In this EnergyPlus demo, we show how something as basic as minimum airflow during heating can be misrepresented in simulations—and how common this is with VAV systems which may be using Guideline 36 controls.

This presentation was delivered on October 7th as part of the I-REN virtual Fall 2025 C&S Forum: Resiliency in a Changing Energy Landscape. It explores key strategies for designing buildings that remain safe and habitable during extreme heat events and utility outages. Focusing on passive survivability and resilience in mild and hot climates, it outlines how thoughtful design can prevent overheating and maintain critical life-support conditions when mechanical systems fail.

This presentation was given at the 2025 Net Zero Conference on October 1st in Los Angeles. It investigates the growing overlap between high-demand data center development and mixed-use residential zoning. It examines how shared infrastructure and land-use strategies might enable data centers and housing to co-exist, leveraging collaboration between energy, heat-reuse and urban planning.

A2 Efficiency shared insights on balancing compliance, precision, and real-world building performance to advance net-zero goals during the CalBEM Spring Working Group cross-pollination meeting.

A2 Efficiency led a workshop during the Getting to Zero Forum exploring strategies for integrating data centers and central campus HVAC systems into sustainable, efficient mixed-use projects.
