ASHRAE’s flagship conference, with deep technical sessions on building systems, HVAC engineering, and energy efficiency. The TC 9.9 committee — which sets the thermal guidelines every data center operates within — regularly presents updated recommendations here.

If you design or manage cooling systems, this is where the standards that define your operating envelope get debated and revised. Also strong on energy modeling, psychrometrics, and commissioning.

Produced by: ASHRAE
Focus: HVAC systems, thermal management standards, TC 9.9 data center guidelines, energy efficiency, refrigerant transitions
Relevance to DC: ASHRAE sets the thermal envelope guidelines (A1-A4 classes) that every data center cooling system is designed to meet
