| Abstract | In basement wall systems, airspaces can contribute in obtaining a higher thermal resistance, if a reflectivematerial such as reflective foil is installed on one side or the other of a furred-airspace. In this paper, thehygIRC-C model was used to investigate the steady-state and transient thermal performance of abasement wall system that incorporate foil bonded to expanded polystyrene (EPS) foam in a furred assembly having airspace next to the foil. The furring was installed horizontally. The external layer ofthis wall is a poured-in-place concrete. Walls with and without Furred-Airspace Assembly (FAA) wereconsidered in this study. Also, consideration was given to investigate the effect the above- and below grade portions of the wall on the thermal performance when these walls were subjected to a Canadianclimate. Results showed that the effective thermal resistance of a wall with FAA at steady-state conditiondepends on the soil, outdoor and indoor temperatures. Additionally, a wall with FAA and low foilemissivity (0.04) bonded to EPS foam resulted in an energy saving of 17.7% compared to a wall withoutFAA when these walls are subjected to the same climate condition. |
