Abstract
There is a great need of energy in ice hockey arenas. They are complex buildings with a great
and various need of cool, heat, hot water, ventilation and dehumidification. It is of great
importance to have both a qualified machinery and a skilful personnel. That was the purpose
of an educational project in order to develop of the competence of the personnel of ice hockey
arenas in the county of Västernorrland.
The objective was to get an increased understanding of the connection between various places
of use and be able to optimise the energy balance of the ice hockey arenas in a better way.
There are eighteen ice hockey arenas in county of Västernorrland. The halves of them are
owned by the municipalities and the rest by sport associations. Sixty-nine representatives of
eleven arenas participated in the project.
The project started with a conference targeted to the responsible personnel of the arenas.
After that followed one day each at every arena as follows:
? General theory of the use of energy in ice hockey arenas
? Overall inspection and analysis of the existing equipment and need of energy.
? Information and exchange of knowledge
? Survey of energy and cost effective measures
The annual use of energy in ten arenas was 11 076 MWh, the year 2 000.
9 790 MWh was electricity, 1 086 MWh district heating and 200 MWh fossil fuels.
The potential for efficiency is estimated to be 27 % or 3008 MWh, of that is 1837 MWh
electricity, 971 MWh district heating and 200 MWh fossil fuels. A survey of energy efficient
measures for ice hockey arenas is made within the project.
