Energy efficiency upgrades – heating boilers
Institutional facilities and commercial buildings account for one-eighth of the energy used in Canada. A large majority of schools in Canada were built before 1980, therefore presenting an opportunity to investigate energy-efficient improvements. One of the areas that will help in the reduction of energy costs is efficiency gained through new technology in boiler design and operation.
It is reported that school energy costs represent the largest operating expense behind salaries, and directly affects the health of students and school personnel, which is why it is considered a strategic area to Energy savings is unquestionably the main driver when deciding to review measure. operational design of existing equipment in schools.

tenance requirements. It is our position that when looking at an overall operation of a facility, the lasting product has to be able to stand the test of time.
Some of the examples of this approach include:
In 2017, CustomAir completed Photo by Bright Photography. a boiler retrofit for an elementary school on the coast that was experiencing problems with their domestic hot water and heating/cooling system. The existing boiler was not to capacity, their energy bills were significantly higher, and they had no built-in redundancy if a failure was to occur. The job was completed on time and on budget resulting in a 25 per cent savings in gas consumption rate, and the school was able to pay back their investments in the first nine months with maximum rebates.
In 2019, CustomAir was able to maintain the full operation of a transit facility in the middle of winter and install a high-efficiency boiler system that not only qualified for maximum rebates, but eliminated the need for emergency repairs to the existing boiler plant.
