A brief description of the institution's initiatives to shift individual attitudes and practices in regard to energy efficiency:
Zero Carbon Ambassadors Program
The opening of The Joyce Centre for Partnership & Innovation is an important opportunity to engage and educate Mohawk students to use the building in sustainable ways and contribute to the zero carbon goal. The Zero Carbon Ambassadors Program is a network of peer educators responsible for engaging others in creating a net zero Joyce Centre. Using peer-to-peer engagement strategies, student leaders will:
- Provide tours of the building,
- Provide information to questions about the building including key features and zero-carbon building design
- Engage students on energy and building usage
- Promote zero carbon and zero energy practices within the building
A brief description of energy use standards and controls employed by the institution:
Building Automation Systems, that control the mechanical, electrical and lighting systems based on established occupancy levels, are located in both the DBARC and the H-wing.
Across the college there are Daylight and occupancy sensors in the DBARC, and H-Wing as well as various classes rooms.
A brief description of Light Emitting Diode (LED) lighting and other energy-efficient lighting strategies employed by the institution:
The college is equipped with several outdoor solar and wind powered LED lights. Over the past few years there have been many LED retrofits around the college at both the Fennell and Stoney Creek campuses. In 2016, the entire A-wing building space lighting was upgraded to LED and occupancy sensors were installed .
A brief description of passive solar heating, geothermal systems, and related strategies employed by the institution:
Joyce Centre for Partnerships and Innovation. The Joyce Centre showcases leading edge environmental technologies that significantly reduce a building’s carbon emissions. The seven story building’s technology includes:
• A high-performance building envelop to maximize heating, cooling and natural light
• Solar panel arrays generating 721, 000 kWh/year
• A solar thermal array
• 28 geothermal wells
• A variable refrigerant flow heat pump system
• Storm water harvesting of up to 228,000 litres
• Sensor controlled LED lighting
• A green roof with extensive planted areas
• High-efficiency plumbing fixtures
The Centre was designed to exceed the requirements for energy harvesting and conservation and will serve as a living lab for students. Students will have access to every part of the building, from the penthouse to the basement and will be able to monitor real-time data on energy used and generated by the Joyce Centre.
Designed by McCallum Sather and B+H Architects, The Joyce Centre was created with the following in mind:
• A financial and energy budget
• Passive energy/free energy principles of building
o Thermal and performance elements carefully considered and optimized for interaction with local microclimate
o Building shape
o Orientation
o High performance windows
o External shading mechanisms
o High performance insulation
• Regional climate and geographical orientation
o Ex. Building faces west therefore architects built external shading mechanism

A brief description of the institution's initiatives to replace energy-consuming appliances, equipment, and systems with high efficiency alternatives:
Mohawk College received $10.8 million to support energy efficiency upgrades on campus including replacing an existing natural gas-fired boiler with and electrical boiler and upgrade two other natural gas-fired boilers. https://www.hamiltonnews.com/news-story/8319015-mohawk-college-gets-10-8-million-for-energy-retrofit-projects/
Using the SaveOnEnergy Program, Mohawk College has also completed LED lighting retrofit projects across the college include the A-Wing and E-Wing.
