Panasonic heating and cooling system for a multifunctional glass hall
Tetovo. North Macedonia
2025
When the investor began developing a new multifunctional hall for weddings and banquets, the goal was to create an elegant, fully glazed space that would offer maximum comfort to guests throughout the year. With a capacity of up to 400 people and architecture featuring large glass surfaces, air conditioning and thermal load control were high on the priority list. All roof and façade surfaces were made of glass with a thin reflective layer and motorized blinds that reduce solar heat gain.
Challenge
The main challenge was managing solar heat gain through the glass surfaces and ensuring a comfortable microclimate during events with a large number of guests. The average solar radiation exposure is around 200 W/m², which creates significant thermal load during summer months, even though most events are held at night when cooling needs are lower. Thermal calculations indicated a cooling requirement of 250 kW (with blinds lowered) and heating up to 180 kW during cold winter nights.
Solutions & applied technology
To ensure optimal comfort and energy efficiency, a solution combining Panasonic Rooftop units and Big PACi technology was selected. The system was designed to cover all functional areas of the facility:
-
2 × Panasonic Rooftop units, each 80 kW (total 160 kW)
Model: ECOi-RT C/H R410A, P-RTE0080H.EHG4 -
2 × Big PACi units, each 25 kW (total 50 kW)
Indoor: S-1014PF3E (2×), Outdoor: U-250PZH4E8 (1×) -
1 × Big PACi air curtain, 25 kW (currently being installed)
-
1 × Big PACi ducted unit for the kitchen, 25 kW
Outdoor: U-250PZH4E8, Indoor: S-250PE4E -
Multi-split systems for offices and auxiliary spaces
-
Kitchen ventilation system with variable frequency
(3,000–7,000 m³/h exhaust, 4,000 m³/h fresh air)
Excellent Performance and User Satisfaction
During testing, the systems demonstrated excellent performance and uniform air distribution using Jet Diffusers, enabling stable temperatures and a high level of comfort even at full hall capacity.
The project successfully combined technical sophistication, aesthetics, and energy efficiency, confirming Panasonic technology as the ideal solution for modern facilities with high demands for comfort and sustainability.
Green Impact of the project
This approach allows for optimized cooling capacity while reducing environmental impact, maintaining maximum visitor comfort. To preserve positive pressure in the main hall, rooftop units operate with 5–20% fresh air intake. During extremely hot days, this percentage is reduced to 0% to maintain cooling efficiency.
