“…State of the art FPC colour coatings for the cover are reviewed in Section 4.1. Schüler et al (2005a) achieved s values of 0.9 and 0.84 for yellow and blue colour coatings respectively. Such adaptations to the cover result in daily efficiency drops of 4% (yellow coating) and 9% (darker blue coating) for the FPC based STF considered here.…”

“…yellow) achieved a greater figure of merit, M, than darker colours (e.g. blue) when applied to the cover of solar thermal collectors (Schüler et al, 2005a(Schüler et al, ,b, 2006. However, the figure of merit is not truly indicative because the solar reflectance of the glazing is the important parameter in terms of efficiency.…”

Plant tissues include leaves, flower petals, and fruits. These can provide us with variety of design inspirations. Biomimetics allows us to learn from nature and transfer the knowledge we gain from studying sophisticated and amazing biological structures, materials and processes to engineering and the arts. The microstructures of morphology and anatomy of plant tissue have potential applications in technology through bioinspired design, which can mimic the properties found in nature or use them as inspiration for alternative applications. Many applications have been developed as a result of studying physical properties of plant tissues. Structural colours, for example, have been applied in the design of thin films both with regard to single or multilayer thin film interference, scattering, and diffraction gratings. Iridescent, metallic, or greyish colouration found naturally in plants is the result of physical structures or physical effects and not pigmentation. Phenotypical appearance of plants with structural colouration in tropical Malaysia is correlated with environmental parameters such as location (shady understory rainforest, sunny conditions) and altitude (highlands, lowlands). Various examples of bioinspired technical innovations with structural colours highlight the importance of inspiration by structural colours in living nature.

One main barrier to the acceptability of façade use of solar thermal collectors is their black appearance and the visibility of piping or absorber irregularities through the glazing. To facilitate façade integration, a project was set up to develop selective filters reflecting only a small part of the solar spectrum in the visible range while letting the rest of the radiation heat the absorber. These filters were successfully produced and, combined with a diffusing glass treatment, have achieved the desired masking effect with minor impact on the collector efficiency (less than 10%). Glasses of various colours combined with several diffusing finishing (acid etching, structured glass etc…) can be produced that are able to hide the absorber. Such glazings will allow the use of the same product both in front of façade areas equipped with solar absorbers (as collector external glass) and in front of the non exposed areas (as façade cladding), opening the way to a broad variety of active façade designs. The active elements can then be positioned at will on the exposed areas, and their quantity determined only by thermal needs. By freeing the dimension of the façade area that can be clad with this glazing from the thermally needed surface for collectors, a major step to help architects use solar thermal on facades has been taken.
