A building model was created in TRNSYS 17 to determine whether appropriate growing conditions can be maintained in a geodesic dome greenhouse in Ottawa, Canada, without the use of auxiliary power or heating. A microcontroller, the Arduino UNO, is used as the data collection device. In order to test the effects of ventilation, thermal mass, and solar panel shading on both the modelled and the measured results, combinations of these variables were used to create five operating scenarios. The model was calibrated and run under each of these scenarios, using actual 2015 weather data, and was also run for a full year using the CWEC weather data to compare the performance of each scenario for a typical weather year. The results indicate that air temperatures are expected to exceed acceptable ranges during a typical weather year, which indicates that further efforts will be required to heat and cool the Biodome.
