Special Issue Information

Dear Colleagues,

The Guest Editors are inviting submissions to a Special Issue of Sustainability on the subject area of “Sustainable Building Materials and Energy-Efficient Buildings.” As known, the construction sector has a great responsibility in energy and natural resources consumption and in annual production of waste. Innovative and more integrated solutions to contemporary buildings are needed to preserve our environments by systemic strategies aiming to reduce impacts and consumptions.

This approach needs to be pursued both in production phase (using low-embodied energy base materials, as natural or recycled ones, according to the circular economy approach), construction phase (promoting the use of low energy demanding construction technologies and building processes), use phase (through the refurbishment and retrofitting of existing buildings toward the minimization of their energy needs and improvement of thermal performance of the envelope, designing highly energy-efficient buildings by passive and active strategies) and end-life phases (advancing in zero-waste and low carbon footprint materials, technologies and processes).

In this regard, the Special Issue aims to answer several issues connected to the concept of sustainability in buildings, by exploring different aspects concerning building materials, construction technologies, hygrothermal and energy performances and indoor thermal comfort of the built environment. In addition, other issues regarding the influence of building materials on outdoor thermal comfort in urban areas and their environmental performance can be addressed. The presentation of comprehensive literature review, case studies, and development of new methodological approaches, based on experimental measurements and building energy analysis are warmly encouraged.

Topics of interest for publication include, but are not limited to:

  • Innovative and emerging bio-based, recycled, and waste-based building materials
  • Improvement of mechanical, physical, thermal performances of building materials
  • Durability of Bio-aggregate based building materials
  • Circular economy strategies for building sustainability
  • Life cycle sustainability assessment of building materials and technologies
  • Innovative technologies for low energy buildings
  • Advances in material and technology research and engineering
  • Eco-design and bioclimatic approach for buildings
  • Technical synergic solutions for improving thermal inertia, indoor thermal comfort and energy performance of massive and lightweight existing buildings
  • Active and passive strategies for designing high-energy efficient buildings
  • Zero energy buildings and passive houses
  • New approaches to sustainable production and building construction
  • Innovative procedures to assess building and construction materials’ sustainability
  • Urban materials and greening strategies for outdoor thermal comfort in densely built areas
  • Mitigation strategies of Urban Heat Island phenomenon

Looking Critically at Heat Loss through Party Walls

Heat loss through party walls to outside (not the neighbouring dwelling) has received considerable attention in the UK, and this was flagged as a serious omission from the UK Building Regulations in 2010-12. There was evidence of significant heat loss between adjoined terraced or semi-detached new homes, which was increasingly important as heat loss from other parts of dwellings was being reduced. As a result, Building Regulations were changed so that other parts of the building envelope had to be improved in new homes to compensate for heat loss through the party wall. However, this empirical work based on measuring heat loss through the party walls of 55 UK dwellings indicates that fears about high heat loss through party walls may have been exaggerated. While a minority of dwellings (less than 10%) do suffer from a “thermal bypass” through the party wall, for the vast majority of existing homes with party walls, heat loss through the party wall is minimal. There may be a case for revising UK Building Regulations to reflect this new evidence, and for re-directing the efforts aimed at reducing heat loss through party walls towards other opportunities to improve the energy efficiency of dwellings.

Prototyping of a Novel Rammed Earth Technology

Buildings of the future are called to meet increasingly high-performance requirements and to ensure adequate environmental sustainability of the production and construction chain. This issue has stimulated a keen interest in the use of natural materials in construction. Among these, raw earth has proved to be particularly interesting for its intrinsic availability, sustainability, and recyclability. In Europe, the spread of raw earth building technologies has often been hindered by the lack of specific legislation regulating its use for load-bearing structures, even if in many countries, it can be noticed a widespread and well-established constructive tradition. Some transoceanic research experiences attest that unfired earth can be used, together with different types of reinforcements, to create seismic-resistant buildings. After presenting a review of the main raw earth reinforced technologies, the present study focuses on a novel reinforced and modular rammed earth construction made with natural or recycled materials, developing a technology with low energy consumption and low environmental impact, specifically designed for areas with high seismic risk. In particular, the work presents the results of a prototyping procedure aiming at developing a new seismic-resistant construction system that combines rammed earth with timber reinforcement elements and nylon/polyester ropes. These elements have a dual function: (1) they are fundamental components of the construction process (as they integrate the formwork system), and (2) they act as seismic-resistant devices once the structure is completed. In line with the performance-based approach required by the construction sector, the study aims at defining a controlled and standardised supply chain for rammed earth construction. Full article

