Per EPACT 05, Section 109, Federal Building Performance Standards, if life-cycle cost-effective for new Federal buildings, the buildings are to be designed to achieve energy consumption levels that are at least 30 percent below the levels established in the effective version of the ASHRAE Standard. Sustainable design principles are to be applied to the siting, design, and construction of all new and replacement buildings. If water is used to achieve energy efficiency, water conservation technologies shall be applied to the extent that the technologies are life-cycle cost-effective.
Per the National Defense Authorization act 2022, DOD is to: “incorporate the latest consensus-based codes and standards for energy efficiency and conservation, including the 2021 International Energy Conservation Code and the ASHRAE Standard 90.1-2019.” UFC 1-200-02 states, “For commercial and multi-family high-rise buildings with design starts on or after 7 April 2023, meet the requirements of ASHRAE 90.1-2019.” ASHRAE 90.1 2019 increases difficulty of meeting energy reduction goals in a Life Cycle Cost Effective manner for the Army.
Per 10 CFR 433 and UFC 1-200-02 High Performance and Sustainable Building Requirements, DoD projects must meet the requirements of ASHRAE 90.1 Energy Standard and achieve at least 30% energy consumption reduction from the ASHRAE 90.1 baseline. Per 10 FR Part 433, ASHRAE 90.1-2019 will replace 90.1-2013 as the current design standard starting April 2023.
