requirements. The ‘new’ ED will have HTM 03-compliant air exchange rates, i.e. six air changes / hour in general areas, and 10-15 air changes / hour in the ‘resus rooms’ and ‘Majors’ clinical rooms.”
Opportunity to bring in new technology Rob Few said the ED project would also be ‘a great opportunity to introduce new technology’, such as a new patient monitoring system that will afford consultants and other clinicians improved patient oversight, as well as enabling patients to talk to nurses direct. He said: “On all these schemes, we are aligning the M&E equipment with current HTM stipulations. To get to that point from where we were in the estate will be fantastic. Much of the existing estate was built in the 1980s, and the buildings were thus designed to previous HTM standards.” The associate director for Estates &
Facilities explained that his team is also overseeing a refurbishment of the first floor Maternity Unit at Macclesfield District General Hospital. He explained: “We are fitting new medical gases, LED lighting, ceilings, and flooring, and upgrading the unit to IPC requirements, with new washhandbasins, as well as new furniture.” Also fitted will be a new baby tagging system, while the electrical infrastructure on the ward will be upgraded.
Decarbonisation work Having by this point discussed quite a number of different built estate upgrading and improvement projects at Macclesfield District General Hospital, we next focused on the decarbonisation work either ongoing or planned. Rob Few explained: “The key element of this is a new air source heat pump here in Macclesfield, which will offset the gas used by our boilers,

generating heat by using electricity. The scheme as whole will offset our 2032 NHS England carbon reduction target, and obtaining the investment for our decarbonisation plans has been a huge positive.” Rob Few explained that the new £2 m
heat pump is being installed in a new Salix-funded Energy Centre, with its own transformer and electrical HV supply. He said: “The Energy Centre, which is currently being built, will be single-storey, but with a mezzanine above to house new chillers. The heat pump has already been craned in.
Energy Conservation Measures “As part of Energy Conservation Measures – which are part of our Trust Green Plan,” Rob Few continued, “we will also be upgrading our (Open Building Services) Building Management System, and
decarbonising our HSDU (Sterile Services Department) in the Service Centre on the first floor of the hospital here in Macclesfield. This will involve de-steaming the site, and installing electrical steam generators in the HSDU, which handles surgical instruments for all three hospitals, and is a significant carbon emitter.” He added that the two main gas boilers
at Macclesfield District General Hospital will be fitted with new burners, but with the heat pump in situ, will operate less frequently, as a ‘top-up’: “The air source heat pump will generate around 300 kW, and the site’s overall peak demand is around 1600 kW,” he explained. “We already have a CHP in place, with a 600 kW output, and Centrica has modified this as part of our decarbonisation work, fitting a new engine to make it run more efficiently.”