A new formulation to estimate the elastic modulus of concrete containing recycled coarse aggregate is proposed in this work using artificial neural networks (ANN) and nonlinear regression. Up to six predictors variables were used to training 243 ANN. The models were generated based on results obtained from experimental campaigns. Feedforward neural network and Levenberg–Marquardt back propagation algorithm were used for training the ANN. The best ANN was found with the architecture 6-4-2-1 (input -1st hidden layer -2nd hidden layer -output), attaining a root-mean-square error of 2.4 GPa associated with a coefficient of determination of 0.91. Once the ANN model was established, 46,656 concrete samples were created. These were employed to formulate the model using nonlinear regression. The developed model showed a highly efficient performance to predict the elastic modulus. Lastly, considering the parametric study conducted, the results pointed out that the approach can be applied to predict the concrete elastic modulus and can indicate better mix proportions for concretes containing natural and/or recycled coarse aggregates, enabling its use as a simulation tool in the development of engineering projects focused on durability and sustainability.

The sustainable reuse of the built heritage is one of the main challenges of our time. Religious heritage, in particular, requires strong survey strategies and analyses in order to achieve consistent approaches for the conservation and transmission of its value, both material and immaterial. The exploitation of the latter is underpinned by knowledge analyses, prior to the conservation actions, with a focus not only on the techniques of material restoration but also on the values that it represents for the territory and local communities. With this aim, three case studies in Southern Italy are here presented, that offer a good example of how ecclesiastical heritage, although vast and diffuse, is still an undervalued asset. By combining accurate knowledge and historical research in comparison with the residual performance of the buildings, the results aim to demonstrate how integrated knowledge strategies can pursue more conscious choices of new possible uses for abandoned religious heritage, resulting in preserve their memory and add value in terms of social sustainability.

More than 124 million tons of oranges are consumed in the world annually. Transformation of orange fruit generates a huge quantity of waste, largely composed of peels. Some attempts to reuse by-products derived from citrus waste have been proposed for energy production, nutrient source or pharmaceutical, food and cosmetic industries. However, their use in the building sector had not been researched. In this study, orange peels, in five different ratios, from 100% of wet peels to 75% and from 0% of dry peels to 25%, were submitted to a thermo-compression procedure. They were evaluated according to their physical (bulk density, water absorption, thickness swelling, surface soundness and thermal conductivity) and mechanical properties (bending strength and modulus of elasticity). The results showed that orange peels can be used as thermal insulation material. The addition of dried peels makes the structure of the board heterogeneous and thus increases its porosity and causes the loss of strength. Hence, the board with the sole use of wet peel, whose thermal conductivity is 0.065 W/mK while flexural strength is 0.09 MPa, is recommended. Full article

This paper aims to investigate the effect of fine recycled concrete powder (FRCP) on the strength of self-compacting concrete (SCC). For this purpose, a numerical artificial neural network (ANN) model was developed for strength prediction of SCC incorporating FRCP. At first, 240 experimental data sets were selected from the literature to develop the model. Approximately 60% of the database was used for training, 20% for testing, and the remaining 20% for the validation step. Model inputs included binder content, water/binder ratio, recycled concrete aggregates’ (RCA) content, percentage of supplementary cementitious materials (fly ash), amount of FRCP, and curing time. The model provided reliable results with mean square error (MSE) and regression values of 0.01 and 0.97, respectively. Additionally, to further validate the model, four experimental recycled self-compacting concrete (RSCC) samples were tested experimentally, and their properties were used as unseen data to the model. The results showed that the developed model can predict the compressive strength of RSCC with high accuracy. Full article
