Requirements
Project teams may meet the requirements of ISO 50002:2014 Energy audits – Requirements with guidance for use as an alternative to the ASHRAE Procedures for Commercial Building Energy Audits.
EAp1 Energy Efficiency Best Management Practices – Planning, Documentation and Opportunity Assessment (Prerequisite)
Perform an energy audit that includes the level of detail specified by an ISO 50002 Type 1 audit. This procedure meets the requirements of an ASHRAE Level I walk-through assessment by providing a high-level overview and preliminary assessment of energy saving opportunities, typically with low-cost and short payback.
EAc2.1 Existing Building Commissioning – Investigation and Analysis Option 2 (2 points)
Perform an energy audit that includes the level of detail specified by an ISO 50002 Type 2 audit. This provides an additional level of detail beyond a Type 1 audit, typically to identify medium-cost improvements and opportunities for further investigation in a Type 3 audit.

Credit Specific
Project teams pursuing ISO 50002 should upload a final energy audit report that follows the contents set in Chapter 3, “Principles” and Chapter 4, “Performing an energy audit” to ensure that documentation is compliant with the scope of this prerequisite and credit. In particular, the following elements must be included: For Type 2 energy audits:- Estimate savings from utility rate change
- Compare EUI to EUIs of similar sites
- Summarize utility data
- Estimate savings if EUI were to meet target
- Estimate savings from utility rate change
- Compare EUI to EUIs of similar sites
- Summarize utility data
- Estimate savings if EUI were to meet target
- Estimate low-cost/no-cost savings
- Calculate detailed end-use breakdown
- Estimate capital project costs and savings
- Complete building description and equipment inventory
- Document general description of considered measures
- Recommend measurement and verification (M&V) method
- Perform financial analysis of recommended EEMs
Additional Guidance
Like the ASHRAE Procedures for Commercial Building Energy Audits, ISO 50002 specifies three levels of energy audit according to the level of detail involved. These three levels are defined in Annex A, "Guidance on the use of this international standard" and "Table A.1 – Indicative details of energy audit types". Project teams pursuing a Type 2 audit may wish to perform both the Type 1 and Type audits together. Note that ISO 50002 Type 2 is not as specific as ASHRAE Level II in certain cases. It is the responsibility of the energy auditor to set a level of detail that is consistent with the scope of the credit and ASHRAE Level II. For instance, project teams must include certain verification plans for LEED documentation that are not typically furnished as part of an ISO 50002 Type 2 audit. The use of EN 16247 or ISO 50002 may be particularly helpful for project teams in Europe who have or will conduct energy audits for regulatory compliance pursuant to Article 8 of the Energy Efficiency Directive (2012/27/EU).Table 1.

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.
