Why air movement matters to a facility's energy efficiency
It's important to reevaluate how traditional building components can influence a facility's energy efficiency, especially as the market moves toward more net-zero buildings with initiatives, such as the ASHRAE Vision 2020 and the 2030 Challenge.
Elevated air speed has a significant impact on thermal comfort, according to ASHRAE 55. 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 us to include 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.
- Identify the primary factors affecting human thermal comfort and the basics of ASHRAE Standard 55-2013, as well as the ASHRAE Thermal Comfort Tool.
- Understand how to incorporate elevated air speed to increase air distribution efficiency and maximize energy savings within air conditioned spaces.
- Learn additional design benefits of minimizing ductwork, lowering HVAC first costs, improving ventilation rates and mitigating condensation.
- Understand stratification and the significant energy saving potential from destratifying a large open space.
