Combating urban heat islands : assessing the potential of open-loop geothermal heat pump systems in Canada
… to help address the growing issue of urban heat islands, yet their suitability has remained underexplored. This study presents an assessment of urban aquifer suitability for cooling with groundwater heat pump (GWHP) systems in 10 Canadian cities. A numerical model was then developed for a …

Reimagining Urban Leftover Spaces Under Overpasses: Mitigating Urban Heat Islands and Heatwaves Through Green Space Transformation
The urban thermal environment is deteriorating due to the constructed urban space and climate change, which negatively impacts public health, especially in the Urban Canopy Layer (UCL). Recent research has investigated the contribution of microclimate parametric in specific urban typologies such as …

Mitigating urban heat island effects : An analysis of precinct ventilation performance and its impact on urban heat islands and outdoor thermal comfort
… severe impacts of urban climate change via urban heat islands (UHI) effects. Wind is a critical factor for urban temperature regulation. However, the potential of utilising natural wind for UHI mitigation is significantly constrained by the limited knowledge on urban ventilation at the precinct …

Modeling Extreme Heat Risk in Urban Areas Using Computer Vision and Data Analysis
… health. Urban areas suffer the effects of urban heat islands, which exacerbate the temperature rise from extreme heat events because they have more paved surfaces, less vegetation, and more heat created from human activities. As a result, heat risk modeling aims to reduce heat risk for vulnerable …

Designing With Climate: Using Parking Lots to Mitigate Urban Climate
… increased precipitation otherwise known as urban heat islands, urban wind, and urban precipitation. These phenomena are all caused by the design and form of the city. Large amounts of impervious surface area, obtrusive buildings, and a lack of vegetation in the urban landscape all contribute to …

Spatial characteristics of the remotely-sensed surface urban heat island in Baton Rouge, LA: 1988-2003
… remotely-sensed data, this study analyzes urban heat islands (UHI) that are manifested through an elevation in the surface thermal emissions within urban regions known as surface heat islands (SHI). The study area for this research endeavor is Baton Rouge, Louisiana. Whereas the surface air …

Public perception and response to extreme heat events
In the United States extreme heat events have grown in size and stature over the past 20 years. Urban Heat Islands exacerbate these extreme heat events leaving a sizable portion of people at risk for heat related fatalities. The evidence of this is seen in the Chicago heat wave of 1995 which killed …

Smart coatings for energy saving buildings
… local outdoor microclimate, mitigating urban heat islands effect (UHIE). The primary purpose is to produce pigments according to an environmentally friendly route, using non-toxic raw materials, as well as short times and low temperatures for synthesis, and without residual waste. The …

Internet of Things (IoT) application for hydrological measurements: measuring the Urban Heat Island effect
… data collection method for studying the Urban Heat Island Effect (UHIE). Urban Heat Islands (UHIs) are localised and typically built-up areas, that experience significantly higher temperatures than the surrounding undeveloped areas. This temperature difference is primarily due to increased heat …

A multi-city analysis of the natural and human drivers of the urban heat island
… to the surrounding rural areas, called the urban heat island, which can have negative impacts on the health and wellbeing of urban dwellers. This study uses a novel approach of analyzing a large number of cities from around the world to investigate the similarities and differences in urban …

Impacts of Urban Areas on Vegetation Development Along Rural-Urban Gradients in the Upper Midwest: 2003-2012
… releasing energy through anthropogenic heat sources, and increasing atmospheric aerosols, leading to increased temperatures in cities compared with surrounding rural areas, known as the “urban heat island” effect (Arnfield 2003). Recent urbanization of our planet has generated calls for …

Process oriented infrastructure for climate-driven forest migration through cities
… cities could provide suitable climatic (urban heat islands) and environmental conditions for the persistence of outlier populations at higher latitudes than their native ranges, thereby shortening or even eliminating migration lags in tree species. The proposed process-oriented approach maps …

The effectiveness of Urban Green Infrastructure for urban heat regulation.
Excess urban heat is one of the significant challenges for cities, which combinedly occurs and exacerbates with urban heat islands, heatwaves and climate change impacts. It diminishes the quality of urban life and makes cities intrinsically more vulnerable than rural areas. Extreme heat has claimed …

Φαινόμενα θερμικής νησίδας συνδεδεμένα με πολεοδολικές και κλιματικές παραμέτρους
Η εργασία αυτή στηρίζεται σε δύο πειράματα. Στο πρώτο πείραμα μελετήθηκε για καλοκαιρινούς και φθινοπωρινούς μήνες το φαινόμενο της αστικής θερμικής νησίδας σε συνδυασμό με την γεωμετρία της πόλης. Πρόκειται για ένα πείραμα που έγινε σε τρεις παράλληλες αστικές χαράδρες με διαφορετική γεωμετρία και …

Evaluation of the effect of urbanization on urban thermal behaviour using urban heat island indicators: the case of the CBD of Accra.
Various studies have shown that urban heat island (UHI) can significantly affect the local climate of the built environment. Extreme air temperatures and heat waves adversely affect people's health, their overall well-being and productivity. Tropical urban sites are constantly under the threats of …

Driving forces and barriers for adaption strategies against the urban heat stress hazard in Berlin, Germany
… on urban climates is leading to worsening urban heat stress. Increased amounts of impervious area, dark surfaces, and the barrier effect of large buildings reduce the ability of especially dense, inner-city areas to cool themselves. The effects of climate change inside the city can vary greatly …
