Product Description

From schools to shopping malls, we’ve become accustomed to over air-conditioned spaces – a design habit that is wasteful from both a business and an environmental perspective. The innovative HVAC design strategy that pairs traditional air conditioning with energy-efficient air movement permits a substantial offset of necessary HVAC capacity and likewise improves air quality by ensuring fresh air reaches the occupant breathing zone. After construction is complete, the incorporation of air movement allows a reduction in energy consumption, as end-users can raise the thermostat setpoint without sacrificing comfort. This presentation will review recent changes to ASHRAE Standards 55 and 90.1 which substantiate the impact of elevated air speed, and will explore benefits of this innovative HVAC design strategy.
