Attachment 2 - 2024 HVAC Chiller JA - AQ Signed 10 Sep 24.pdf

This is a Justification & Approval (J&A) document for Other Than Full and Open Competition for HVAC chiller standardization across Department of Air Force (DAF) installations, with an estimated contract cost of $437.5M. The J&A covers DAF HVAC chiller purchases from October 2024 through September 2029, expecting to replace 1,654 units that are at least 17 years old by 2029.

The document justifies standardizing HVAC chiller manufacturers at each DAF installation to reduce total cost of ownership through improved training efficiency, cybersecurity, and maintenance. The strategy allows each installation to select from approved manufacturers, with 92% of purchases going to small businesses through authorized distributors. Key results show standardization has reduced manufacturers from 142 in 2018 to 127 in 2024, with twelve bases achieving 80% standardization. The primary manufacturers are Trane (57.5%), Carrier (28.7%), with others including Daikin, York, LG, Mitsubishi, Dunham-Bush, Exhausto, Blue Box, Uniflair, and United Technology representing smaller percentages. The program has already achieved $50M in training cost avoidance and improved cybersecurity, resilience, and mission effectiveness through standardization.
