This has been updated and expanded several times since then and in 2001 IPMVP Inc. was formed as an independent non-profit corporation in order to include the international community.
It aims to provide a basis for demonstrating emission reduction and delivering enhanced environmental quality; also to provide a basis for negotiating the contractual terms to ensure that an energy efficiency project achieves or exceeds its goals of saving money and improving energy efficiency.
Savings are determined by field measurement of all key performance parameters which define the energy use of the ECM-affected system.
This approach is likely to require a regression analysis or similar to account for independent variables such as outdoor air temperature, for example.
While teams of energy engineers have managed IPMVP projects largely through Excel spreadsheets, recently there has been the shift towards online software tools and platforms.
The goal is to facilitate the import of independent variables such as heating and cooling degree days,[4] the creation of energy baseline, the identification of correlations and regression models for the automation of measurement and verification practices.
[7] Other tools emerge that allow easy production of adjustment models and more easily taking into account changes in static factors.
