Theme C: Education and Market Transformationiii) Basecase:For the purpose of comparison, a third base case model is also structuredconsisting of no GCHS.3.3 Simulation Results1) Air Temperature inside the systemsTemperature change inside the GCHS systems is simulated to test their potential ofheating and cooling the room air. As a result, GCHS Model I achieved an extremetemperature drop of 5.1°C on the hottest hour of a year and an extreme temperaturerise of 6.0°C on the coldest hour of a year; GCHS Model II achieved an extremetemperature drop of 6.6°C on the hottest hour of a year and an extreme temperaturerise of 7.9°C on the coldest hour of a year (Charts 03 to 06).Temperature Drop in Pipes in the Hottest Hour -GCHS Model ITemperature Rise in Pipes in the Coldest Hour -GCHS Model I°C383736353433323130292836.835.332.831.7Ext.
