Aviva Stadium / Sustainability

 
 

The Aviva Stadium replaced the oldest international rugby ground in the world – Lansdowne Road stadium. The new stadium sits within the site boundaries of its predecessor which ensures that not only has the site usage remained the same but also it remains one of the most centrally located stadia in Europe, within walking distance of the city centre and served by a range of public transport options. It also acts as model stadium in terms of sustainability having won the 2011 Green Building of the Year, and the 2012 Green Entertainment and Leisure awards at the Irish Green Awards. The Aviva Stadium also claimed the ONCE award for Accessible Design at the 2010 World Architecture Festival.

The stadium’s form and mass are defined by the site and the adjoining neighborhoods, the North stand curves down to a single tier stand and is clad with a transparent façade in order to maximise natural daylight to adjacent properties. The façade and roof are comprised from light weight polycarbonate panels supported on a steel structure both materials can be recycled at the end of their lifespan. The translucent nature of both the roof and façade not only benefit the adjoining properties but also help to maximise natural lighting within the stadiums bowl resulting in a reduction of energy due to lower artificial lighting demands.

 


Energy efficiency resulting in carbon reductions is further enhanced through the use of:

 


Materials with low environmental impacts were specified throughout from water based resin flooring to timber used in joinery elements, however the material with the potential to have the largest impact due the volumes used was concrete. A ground granulated blast slag (GGBS) constituent was specified for use in all in-situ and precast elements. This not only saved approximately 4000 tCo2 in embodied energy if a more conventional concrete mix with a 100% portland cement was specified but also achieved a high quality finish.

Despite Ireland’s mild climate and abundance of rain, water shortages are frequently experienced making it essential to conserve one of our most precious natural resources – Water. The Aviva stadium utilises a number of water conservation measures such as waterless urinal bowls and troughs throughout the stadium, sensor taps and dual flush toilets. It is estimated that a saving of 400,000 liters of water is achieved through these measures throughout an average year in the stadium. Rainwater is harvested, treated and stored for use in the pitch irrigation system which has a capacity for 6 days irrigation.
