The Efficiency Valuation Organization (EVO) publishes the International Performance Measurement and Verification Protocol (IPMVP) to increase investment in energy and water efficiency, demand management and renewable energy projects around the world. The IPMVP allows building owners, energy service companies, and financiers of energy efficiency projects to quantify the energy savings performance of energy conservation measures (ECMs). It provides an overview of current best practice techniques available for verifying savings from both traditionally funded and third-party-financed energy and water efficiency projects.

The IPMVP was recently revised, and is now in three volumes, available at http://www.evo-world.org/

 Volume I - Concepts and Options for Determining Energy and Water Savings (2009)

 Volume II - Indoor Environmental Quality Issues (2002)

Volume III - Applications

  • I – Concepts and Options for Determining Energy Savings in New Construction (2006)
  • II – Concepts and Practices for Determining Energy Savings in Renewable Energy Technologies Applications (2003)
