LIGHTING HOSPITAL RETROFIT
For the hospital’s refit, the project team devised the IMI Pod, a prefabricated modular unit which offers storage as well as lighting and can be configured in a variety of ways ranging from single to six-bed options
As with all the settings, this can be
overridden by the nurse should the patient need to be left to sleep. Control is via two handsets, which account for the visual acuity and ability of the patient, and feature easily understood pictures – chair for visitor scene, book for reading. The pod is also future-proof. The
control system can potentially be linked to handheld devices using android or Apple systems and, while the sources are currently half LED and half fluorescent, that balance will shift to favour LEDs as they improve. By year three, it should be 100% LEDs,
solution. ‘If you just looked at this as lighting, then we would be more costly,’ says Bissell. ‘But we haven’t put everything into one light fitting, we’ve put it into a ward design. We’ve gone beyond the scope of the lighting. ‘What we said was, what if we design the

and by year seven it should be half LEDs and half OLEDs. It already cuts energy use by 30%, according to IMI. ‘Technically we have to show continuous improvement in energy efficiency and maintenance,’ says Bissell. IMI has been named as a group
one supplier for any future ward refurbishments, which will involve 26 wards over a seven-year period. The installation of a working four-bed bay by the end of this year will allow for patient feedback – two mock-ups have already provided staff reactions. The full refurbishment is scheduled to start in April/May 2012. ‘Huge amounts of interest’ have also
been shown by other UK and international hospitals, says Bissell. The real clincher for the concept is that it comes in at the same price as a traditional

patient environment as a complete solution and include the storage, and look at changing the angle of the beds – to give the patient a view or prevent them staring up the gown of the patient opposite, for
instance – and we do this offsite? Then as an offsite single product it’s the same cost as screwing everything to the wall, which is what you get now. ‘It is a huge leap of faith and it’s involved
a huge amount of trust, but everyone believes this needs to happen and it’s the right thing to do,’ concludes Bissell. ‘The point is this process gives you a
blank piece of paper and leads to better quality lighting than we currently have.’ CJ
ADVANTAGES OF THE IMI POD l Same investment as traditional build
l One-week reduced construction period per four-bed bay
l Energy consumption savings of 30% – existing lighting load: 4.2 kWh per day; 1515.5 kWh per year. Proposed lighting load: 2.7 kWh per day; 996.5 kWh per year
l Maintenance savings of 85% l Future-ready modular design Source: IMI
Forward Commitment Procurement (FCP)
Give the supply chain time to innovate: l Think ahead, signal long and medium-term
direction of travel to the market l Communicate forthcoming needs
and procurements in advance of formal procurement
Allow room for innovation: l Communicate needs in outcome terms – throw away the catalogue and state what
you want, not what you think is available or
affordable l Look for progressive improvements and future proofing
Invite feedback from the supply chain: l Market consultation allows requirements to be tested and problems ironed out in advance of procurement Source: BIS
