Abstract
Urban heat islands (UHI) represent increase of temperature inside of cities in
regard to their rural environment. Causes of their formation are diverse and
multiple: reduced amount of vegetation and waterproofing of surfaces, changed
radiation and thermal characteristics of materials, urban geometry. Consequences
are also diverse and significant: increasing consumption of energy for cooling,
negative impact on human health, deterioration of air quality. Conventional
methods for mitigating their impact include reflective and green roofs and
introduction of green and water surfaces in cities. Different renewable energy
technologies can also have positive impact on urban heat islands, but at the same
time they contribute to greater energy independency of cities what is goal of future
urban development. Proposed and described technologies are solar cooling, groundair
heat exchanger, passive cooling, solar pond.
Keywords
