The focus of this review is on natural ventilation strategies and systems, highlighting design features and associated research. It outlines relevant papers dealing with: the main elements of natural ventilation research; the fundamental equations, driving forces and associated factors; the design and utilisation of windows, purpose provided openings, passive stacks and advances natural systems, with any design guidance where applicable; and case studies showing where such systems can be effectively installed, e.g. industrial buildings and libraries.
Patrick Waterfield, Energy Consultant with the EDAS Northern Ireland Regional Centre, examines an issue central to the energy performance of school buildings and also looks at an innovative fabric - Transparent Insulation Material.
New Best Practice programme publications from the Energy Efficiency Office provide the building industry with guidance on construction design for well insulated new houses, writes Peter Barton-Wood, BRECSU
Indoor radon concentrations, radon emanation rates from building surfaces, radioactivity contents of building materials and the indoor gamma dose rates for Hong Kong are all in general higher than values obtained elsewhere. An interesting phenomenon has been noted that the values of indoor radon concentrations and radon emanation rates from building surfaces in Hong Kong tend to decrease with the age of the buildings, while the absorbed gamma dose rate remains about the same.
