EVO began as IPMVP, a committee of volunteers who came together under a US Department of Energy initiative to develop an international M&V protocol that would help determine energy savings from energy efficiency projects in a consistent and reliable manner.

In the 1990s, investments in energy efficiency projects were less than expected due to the high uncertainty associated with future energy savings. This uncertainty arose, in part, from multiple and often inconsistent Measurement and Verification protocols. These inconsistencies resulted in a patchwork of engineering approaches to efficiency installations and measurement of savings.

In 1994, Greg Kats and Art Rosenfeld at the US Department of Energy and Steve Kromer at Lawrence Berkeley National Laboratory, initiated an effort to establish international consensus on methods to determine energy/water efficiency savings and thus promote third-party investment in energy efficiency projects. This initiative pulled together energy efficiency experts from North America in the beginning and later from all over the world. One of the larger goals of this initiative was to help create a secondary market for energy efficiency investments by developing a consistent set of M&V options that can be applied to a range of energy efficiency measures in a uniform manner resulting in reliable savings over the term of the project.

The voluntary efforts of these international experts resulted in the publication of the North American Energy Measurement and Verification Protocol - the NEMVP in 1996. The NEMVP established a framework for defining standard industry practice. The methods were named Options A, B and C.

In 1997, an updated version of the protocol was published and was renamed the International Performance Measurement and Verification Protocol (IPMVP) to reflect the international nature of the protocol. As water was recognized as a critical resource on par with energy, M&V for water efficiency projects was included for the first time in this version.
While the first version had three M&V Options, a new M&V Option D was included in the second version to recognize the industry practice of using energy simulation tools to determine energy savings, which are then verified by measuring energy use and calibrating the simulation model. The four M&V Options A through D have since become industy standard.

The third version, published in January 2001, and called IPMVP Volume I: Concepts and Options for Determining Energy Savings clarified the definition of Option A by removing any ambiguity relating to the use of stipulated values in the engineering calculations/models. IPMVP Volume II: Concepts and Practices for Improving Indoor Environmental Quality, was published concurrently with Volume I.

In September 2001, the Protocol Committee of the IPMVP (called Executive Committee at that time) formed a non-profit organization IPMVP Inc. (deriving its name from the flagship product) to maintain and update existing content and develop new content where IPMVP can add significant value.

In 2002, IPMVP Inc., in conjunction with the Association of Energy Engineers (AEE), announced the launch of the Certified Measurement & Verification Professional (CMVP) programin an effort to raise the professional standards and improve the practice of those engaged in measurement & verification.

In 2004 the Board of IPMVP Inc. voted to change the name of the non-profit corporation to the Efficiency Valuation Organization (EVO) to reflect its expanded mission. Additional program areas now include the International Energy Efficiency Finance Protocol (IEEFP) an the International Program Evaluation Protocl (IPEP).

2005 saw the Board increase from six members representing two countries to 11 members from six countries. As the Board has increased in size, so the scope of EVO's international community has grown.

In 2006, EVO was proud to launch its Subscriber Services to help support a global base of knowledge in the field of resource efficiency M&V, as we understand that building an international community is critical to the global promotion of the efficient use of natural resources.

In 2007 IPMVP Volume I has been updated and released in English and French. EVO launched its new website with EVO documents, industry news, resources and discussion forums for online collaboration with colleagues from around the world. There is a special section in French where the French edition of IPMVP 2007 Vol. I can be downloaded.
