In a recent Bachelor Thesis conducted at the University of Applied Sciences Graubünden, Switzerland, the economic and ecological ramifications of implementing electricity reduction measures in ice rinks were meticulously investigated. Titled "Measures for Electricity Reduction in Ice Rinks: Economic and Ecological Impacts," this thesis delved into the practical strategies aimed at mitigating energy consumption and its environmental footprint while considering the financial implications for ice rink operators.
Authored by Gianni Hertner, a Bachelor of Science student in Business Administration with a specialization in Entrepreneurship, this thesis explores the pressing need for sustainable practices in the ice rink industry. The study's primary focus was to identify and analyze various measures that could effectively reduce electricity usage in ice rinks without compromising operational efficiency or ice quality.
Throughout his research journey, Hertner received support from Jörgen Rogstam and EKA in the subject matter of energy consumption and utilization in ice rinks.
The research highlights four key areas crucial for sustainability in ice rinks: the implementation of natural refrigerants, heat recovery systems, energy-efficient practices, and the integration of renewable energy sources. By thoroughly examining each aspect and conducting a detailed analysis, the thesis provides actionable recommendations for immediate implementation, as well as long-term strategies to enhance energy efficiency and environmental sustainability.
Moreover, the thesis underscores the economic viability of these measures, emphasizing potential cost savings and long-term benefits for ice rink operators. By switching to renewable energy sources, optimizing operational practices, and investing in innovative technologies like CO2 refrigeration machines, ice rinks can significantly reduce their environmental impact while improving their bottom line.
This Bachelor Thesis serves as a valuable resource for ice rink operators, policymakers, and stakeholders interested in fostering sustainability within the industry. With practical insights and evidence-based recommendations, it offers a roadmap for achieving energy efficiency goals while advancing environmental stewardship in ice rink operations.
4 Keys Takeaways - Recommandations for Action
Implementation of Immediate Measures
It is important to implement immediate measures to adjust the ice thickness, ice temperature, and operating times of the ventilation/dehumidification in the ice rink. Operators and the ice master should jointly be responsible for monitoring and adjusting the optimal ice thickness and temperature based on external environmental factors. Additionally, the operating times of the ventilation and dehumidification systems should be controlled to operate only when necessary. This recommendation is supported by studies showing that targeted adjustment of these parameters can lead to energy savings without compromising ice quality.
