Analysis for improving the passive cooling of building's surroundings through the creation of green spaces in the urban built-up area

摘要

This paper focuses on the assessment of a microclimate in a city canyon in Vienna, accurately the Vienna Karlsplatz. In this canyon, there are several environments. The goal of this study was to inquire weather it makes an identifiable difference if an urban place is planted or not. This study was a comprehensive in situ investigation. The air temperature and relative humidity were tested in two places, with the first one being surrounded by greenery, and the other one by "asphalt/concrete". The thermal behavior was recorded and analyzed over various heat waves. After analyzing the complete period, two extreme heat waves of three days were singled out and analyzed in detail.
