The present study intends to optimize the concept of a breast-wall panel while conciliating the architectural aspects and energy saving strategies of non residential buildings. Thus, the panel will permit besides a recovering of solar energy gains during the winter as in a classical Trombe wall (but without is thermal inertia) a reduction of solar energy inputs during summer. In order to estimate its thermal performance, a simplified model was developed predicting energy savings both in winter and in summer periods.
The carbon dioxide concentration patterns in a large, high-rise, office building in Ottawa were examined experimentally using an automated data acquisition system. Daily C02 concentration profiles throughout the building and air change rates, using SF6 as a tracer gas, were measured at minimum outdoor air supply rates during much of a heating season.
