In recent years photovoltaic technology, the conversion of sunlight to electricity, has made great technological strides.
But in the main, solar photovoltaics, where utilised, are often applied as an 'add on' solution to buildings, an afterthought, and in a way that may be efficient, but is not always a testament to good design.
There's no doubt that the uptake of the technology by architects and engineers could be improved by more sensitive integration into buildings – by replacing glazing, cladding, roofing or shading systems, for example, and offsetting the cost of such materials.
This programme looks at the ways of incorporating photovoltaics into buildings and discusses the wider implications with regard to embodied energy – and economics.
