Improving efficiency in ice hockey arenas
This article, from the ASHRAE Journal, describes energy efficiency for arenas in Quebec. The analysis of energy efficiency for arenas should consider the building as a whole with all its mechanical systems and architectural systems. Because a refrigeration load exists for the ice rink along with other needs for heating, the refrigeration system should act as a heat pump to supplement the heating requirements. For many arenas, proper heat recovery could lead to a 50% annual energy savings.
