    Monthly Chapter Meeting

    Are Green Buildings Good for Us?

    Dr. Patrick Phelan
    Assistant Dean of Graduate Programs and Professor
    School for the Engineering of Matter, Transport and Energy
    Arizona State University


    The push to make buildings “green” continues, especially with California law mandating that new residential buildings be net zero energy in 2020, followed by new commercial buildings in 2025.  Yet, are such energy-efficient buildings good for the health and productivity of their occupants?  How does air conditioning, which is essential in Arizona and increasingly important in other parts of the world, impact our health?  This presentation reviews the available literature to begin addressing these questions.
