Apart from the most common 1H and 16O we have the sister isotopes: deuterium D and 18O in water. Isotope fractionation (the change in its concentration) occurs in any thermodynamic reaction. The isotopic composition serves as a distinct mark for each

The purpose of this article is to analyze the effects of thermal mass on heating and cooling energy in Nordic climate and for modern, well-insulated Nordic buildings. The effect of thermal mass is analyzed by calculations made by seven researchers an

PurposeWater damage is a severe problem in modern construction, causing economic loss and health implications. The patented Air Gap Method, which is a slight modification of the common infill wall construction, provides means to build houses in a mor

In an office building equipped with a thermally activated building component system (TABS) detailed in situ measurements have been performed. The measurements presented in this paper have been concentrated on the concrete core conditioning (CCC) syst

RC-networks for the description of heat transfer in thermally activated building constructions have been developed. Both a simplified star-network as well as a triangular network has been used. While the star-network is less complex than the triangul

Thermal bridges play a relatively large role in heat loss with increasing thermal insulation level of building envelope. In this paper, multi-dimensional dynamic models are set up to predict the thermal performances of thermal bridges using a frequen

Cooling with free convection cooling baffles has attracted increasing interest in Sweden in recent years. Risk of surface condensation is a practical restriction. Consequently, it is required that the inlet water temperature of a cooling baffle must
