Simple Ways to Find Energy Efficiencies in Buildings:
Change your Habits:
Manage your building's thermostats and make use of your window coverings. Close windows when the sun is making temperatures rise in your office. Alternatively, open window coverings to warm up a cold office - use sunlight as a heat source.
Be Transparent:
Post utility bills if possible. Let employees know how well they are doing at conserving energy every month by showing them the power bill in an internal company newsletter.
Commissioning Building Systems:
Commissioning ensures a building system is running as designed. Systems degrade over time, so they should be periodically re-tested. This should be done every 3-5 years.
