  1. The dependence of effective thermal heat capacity of non-homogeneous materials on location and climatic parameters

    Almeida, Manuela; Garcia, Valdemar; Maldonado, Eduardo
    The effective thermal heat capacity of construction materials depends strongly on the external conditions such as solar radiation and ambient air temperatures in contact with those elements. The combination of these factors has not been correctly quantified so far. This work also describes a means for determining the thermal performance of non-homogeneous, multi-layered elements: a detailed numerical method that simulates two-dimensional heat transfer situations that occur in typical Portuguese building construction elements, such as brick walls and slabs, was developed as a tool to quantify effective thermal capacity. Correlations factors between available solar radiation, ambient air temperatures and daily heat capacity...
