Introduction
International Standard is designed to be used by all the project stakeholders that aim to quantifytechnical and financial barriers in the measurement calculation and verification for energy saving the energy savings over a specific period in the new projects or retrofit projects. It could reduce theprojects.
M&V could be selected under different project scenarios. It is intended as a set of principles guidance mon understanding of M&V on project level is established by outlining how calculation methods forand methods for M&V of energy savings that can be applied to a broad variety of projects.
have a clear and correct understanding of the energy performance of project.
In this International Standard energy savings are determined by paring measured calculated orsimulated energy consumption before and after and/or with and without implementation of a project and making suitable adjustments for changes in relevant variables (routine adjustment) or suitableadjustments for changes in static factors (non-routine adjustment) and therefore energy savings arethe difference between the adjusted energy baseline and the reporting period energy consumption.
This International Standard can be used by any interested party in order to apply M&V to the reporting of energy savings results
