OBS rules may mean Velodrome blackout during Olympics

Natural lighting at Hopkins’ Velodrome, the bookie’s favourite to win the 2011 RIBA Stirling Prize, will be hidden away during the Olympic games

Rules on lux levels set out by the International Olympic Committee and the Olympic Broadcasting Service (OBS) insist glazing be covered during the broadcasting of Olympic cycling events with blackout blinds.

OBS is reportedly concerned that cameras will have difficulty in adjusting to different lighting conditions. LOCOG (the London Organising Committee of the Olympic and Paralympic Games) and Hopkins Architects believe this wouldn’t be a problem.
