“…Metallic cool coloured alternatives were developed with anodized aluminium and aluminium with reflective baked-on coatings in different shades of brown, with a solar reflectance up to 0.5 for a light brown samples, for instance (Ihara et al, 2016). Relevant for façade application is a study on the performance of mineral based coatings, even if limited to white samples (Kolokotsa et al, 2012). High solar reflectance and emissivity values were measured for renders, based on lime with additions of calcium carbonate powder, and for paints, based on lime wash or silicate minerals.…”

“…Therefore, many works focused on building materials for envelope application, deeply analyzing all of the aspect related to a particular or innovative technology used as a facade component. Kolokotsa et al [8] examined mineral-based coatings, assessing how they contribute to buildings' energy efficiency. After developing mineral-based samples, they assessed the optical and thermal properties of these components.…”

Integrated Thermal-Energy Analysis of Innovative Translucent White Marble for Building Envelope Application

Marble is a natural material, used in the construction field since antiquity. It has always been used to communicate monumentality and solidity. Nowadays new technologies permit marble to express new languages: particularly, translucent marble technology overturns the concept of solidity. The main issue to address is the lack of thermal-energy performance of such a thin stone layer as the only facade component. Conversely, Bianco Carrara and Statuario marbles, for instance, have intrinsic benefits as natural cool materials, due to their high solar reflectance and thermal emissivity. Thus, this paper analyzes the thermal-energy and environmental behavior of marble facade for a new designed building in New York City. An integrated analysis of the energy performance of the marble skin is performed through a preliminary experimental characterization, carried out for two different types of naturally white marble, for comparative purposes. Then, a dynamic simulation model of the building is developed to evaluate year-round benefits and drawbacks of the translucent marble envelope in terms of indoor thermal comfort and air-conditioning requirement. The analysis showed how the proposed marble facade is able to decrease the energy requirement for cooling up to 6%, demonstrating possible relevant perspectives for marble-based facades, even in energy-efficient buildings.

“…In fact, parallel to the concept of cool materials optimization [28], the appreciation of traditional techniques and natural local materials and technical elements, i.e., clay tiles, contributes to the purpose of providing important advantages from a global environment point of view [29][30][31], such as: low embodied energy, ability to regulate indoor humidity, reduced toxicity, and relatively low price [14].…”

Development of Clay Tile Coatings for Steep-Sloped Cool Roofs

et al. 2013

Most of the pitched roofs of existing buildings in Europe are covered by non-white roofing products, e.g., clay tiles. Typical, cost effective, cool roof solutions are not applicable to these buildings due to important constraints deriving from: (i) the owners of homes with roofs visible from the ground level; (ii) the regulation about the preservation of the historic architecture and the minimization of the visual environment impact, in particular in historic centers. In this perspective, the present paper deals with the development of high reflective coatings with the purpose to elaborate "cool" tiles with the same visual appearance of traditional tiles for application to historic buildings. Integrated experimental analyses of reflectance, emittance, and superficial temperature were carried out. Deep analysis of the reflectance spectra is undertaken to evaluate the effect of different mineral pigments, binders, and an engobe basecoat. Two tile typologies are investigated: substrate-basecoat-topcoat three-layer tile and substrate-topcoat two-layer tile. The main results show that the developed coatings are able to increase the overall solar reflectance by more than 20% with acceptable visual appearance, suitable for application in historic buildings. Additionally, the effect of a substrate engobe layer allows some further contribution to the increase of the overall reflectance characteristics.
