This section of the guidance outlines the approaches that can be taken to support the process Authorities can use in the identification and implementation of carbon reduction opportunities within buildings to achieve NZ for Operational Energy. The core of the guidance focuses on operational energy carbon reduction but there will undoubtably be other opportunities for broader carbon reduction in PPP assets and projects. This is true particularly on some of the earlier PPP projects where the scope of the facilities management offering includes an extensive range of non-building related services typically, waste, water, travel, fleet and food all of which are influenceable by the procuring public body and the Project Co. It is recommended that Authorities when using this guidance should do so in conjunction with their wider carbon footprint reduction strategies to limit the environmental impact of their service in the broader sense.
