Dehumidification/cooling walls, Charleston, SC
Dehumidification/cooling walls, Charleston, SC The Lee Porter Butler hollow masonry walls with adaptive design by Ekose's associate, Robert Ader, as constructed at Nr. 1 Tranquil Drive in Charleston, as tested during June, 1983, for their power to dehumidify, appear to lower the absolute humidity level in the house when outside temperatures hit near 100/sup 0/, but then the interior of the house exceeded the upper limits of comfort, which seem to fall at 80/sup 0/ DB and 74/sup 0/ WB or a relative humidity at 80/sup 0/ of 76%. Maximum interior temperature was 82/sup 0/, perhaps dreamy by the standards of 1883, but beyond what most people have become accustomed to in 1983. It is possible that design adaptations in the building and/or defoliation on the east and west sides of the building might improve this performance - whether sufficiently enough for comfort is dubious while the lack of cost effectiveness is certain. If, as through the use of standardized masonry units, hollow masonry walls could be made both cost effective and compatible with the ever increasing earthquake zone 3 code requirements for ties, they might come close to eliminating the need for mechanical cooling and dehumidification while maintaining reasonable comfort. Certainly they would more »
