Setting up a database of indoor climate measurements in recently built Belgian dwellings

One of the major sources of problems in dwellings -if not the main source- is moisture, especially due to surface and interstitial condensation on walls and roofs. For this reason, it seems important to evaluate the current standardisation and reference documents dealing with moisture and eventually to develop new assessment methods. This is the goal of the Belgian project "Moisture problems in roofs", carried out by BBRI, KUL, RUG and W&K. The first step is to collect a large number of indoor climate measurements in recently built dwellings built. A monitoring program is currently carried out. Temperatures and relative humidity levels are measured every 10 minutes in 5 rooms (as well as outside) of 41 dwellings, during several months. CO2 is monitored in 3 dwellings, in the same rooms and at the same frequency. Pressure differences across the roof are measured in 1 dwelling, at a frequency of 1 measurement every minute. All these collected data are gathered in a database that is presented in this paper. It is intended to make this database available to the scientific community.
