Our Services

What they all have in common: scalability

We specialize in retrofit solutions that deploy broadly across your building portfolio. 

We also provide the capacity to deliver innovative projects through our turnkey model of “Assess-Fund-Retrofit-Verify.”

Retro-Commissioning

Low-cost projects with ROIs that far exceed your savings rate.

Buildings are complex. Many of them don’t run the way they were intended.

Trim Tab has a team of experts with design and operational experience in all your building’s major subsystems: heating, cooling, ventilation, hot water, lighting, and building envelope. 

We perform an in-field assessment to verify design requirements, identify maintenance and operation issues, and seek out energy efficiency opportunities. 

We do all this with an aim to lower operating costs, extend the life of your assets, and address concerns related to comfort and indoor air quality.

Once measures are identified and prioritized with the client, we return with the same tools and people to recommission those systems so they perform optimally.

We co-ordinate with utility programs to cover most of the upfront cost, and obtain additional rebates on the back end to offset individual projects.

Air Sealing

Draft control, smoke control, pest control, radon control.

“Seal it tight and ventilate it right” is a well-known adage in building science.

A poor air barrier is the root cause of many ills in rental housing:

  • high heat loss leading to higher utility bills
  • migration of smoke and odor between units
  • infiltration of pests in search of a food source
  • ingress of radon, a soil gas.
 
Air sealing is the unsung hero of retrofitting. Trim Tab does it better than anyone else because we make it a core competency. We combine traditional methods with advanced technologies such as AeroBarrier, and always show proof with a blower door.

Heat Pumps

Lower utility costs while adding central cooling.

Most rental housing is heated with inefficient boilers and electric baseboards. Most suites lack central air conditioning, or they rely on window units that often are improperly installed. As a result, the top floors of apartments swelter in the summer heat.

Enter heat pumps: 

  • They provide a highly efficient source of heating and cooling
  • They have the ability to operate over the full range of design temperatures.
  • They have the ability to dramatically lower hydro costs 

 

Trim Tab specializes in heat pump retrofits in apartments. This is multi-trade work that requires design and verification. Trim Tab handles the entire process to ensure it is done properly.
