Special Issue Information

Dear Colleagues,

Currently, energy and sustainability are two of the major concerns of humankind. Given the relevant energy consumption share of the buildings sector, it is very important to search for innovative design solutions and for the optimal thermal performance of buildings in order to reduce energy bills and greenhouse gas emissions, while maintaining the comfort levels of the occupants. Additionally, given the environmental burdens of the construction sector, seeking more environmentally responsible processes and a more efficient use of resources is currently attracting more attention.

This Special Issue is dedicated to the analysis of the recent advances on the following topics: (1) the thermal behaviour improvement of a building’s elements (e.g., walls, floors, roofs, windows, doors, etc.); (2) energy efficiency in buildings; and (3) sustainable construction. All types of the following research approaches are acceptable: experimental, theoretical, numerical, analytical, computational, case studies, and their combinations. The main criteria for paper acceptance are academic excellence; scientific soundness; and the originality and novelty of applications, methods, fundamental findings, or experiments.

The Special Issue will include the following topics:

  • Thermal behaviour improvement of a building’s components (e.g., walls, floors, roofs, windows, doors, etc.);
  • Thermal bridges assessment and mitigation;
  • Energy efficiency in buildings;
  • Thermal inertia increase techniques (e.g., use of PCMs—phase change materials);
  • Building location and climate—air temperature, solar radiation, relative humidity, wind speed and direction, ground temperature, daylight hours, and so on;
  • Building envelope—air tightness, thermal insulation, glazed openings, shading, and so on;
  • Building services—appliances, illumination, heating, air-conditioning, ventilation, heat recover, hot water production, and so on;
  • Human factors—occupancy schedule, utilization type, internal heat gains, and so on;
  • Passive heating and cooling techniques—natural ventilation, solar heat gains, Trombe walls, ground source heat exchangers, and so on;
  • Renewable energy sources for building applications—solar collectors for domestic hot water production, photovoltaic solar panels, wind turbines, and so on;
  • Optimization of thermal behaviour and of energy efficiency of buildings;
  • Environmental life-cycle assessment of buildings and building components;
  • Life-cycle cost assessment of buildings and building components;
  • Building’s operational and embodied energy.

Building materials are responsible for significant CO2 emissions and energy consumption, both during production and operational phases. Earth as a building material offers a valuable alternative to conventional materials, as it naturally provides high hygrothermal comfort and air quality even with passive conditioning systems. However, disadvantages related to high density, conductivity, and wall thickness prevent its effective inclusion in the mainstream. This research explores enhancing the thermophysical properties of compressed earth blocks (CEBs) by using locally sourced natural materials. The study is framed in the Portuguese context and the natural materials involved are wheat straw (WS) as a by-product of wheat harvesting, cork granules (CGs) from bottle caps, and ground olive stone (GOSs) residues from olive oil production. Blocks were produced with different mixtures of these materials and the thermal response was examined in a hot box apparatus. Best results include a 20 and 26% reduction in thermal conductivity for mixtures with 5v.% CG and 10v.% GOS, respectively, and an associated reduction in bulk density of 3.8 and 5.4%. The proposed approach therefore proves to be effective in improving the key thermophysical characteristics of CEBs. The article includes a comparative analysis of the experimental data from this study with those from the literature. The study contributes to the growing knowledge of sustainable materials, providing insights for researchers and practitioners looking for innovative solutions for low-carbon and energy-efficient materials.
