In a major part of the redesign of the capital ahead of the London Olympic Games, Uponor and its specialist indoor climate division, velta, were tasked with designing the plumbing and climate control system of the Velodrome – and providing the right conditions for world records.

Given the sheer scale of construction throughout the Olympic Village, the scale of the task facing Uponor and velta when they were asked to create a climate system that could help break Olympic records was enormous. In the case of the Velodrome track in particular, the technology had to be selected, installed and finished to an extremely high standard in a tight time-scale.

To meet the requirements of the International Association of Sports and Leisure Facilities, velta and Uponor needed to provide optimum conditions for cyclists from across the globe to set new records. This meant ensuring pinpoint levels of accuracy through carefully selected heating systems and precisely controlled air temperatures.

The Velodrome’s flooring technology requirements were relatively straightforward. The application of an embedded underfloor heating system was seen as key, as its natural flexibility allows for easy installation and superior performance in almost any domestic or commercial environment.

The velta-designed underfloor heating system offered the ideal solution in terms of climate control, using a radiant system of heat to maintain optimal climate conditions in each section of the stadium.

Within the Velodrome, the internal space required a temperature of 19°C to 21°C across the in-field arena, in order to take into account


the higher core body temperature of the cyclists. The area is in the region of 12m to 15m in size. However, the ‘occupied zone’, is just 2m wide. This was the area which required highly accurate heating levels to aid optimal performance of the athletes.

The radiant nature of underfloor heating meant Uponor and velta were able to factor in the expected radiant heat from the athletes and keep air resistance to a minimum.

The formatting of the sports flooring was dictated by the International Association of Sports and Leisure Facilities, based on environmental and science studies and informed by Sir Chris Hoy. Working closely with them and the design teams, a Uponor pipe system was installed in the floor to meet these requirements. With the exception of concrete, all of the products installed were from Uponor.

All of the distribution mains from primary plant equipment were comprised of Uponor’s Multi-Layer Composite Pipe (MLCP), press fittings and modular fittings covering Cold Water Service (CWS), Hot Water Service (HWS) and Low Temperature Hot Water (LTHW).

With all of the benefits of copper and none of the disadvantages, MLCP enabled a quick installation, allowing the build and the construction to be completed on time. Water-tight, and with dimensions of up to four inches, the MLCP system enabled the use of a wide range of pipe sizes to suit each area of the build. The modular
