Intent

To promote resilience and reduce the environmental and economic harms of excessive energy use and greenhouse gas emissions by achieving a minimum level of energy efficiency.

Requirements

Projects registering before January 1, 2028, may comply with either Option 1 or Option 2.
Projects registering on or after January 1, 2028, must comply with Option 2.

Option 1. ASHRAE 90.1-2019
Comply with ANSI/ASHRAE/IES Standard 90.1-2019 with addendum cr. Use any applicable compliance path in ASHRAE 90.1, Section 4.2.

For projects applying the Normative Appendix G, Performance Rating Method compliance path, the future source energy metric may be used in place of cost:

Replace all references to cost with future source energy. Use an electric site-to-source energy conversion factor of 2.0 based on future projections for the U.S. A lower national average value may be used as applicable for projects outside of the U.S.
Replace ASHRAE 90.1-2019, Table 4.2.1.1, Building Performance Factors (BPFs), with the BPFs derived for the future source energy metric in Table 1.

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.
