Foster’s staff has had specialized experience and training in energy saving implementations.
We can work with you to determine the potential for cost savings for your business or home.

The methods used to accomplish energy savings are very individualized. A building survey is often a good beginning. Making slight changes to an existing system can sometimes lead to significant cost savings.
Some examples of this are:

• Controlling space temperatures so that they are at an optimum level for energy savings while still comfortable for the occupants.  Temperatures can often be set back during unoccupied times.
• Ventilating the occupied spaces with a proper amount of outdoor fresh air, but not more outdoor air than is needed.
• Closing outdoor air dampers, turning off air handling units, and turning off exhaust air fans when the affected spaces are unoccupied.
• Using cool outdoor air for free cooling during time when the outdoor air is suitable for cooling.  This can be done by adding an economizer damper/control system.  Or if there is already and economizer system in place, it is important to get it working properly.
• Replacing older equipment with new, more efficient equipment.

Replacing older equipment with new, more efficient equipment that will save energy such as: boilers, furnaces, air conditioners, heat pumps, pumps, motors, and water heaters. Installing variable frequency drives on motors that do not need to run at full speed all of the time can save energy.

Installing new, additional systems, components, or controls can save energy, including:
• Heat pumps
- Air-source heat pumps
- Geothermal heat pumps
- Water heating heat pumps
• Heat pumps that can redistribute heat inside a building. These systems can cool some areas while heating other areas by depositing the heat that is removed from the areas to be cooled into the areas to be heated.
• Solar heating systems (solar thermal systems)
• Energy / heat recovery ventilators
• Control systems
- Controls that limit peak electrical demand
- More precise control of temperatures.
