“…The operational phase essentially limits the theoretical model of conceptualising a zero-carbon building. Growing awareness of conducting life cycle assessments assists in elaborating boundaries related to policy implementation, geographical conditions, climatic diversity, sectoral density, and others [61][62][63]. These interactive boundaries conclude that zero-carbon is a diversified complex techno-social system without any specific system boundary.…”

This study aims to comprehensively depict a thematic evaluation within the context of carbon-neutral buildings over this century at variable time phases (2000–2008, 2009–2016, and 2017–2023). The overarching objectives of this study are delineated into three (3) contexts. Firstly, a bibliometric network encompassing influential research documents, authors, prominent journals, organisations, and countries is erected in pertinent fields. Secondly, significant terms are extracted from the scientific literature to exhibit co-occurrence patterns. Finally, an analysis of the evaluative clusters across variable phases was conducted to ascertain their intricate interrelations. The software tool VOSviewer Version 1.6.19 successfully achieves the initial objectives by visualising networks based on co-authorship, citations, co-citations, and bibliographic coupling. The ultimate goal of this research is fully realised through the application of the Science Mapping Analysis Tool (SciMAT), Version 3, which facilitated the evaluation of diverse clusters, phases, and thematic domains. The findings from the initial stages of research conducted on carbon-neutral buildings primarily revolve around energy-savings measures, environmental impacts, and the pursuit of energy-efficient design. As the research progressed into subsequent phases, the scope of inquiry broadened into specific themes, such as (1) optimisation, (2) retrofitting, (3) transitioning, and exploring (4) phase change materials (PCMs). Moreover, the areas of study continued to expand by developing diverse scenarios, algorithms, and digital twin technologies. The graphical representations of the strategic diagrams, evaluation areas, and cluster networks are a valuable resource for practitioners and policymakers, offering valuable insight and understanding of the multifaceted landscape of thematic evaluation in carbon-neutral buildings, thus facilitating further investigations and informed decision making.

“…In addition, earthen construction demonstrates thermal efficiency and high thermal comfort standards, especially in climates that have significant temperature variations between day and night [ 35 , 36 ]. Thermal behaviour, due to the high thermal inertia, can also be exploited in cold environments by providing a mass wall within an insulating envelope so that it can store and retain heat within the building and release it slowly during colder hours [ 36 , 37 , 38 , 39 , 40 ]. This aspect could bring many benefits in trying to decrease indirect emissions from the construction sector.…”

The fight against climate change has delineated new objectives, among which one of the most crucial is the replacement of high-energy-intensity materials in the construction sector with more sustainable and thermally efficient alternatives to reduce indirect emissions. Consequently, the thermal properties of materials assume fundamental importance. In this regard, the large-scale use of earth represents a promising option, not only due to its widespread availability but especially for its minimal embodied energy. However, to enhance its durability, it is necessary to stabilize the mixtures of raw materials. This study analyzes experimental systems based on earth stabilized with bio-based polymers to evaluate their thermal properties and how these vary depending on the selected mix-design. The experimental measurements showed thermal properties comparable to conventional materials. As expected, thermal conductivity increases when porosity decreases. The minimum value is equal to 0.216 W/m·K vs. a porosity of 43.5%, while the maximum is 0.507 W/m·K vs. a porosity of 33.2%. However, the data obtained for individual systems may vary depending on the topological characteristics, which were analyzed through a model for granular materials. The modeling suggests correlations between microstructures and thermal behaviour, which can be useful to develop tools for the mix-design procedure.

“…This requires the control of building information in relation to new and refurbished elements. The number of existing studies [27][28][29] that focused on the application of the life cycle approach to building refurbishment in BIM remains limited and includes the assessment of the economic and/or environmental dimension(s), without considering the social dimension (S-LCA). For example, Dauletbek and Zhou [27] focused on the refurbishment of an existing residential building using BIM-enabled LCA and simplified LCC "considering environmental compatibility, energy efficiency, and profitability based on real construction and energy consumption data".…”

Development of a Plug-In to Support Sustainability Assessment in the Decision-Making of a Building Envelope Refurbishment

Existing studies provide evidence that buildings and the construction sector are the largest consumers of natural resources and carry the greatest responsibility for greenhouse gas emissions. In order to reverse this situation, future challenges involve utilising the lowest amount of resources possible. To this end, building refurbishment has become a crucial strategy, given its potential to improve operational energy efficiency and to extend the life span of existing building stock, thereby reducing the environmental impact while also providing social and economic benefits to our cities. Life cycle sustainability assessment (LCSA) has become one of the scientific community’s most widely recognised methodologies for the evaluation of the social, economic, and environmental dimensions (triple bottom line), as it assesses sustainability using quantitative metrics. However, the implementation of this methodology to support the refurbishment process at the project stage in building design tools, such as BIM, remains scarce. One of the main obstacles lies in the difficulties of accessing building information, given that the system boundaries only cover new materials and products. Hence, this study proposes a BIM plug-in developed to support multi-dimensional building material selection in the early design steps based on the LCSA of a building during the refurbishment stage and validates its application in a case study. The results show the viability of using this tool during the early design stages and demonstrate the consistency of the results for evaluating various material and product alternatives for the refurbishment of the envelope system of a multi-family residential building. This study contributes towards the integration of decision-making by providing real-time assessment of a building envelope.
