Abstract: The analysis of the carbon footprint of buildings is a key tool for assessing the impact of different buildings on climate change. Several frameworks and methodologies are available to calculate the footprint of buildings, including standards and norms, Life Cycle Assessment (LCA), and dedicated software tools. The use of Building Information Modeling (BIM) programme for these calculations is both scientifically justified and very practical. This scientific publication focuses on the application of a BIM-based research methodology to analyse the carbon footprint of a single-family house. The research process included the following steps: (i) the design of a single-family house with masonry construction using Archicad 26, BIM programme, (ii) simulation of the building energy performance using the EcoDesigner Star plug-in, (iii) LCA using the plug-in for Archicad, (iv) preparation of a second model with timber-frame construction for comparison, and (v) comparative analysis of the single-family house models with masonry construction (building A) and timber-frame (building B). Analysis of the results highlights significant differences in CO 2 e emissions between buildings and the varying impact of individual elements on the total CO 2 e emissions of the buildings studied. Building A had significantly higher net emissions, amounting to 43,226.94 kg CO 2 e, in stark contrast to Building B’s significantly lower 13,522.13 kg CO 2 e. This discrepancy was also mirrored in the emission intensity, with Building A emitting at a rate of 281.06 kg CO 2 e/m 2 compared to Building B’s 96.72 kg CO 2 e/m 2 . These findings are relevant for future work on sustainable building design and construction aiming to minimise negative environmental impacts. The goal of minimising the cumulative carbon footprint of buildings is critical to achieve the Sustainable Development Goals and combating climate change.
