A sustainable stadium for Heracles Almelo

It seems only a matter of time before the first stakes are driven into the ground for the new quarters of Heracles Almelo. Sustainability is the basic principle governing the building, furnishing and materials selection. The stadium will have the most advanced synthetic turf system available, including water buffering. As far as possible sustainable materials, including those from TenCate, will be used in the construction and other parts. 
Whatever the new stadium looks like, as far as main sponsor TenCate and Heracles Almelo are concerned the top priority is that it should be sustainable accommodation. Not only will again the most advanced synthetic turf system be installed, but as far as possible the club and builders also want to use sustainable (bearing and supporting) materials, such as geosynthetics and composites. What’s more, the stadium will be equipped with the latest resources and facilities when it comes to electrotechnics, energy consumption and climate control.

When it comes to making stadiums sustainable and improving safety, sustainable building materials, energy-neutral facilities, the problem of waste, and safety are among the aspects to be considered. Through using TenCate materials and through partnerships with regional companies such as Pentair, Wavin, Polyned and Pilkington, savings on water, energy and building materials are both functionally and aesthetically feasible. GreenSource, for instance, is a system based on a TenCate synthetic turf system and Pentair water filtration technology for the management of drinking water. The water inside the stadium is collected by synthetic pipe systems from Wavin, which are installed deep around the field. The purified water can be used as drinking and rinsing water and, even taking into account the required buffer of 180 m3 for the fire service, there is still sufficient water available.

As far as the roof construction is concerned, the thoughts of TenCate and partner Polyned are turning to thermoplastic composite materials: repeating roof units of 10 x 20 metres, in two models for straight sides and curves. These units of lightweight TenCate Cetex® would be welded together on site. Should such roofing prove too heavy, the UV-resistant geosynthetics and inherently flame-resistant fabrics from TenCate offer a real alternative. 
In this concept the actual roofing rests on 52 pillars, and a wind turbine on each pillar can generate energy. In addition a large surface area is covered with solar panels. Electric power can also be decentrally generated by a biogas-fired boiler (as guaranteed by the combined forces of Stork, Bronkhorst HiTech and HoST). Whether sufficient waste (animal and other fats) is available is now under investigation. The idea has also been floated of channelling hot water to the stadium and the nearby hospital in Almelo from the hot water system of AKZONobel in Hengelo, which for the time being has overcapacity.
Other options include high-efficiency and self-cleaning glass from Pilkington and biological paint from Van der Geest − the only paint in the world based on linseed oil. The USE Domotica system for the electronic supervision of supporter flows and a Thales monitoring system equipped with infrared cameras and image recognition software will handle the safety aspect.
