Efficiency analysis of flat plate collectors for building facade integration

A theoretical approach has been used to evaluate the performance of facade integrated solar collectors based on the physical collector parameters such as absorber plate absorptance, transmittance of the glazed cover plate and insulation thickness. A 1D steady state model, based on the Hottel Whillier Bliss equation, was employed to determine the effect of changing parameters to meet façade integration criteria.

Voir Hitler en peinture / On Seeing a painting of Hitler
The article “Voir Hitler en peinture” (literally “On Seeing a painting of Hitler”) focuses on a painting by Oliver Jeffers entitled “Ginger Hitler”. This article suggests that, whatever Jeffers’ intent and inspiration were, his painting “defamiliarizes” Hitler (V. Shklovsky) and forces us to look at him afresh. For decades, Hitler has been demonised and dehumanised; yet, however unsettling this may be, he was human. As Professor Richard Evans, a leading expert in the history of Nazism, put it recently: “Viewing Hitler as a human being, which he undoubtedly was, is more challenging to our understanding, surely, than simply writing him off as a cartoon villain” (The Guardian, 30/04/2015).
