examines buildings across all campuses and selects and implements projects based on their potential to improve building energy efficiency and reduce energy wastage.
The URPr investments into the building controls enable improved indoor environmental air quality by tracking ventilation rates within the laboratory spaces to ensure they are meeting the operation requirements of the space. In addition, demand control ventilation improves indoor air quality by allowing the ventilation system to adjust for increased times of building and space occupancy by tracking interior CO2 in spaces and increasing fresh air delivery when required.
Energy Demand Management Plan
In 2020, UCalgary engaged in developing an Energy Demand Management Plan (EDMP). The EDMP is a strategic document dedicated to improving existing building energy performance. A supporting document to the 2019 CAP, the EDMP’s identifies engagement, operational, reporting and technological advancement opportunities that will enable the institution to reach its 50% GHG emission reduction target by 2030. The EDMP prioritizes efforts on energy intensive buildings by identifying, screening and implementing energy improvement projects across the institution’s top energy users. Proposed initiatives include the Utility Reduction Program (URPr), deep energy retrofits, and energy optimization and operational improvements. These programs will use data-driven decision making processes to improve institutional energy performance, reduce GHG missions and avoid utility costs, thereby creating more sustainable and energy-efficient campuses. Inspired by best practices in energy management, including the internationally recognized ISO 50001 standard, the EDMP offers impactful recommendations to unite people, technology and processes and align them with the university’s strategic vision for sustainability.
UCalgary continues to take meaningful actions towards reducing its overall energy consumption. In conjunction to the EDMP, the university is working hard to ensure sufficient resources are available for the campus community to develop an understanding of ways they can reduce energy consumption.
New Buildings: Green Building Program
With 14 Leadership in Energy and Environmental Design (LEED) certified projects, and 4 registered projects currently underway, UCalgary is a Canadian leader in high performance green buildings. Find out how the redeveloped MacKimmie Tower is a high-performance, net-zero carbon building and one of the first projects striving for certification with the Canada Green Building Council’s Zero Carbon Building Standard.
Each year, UCalgary’s Green Building Program reduces
- Electricity consumption by more than 30,000,000 kWh.
- Natural gas usage by more than 72,000 GJ.
- Main campus cooling requirements by more than 98,000 GJ.
- Main campus heating requirements by more than 90,000 GJ.
Collectively, this reduces GHG emissions by approximately 14,000 tonnes annually.
