Evaluation of microclimatic effects of local climate zones in a city with temperate climate

Urban climate is influenced by morphological features and land use and occupation. Aspects such as vertical growth, presence of vegetation, and urban development directly affect various climates, generating differentiated microclimates in the urban area.

Description
Summary:Urban climate is influenced by morphological features and land use and occupation. Aspects such as vertical growth, presence of vegetation, and urban development directly affect various climates, generating differentiated microclimates in the urban area. Regarding outdoor thermal comfort, possibility to predict phenomena related to urban climate may guide design decisions in architecture and urban planning. This research aims to analyze intra-urban thermal differences from meteorological data collected from amateur weather stations belonging to the Weather Underground network, located in different Local Climate Zones (LCZs) in London, England. Meteorological data from ten amateur weather stations were used, which are distributed in east-west and north-south axes. The study evaluated if variations in microclimate are significant enough to define energy demand for cooling/heating using the sum of degree-hours for heating/cooling. The analysis of the longitudinal profile of intra-urban temperatures indicated that the generation of heat islands, with the highest intensity where land use and occupation are higher and with less vegetation cover. As for cooling/heating demand, obtained differences can be related to the LCZ each point belongs to.
