Leiden has acquired a new ice hall and indoor swimming pool at De Vliet, together under one roof. 

The new ice rink is a sustainable replacement for the ice rink on Vondellaan. And the swimming pool is a sustainable replacement for the Vijf Meibad.

The building is 'off the gas' and will be 100% CO₂ neutral. The ice hall is even energy-neutral. This makes it one of the most sustainable sports complexes in the Netherlands. The residual heat from the ice rink is used to heat the swimming water. The roof of the new swimming pool and ice rink will be filled with solar panels.

Buitink Technology has delivered and installed the lowE acoustic stretch ceilings for the new building De Vliet.
 
The ceiling consists of 12 stretched ceiling cloths made of Soltis-Feel 88 LowE by Serge Ferrari. This acoustically open and thus sound-permeable cloth has an aluminum coating on one side with an emissivity of only 0,45 (''standard'' cloths usually have an emissivity of 0.90 or higher). The total ceiling area is about 875 m².

Above the ceiling cloths, Buitink Technology mounted a sound-absorbing acoustic wool with a thickness of 45 mm with a sound absorption coefficient AlphaW of 0,65. Naglam and reverberation of sound through the ceiling is thus prevented.

Engineering

Advantages

In summary, an acoustic LowE stretch ceiling from Buitink Technology has the following advantages.

• Energy efficiency: Low emissivity means that a material emits less energy in the form of infrared radiation. With a low emissivity value of 0.45 (compared to standard values of 0.90 or higher), the stretch ceiling reflects more infrared radiation than it emits. This means that heat that would normally rise from the ice rink and be lost is reflected back, keeping the ice cooler and requiring less energy to keep it frozen. This contributes to the energy efficiency of the complex.
• Cost savings: Less energy to keep the ice frozen means lower operating costs for the ice rink. Since the residual heat from the ice rink is also used to heat the swimming water, it makes smart use of available energy, further reducing operational costs.
•  Acoustic benefits: The stretch ceiling is not only energy-efficient but also acoustically absorbent. This means that the sound produced in the skating hall (e.g. by skaters, music, announcements) is absorbed and not reflected, which ensures better sound quality in the hall and less disturbance to users. The sound absorption coefficient AlphaW of 0.65 indicates that the ceiling absorbs a significant part of the sound.
• Sustainability: The complex is 100% CO2-neutral and the ice rink is even energy-neutral. The use of a LowE ceiling,in combination with other sustainable technologies such as solar panels, contributes to the overall sustainability of the building, which is in line with wider sustainability targets in the Netherlands.

In short, the LowE stretch ceiling above the ice skating rink contributes to a more energy-efficient, cost-effective and comfortable environment for both users and managers of the complex.
