Measurement and verification

Intent

Provide for the ongoing accountability and optimization of building energy and water consumption performance over time.

Requirements

Install continuous metering equipment for the following end-uses:

• Lighting systems and controls
• Constant and variable motor loads
• Variable frequency drive (VFD) operation
• Chiller efficiency at variable loads (kW/ton)
• Cooling load
• Air and water economizer and heat recovery cycles
• Air distribution static pressures and ventilation air volumes
• Boiler efficiencies
• Building-related process energy systems and equipment
• Indoor water risers and outdoor irrigation systems

Develop a Measurement and Verification plan that incorporates the monitoring information from the above end-uses and is consistent with Option B, C or D of the 2001 International Performance Measurement & Verification Protocol (IPMVP) Volume I: Concepts and Options for Determining Energy and Water Savings.
