RENEWABLE ENERGY SOURCES AND OTHER ENERGY TECHNOLOGIES AS A MEASURE FOR MITIGATING THE IMPACT OF URBAN HEAT ISLANDS

Sa？etak 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
