00:00I'm Paul Marshall, I'm the leader for West Sussex County Council and I'm very proud today
00:09to be here in Storrington Library launching one of the 14 buildings that we've been working
00:17on in terms of decarbonisation. Really key because it's about our journey that we've
00:24made for 2030 to be a net zero organisation. Climate change is important, it's important
00:30locally, it's important nationally and we've all got our part to play and as a county council
00:37we have a big footprint within this and it's important that we not only lead by example
00:43but help support our communities through this journey as well. I'm Darragh Casey,
00:48I'm Energy Services Manager here at West Sussex County Council. So we're looking at the new
00:52air source heat pumps that are providing renewable heat to Storrington Library. Air
00:57source heat pumps are one of the more efficient ways of generating the heat we need to keep our
01:03buildings warm and comfortable. So heat pumps work on the basic principle that there is dispersed
01:08heat in the air all around us. Air source heat pumps are essentially there to take that heat
01:14from the air and then they compress it and then they draw out the heat by compressing the air
01:21and then once they've drawn that out they are able to then put that into the radiators and into
01:26the distribution system that are heating our buildings. So essentially we're taking the free
01:30heat that's all around us, we're just concentrating that and then we're making use of it. So the heat
01:36pumps are terrific by themselves but they really work well when you've got a very efficient way of
01:41distributing that heat and getting it into the spaces we need. So we've coupled up this technology
01:47with some fan coil radiators. So these are a bit like normal radiators but supercharged.
01:52They're a very effective way of delivering the heat to the communal areas of a library or any
01:57other spaces like that. But I think the important thing to note is that the systems that are creating
02:03that heat, generating the heat for us to make a comfortable environment, they can only do that
02:08when you've got a good kind of tight envelope within which you can actually use and retain
02:14that heat. So along with the heating system upgrades that we've done here we've actually put
02:18in quite a lot of work around the insulation and new windows and doors and there's a fabulous
02:23skylight in the middle of the library which has been completely upgraded as well.
