Case study: Callendar House

Historic building meets modern technology

Callendar house, a  majestic 14th century heritage property set in the 170-acre Callendar Park, Falkirk, has played host to many eminent figures from the past, including Mary Queen of Scots and Bonnie Prince Charlie.

However, in August 2014, they were to invite a very different guest to their property: the LED lightbulb.

As part of a retrofit project with LEDHut, funded by Falkirk Council’s Sustainable Falkirk Capital Fund, Callendar House underwent a lighting transformation, seeing 540 LED Lumilife bulbs fitted across their vast estate.

Before the project began, an energy audit revealed that replacing the lighting in Callendar House’s main exhibition areas, conference rooms and corridors would cut energy consumption by up to 90%, as well as reducing the carbon footprint.

In total, 250 GU10 and MR16s were changed, as well as a mixture of 290 E14, E27, B15 and B22 LEDS for wall lights and chandeliers throughout.

£3,700 saved per-year

The transformation saw energy output reduced dramatically, from 19,850W to just 2,122W.

A key concern was whether LED lighting would compromise the ambience that was carefully created throughout the building. These fears were allayed thanks to the range of lighting solutions offered by LED Hut’s Lumilife range, which allowed the operations team to replicate the look and feel accurately.

Jon Cruickshank, facilities and operations assistant at Callendar House was pleased with the results: “After reaching numerous suppliers, we were very impressed with the LED Hut Trade site and its Lumilife range offered the exact LEDs we needed to match our existing fittings – including the house’s traditional chandeliers and wall lights”

“We were able to specify the same light output and colour combinations that we had before, whilst saving around 90% on our energy usage.”

“Setting up an account on the trade website and placing the initial order was very straightforward, and the new bulbs arrived the next day. We were able to fit the LEDs ourselves, replacing the existing bulbs like-for-like with no rewiring required. As a result, we have instantly cut our lighting scheme’s energy output by around 17,700W and we’re expecting this to translate into savings of more than £3,700 a year.”

Lighting solutions for every demand

Laura Dugdale, LED Hut Trade marketing manager, said: “The Callendar House project proves that LEDs are not just a high-performance, energy-efficient solution for modern projects. Thanks to the range of fittings available, they are suitable for a whole host of applications, including heritage retrofits like this one. The Lumilife range has provided Callendar House with the right mix of energy savings and lighting ambience, and has fitted so seamlessly with the unique historic atmosphere of the property. Not only will the new LED lighting scheme continue to set the scene for regular exhibitions and events, it will also deliver ongoing savings for many years to come – and is a significant step forward towards a more sustainable future for Callendar House.”
