Nationwide Building Society was working to improve the energy efficiency of over the local branches sited around the country. Savacontrols were retrofitted to existing air conditioning units, heat pumps, refrigeration and air handling units to reduce their electricity consumption without affecting performance in any way. A trial installation on four Nationwide branches with both single and three phase heat pumps was commissioned.

Following these successful results, the first phase of the roll out across the branch network started, with the first 59 being completed to program. The second phase, a further 160 branches, was completed and Nationwide’s intention is for the program to continue in annual tranches across their entire branch network.
