In the second article in a two part series, Stadium Director Gordon Banks guides us through the energy efficient measures that are in place at Allianz Park.
“As our aim is to manage a state-of-the-art sporting stadium here in NW4 that is sustainable, thus a number of procedures are in place that are conscious of the green surroundings, environmentally friendly and eliminating waste as and where we can” explained Banks.
“We’re zero [waste] to landfill and are recycling as much as possible”
“Around the stadium we have general waste and mixed recycling units,” Banks adds. “We’re going to have a compactor in the back of the stand, which we hope will be a recycling compactor, and we’re talking about anaerobic digestion in terms of our food waste.”
“Measures such as ground source heat pumps, Photo Voltaic panels, solar hot water, lighting controls, floodlights offering reduced light pollution, heat recovery, light energy lighting, rainwater harvesting and low water use sanitary ware and are a few examples of what we are doing to reduce energy consumption as much as possible.
“We’ve got a six month agreement in place with the energy providers, but it’s certainly something we would be willing to take a look at,” Banks says of switching to fully renewable power.
In addition to the solar array, behind the new stand 24 holes have been drilled 100 metres deep for a new ground-source heat pump system, which aims to provide heat and all the hot water in the building, generating “a really big saving“, Banks stated.
The stand has also been cladded in sustainable cedar, which along with special glazing ensures an impressive U thermal performance factor of 20.
Reusable and recycable materials were used in the construction wherever possible, with Saracens working hard to improve the biodiversity of the site. Green walls are being grown up the side of the stand, which improves insulation as well as biodiversity habitats, while a new swale and reed bed system has been incorporated to help drainage, and bird and bat boxes have been fitted.
“The relatively easy bit is building something that is sustainable,” he says. “But actually, if we didn’t manage it very sustainably then it would be a bit pointless”.
