On the analysis of cool roofs for cooling system efficiency

Cool roof is a well-documented passive cooling strategy for buildings in several climate conditions. The mechanism consists of the reduction of the heat load entering the roof, which is characterized by high solar reflectance and high thermal emittance. The purpose of this paper is to study the coupled effect produced by such a technology. First, the passive cooling contribution is quantified, then, the “active” contribution is investigated.

e-EPBD: A distance training tool for the energy performance buildings directive

The scope of the present paper is the presentation of a dynamic and interactive vocational training tool for the implementation of the Directive 2002/91/EC.Certain features of the tool that depend on the existing legislation and restrictions in each country and certain characteristics of the trainees (e.g. profession, scientific background) that influence in a great or in a small extent the training procedure in each case are analyzed.
