Calculated Conditioning: The IAQ Of UFAD

UFAD and displacement ventilation systems require accurate estimates to meet relative humidity requirements and ensure efficient operations. Take a look at a few design options, and contemplate the reader challenge at the end.
April 26, 2013
Since their introduction in Europe in the 1950s, and their domestic rise in specification during the 1990s, UFAD and displacement ventilation systems promise significant energy savings as a direct result of a higher supply air temperature that yields an increase in the use of economizer or free cooling hours.

Energy-Efficient Dehumidification In Health Care Facilities

October 31, 2012
With a wide spectrum of specialized spaces and particular outside air requirements, a hospital’s en-ergy-efficiency efforts start when arranging which areas go where. From there, the author leaves no technology unturned — chilled beams, geothermal, DOAS, VRF, etc. — in evaluating which ap-proaches might best contribute proper ventilation and humidity in which environments, with an eye on minimizing facility energy consumption.
