Estimation of relative humidity for thermal comfort assessment

.In this paper, relative
humidity estimates were compared with measured
relative humidity values in four different low-cost
houses in Curitiba-Brazil (latitude = 25o
, altitude = 914m). This comparison comprises: a) a
statistical analysis and b) the evaluation of
comfort levels on the Building Bioclimatic Chart.
In the statistical analysis, correlation coefficients
were analyzed and in the evaluation of comfort,
measured and estimated values were plotted in the
chart and the percentage of hours within each
zone was compared. The four different
construction systems were: a wood board house,
plastered on both sides; a reinforced concretepanel
house; a reinforced polystyrene plastered
board houses; and, a house made of pre-molded
pillars spaced with concrete prefabricated plates.
These four houses were occupied during the
monitoring period. Measurements (with HOBO data-loggers)
were carried out in 15 days with a
sampling time of 15 minutes.
