Measurement and verification procedures for energy efficiency investments
Measurement and verification procedures for energy efficiency investments
This deliverable addresses how one can determine the performance of buildings and energy improvement measures through the EN-TRACK platform. This deliverable does not choose a singular solution, instead hybridising automated and industry-standard manual approaches. This deliverable also gives a view of the resultant services from these implementations. The document describes the limitations and opportunities inherent within automated and manual measurement and verification (M&V) methods provided through the EN-TRACK platform. It is important to note that full M&V procedures are nuanced, and case-sensitive, and should be completed by an accredited professional where the outputs are going to inform key contracts, financing or service agreements. The deliverable describes the importance of wide-ranging data capture for these services. As such, it is proposed that the platform enables both automated synthesis of M&V outcomes (providing low transaction costs but lower data quality and fewer data features); alongside the manual input of M&V information, supported by automated data sufficiency checks, proposed guidance, and preliminary suggestions of specific IPMVP protocols. These two pathways are described in depth in Sections 5-6 with key supporting documentation, such as graphical process flows, presented in the Appendix. The deliverable then considers how best to integrate the latest modelling approaches, proposing methods for the selection of preliminary modelling approaches using industry standard model assessment metrics such as Mean Bias Error and the Coefficient of Variation (Root Mean Squared Error). The deliverable also discusses novel methods for the measurement and verification of Non- Energy Benefits through the COMBI and MBenefits approaches developed in partnership with the European Union. Decision trees and surveys for the selection of these approaches are provided alongside quantified increases in project value associated with specific non-energy benefits. The deliverable concludes with descriptions aiding the implementation of the above services.
