A single family home of the direct gain type was instrumented and monitored in the National Solar Data Network (NSDN). The building is a single level 125 sq. M (1360 square foot) structure fitted with two types of double glazing in both sun wall and clerestory configurations. Collected solar energy is stored in an insulated floor slab, and insulated and earth beamed concrete end walls. Two F-chart/SLR models were developed based on site information and measured performance. One model (Typical Design) used similar input data as would have been available to solar designers in the region, the measured BLC and thermostat set points similar to those observed during monitoring. The second model (Adjusted) was adjusted to account for the continuous very low set point temperature selected during the unoccupied period and used measured loads and weather input data. These model results were compared to measured data during both occupied and unoccupied periods. The F-chart/SLR run results showed that indoor temperature setpoint, loads and weather data adjustments were required to make the model results approach the measured results from the period prior to occupation. Following occupation the data from both the measurements and the ''design'' model run indicated good agreement.
