“…Table 6 shows a summary of the calculation tool, which includes the resistances of the systems, their transmittances, insulation thicknesses, conductivities and the data on energy consumption per year, measured in kWh/m 2 , obtained through the Design Builder simulator and the consequent comparison with the increase in energy consumption with respect to the baseline, in absolute and percentage values, for each system. It can be seen that all the construction systems with fiberglass insulation are the ones that result in lower energy consumption per year, combined with the lower thickness of insulation required, without reaching the same energy efficiency of the baseline demonstrated in previous works [14,42].…”

The recent IPCC 2023 report reiterates that humans are responsible for global warming over the past 200 years, causing a rise in temperature of 1.1 °C above pre-industrial levels, urging the implementation of mitigation options, especially in the building energy sector. One strong mitigation strategy is designing and building net zero energy buildings (NZEB), although their implementation faces challenges such as opposition to change, especially in tropical countries with traditional and conservative design and construction practices. This paper uses data from a pilot NZEB Laboratory building at UCA, El Salvador, and details its results by comparing different construction system scenarios. The present work presents the results of the Life-cycle assessment (LCA) in three popular construction systems in El Salvador, comparing them with the baseline of its current operation, through 3 iterative calculation tools: structural, thermal and carbon footprint estimation, managing to visualize important findings on how vernacular systems could meet the NZEB performance with added insulation in the structural walls. In addition, a triple-axis sustainability analysis (environmental, economic and social) is conducted using the weighted criteria matrix, which provides nuanced results, such as the proportional share of embodied carbon between the proposals, there is not much difference between the results of the proposed systems, but compared to the baseline, the proposals represent a significant increase of more than 50%. Our results show that in this context, the scalability of NZEB buildings is feasible for different construction systems, paving the way for a progressive and incremental.

Net zero energy building design methodologies include integrative approaches and numerical tools to provide optimal performance and cost-effective results. Team integration, characterized by knowledge transfer between disciplines, has yet to be quantified for the design processes of these buildings. This article proposes a specific methodology for designing net zero energy buildings, tested through a case study design process conducted in an academic setting at Universidad Centroamericana in El Salvador, with the participation of students and faculty members. Through a survey, interdisciplinary knowledge transfer between team members was measured. We found that, without additional instruction, team participants outperformed a control group without project involvement by 16.4% (P < 0.002, t-test) in terms of interdisciplinary knowledge. This result implies that designers acquire new knowledge from other disciplines by interacting and solving design problems, although such acquisition is not uniform between disciplines. Remarkably, results show that the disciplinary groups that acquired the most knowledge about each other are Mechanical Engineering students and Architecture students. These results help us understand how to improve the design process, limit boundaries for disciplinary interactions, and determine which specific knowledge gaps to target per discipline in engineering and architecture education.
