Your Postcards questions answered: New Energy Efficient Lighting

Written by Brendan from Great Ormond Street Hospital on 11th May 2015

At the recent Postcard Event, new lighting came out as the most popular suggestion for making the Trust more sustainable. We agree that it offers the Trust a huge potential to reduce its energy demand, save the Trust money and lower the Trust's carbon footprint.

The Estates Department has identified numerous lighting retrofit projects to replace old inefficient lights with the latest energy efficient LEDs and control systems.

The first phase of these projects is now complete and we are sure you will have noticed some of them. The stairwells in VCB and Southwood have had LED lights fitted that include colourful halo's to help visitors identify which building they are in and to make the stairwells more attractive and interesting.

We have also updated the corridor lights in the x-ray department to bespoke LED fittings which fit the existing light fittings. These lights all incorporate presence sensors and wireless technology so that when the department is out-of-hours, the lights will dim down to 10%. The wireless technology means that when one fitting senses movement it will send a signal and all of the lights in that corridor will return to full output.

Finally, we have fitted LED panels in the Rainforest Department which have made the department brighter and reduced the heat gain in this space which historically suffered from overheating.

These three projects are expected to save the Trust £6,000 and 36 tonnes of CO2 per year.

We are also pressing ahead with replacing lights in OBW, Nurses Home, Southwood and Barclay House.

The biggest saving that can be made from lighting though is to turn them off when they are not needed. So please be vigilant and turn off any lights you see that have been left on.

This is great to see, any idea how much energy this will end up saving?
