example, so there is always a role for the implementation of the facilities manage- ment. It’s just that when you’re study- ing the overall potential energy reduc- tion you probably want to take a more integrated, holistic project management approach,” he says. The process starts by pinpointing inef- ficiencies across the public areas of the centre’s 1.6m square feet of floor area. Then, with the help of technology com- pany, Sefaira, it will analyse the large amounts of data obtained through accu- rate monitoring.
Sefaira will then help gather enough of Bluewater’s consumption data to start “sequencing the changes in such a way that will deliver substantial savings for a significantly smaller capital outlay”. Sefaira has worked closely with the Bluewater team to design a programme of upgrades and improvements to unlock maximum savings. Mittermaier says this integrated, holistic way to enhance ener- gy efficiency is likely to eradicate the old approach and change the way facilities are managed.
“At the beginning of your strategy you might change your HVAC system. You may also do other work such as optimise

your sensors to be in line with the kind of light, which in turn has an impact on the heat, which therefore affects your building management system and at the end of all that you may realise that you need an HVAC system that is half the size of what you thought.
“So to avoid this you need to take a deeply integrated and cleverly sequenced
approach. This will involve running a very complex modelling strategy to come up with the right sequence with the right investment and this will funnel down to looking at whether it’s better to first change the lights or the cooling and heat- ing system”. And, he says, “we believe this will help us achieve a 50% carbon reduction.”
