Report A3132.1 <br /> Page 5 <br /> Control of Interior Conditions <br /> The test but was heated in the winter and air-conditioned in the summer. The <br /> indoor temperature was initially set at 21°C. After an initial monitoring period <br /> through the first summer, this temperature was reset to 23°C, to increase the <br /> accuracy of the monitoring in the shoulder seasons. Figure 5 shows the relatively <br /> steady indoor temperature control through the monitoring period. <br /> The indoor RH was not controlled, although some summertime dehumidification <br /> probably occurred as a by-product of air-conditioning. The indoor RH profile is <br /> show in Fig 6. <br /> The drainage system featured a sump pump. The level of water in the sump <br /> was observed to be quite high (at footing level) for the first 200 days of <br /> monitoring. At day 215, the sump pump controls were reset to maintain the <br /> water level in the sump at about 300 mm below the footings. <br /> Characterization of Specimen Properties <br /> Samples and insulation products were labelled upon receipt from the manufacturers <br /> and the following properties were assessed before and after the field exposure: <br /> • density <br /> • thermal conductivity <br /> • compressive strength <br /> Average pre-exposure properties of the specimens exposed at the test but are <br /> listed in Table 1, along with other physical characteristics of the specimens. <br /> r <br />
