This paper reports on an experimental investigation on the effects of air gap, wind and walking motion on the thermal properties of traditional Arabian thawbs and Chinese cheongsams. Total thermal resistance (It) and vapour resistance (Re) were measured using the sweating fabric manikin – ‘Walter’, and the air gap volumes of the garments were determined by a 3D body scanner. The results showed ...

current standards for indoor comfort are based on studies of adults, but they also apply tochildren, even though children differ in terms of metabolic rates, clothing types, activity levels, and preferences in space arrangement. children are also more sensitive to a range of environmental factors, they are usually unable to interact with their environment, and they accept indoor conditions pass...

Using thermal insulation materials to reduce energy loss in buildings is a key action. For reducing the building’s use, firstly, internal unheated spaces (attics, cellars) should be insulated, followed by of external walls, and changing doors windows. Finally, building can completed with renovation/maintenance its service systems. Newly designed constructed are subject increasingly strict regul...

Abstract Foams are mainly composed of dispersed gas trapped in a liquid or solid phase making them lightweight and thermally insulating materials. Additionally, they applicable for large surfaces, which makes attractive thermal insulation. State-of-the-art foams made synthetic polymeric materials such as polystyrene. This work focuses on generating foam from surfactants renewable lignocellulosi...
