摘      要：Two attics were constructed as part of a building renovation project at the University of West *** first attic is described as a traditional ventilated attic,with open-ings in the soffits and a small dormer vent on the *** second attic is described as a sealed attic(with no ventilation),and open-cell spray foam insulation installed on the underside of the roof *** study was undertaken to demonstrate hypoth-esized performance differences between attic *** and relative humidity sensors were installed to measure the condition of the air in the two attics spaces,and measurements were taken at 15 minute *** of relative humidity were later calculated as dew point and specific *** studies are often conducted by comparison of attics in separate buildings under different use *** project offers a unique opportunity to explore data collected from a single structure,and provides support for existing research on attic design in southern *** resultant data show significant differences in attic temperatures,with the sealed attic exhibiting a much more thermally stable *** were also significant differences in attic dew points and specific humidity,although these dif-ferences appear to be much less *** were analyzed using independent t-tests to establish significant differences between ***,the sealed attic performed better than the ventilated attic,although dew point and specific humidity remain concerns.
