AIA Dayton and ASHRAE Joint Meeting
As we move increasingly toward market viable net-zero buildings with initiatives like ASHRAE Vision 2020 and AIA 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.
8:15 AM Breakfast
8:30 AM - 9:30 AM
Topic: Air Movement for Energy-Efficient Comfort in Conditioned Spaces
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.
9:30 AM - 10:00 AM Tour of Aileron for those interested
