| Résumé | The study of building materials durability and aging are essential to characterize new products, optimize the performance of buildings and adjust the building code for the climate found in Canada. To understand how the properties of a material change over the span of its service life, accelerated aging is often performed. The prerequisite to effective accelerated aging of building materials used in the building envelope is to have a thorough understanding of the aging conditions in the building envelope. To this effect, temperature and relative humidity data within the envelope of the Canadian Centre for Housing Technology (CCHT) at the National Research Council of Canada was examined. This is an instrumented house with brick cladding for which data was recorded on an hourly basis from 2004 to 2009. The data reported is for a south-facing and east-facing walls, and a south facing roof. The temperature data for the south facing wall was used to determine fluctuations in the high-ends of the average monthly temperatures. The monthly temperatures varied from ‒25 °C to +45°C for the years 2004-2009, from which the normalized average temperature distribution was calculated. The results showed two distinct peaks one at about 0˚C and the other one at 20˚C (Figure 1). These two peaks suggest the bimodal distribution of data for the “hot” months (April to September) and “cold” months (October to March). |
