Various studies have shown that ductwork leakage has a major impact on energy use (i.e. increased fan energy use, heating & cooling losses etc.). However, in most European countries, it is not common to perform ductwork airtightness tests, which is probably due to the lack of awareness on the consequences of ductwork leakage. As follows, ductwork airtightness is not properly taken into account in most Energy Performance Regulations and Calculations.

This guide, released by the Building Services Research and Information Association (BSRIA), describes the conditional and unconditional methods of airflow measurement as well as the minimum benchmark method. The document responds to a requirement in the England and Wales Building Regulations for mechanical ventilation air flow testing, by making sure that the methods used for measuring airflow rates are fit for purpose. The aim of this guide is to help improve the standard of domestic ventilation installations.

As an introduction to this special issue on urban heat islands and cool communities, this paper reviews some of the characteristics of urban climates and the causes and effects of urban heat islands. In particular, the impacts of surface albedo, evapotranspiration, and anthropogenic heating on the near-surface climate are discussed. Numerical simulations and field measurements indicate that increasing albedo and vegetation cover can be effective in reducing the surface and air temperatures near the ground.

One of the main goals of the demonstration buildings within the FP7 "School of the Future" project is the improvement of the indoor environment quality (air, daylight, acoustic, thermal comfort) with impact on the pupils' performance to be analysed by short-term measurements and questionnaires. This report forms the basis of the evaluation of the indoor enviroment before and after the refurbishment of the 4 demonstration buildings in Germany, Italy, Denmark and Norway.
