Energy-efficiency isn’t just for newer buildings. With today’s new materials and protocols, even hundred-year-old buildings can reap huge benefits in financial and energy savings while still keeping their aesthetic charm.

Retro-commissioning can produce significant energy cost savings by improving the way an already existing building operates. The majority of buildings that were state-of-the art when they were built, naturally become outdated over time and slowly fall behind newer buildings in energy-saving and comfort features that keep their values high.

ECOterra Energy Consulting retro-commissions focus on diagnostic testing first then improving occupancy comfort and energy savings by implementing maintenance and operational improvements in your building to ensure that all systems continue to work well together and have optimal performance over time.

ECOterra Energy Consulting | Retro-Commissioning

Here are some retro-commissioning opportunities ECOterra Energy  commonly finds during a building assessment that can be addressed through a retro-commissioning project:

  • Systems that simultaneously heat and cool

  • Equipment or lighting that is on when it may not need to be

  • Equipment or pipes that are hot or cold when they should not be

  • Unusual flow noises at valves or mechanical noises

  • Equipment that cycles too quickly.

  • Economizers which need repair or adjustment—potential problems include frozen dampers, broken or disconnected linkages, improper control settings and malfunctioning actuators and sensors

  • Pumps with throttled discharges

  • Improper building pressurization (either negative or positive). In otherwords, doors that stand open or are difficult to get open

  • Variable-frequency drives that operate at unnecessarily high speeds or operate at a constant speed even though the load being served should vary

If you assumed your historic or older building could never be made energy-efficient, call ECOterra Energy Consulting and we will surprise you with how many options are available to improve the energy performance in your structure.

Almost every energy-saving protocol that we practice can be retro-commissioned into an existing building by ECOterra Energy Consulting, drastically improving the building’s performance, savings, comfort and aesthetics.
