Special Issue Information

Dear Colleagues,

Due to the enormous energy and water demands from the rising number of buildings today, the development of biological coatings for buildings (biological concrete, green roofs and walls), which mainly reduce energy and water consumption, has become very attractive to government, industries, and scientists worldwide. For example, green roofs, multilayer coatings used on top of buildings, not only have the potential of increasing a building's thermal inertia but also to capture rainwater for reuse, this technology also can reduce the urban heat island effect, urban run-off water volumes, and noise and air pollution. However, in spite of the described benefits, the use of these technologies is still limited due to high investment and maintenance costs, and also to the lack of detailed technical information on the proper design and construction of these building coatings. Therefore, this Special Issue aims to provide better comparisons and assessments of the application potentials of different biological coating technologies on buildings. In particular, the topics of interest include, but are not limited to, the following aspects:

  • Mechanical, Thermal and Hydraulic Performance of Biological Coatings,

  • Modeling of Biological Coatings,

  • Life Cycle Assessment of Biological Coatings,

  • Construction of Biological Coatings and

  • Novel Biological Coatings.

Abstract
Use of photocatalytic paint-like coatings may be a way to protect building materials from microbial colonization. Numerous studies have shown the antimicrobial efficiency of TiO2 photocatalysis on various microorganisms. However, few have focused on easy-to-apply solutions and on photocatalysis under low irradiance. [...] Read more.
Use of photocatalytic paint-like coatings may be a way to protect building materials from microbial colonization. Numerous studies have shown the antimicrobial efficiency of TiO 2 photocatalysis on various microorganisms. However, few have focused on easy-to-apply solutions and on photocatalysis under low irradiance. This paper focuses on (a) the antibacterial properties of a semi-transparent coating formulated using TiO 2 particles and (b) the microscopic investigations of bacterial biofilm development on TiO 2 -coated building materials under accelerated growth conditions. Results showed significant antibacterial activity after few hours of testing. The efficiency seemed limited by the confinement of the TiO 2 particles inside the coating binder. However, a pre-irradiation with UV light can improve efficiency. In addition, a significant effect against the formation of a bacterial biofilm was also observed. The epifluorescence approach, in which fluorescence is produced by reflect rather than transmitted light, could be applied in further studies of microbial growth on coatings and building materials.

Open AccessFeature PaperReview Cellulose Aerogels for Thermal Insulation in Buildings: Trends and Challenges

Abstract
Cellulose-based aerogels hold the potential to become a cost-effective bio-based solution for thermal insulation in buildings. Low thermal conductivities (<0.025 W·m−1·K−1) are achieved through a decrease in gaseous phase contribution, exploiting the Knudsen effect. However, several challenges need to [...] Read more.
Cellulose-based aerogels hold the potential to become a cost-effective bio-based solution for thermal insulation in buildings. Low thermal conductivities (<0.025 W·m−1·K−1) are achieved through a decrease in gaseous phase contribution, exploiting the Knudsen effect. However, several challenges need to be overcome: production energy demand and cost, moisture sensitivity, flammability, and thermal stability. Herein, a description and discussion of current trends and challenges in cellulose aerogel research for thermal insulation are presented, gathered from studies reported within the last five years. The text is divided into three main sections: (i) an overview of thermal performance of cellulose aerogels, (ii) an identification of challenges and possible solutions for cellulose aerogel thermal insulation, and (iii) a brief description of cellulose/silica aerogels.
