In pursuit of lowering operating costs and increasing building performance, the Monterey Place Condominium Corporation investigated the costs and benefits of upgrading their existing boiler system at their facility in Saskatoon, SK. With this purpose in mind, Thurston Engineering Services was contracted to perform a Pre-Project Energy Audit and make application through NRCan's ecoENERGY program to obtain available incentives.
Service completion: 2010
Scope of services: Auditing, Retrofit Project Management, Ongoing Monitoring of Energy Use, Federal and Provincial Grant Application
Size: 51,594 sq.ft., 32 condominium units
Building system: Hot water radiators fed by hot water boiler; dedicated domestic hot water heaters
The building was constructed in the 1998 and contains 32 condominiums. General observations made during the energy audit included a well maintained, but inefficient non-condensing hot water boiler system. Natural gas consuming equipment consisted of one, 1,560 MBTU hot water boiler and two, 250 MBTU hot water heaters that were the original equipment for the building.
The non-condensing boiler and water heaters were replaced with three, Viessmann Vitoden WB2B condensing boilers and a 120-gallon domestic hot water storage tank. After the first full year of operation, the hot water heating system had a 37% reduction while the domestic hot water had a 61% reduction in consumption.
This yielded an overall 42% savings ($10,345) in natural gas consumption for the first full year of operation. Full federal and provincial incentives were obtained.
