ABSTRACT
The reduction of energy consumption for cooling should be addressed on a city level since the urban environment where the building operates increases its cooling needs and deteriorates the heat pumps operation. In the present work, a Computational Fluid Dynamics (CFD) model is used to study the improvement of microclimate conditions in an urban agglomeration of the city of Volos, through bioclimatic interventions. The Boussinesq approximation is used in order to take into account the thermal buoyancy while the Discrete Ordinate (DO) model is used for the radiation transport. The ground temperature is calculated by solving an energy balance model while the ground is also considered an infrared diffusive radiation emitter. The planted surfaces are considered finite thickness heat sinks and the roofs and building walls are also took as finite thickness isothermal walls and heat sources (the heat pumps and electrical device operation, lighting and, residences presence). Trees are regarded as porous volumes. The surfaces of water elements are considered isothermal heat sink walls. The local microclimate before and after the bioclimatic interventions is presented by comparing the temperature and wind speed distributions as well as the thermal comfort indices for a typical summer day.
