Functional relationships between emission by cars and urban pollutant concentrations: a simplified phenomenological approach
This work is aimed at providing a contribution toward the singling out of a functional relationship between the traffic flow in urban contexts and the physical dynamic of the pollutant diffusion. The values of CO concentrations in selected sites of the urban layout are obtained by utilizing as input the number of vehicles predicted by the phenomenological model here introduced. This represents a quite different approach in the simulation of the pollutant dynamics in urban contexts. One of the main features of the proposed traffic model, is the capability of realistically reproducing the characteristic of the traffic flows. The feasibility of the model to be applied in other urban situations…
Comparison of methodologies for Test Reference Year (TRY) generation for Mediterranean sites
The improvement of the energy efficiency of buildings calls for the availability of tools for evaluating and simulating the thermal behaviour of buildings. These simulation tools generally need a complete input data set and, in particular, information referring to the climatic conditions of the site where buildings are built-up. Among climatic issues, particularly important for the thermal energy balance is the solar radiation. However, this huge mass of data is not very useful in this form, so simple aggregation methods have been developed in order to run these simulation computer programs: the test reference year (TRY) is one of the most used methods. In this paper the comparison of two m…
