Correlations between dynamic thermal properties, energy consumption, and comfort in wood, concrete, and lightweight buildings

Résumé: An office building located in Québec City (QC, Canada) with different envelope assemblies has been simulated to determine the energy consumption and thermal comfort that they provide. The resistance, thermal mass, and materials (concrete, cross-laminated timbers (CLT), and light-frame) were varied in a series of 164 different scenarios, and the energy intensities for heating and cooling were determined in each case, along with the discomfort index. Results show that the materiel used to provide thermal mass has a larger impact on comfort and energy consumption than the value of the thermal mass thickness itself. It was also attempted to correlate the performance of the envelope assessed through energy simulations with four dynamic thermal properties (i.e., dynamic transmittance, areal heat capacity, decrement factor, and time lag). The internal areal heat capacity appeared to be the most important variable to explain variations of performance of the envelope.
