The client’s objective was to create a modern, energy-efficient, and safe sports facility that ensures optimal indoor comfort for athletes and visitors year-round. The main focus was on integrating sustainable HVAC solutions, including a 160kW air-to-water heating system, heat recovery ventilation, smoke extraction, and cooling, ensuring efficiency, safety, and long-term operational reliability.

Challenge

One of the first and most important steps in installing a heat pump system was accurately calculating the heating and cooling loads of the entire sports facility. Determining the exact thermal demand for different areas (e.g., indoor courts, locker rooms, and spectator areas) required precise calculations and careful planning to ensure the heat pump system was correctly sized for the facility’s needs.

Solutions & applied technology

The Kiili sports hall project stands out for its high-performance Panasonic air-to-water heating system, which serves as the backbone of the building’s climate control. This 160 kW system is designed to maximize energy efficiency, sustainability, and heating precision, ensuring a comfortable indoor environment regardless of the season. The breakthrough lies in the dynamic operation of Panasonic’s heat pump technology, which intelligently adapts to demand, optimizing energy consumption while maintaining stable indoor temperatures. This reduces energy waste and lowers operational costs, making it an ideal solution for large facilities like sports halls. To optimize heating efficiency, the system is combined with underfloor and convector heating, ensuring even heat distribution and rapid response to temperature changes. Additionally, control by BMS allow optimizing operation and costs. This setup improves comfort for athletes and visitors while minimizing energy consumption.

The Kiili sports hall project significantly improved energy efficiency and reduced environmental impact by integrating a high-performance Panasonic air-to-water heating system. This 160 kW system (10x KIT-WXC16H9E8) operates with renewable energy, reducing reliance on fossil fuels and lowering CO₂ emissions. By combining underfloor and convector heating, the system ensures even heat distribution and minimizes energy waste, boosting long-term sustainability. Additionally, the heat recovery ventilation system reuses warm air, reducing heating demand and overall energy consumption. The intelligent heat pump technology dynamically adjusts to demand, reducing unnecessary energy consumption while maintaining ideal indoor temperatures. This resulted in lower utility bills, a faster return on investment (ROI), and improved long-term operational efficiency.

Control by BMS. Home Management Systems (BMS) allow centralized fully bi-directional monitoring and control of all the functioning parameters of all heat pumps, optimizing operation and costs. Modbus interface PAW-AW-MBS-H (Intesis) were used for this project. Units can be controller simultaneously by remote controller and the gateway.
