Using these energy saving tips can make a difference in the amount of energy you use and money you save. Take a few minutes and learn about steps you can take, as well as practical information and advice you can put in place to start saving today.



​​Whether you have a small family business or a large commercial facility occupying hundreds of thousands of square feet, you can save energy and dollars by following some simple guidelines:

  1. ​Select high efficiency equipment when replacing worn out devices
  2. Maintain your existing equipment with scheduled maintenance.
  3. Establish an automated schedule for the operation of equipment.

Heating and cooling​

During Houston’s extreme summer heat, it’s essential to keep your HVAC equipment running properly.  Regularly scheduled maintenance should include replacing or cleaning filters and coils.  Large commercial facilities will typically have a central plant with complex operation and schedules.  Make sure your equipment is scheduled and sequenced properly. 

There is no excuse for running the entire cooling system during the middle of the night if only a skeleton crew is working.  Limit night time HVAC operation to zoned or smaller units. 

Ensure that your system cannot simultaneously heat and cool, as that wastes energy and dollars. 

Adjust dampers to use only the necessary amount of outside air to stay within local code requirements to maintain good air quality. 

If you have an Energy Management System (EMS), make sure the temperature set-points and schedules are accurate; a tiny error in programming can cost thousands of dollars annually.

Office Equipment​​​

Whenever possible, turn off any equipment that is not in use.  Many devices have built-in energy saving features to automatically shut down if not used after a preset time period.  Look for ENERGY STAR ratings when purchasing replacement equipment, to lower energy usage.


Replace conventional lighting (incandescent, or HID) with high efficiency lamps such as LEDs, which are becoming more generally accepted in the workplace and for outdoor lighting.  LEDs contribute less heat with more light output, and have extremely long life.  This lessens the heat load on your cooling equipment and lowers your maintenance costs.  LEDs use a quarter of the energy of conventional lighting and are available in many styles and sizes.
