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 (1–2 points)
Owner must designate an independent commissioning provider (CxP) during predesign or very early in the design phase.
PATH 1. 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 E71105 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 BECx plan or specification, and confirm that the training occurred.
OR
PATH 2. ENHANCED COMMISSIONING FOR BUILDING ENCLOSURE AND MEP SYSTEMS (2 POINTS)
Comply with Path 1, AND:
- Comply with ANSI/ASHRAE/IES Standard 202-2024, Commissioning Process, for mechanical, electrical, plumbing, control, data center, process, building monitoring, and renewable energy systems.
- Provide commissioning for components installed within the project scope of work. For any systems or controls that require future interconnection with tenant systems, provide templates for future commissioning of these interconnections that address the most likely tenant interconnection scenarios in the systems manual and tenant guidelines. At a minimum, provide these templates for design review checks, functional tests, and systems manual addenda.
- The CxP must comply with the following additional requirements:
- Attend at least two coordination meetings during the design phase and at least four milestone meetings during the construction phase to discuss review comments and commissioning.
- Provide an ongoing commissioning plan.
- During occupancy, review the training materials to confirm that they meet the training plan, and confirm that the training occurred.
AND/OR
Option 2. Monitoring-Based Commissioning (MBCx) (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, tenants, and MBCxP.
Develop a monitoring-based commissioning plan summarizing the process including all 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
AND
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, and to be expandable to include all tenant 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, and for electric interval meters, daily and hourly
- For electric interval data, hourly load shape with comparisons
- Visualization and reporting of hourly electric submetered data
- For tenant spaces > 10,000 sq. ft. (930 sq. m.), tenant portal with capability to provide visualization and reporting of:
- Base building data for shared systems serving the tenants and
- Tenant electricity energy use (excluding shared systems)
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.
What does it cost?
Cost estimates for this credit
On each BD+C v4 credit, LEEDuser offers the wisdom of a team of architects, engineers, cost estimators, and LEED experts with hundreds of LEED projects between then. They analyzed the sustainable design strategies associated with each LEED credit, but also to assign actual costs to those strategies.
Our tab contains overall cost guidance, notes on what “soft costs” to expect, and a strategy-by-strategy breakdown of what to consider and what it might cost, in percentage premiums, actual costs, or both.
This information is also available in a full PDF download in The Cost of LEED v4 report.
