Fact Sheets
CanmetENERGY has prepared a series of fact sheets that describe the impact of various energy efficiency measures on the energy consumption and GHG emissions of a typical arena (reference arena). The results that show the benefits of these different measures were generated by CanmetENERGY using DOE software models.
Set of fact sheets (PDF, 2.6 MB)
This document comprises all 9 fact sheets intended to arenas stakeholders and more specifically to consultants and managers of arenas.
This document describes the main features of a typical arena that was used by CanmetENERGY to evaluate the impact of energy efficiency measures applicable to this type of building.
Influence of ice rink ceiling type (PDF, 404 KB)
This fact sheet proposes improvements to the ceiling of an ice rink. The impact resulting from the implementation of those improvements on energy consumption and GHG emissions of the arena are discussed.
Secondary coolant and pumping power relation (PDF, 362 KB)
This fact sheet proposes improvements to the refrigeration system, and more specifically to the brine circuit. The impact resulting from the implementation of those improvements on energy consumption and GHG emissions of the arena are presented.
Optimizing refrigeration condensing temperature (PDF, 303 KB)
This fact sheet proposes improvements to the operation of an ice rink refrigeration system. Benefits of modulating the condensing temperature (floating head) are specifically presented. The impact resulting from the implementation of those improvements on energy consumption and GHG emissions of the arena are presented.
Reduction of lighting intensity in the ice rink (PDF, 150 KB)
