In this issue, Pokhrel et al. publish an intriguing study from the Nepal–India border region that calls our attention to both what it shows and what it hides.1 This case–control study suggests an almost 2-fold risk for cataract related blindness among women using solid fuel unvented stoves. This risk gradient is similar to the one described between smokers and non-smokers.2,3 As in many economi...

Information accessibility on World Wide Web (WWW) still remains to be a complex issue for blind users as majority of websites are invaded by contents, both non-visual (audio) and visual (video & images). Accessibility measures in terms of a usable and blind-friendly website should be made available to blind users. A particular area that can be improved on is the e-Business segment for blinds. E...

This paper describes CFD modelling of Double Skin Façades (DSF) with venetian blinds inside the façade cavity. The 2-D modelling work investigates the coupled convective, conductive and radiative heat transfer through the DSF system. The angles of the venetian blind can be adjusted and a series of angles (0, 30, 45, 60 and 80 degrees) has been modelled. The modelling results are compared with t...

Adaptive building envelope technologies can increase the energy efficiency of buildings. facades be controlled automatically and respond to environmental changes. There is no standard method for evaluating control strategies adaptive façade elements, particularly dynamic shadings. Therefore, ISO/DIS 52016–3 recommended different default compare use various variants. presents procedures consider...
