ASHRAE's Guideline 14-2002 for Measurement of Energy and Demand Savings: How to Determine What Was Really Saved by the Retrofit
Year: 2005
Type: article
Abstract: In the Fall of 2002 ASHRAE published Guideline 14-2002 to fill a need for a standard set of energy (and demand) savings calculation procedures.Guideline 14-2002 is intended to be a guideline that provides a minimum acceptable level of performance in the measurement of energy and demand savings from energy management projects applied to residential, commercial or industrial buildings.Such measurements can serve as the basis for commercial transactions between Energy Service Companies (ESCOs) and their customers, or other energy conservation providers that rely on energy savings as the basis for repayment of the costs of the retrofit.When applied properly, ASHRAE Guideline 14-2002 is expected to provide adequate assurance for the payment of services by allowing for well-specified measurement methods that provide reasonably accurate savings calculations.ASHRAE Guideline 14-2002 may also be used by governments to calculate pollution reductions from energy efficiency activities.Since Guideline 14-2002 is intended to be applied to an individual building, or a few buildings served by a utility meter, large scale utility energy conservation programs, such as those involving statistical sampling, are not addressed by Guideline 14-2002.Furthermore, metering standards and procedures for calculating savings from modifications to major industrial process loads are also not covered.This paper presents an updated 1 overview of the measurement methods contained in ASHRAE Guideline 14-2002, including a discussion about how they were developed, and their intended relationship with other national protocols for measuring savings from energy conservation programs, such as the USDOE's International Performance Measurement and Verification Protocols (IPMVP).
