McGILL ENERGY MANAGEMENT 2007-2008

• Creation of the energy saving committee, committee members:– André Aylwin - François Turcotte

– Alain Fournier - Hubert Marcil

– Michel Gauthier - Lyne Surprenant

– Claudia Bergeron, H.Q. - Richard Demers, GasMet.

• Implementation of an energy action plan as requested by the Education Ministry (MELS).

• Evaluation of several energy saving initiatives.

• Re-distribution of the energy consumption for each building at McGill.

• Energy saving project example (McLennan/Redpath Libraries).

• Realization of a pilot project at the James Administration building.

NINE STEPS ENERGY ACTION PLAN

1: Development and adoption of an action plan for the Ministry of Education, Leisure and Sports (MELS). (Done)

2: Assignment of responsibility for plan implementation. (Done)

3: Development of an energy plan for every building. (On going)

4: Determination of quantity of greenhouse-gas emissions for McGill energy production systems. (Done)

5: Target: By 2010, achieve a 12% reduction in energy intensity and 30% reduction in GHG emissions relative to 2002-2003. (Done)

6: Implementation of energy saving projects to achieve selected targets. (On Going)

7: Adoption of sustainability standards for the construction of new buildings or facilities. (On going)

8: Adoption of sustainability practices for the retrofit of facilities and their use by occupants. (On going)

9: Training program for McGill employees to promote sustainable practices. (To come)

WHAT CAN YOU DO

• Last person to leave the room turns the lights off.• Ensure door is fully closed entering/leaving a building.• Walk up or down the stairs when possible.• Lower the temperature a few degrees in the shower and

reduce shower time.• Avoid opening windows as a temperature control mechanism.• Search for the energy star label for electric devices.• Get involved, share and explore ideas and become an

ambassador of sustainability/energy saving.

Examples of some students projects:• Campus energy mapping• Solid biomass cogeneration
