HEALTH & WELL-BEING: ONE BREATH AT A TIME 🌬️
This session explores the critical intersection of indoor air quality, HVAC system design, and human well-being. As organizations place increasing emphasis on healthier indoor environments, understanding the science, standards, and strategies behind effective air management has never been more important. Attendees will gain practical insight into how the HVAC industry is evolving to meet today’s health, safety, and sustainability expectations.
Topics Covered
• Application of ASHRAE ETF Guidelines to Promote Healthier Buildings 🏢✨
Discover how ASHRAE Epidemic Task Force (ETF) guidance continues to influence modern building practices. We will examine recommended ventilation rates, filtration strategies, and air-cleaning technologies and discuss how these guidelines can be integrated into both new construction and retrofit projects. Attendees will leave with actionable approaches for enhancing occupant well-being and reducing airborne contaminant risks.
• Advantages and Limitations of Recommended HVAC Best Practices ⚙️✔️
Not all solutions are universally applicable. This segment breaks down the strengths and challenges associated with widely recommended HVAC best practices, including increased outdoor air, high-efficiency filtration, air distribution enhancements, and system optimization strategies. Learn where these practices excel, where they fall short, and how to evaluate the real-world trade-offs in energy, cost, and operational performance.
• Environmental Factors Influencing Infection During Cold & Flu Season – and the Myth of a Well-Mixed Environment 🦠🤧
Indoor air does not behave as uniformly as many assume. We will explore environmental drivers—such as humidity, temperature, occupant density, and air movement—that influence infection risk. This discussion also debunks the long-standing assumption of a “well-mixed environment,” illustrating how localized airflow patterns, stratification, and microzones complicate traditional HVAC modeling and pathogen control strategies.
• Innovative HVAC Design Strategies Bridging IAQ Guidelines and Decarbonization Initiatives ♻️💡
As ASHRAE advances both indoor air quality (IAQ) guidelines and aggressive decarbonization goals, design teams face the challenge of balancing health, sustainability, and energy efficiency. This portion presents forward-thinking design strategies—from demand-controlled filtration to hybrid ventilation and next-generation heat recovery—that support both goals. Discover how new technologies and system approaches can close the gap between enhanced IAQ expectations and the industry’s carbon-reduction commitments.

A JOINT ASHRAE / ASPE EVENT!!
🎉 DESIGN SPOTLIGHT: MARICOPA COUNTY TABULATION & ELECTION CENTER 🎉
Welcome to a behind-the-scenes look at one of Arizona’s most important civic hubs! The 260,000-square-foot Maricopa County Tabulation and Election Center is more than just a building—it’s a modern marvel designed to make ballot processing faster, smarter, and safer for all.
🗳️ Purpose-Driven Design:
This facility is thoughtfully crafted to streamline every step of the election process, from ballot intake to tabulation—all while ensuring the highest standards of security and integrity for the workers and the democratic process they support.
👀 Transparency Meets Protection:
Visitors are taken on a journey through the ballot lifecycle, with the building’s layout offering a guided, intuitive experience that beautifully balances openness and controlled access. It’s democracy in motion, with every step visible and protected.
🏜️ Inspired by the Desert:
Rooted in its Arizona surroundings, the design draws from the natural beauty of the desert. Think bold stone outcroppings—metaphorical anchors that ground the building both structurally and symbolically. These elements evoke stability, strength, and permanence, echoing the core values of the election process itself.
This isn’t just an election center—it’s a civic landmark, where architecture and democracy meet in the heart of Maricopa County.
