ENERGY-P ADVANCED Äänekoski
“The experience gained in designing and building large and advanced technology air-supported balloons, make the textile a valid solution for covering entire football fields. These projects where the energy efficiency and functionality of the structure are combined with architecture, are a fertile ground for interesting projects by using durable textiles and advanced engineering solutions”.
This is the case of theair-supported balloon built in conjunction with the PoVe consortium for the town of Äänekoski
in Finland, where we – as Canobbio Textile – built a cover measuring 100.30 m x 60.30 m wide to cover the winter playing field of the town’s football team.
The permanent air-supported balloon was made using the innovative ENERGY-P ADVANTAGE technology developed in recent years. It consists of: two fully detached membranes measuring 40 cm and connected to each other with a tested and patented system of stamps and cables. Comparing the three types (Single membrane, Double membrane and Energy) – considering the same climatic conditions – it is clear that the DM allows to save 11% compared with the SM while the Energy solution allows to save 20%. Another advantage that can be obtained, compared with the DM, lies in the elimination of the thermal bridge along the perimeter of the pneumatic cushions; avoiding condensation and eliminating dispersions on the perimeter (doors and ground joint) allows to save by more than 49% as a whole.
Besides the two fully detached membranes, an internal membrane was tested and used with a special treatment which has two functions. In winter, the membrane allows to preserve the heat of the cover, given that it has a lower dispersion and save energy significantly. In summer it reduces radiation and the resulting internal overheating.
