Data were collected at the RPI Visitor Center using an Aeolian Kinetics PDL-24 data acquisition system. Instantaneous data readings were recorded each 15 seconds by the microprocessor. These cannel readings were then averaged to produce hourly values which were then stored on an audio cassette. These hourly data were then transcribed to the AIAF archive. Energy conservation measures consist of R-20 to R-27 walls and R-27 to R-38 roofs. All windows are double glazed and all entrances have air locks. The concrete block northern walls are earth bermed and insulated with 3-inch urethane foam. Walls and floors in the attached sunspace provide thermal mass that collect and redistribute heat to the parent space during the heating season. This is accomplished with thermostatically controlled fans that draw heat from the sunspace. If the space thermostat is still not satisfied, the duct heaters are activated. If temperatures are still too low for comfort, individual time-controlled radiant ceiling heating panels can be activated by the occupants. During the cooling season natural ventilation is provided by convective air flow through the sunspace and out the ventilation/light tower. Although there are only 600 cooling degree days a year the area's high relative humidity increases cooling needs. When cooling is necessary the system first uses outside air. When enthalpy of outside air is greater than the set point, cooling is provided by a direct expansion coil.
