ANALYSIS OF LINEAR THERMAL TRANSMITTANCE OF A SIMPLE BALCONY THERMAL BRIDGE
BOOK OF PROCEEDINGS XIII (2018), 2017 <p>The linear thermal transmittance of a simple balcony thermal bridge with a uniformbalcony slab and wall was analysed. In a five-parameter model (thickness, length andthermal conductivity of a balcony slab; thickness and thermal conductivity of an adjacentwall), it was found that the length of the balcony slab does not influence the ...

In Situ Thermal Transmittance of Case Studies in Dublin. [PDF]
, 2016 Thermal transmittance (U-values) of exterior walls represent a source of uncertainty when estimating the energy performance of dwellings. It has been noted in research that the standard calculation methodology for thermal transmittance should be improved.

Assessment of the thermal transmittance in ventilated windows
, 2014 The aim of this paper is to analyze the performance of thermal transmittance of a dynamic glazing system in the real conditions of work. The thermal transmittance of an envelope component, opaque or transparent, is not a constant physical quantity but it depends on the different intrinsic characteristics of the constituent materials.

An examination of the thermophysical nature of solar-control films using an illuminated hot box and computer based simulation modelling techniques [PDF]
, 1994 Solar-control films are increasingly being retrofitted to the windows of buildings as a means of reducing solar gain. At present, there is a dearth of information concerning how these films effect the thermal comfort of occupants within buildings where
