City of Camrose Encana Arena Boiler Upgrade

OVERVIEW

As part of the Action Centre’s Recreation Energy Conservation Program, the city of Camrose completed a one-for-one replacement of three (3) mid-efficiency boilers with high efficiency condensing boilers operating in parallel to meet facility heating requirements.

The project was commissioned in May 2021.

APPROACH

This newly installed system will help to reduce the costs of heating the water used to resurface the ice as well as the As a community recreation facility, natural gas use is mainly attributed to space heating, ventilation, and air conditioning (HVAC), and domestic hot water (DHW). Conditioned space is heated both by the boiler-driven hydronic system and direct fired air handling units. The existing mid-efficient boilers with an AFUE of 86% were upgraded to higher efficiency 1.5 MBTU/hr condensing boilers with an AFUE of 95% that decreases the natural gas required to heat the facility.

RESULTS

The replacement resulted in a reduction of 34 tCO₂/year and an energy cost savings of $4,175/year. The project resulted in a 9% GHG reduction from the existing system and 1% reduction facility-wide from the baseline.

“The original boilers were aging and were very inefficient, and maintenance costs were rising to keep them running. It was time for them to be replaced with something more efficient and maintenance friendly. It was an opportune time for collaboration. We used ATCO Infrastructure Services to do the engineering study, documentation, provide the project plan and implementation to the MCCAC so we could get approval for the project.”
