“…In addition, by enhancing the thermal The ability to take precise measurements of the appropriate thermal performance is essential to understand and improve the thermal efficiency of this new 3DPC technology. The thermal performance of the exterior walls greatly influences the energy consumption of buildings and consequently their efficiency, as well as their emission of greenhouse gases [2,29]. In addition, the overall energy performance of a structure depends on external walls and their insulating value, and represents approximately 25% of the total heat loss [3].…”

“…While energy-saving building features have been integrated into the design of 3DPC elements, there has not been a systematic study on the energy efficiency of 3DPC buildings. Pessoa et al [29] conducted a systematic literature review to identify the key innovations made so far in 3DPC technology and its applicability in the construction industry, with specific attention being given to the thermal efficiency. Alkhalidi and Hatuqay [31] investigated and developed energy-efficient and low-cost residential 3DPC elements that could be accomplished through a green and sustainable method.…”

Three-dimensional-printed concrete (3DPC), which is also termed as digital fabrication of concrete, offers potential development towards a sustainable built environment. This novel technique clearly reveals its development towards construction application with various global achievements, including structures such as bridges, houses, office buildings, and emergency shelters. However, despite the enormous efforts of academia and industry in the recent past, the application of the 3DPC method is still challenging, as existing knowledge about its performance is limited. The construction industry and building sectors have a significant share of the total energy consumed globally, and building thermal efficiency has become one of the main driving forces within the industry. Hence, it is important to study the thermal energy performance of the structures developed using the innovative 3DPC technique. Thermal characterization of walls is fundamental for the assessment of the energy performance, and thermal insulation plays an important role in performance enhancements. Therefore, in this study, different wall configurations were examined, and the conclusions were drawn based on their relative energy performance. The thermal performance of 32 different 3DPC wall configurations with and without cavity insulation were traced using validated finite element models by measuring the thermal transmittance value (U-value). Our study found that the considered 3DPC cavity walls had a low energy performance, as the U-values did not satisfy the standard regulations. Thus, their performance was improved with cavity insulation. The simulation resulted in a minimum thermal transmittance value of 0.34 W/m2·K. Additionally, a suitable equation was proposed to find the U-values of 100 mm-thick cavity wall panels with different configurations. Furthermore, this study highlights the importance of analytical and experimental solutions as an outline for further research

“…In previous investigations, insulation material has been included in the wall system, as is the case in the study of Kaszynka et al [34], which used mineral wool and polyurethane foam between the 3D printed wall layers. Moreover, other techniques included thermal material in the internal spaces of the printed element [35,36], similarly to the proposed solution. Indeed, in the current research, the block is enterally prefabricated, placing the insulation panel immediately after the print in a specifically designed space (before the assembly in situ).…”

The Fourth Industrial Revolution represents the beginning of a profound change for the building sector. In the last decade, the perspective of shapes, materials, and construction techniques is evolving fast due to the additive manufacturing technology. On the other hand, even if the technology is growing fast and several 3D printed buildings are being developed worldwide, the potential of concrete 3D printing in building prefabrication remains unexplored. Consequently, the application of new digital fabrication technologies in the construction industry requires a redesign of the construction process and its components. This paper proposes a novel conception, design, and prototyping of a precast building envelope to be prefabricated with extrusion-based 3D concrete printing (3DCP). The new design and conception aim to fully exploit the potential of 3D printing for prefabricated components, especially in terms of dry assembly, speed of implementation, reusability, recyclability, modularity, versatility, adaptability, and sustainability. Beyond the novel conceptual design of precast elements, the research investigated the 3D printable cementitious material based on a magnesium potassium phosphate cement (MKPC), which was devised and tested to ensure good performances of the proposed component. Finally, a prototype has been realised in scale with additive manufacturing technology in order to verify the printability and to optimize the extruder path. This study leads us to believe that the combined use of prefabricated systems, construction automation, and innovative materials can decisively improve the construction industry’s sustainability in the future.

“…Finally, an area that certainly requires much more attention is the thermal behaviour of 3D-printed buildings. With Europe moving towards zero-energy buildings, new 3DP structures must fit within these requirements, something that can only be achieved with extensive research on thermal behaviour and design optimisation [59,60].…”

The main goal of this work is the analysis of potential energy and green benefits of 3D printing on building construction. Current literature reports a considerable number of benefits for 3D printing, namely, reduction of material use, lower operational costs and time-saving. The authors also mention design freedom, higher efficiency, productivity and quality. This work presents the latest developments in 3D printing in civil engineering, namely, a review of the last 3D printing projects and the limitations of construction 3D printing with a focus on large-scale applications, technology costs, mix development and optimisation and thermal behaviour.
