Temperature and relative humidity measurements and data analysis of five crawl spaces

Abstract

This paper presents the results of one year long temperature and relative humidity measurements from five cold crawl spaces. The results are presented using a set of indicator values which have been selected to be simple to use and descriptive. Compared to outdoor air conditions, periods of colder temperature and higher moisture content occurred in all the measured crawl spaces. However, not all structures behaved similarly, which can be seen from the indicator values. Based on the analysis the largest differences occurred in the temperature conditions and in the number of condensation risk hours.
