Intent

To further ensure that the building systems function as designed, and that they continue to maintain energy performance over time.

Requirements

Option 1. Enhanced Commissioning (1–3 points)
Owner must designate an independent commissioning provider (CxP) during predesign or very early in the design phase.

PATH 1. ENHANCED COMMISSIONING FOR MEP SYSTEMS (2 POINTS)

• Comply with ANSI/ASHRAE/IES Standard 202-2024, Commissioning Process, for mechanical, electrical, plumbing, control, data center, process, building monitoring, and renewable energy systems.
• Comply with the following additional requirements:
  • During the design phase, attend at least two coordination/design meetings to discuss review comments and commissioning.
  • Prior to or during occupancy, review the training materials to confirm that they meet the training plan, and confirm that the training occurred.

AND/OR

PATH 2. ENHANCED COMMISSIONING FOR BUILDING ENCLOSURE (1 POINT)
Comply with all tasks and deliverables referenced with ASTM E2947-21a, "Standard Guide for Building Enclosure Commissioning," except Sections 7.2.4 and 7.4.3.

Comply with the following field-testing requirements:

• Building air leakage testing per ASTM E783, ASTM E779, ASTM E1186, or ASTM E3158.
• Water penetration testing per ASTM E1105 or AAMA 501.2.
• Infrared imaging per ASTM C1153 or ASTM C1060.

During occupancy, review the training materials to confirm that they meet the training requirements provided in the building enclosure commissioning (BECx) plan or specification, and confirm that the training occurred.

AND/OR

Option 2. Monitoring-Based Commissioning (MBCx) (1–2 points)

PATH 1. BASIC SOFTWARE (1 POINT)
Process and communications
Commit to implementing MBCx for a minimum of three years, through a contract with an MBCx provider or qualified monitoring-based commissioning provider (MBCxP) staff person. MBCx shall commence no later than building occupancy and shall be fully coordinated between the commissioning provider, facilities management, and MBCxP.

Develop a monitoring-based commissioning plan summarizing the process including all of the following:

• Roles and responsibilities
• Software technology description, including frequency and duration for trend monitoring
• Review and reporting criteria, including:
  • Training of facilities staff
  • Expeditious communication of major anomalies or faults identified to facilities staff
  • At least quarterly, MBCxP summary of anomalies and faults detected and communication with facilities staff to discuss and prioritize issues
  • At least annually, MBCxP summary reporting of trends, benchmarks, faults, energy savings opportunities, corrective actions taken, and planned actions
  • At least two MBCxP reviews of building systems, equipment, and operational controls

Energy information system
Provide a remotely accessible platform with software functionality to perform smart analytics and visually present all metered data referenced in EAp4: Energy Metering and Reporting.

Include the following functionality:

• Annual energy benchmarking of energy use intensities
• Comparison of energy consumption to the prior interval annually and monthly; for electric interval meters, daily and hourly
• For electric interval data, hourly load shape with comparisons
• Visualization and reporting of hourly electric submetered data

In addition, provide hourly monitoring and visualization of electric energy use for:

• Elevators, escalators, and/or moving walkways.
• Commercial kitchen equipment in spaces with more than 10 kW of rated capacity.
• Process equipment in spaces with more than 10 kW of rated capacity.

OR

PATH 2. ENHANCED SOFTWARE (2 POINTS)
Comply with Path 1 AND provide the following enhanced monitoring and software technology functionality:

• Fault detection and diagnostics (FDD) for projects with large HVAC or refrigeration capacity. For total project installed capacity of cooling, heating, or refrigeration systems exceeding 7,200 kBtu/hr (600 tons or 2,110 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
• Energy information system (EIS)
  • For major renovations and buildings less than 25,000 sq. ft., comply with ASHRAE 90.1, Section 8.4.3 requirements, for measurement devices in new buildings, without exceptions. Include visualization of this data per Path 1 requirements above and provide automated reporting of energy use anomalies.
• For all other buildings, include the following additional functionality for the EIS:
  • Automated reporting of energy use anomalies
  • Normalization of energy consumption
  • Greenhouse gas emissions reporting
