Using Computer Simulations for Assessing Microclimatic Impacts of Urban Interventions
نویسندگان
چکیده
The purpose of the present paper to estimate the impact of alterations in urban design on local microclimate in three different locations: a densified area of São Paulo, Brazil, a district in Paris, France and an industrial area in Geneva, Switzerland, which is undergoing urban redevelopment. Computer simulations were run with the program ENVI-met in all cases, including a calibration procedure from in situ measurements. The effects of the introduction of urban parks and greenery are assessed in terms of local temperature reductions, under summer conditions. It was found that by introducing vegetation in the urban environment, temperature reductions can range in those cities between 0.6 and 2.2°C and in some cases the effect is highly localized, pointing to the importance of better greenery distribution in cities rather than concentrated urban parks.

This paper investigates urban bioclimatic interventions in the central area of a coastal medium-sized city in Greece. Two urban blocks typical of the urban fabric of the city center and a neighborhood of 38 urban blocks were selected. Different proposed Bioclimatic Renewal Scenarios were investigated through microclimatic simulations using the micro-scale numerical model, ENVI-met. The simulati...

متن کاملThe Extent and Implications of the Microclimatic Conditions in the Urban Environment: A Vienna Case Study
Recent challenges in the realm of urban studies concern better understanding of microclimatic conditions. Changes in urban climate affect cities at local and global scales, with consequences for human health, thermal comfort, building energy use, and anthropogenic emissions. The extent of these impacts may vary due to different morphologies and materials of the built environment. The present co...

The Urban Heat Island (UHI) effect is a welldocumented phenomenon, in which the airtemperature in an urban area is elevated relative to the regional air-temperature. This paper evaluates two recently developed methods for generating urban weather files from a rural station that account for microclimatic impacts on dry-bulb temperature and relative humidity. The two methods examined are computat...
