Abstract

In order to evaluate green shade effects of pergola for thermal environment of car parks quantitatively, temperatures of air and ground surface, in and out side of car bodies, as well as direct insolation, and wind velocity were measured both in sunny and shaded sides. Dashboard's temperature reached over 70 °C in sunny side, when it remained over 10 °C of air temperatures in shaded side. Differences between ground surface temperature of sunny and shaded side were strongly affected by ratio of pergolas'roof cover ratio. Green shade effects of pergola considered enough for improving thermal environment of car parks. Also, idling stop to control carbon dioxide emission were expected by setting pergola above car parks.
