Abstract: When renovating buildings, it is essential to have detailed discussions with the investor at the beginning of the refurbishment process to enable sustainable and meaningful development. People often talk about energy-saving technologies in building refurbishments and their impact on the environment. Pairwise comparisons and utility analyses provide an excellent tool for influencing the materials used, their properties, and availability, thereby reducing emissions and negative environmental impacts. Building physics calculations of insulating materials are crucial in refurbishment projects, but it is equally important to present the various criteria to the investor. For instance, an optimal insulation thickness with a suitable insulation value can be considered economical, leading to fewer transports or the use of better technologies during transport and processing, which results in lower emissions. Recycling building materials is another aspect that should be considered, and the investor can control the weighting. The investor can easily recognise which decision impacts the result and how negative environmental influences can be minimised. This research report examines the mutual influences of ecological and economic aspects in the refurbishment of residential buildings. The method of pairwise comparison with benefit analysis is recommended, as it is related to problem detection and provides an evaluation of both positive and negative preferences. A data analysis over an extended period is recommended to optimize future refurbishments, and a target/actual state must be documented. From this, three main characters can be developed. Firstly, conditions or urban planning regulations and directives, such as minimum standards for windows (wood) or insulating materials for facades or roofs, can exert control and influence. Secondly, focus on tax aspects such as subsidies or grants. Thirdly, advice for investors can provide a plausible and understandable explanation of the basis for the decision based on the requirements, provisions, and tax aspects.
