Special Issue Information

Dear Colleagues,

We are soliciting manuscripts for a Special Issue of the Energies Journal on “Nanotechnology and Nanomaterials for Low-Energy-Consumption Buildings”. With the arrival of nanotechnology as a new scientific discipline, science’s cutting edge now views reality more deeply, extending into dimensions at the subatomic level. This new paradigm of scientific thinking allows us to believe that a better understanding of Nature is at our fingertips. With the help of nanotechnology and nanomaterials, we propose to explore the possibility of minimizing the impact of urban growth on the environment and promoting the efficient use of energy in existing or future buildings. The production of thermally insulating materials based on aerogels modified with nanomaterials is now a reality. These new compounds provide a level of thermal insulation that is 10 times higher than that of a conventional material, and are already being incorporated into building windows in order to reduce heat loss. Other novel thermally insulating composites based on nano/micro-PCMs and TiO2 nanoparticles are beginning to emerge for the purpose of intelligent temperature regulation and more efficient use of solar energy. Even more promising is the development of an adequate combination of cellulose nanofibers, graphene oxide, and sepiolite nanorods to produce super-insulating material, taking advantage of the specific capacities of each component to find interesting synergies that result in an efficient use of energy. There are many more possibilities for new synergies, and, thus, for nanomaterials to make further contributions to the building industry with the aim of achieving sustainable development and energy efficiency.

Topics of interest to this Special Issue include the incorporation of nanotechnology and nanomaterials into conventional building materials applied in any field related to energy consumption, including conventional and renewable energy generation. Topics of particular interest include, but are not limited to:

  • nanomaterials for improving the application of solar and other renewable energy sources in buildings;
  • thermal energy storage and thermally active building materials modified with nanostructures;
  • nanotechnology for controlling the performance of indoor thermal systems;
  • new nanomaterials for buildings and their impact on energy consumption;
  • nanomaterial-based heat recovery systems in buildings;
  • synthesis of nanomaterials with improved thermal properties;
  • phase-change materials at the nanolevel;
  • solar thermal phase-transition technologies.

Due to the need of good thermal performance, external wall insulation (EWI) is usually made of materials that are not fire resistant and sometimes flammable. That restricts its application to a particular circumstance such as limited building height. Hence, a material with good thermal insulation and fire resistance performance would allow EWI to be more widely applied. This paper introduces a novel material: a silica-based aerogel porous board, which differs itself from mainstream products available in the market because of its outstanding properties, such as low density, high surface area, low thermal conductivity and superhydrophobicity. Herein, its thermal insulation and fire-resistant performance were tested and compared with commercial products. The cone calorimeter analysis results indicated that the aerogel porous board could improve the fire resistance performance. Moreover, the evaluation of thermal insulation performance suggested that the application of an aerogel porous board on the external stone wall of existing buildings can decrease the U-value by 60%. Through the detailed insight into the case-study, it is quite clear that the carbon impact of building stock could be greatly reduced by means of a coherent set of building envelope retrofitting actions based on this innovative heat insulation material, without compromising the fire safety.

The 2030 Agenda and Sustainable Development Goals (SDG) are both an engineering challenge and an opportunity. Clean energy (SDG 7), sustainable cities and communities (SDG 11), and climate action (SDG 13) represent an effort to manage, plan, and develop our buildings and infrastructure. The purpose of this study is to contribute to this challenge by analysing nanomaterials in marine environment structures, both urban and maritime. To do this, we have analyzed different regulations of concrete properties in various countries, defining the characteristics of the cement, coating, water/cement rating, and chloride effect; the difference in durability based on conventional reinforcements and nanomaterials; and use on highly sensitive elements, buildings in marine environments, rubble mound structures, crown walls, and gravity-based foundations for wind power facilities. Division into overhead, underwater, or splash zones entails the use of epoxy resins or silica fume matrices in percentages far below ten percent. Using the most exposed and unfavorable structures, conclusions of application to buildings are established based on the recommendations in maritime engineering most exposed to the actions of the waves. The study concludes with recommendations regarding the durability, increased lifespan, and use of new materials in infrastructure elements in highly adverse marine environments. Full article
