Reducing heating and cooling in spaces that are not used for long periods, like stairwells and unused spaces and turning off fans when the building is unoccupied can increase energy savings for your building.

Affordability

Reducing the amount of energy used to heat or cool parts of your building that are either unused or used only for short periods can be an easy and affordable way to control energy costs.

What you need to know

  • Reduce heating and cooling spaces used only for short periods. If possible, reduce temperature or shut off heating in vestibules, stairwells, lobbies and unused spaces.
  • To reduce cooling energy, shut off all unnecessary lights, cooking equipment and office equipment.
  • When the building is unoccupied, turn off exhaust fans in washrooms and kitchens with a timer. Also shut off outdoor air dampers and the supply air fan one hour prior to the end of occupancy.

FAQ

Most of our employees and visitors use the elevator so our stairwells are seldom used. Can we turn off heating and cooling in these areas?
Yes. Reducing the temperature or shutting off heating in vestibules, stairwells, lobbies and other unused spaces is a great way to reduce energy spending.

Occasionally an employee will come into the building on a weekend. Can we still shut off fans in the washrooms and kitchen?
Educate your employees about your energy management plan to ensure they understand and buy into your program for energy savings. They will then know what to expect on weekends or other times when the building is usually unoccupied.
