Research on the contribution rate of photovoltaic power in indoor ice arenas across different climatic zones: A case study in China

With the increasing construction of ice arena facilities, addressing their energy consumption issues has become crucial, emphasizing the need for renewable energy utilization. This study aims to determine the contribution rate of photovoltaic (PV) power generation in indoor ice arenas across different climate zones in China and proposes corresponding PV application strategies. By modeling the vertical zoning above the ice arena, energy consumption in indoor ice arenas across six typical cities was simulated, calculating annual and monthly renewable energy contribution rates and proposing utilization strategies. The research reveals a growing proportion of cooling energy consumption due to climate warming, exceeding half of the total energy even in cold cities. Differences in energy consumption and renewable energy contribution rates among cities highlight the impact of local climate conditions. Favorable climates and abundant solar resources in some cities enable more energy-efficient ice arena construction, while high energy consumption and limited solar resources pose challenges in others. The study identifies seasonal variations in renewable energy contribution rates, emphasizing the need to optimize power generation seasonally. In colder cities, summer power generation is essential, while in hotter climates, winter power generation is more advantageous. This study provides insights for designing energy-efficient and sustainable ice arenas.
