Bloomsbury Theatre’s energy savings

electricity usage is now down to less than 15 kWh a day; nearly seven times less

bloomsbury theatre

Sitting at the heart of UCL’s Bloomsbury campus, the 535-seat Bloomsbury Theatre is used by UCL students for 12 weeks a year, with a range of comedy, opera and music events for the remainder of the time. 

The existing incandescent lighting scheme at the Bloomsbury Theatre dated back to its opening in 1968. Although this lighting offered the warmth and dimming capability that the theatre needed, it had become a drain on energy and resources. The incandescent lamps ‘popped’ so often that the theatre maintenance staff spent an average of four hours a week changing the dead bulbs.

Previously, the theatre’s 114 incandescent lamps (drawing combined nearly 7kw) used up to almost 100kWh of electricity a day.

Now the theatre has replaced their incandescent lamps with 114 LED downlighters (combined around 1kW). Their electricity usage is now down to less than 15 kWh a day; nearly seven times less. The LEDs also have an average lifespan of 30,000 hours, so instead of spending 2-4 hours a week changing lamps, they haven’t had to replace any since.
