Urban Ventilation - A New Concept and Lumped Model

With the rapid development of urbanization, the economy and number of vehicles, the urban climate has worsened in recent years, causing serious urban problems including urban heat islands, air pollution and infectious disease transmission. Ventilation is indicated as one of the most effective approaches to solve these problems.

Determination of places in the great Athens area where the heat island effect is observed

The main purpose of the present study is to define places in the major Athens area where the heat island effect occurs. Several important climatic parameters are examined in combination with the application of various statistical tests. From this research it is mainly observed that the central and the west industrialized parts of the city of Athens develop intensely the urban heat island effect.
