“Air Movement for Energy Efficient Comfort in Conditioned Spaces”

BIO

Parker Abdo grew up in Southern California, but Orange County couldn't contain him past high school. A small school in Boston, named Wentworth Institute of Technology, came calling and lured the sun loving California native to the harsh New England climate. While at Wentworth, Parker gained invaluable experience in the engineering workplace while interning at Wyman-Gordon (North Grafton, MA) and Lytron, Inc. (Woburn, MA). He also had a yearlong internship working for the Providence Bruins, AHL team of the Boston Bruins, and played rugby on the school's club team. In August of 2015, Parker graduated with a degree in Mechanical Engineering and a minor in Entrepreneurship. Soon after, Parker was hired by Big Ass Solutions to be their Western US Architect/Engineer Specialist based out of Los Angeles and has become a wonderful asset since being sent to his territory.

 TOPIC

As we move increasingly towards market viable net-zero buildings with initiatives like ASHRAE Vision 2020 and the 2030 Challenge, we must reevaluate the role that typical building components play in a facility’s energy efficiency. ASHRAE 55 has highlighted the impact of elevated air speed on thermal comfort, and in recent years innovative designs have reestablished air movement as an integral part of occupant comfort and energy conservation. Furthermore, recent changes to Appendix G of ASHRAE 90.1 allow the inclusion of energy savings from using elevated air speed in energy simulations. When integrated into new building designs, air movement allows a reduction of air conditioning capacity and ductwork. In the winter, low speed air circulation redirects heated air trapped at the ceiling, resulting in significant energy savings. Project teams working on net-zero buildings have proven the effectiveness of incorporating air movement in building plans as part of an integrated design strategy.

Learning Objectives:

1. Identify the primary factors affecting human thermal comfort and the basics of ASHRAE Standard 55-2013, as well as the ASHRAE Thermal Comfort Tool.

2. Understand how to incorporate elevated air speed to increase air distribution efficiency and maximize energy savings within air conditioned spaces.

3. Learn additional design benefits of minimizing ductwork, lowering HVAC first costs, improving ventilation rates and mitigating condensation.

4. Understand stratification and the significant energy saving potential from destratifying a large open space.
