Extracted Content

  • Normalization of energy consumption

  • Automated reporting of energy use anomalies

  • Greenhouse gas emissions reporting

  • Hourly metering and visualization of electricity for the following, if applicable:

o On-site electricity generation

o HVAC or refrigeration equipment with thermal energy capacity exceeding 900,000

Btu/hr (264 kW, 75 tons), or with rated fan power exceeding 75 hp (56 kW)

o Electricity use for process equipment with thermal energy capacity exceeding

900,000 Btu/hr (264 kW, 75 tons)

o Commercial kitchen equipment in spaces with more than 25 kW of rated capacity

o Process equipment in spaces with more than 25 kW of rated capacity

FDD for projects with large HVAC and refrigeration capacity For total project installed capacity of either cooling systems, heating systems, or refrigeration systems exceeding 7,200 kBtu/hr (600 tons or 2110 kW), provide a remotely accessible FDD system that addresses at least 60% weighted by capacity of:

  • Air-handling equipment AND

  • Large hydronic or commercial refrigeration equipment (chillers, boilers, etc.).

The FDD system must include the following functionality:

  • Perform smart analytics and visually present FDD data

  • Direct link from reported fault to view relevant trend data

  • Fault sorting and filtering

  • Exporting of fault reports (summary reports and detailed individual faults)

  • Data historian capable of storing critical trend data for at least three years

REQUIREMENTS EXPLAINED

The credit rewards projects that provide retro-commissioning (RCx) or implement monitoringbased commissioning (MBCx) in the building operations.

Option 1. Retro-Commissioning

Retro-commissioning (RCx) is an energy performance assessment that ensures systems function as originally intended.

Teams pursuing this option must complete RCx efforts, from the engagement phase through hand-off, for an RCxP process concluding no more than three years before the end of the 12
