Browning Day Mullins Dierdorf Architect Receives WELL AP Credential

Browning Day Mullins Dierdorf Director of Sustainability Daniel Overbey, AIA, LEED AP (BD+C, ID+C, O+M), has recently earned the WELL Accredited Professional (AP) credential, making him among the first in Indiana.

The WELL AP credential signifies knowledge in human health and wellness in the built environment, and specialization in the WELL Building Standard, which focuses on seven categories of building performance: air, water, nourishment, light, fitness, comfort and mind.

“Human health is an emerging priority, and much like the world we live in, architectural design is undergoing a unique period of rapid change,” Overbey said. “I believe truly valuable design can only be achieved by tracking and utilizing the innovations in technology, practices, and materials that are moving the profession toward a more intelligent and positively effective future.”

Overbey is recognized for his work in the area of environmental design and building systems analysis. He brings a unique evidence-based design approach to his project teams at Browning Day Mullins Dierdorf Architects. His work includes the Simon Skjodt International Orangutan Center at the Indianapolis Zoo, the LEED Gold certified Global and International Studies Building at Indiana University, and the Chrisney Branch of the Lincoln Heritage Public Library – the first Net Zero Energy Building (NZEB) to be certified in Indiana.

“Dan is a leader in this industry and is on the cutting edge of sustainable design,” said Tim Wise, vice president and associate principal at Browning Day. “We are fortunate to be able to weave Dan’s unique skills into our team’s leadership and design, and his recent certification will add another highlight to what we do.”

Prior to joining the firm in 2008, Overbey worked for a non-profit education, demonstration, and research organization in Austin, Texas as well as an architectural research lab in Las Vegas, Nevada. Currently, Overbey provides research, design, and building systems analysis services to various projects. Before earning a Master of Architecture degree from the University of Nevada, Las Vegas in 2007, he earned a Bachelor of Architecture and Environmental Design degree from the Ball State University College of Architecture and Planning in 2005.

Overbey is actively engaged in research, practice, academia, and service. His research-based background in building science and environmental systems has enabled him to be an effective design leader, educator, and policy shaper. Overbey is a regularly published author and speaker on sustainable design practices and is a past chair of the U.S. Green Building Council Indiana Chapter.
