Simply making sure the building systems are running as designed is called commissioning. It is an essential part of building construction and beacuse systems wear down over time, they need to be checked.
Such commissioning pays huge dividens a 15 percent reduction in energy use at a cost of just 27 cents per square foot for a payback of less than 9 months claims the Department of energy.
This process entails an analysis and a tune-up and usually requires the services of an energy auditor.
These systems also have to be maintained and recommissioned every 3-5 years. If you are renting, ask your landlord when the last time the building was commissioned.
Along with this process is the basics of preventative maintenance. Take a look around at light bulbs etc and set aside specific times to address the replacement of bulbs etc. Fluorescent bulbs degrade over time and fixtures with burned out bulbs draw power.
