Combating urban heat islands : assessing the potential of open-loop geothermal heat pump systems in Canada
Urban aquifers hold significant potential for sustainable space cooling solutions 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) …

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
… Many cities are suffering the 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 …

Modeling Extreme Heat Risk in Urban Areas Using Computer Vision and Data Analysis
… and environmental determinants of human 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 …

Designing With Climate: Using Parking Lots to Mitigate Urban Climate
Urban areas are known to have different climatic conditions than their rural counterparts including higher temperatures, greater wind speeds, and increased precipitation otherwise known as urban heat islands, urban wind, and urban precipitation. These phenomena are all caused by the design and form …

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 …

Spatial characteristics of the remotely-sensed surface urban heat island in Baton Rouge, LA: 1988-2003
Our understanding of urban effects on local climate remains unsatisfactory due to several difficulties: 1) the inherent complexity of the city-atmosphere system, 2) lack of a clear conceptual theoretical framework for inquiry, and 3) the high expense and enormous difficulties of acquiring a …

Impacts of Urban Areas on Vegetation Development Along Rural-Urban Gradients in the Upper Midwest: 2003-2012
… projected to increase by 2.5 billion by 2050 in urban areas alone (United Nations 2014). The rapid urbanization of our planet drives global environmental changes in hydrosystems, biodiversity, biogeochemical cycles, land use and land cover, and climate (Grimm et al. 2008). Urban areas alter local …

Process oriented infrastructure for climate-driven forest migration through cities
… a process-oriented approach to map and design urban landscapes to facilitate forest migration under climate change. The focus lies on the connectivity of urban landscapes for effective seed dispersal. Since the migration of trees is a continuing process that does not rely on their future …

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 …

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
… same time, increasing anthropogenic influence 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 …

Thermal Pollution in Urban Streams of the North Carolina Piedmont
… over the next 40 years is expected to occur in urban areas (United Nations Population Division 2012). Urban areas necessarily concentrate food, energy, and construction materials, and as a result tend to be hotter and more polluted than the surrounding landscape. All urban ecosystems are thus …
