“There is no substitute for a comprehensive energy survey and analysis of all your firm’s energy-efficiency options, but if you “don’t do anything else” here are some simple, high “return on investment” equipment upgrades. These 12 “sure savers” include:

1) Turn off lights and equipment when not in use;

2) Buy ENERGY STAR labeled products;

3) Install lighting occupant sensors in proper locations;

4) Adjust lighting to actual needs — use free “daylighting”;

5) Tune-up HVAC system with annual maintenance contract;

6) Regularly change or clean HVAC filters;

7) Install a programmable HVAC thermostat;

8) Replace incandescent light bulbs with compact fluorescent lamps (CFLs), wherever appropriate;

9) Install LED (light-emitting diode) exit signs;

10) Control direct sun through windows;

11) Use fans; and

12) Plug air leaks with weatherstripping and caulking.” (p 4, Putting Energy Into Profits)
