The buffering effect of heavy timber constructions on the indoor moisture dynamic

Since the renewal of the fire regulations in the 90s, an alternative to the traditional light-weight timber frame structures particularly suitable for multi-storey dwellings has recently emerged in the Scandinavian countries under the generic name of massive wood construction or heavy timber construction. This concept provides manifold architectonic possibilities for the use of wood as a building and structural material, with the particularity among others of creating large areas of wood surface being directly exposed into an indoor environment. Regarding the hygroscopic properties of wood materials, this calls upon the possibility of buffering the indoor environment in term of moisture fluctuations by making use of the structure as a passive system. This paper discusses some insights and thoughts round about the notion of moisture buffer capacity through the examination of the indoor moisture dynamic registered into four apartments during the year 2003 at the Vetenskapsstaden multi-storey dwelling located in Stockholm. Numerical results are also provided to ascertain and highlight the holistic approach lying behind this concept where the control of the indoor moisture dynamic requires taking simultaneously into consideration several aspects of the building as the ventilation strategy, the structure configuration, the building use and the outdoor climate.
