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. Regarding outdoor thermal comfort, possibilit...

description 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.

Aspectos como el crecimiento vertical, la presencia de vegetación y el desarrollo urbano afectan directamente varios climas, generando microclimas diferenciados en el área urbana. El objetivo de esta investigación es analizar las diferencias térmicas intraurbanas de los datos meteorológicos recopilados en estaciones meteorológicas de aficionados que pertenecen a la red Weather Underground, ubicadas en diferentes Zonas Climáticas Locales (LCZ) en Londres, Inglaterra. Se evaluó si los microclimas son lo suficientemente significativos como para definir la demanda de energía para enfriamiento / calefacción. El análisis del perfil longitudinal de las temperaturas intraurbanas indicó la generación de islas de calor, con la intensidad más alta donde el uso de la tierra y la ocupación es mayor con menos cobertura vegetal. En cuanto a la demanda de refrigeración / calefacción, las diferencias obtenidas pueden estar relacionadas con la LCZ a la que pertenece cada punto. O clima urbano é influenciado por características morfológicas e de uso e ocupação do solo. Aspectos como grau de verticalização, presença de vegetação e adensamento urbano influenciam diretamente sobre variáveis climáticas, gerando microclimas diferenciados na área urbana. Em relação ao conforto ambiental humano, a possibilidade de se prever fenômenos do clima urbano orienta decisões projetuais arquitetônicas e urbanísticas. Esta pesquisa teve por objetivo analisar diferenças térmicas intraurbanas a partir de dados meteorológicos coletados em estações amadoras participantes da rede Weather Underground, localizadas em diferentes zonas climáticas locais (Local Climate Zones - LCZs) em Londres, Inglaterra. Utilizaram-se dados meteorológicos de dez estações distribuídas nos eixos leste-oeste e norte-sul. Avaliou-se se as variações nos microclimas são significativas o bastante para suprir a demanda de energia para aquecimento e resfriamento de edificações, por meio do somatório de graus-hora de aquecimento e resfriamento para cada ponto. Pela análise do perfil longitudinal das temperaturas, a pesquisa constatou a formação de ilhas de calor nos locais com maior intensidade de uso e ocupação e menor cobrimento vegetal. Com relação à demanda por climatização artificial, notaram-se diferenças consideráveis em função da LCZ de cada ponto.
