This work presents the implementation of Visible Hyperspectral Imaging for the in-situ analysis of glass chromophores in two glass windows from the Casa-Museu Dr. Anastácio Gonçalves (Lisbon, Portugal). The measurements were taken inside the building using natural sunlight as the illumination source. In addition, advantages and disadvantages of the followed methodology are discussed.The Dining Room glass window presents glasses colored in bulk with iron, manganese, cobalt, copper, and chromium; silver staining was also detected and was used to create the yellow and orange colors. The Atelier panel was produced with uncolored glasses painted with grisaille and enamels; the chromophores identified are similar to the species identified in the Dining Room panel.

Purpose -The use of organic phase change materials microcapsules (mPCM) has been gaining ground in technical textiles and clothing as a temperature regulating medium and hence a means of keeping the body at a comfortable temperature when wearing impermeable protective clothes. However, for such applications as fire fighter's protective clothes, the standards require that all the material composing the material be fire resistant. The purpose of this paper is to produce a lining containing fire resistant microcapsules of PCM without using flammable binders. Design/methodology/approach -This work tests other ways of fixing mPCM to the fibres with a lot less binder present. Washfastness is evaluated in SEM photographs and by weight. The thermal effect is evaluated in a prototype plate calorimeter. Findings -This method is first tested for fixing mPCM but the non-woven still does not pass the test according to the standard EN532. Microcapsules are alternatively fixed with MF resin, non-flammable, and by applying flame retardant recipes it is possible for the samples to pass the test. Research limitations/implications -Since the amount of flame retardant necessary for the mPCM to stand the test, and the resin to thermo fix it is very high, the material becomes unacceptably stiff.Originality/value -Based on a new approach where reactive microcapsules without any binder are used, it is possible to use a lot less flame retardant and resin, and the material is resistant to the standard EN532. In this standard the material has to resist washing and still be flame retardant.

This work presents the results of the evaluation of two Art Nouveau glass windows from the Casa-Museu Dr. Anastácio Gonçalves (Lisbon, Portugal) with IR-thermography during the summer solstice. According to the measurements, the surface temperature of glass depended on the outdoor environmental temperature and, mainly, on the direct solar radiation. Colored glasses presented a higher surface temperature due to the absorption of their chromophores at near-IR wavelengths. Enamels and grisailles showed higher surface temperatures than their support glasses due to both their chemical composition and color. The protective glazing, with small slits in one of the window panels, induced a hot-air pocket in its upper part due to the insufficient ventilation.

Incorporating phase change materials (PCM) in plasters is an effective solution both for more efficient use of energy and its consumption reduction, because it allows the use of free energy in the environment, by latent heat storage. As PCM has not binder properties, it is expected to decrease mechanical properties of the final mortar. Also the density of the mortar decreases due to PCM lighter specific weight. In order to be used as a final coat for wall plastering, it must verify the requirements of the respective European Standard. This paper presents the results of the composition development and mechanical properties (flexural, compressive and adhesive strengths) testing and validation of three different gypsum mortars, in order to select the appropriate one for thermal testing in test cells. The results show that the effective decrease in the studied characteristics of the mortar does not inhibit the use for plastering, as requirements are achieved by the three studied compositions.
