Commercial kitchens continue to be significant water and energy users and their carbon footprint on a business can be considerable. This new and expanded edition of Energy efficiency in commercial kitchens provides updated advice for designers, installers and operators of these facilities in all areas of business and industry on how to minimise their consumption, thereby realising efficiencies in both carbon emissions and operating costs. It has been prepared by a range of industry experts with real-world experience, with the aim of providing practical recommendations that can be applied to all commercial food service facilities, regardless of size.
