Requirements

Establishment

Evaluate the current performance of the project building against the performance specifications in the current facilities requirements and the operations and maintenance plan. Identify the systems and components in the facility to be investigated and analyzed as part of the existing building commissioning or energy auditing process. Provide a breakdown of estimated resource use for each of these systems.
Option 1. Existing building commissioning
Develop an existing building commissioning plan to effectively inventory and evaluate specific opportunities within the systems being analyzed. The commissioning plan must include the following:
  • updated current facilities requirements;
  • the commissioning team members and their roles and responsibilities during the commissioning process;
  • a description of the approach for identifying and analyzing facility improvement opportunities;
  • the process for reviewing and prioritizing identified opportunities with the owner and developing an implementation plan;
  • the format and content of the eventual deliverables from the commissioning process; and
  • the proposed schedule.
Option 2. Energy audit
Develop an energy audit plan following the requirements of ASHRAE Level 2, Energy Survey and Analysis, to evaluate efficiency opportunities. [Europe ACP: EN 16247] The audit plan must include the following:
  • the audit team members and their roles and responsibilities during the audit process;
  • a description of the approach for identifying and analyzing facility improvement opportunities;
  • the process for reviewing and prioritizing identified opportunities with the owner and developing an implementation plan;
  • the format and content of the eventual deliverables from the audit process; and
  • the proposed schedule.

Performance

Apply the requirements below to all direct energy-consuming or energy-producing systems, including lighting, process loads, HVAC&R, domestic water heating, and renewable energy. Update the systems and components to be addressed as part of the existing building commissioning or energy auditing process. Provide a breakdown of estimated resource use for each of these systems.
Option 1. Existing building commissioning
Update and execute the existing building commissioning plan.
Option 2. Energy audit
Update and execute the energy audit plan following the requirements of ASHRAE Level 2, Energy Survey and Analysis. [Europe ACP: EN 16247] For each opportunity, describe the potential improvement, estimated implementation costs, and anticipated savings.

Alternative Compliance Paths (ACPs)

Europe ACP: EN 16247
Projects in Europe may use the energy audit procedure defined in EN 16247-2:2014 with a level of detail consistent with the scope of the credit. See all forum discussions about this credit »

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.

Reference Guide Correction
Description of change:
Under "Group Approach", replace the sentence "All buildings in the group may be documented as one. If so, each building in the group must use the same compliance
option to meet the credit requirements." with the following text: "Documentation may be combined provided it addresses each building individually. Each building in the group must use the same compliance option to meet the credit requirements."
