Scottish Futures Trust has developed an 'Energy Conservation Measures (ECM) Whole Life Cost Tool' designed to assist public sector partners managing operational PPP projects to make informed decisions to optimise a built asset's NZ performance where formal NZ changes or variations are being considered.
It is worth noting that the refences to Energy Conservation Measures fall under the same banner as Decarbonisation Options and when implemented, reduce energy demand, optimise energy efficiency, and/or deploy low and zero carbon technologies for Operational Energy. Further details can be found in Section 7.17 - Net Zero Business Case / Investment Models with the links to both the ECM appraisal tool and user guide included in Appendix 2.
The appraisal tool provides a consistent method of comparing ECM outcomes where an Authority is considering NZ changes or variations in existing operational PPP projects. It is both a qualitative and quantitative process that looks at the energy conservation outcomes in costs and relative savings over the remaining period of the PPP contractual period. The appraisal tool promotes the analysis of whole life outcomes across three assessment criteria: commercial; environmental performance and environmental savings against a business-as-usual baseline.
