Design decisions made in the early phases of the design process have a significant impact on the eventual performance of the completed building. Currently, computer-assisted methods offer limited support during the crucial stages of creating, assessing and refining design variants. This paper presents an integrated framework combining computer-aided design processes and performance-based evaluation methods to support a non-linear, iterative design process. The framework integrates spatial metrics (e.g., layout and design similarity), structural metrics (e.g., feasible systems and material quantities) and environmental–energy metrics (e.g., heating demand) to provide transparent, quantitative and qualitative feedback for early-stage decision-making. Applying the framework allowed for the incorporation of structural, environmental and spatial assessments early in the process. The design assistance framework is graphically represented using business process model and notation (BPMN), which facilitates communication between process design and implementation. A real-world, mixed-use building scenario illustrates how the individual methods interact to streamline the decision-making process for architects. The framework guides the entire process, from design decisions to structural and performance-specific features, offering inspirational support for architects and practical assistance for structural engineers, sustainability experts and other professionals involved in early-stage building design.
Dynamic life cycle impact assessment (DLCIA) in a sustainable building planning process
Chujun Zong, Farzan Banihashemi, Werner Lang
Scientific Reports, 2025
Building sector significantly contributes to the anthropogenic environmental impacts. To promote sustainable construction, life cycle assessment (LCA) serves as a useful tool to quantify the environmental impacts of a building and suggest improvement solutions. It is widely acknowledged by various regional and international regulations and is mandated for new buildings in the European Union. While the conventional LCA often fails to capture the dynamics in a building’s life cycle, this study enhances the plausibility of building LCA by implementing a dynamic life cycle impact assessment (DLCIA) for a solid masonry building, evaluating improvement solutions across its product and End-of-Life (EoL) phases. Our DLCIA approach, aligned with Intergovernmental Panel on Climate Change Assessment Report (IPCC AR) 6, provides a transparent and clear calculation process of global warming potential (GWP) overtime and a comprehensible comparison with the conventional static calculation. We demonstrate that the dynamic GWP calculations based on the DLCIA approach are consistently 5–7% higher than static counterparts, successfully capturing the continuous decay of GHG emissions in the atmosphere and the environmental impact of each emission event. Applied to improvement solutions, this method guided strategies that achieved a 31.52% reduction in total GWP. Furthermore, integrating a dynamic circular recycling model into the improvement solutions in the EoL phases highlights the potential of combining multiple dynamic factors and critically discusses the concept of circular economy. To promote circular economy in construction, it is essential not only to improve the conversion rate of waste materials into compounds for virgin materials but also to explore cross-material recycling and recycling among multiple building entities. Future dynamic LCA (DLCA) studies should integrate DLCIA with other dynamic factors to enable more comprehensive and systematic assessments.
LCA-based calculation of GHG Protocol Scope 3: A bottom-up approach to determine GHG emissions of the construction activity of municipalities
Leander Präger, Jonathan Woytowicz, Roland Reitberger, Werner Lang
Building and Environment, 2025
Cities and municipalities worldwide have set the goal of climate neutrality and use the GHG Protocol as a common method for accounting. An analysis shows that their construction activities’ greenhouse gas (GHG) emissions, including those arising from the production, supply, and disposal of building materials, are currently inadequately reported in municipal GHG Protocols. Either these are not considered at all, or they are roughly calculated using a top-down approach, such as Multi-Region Input-Output analysis, based on monetary spending data and sector-aggregated GHG emission factors. This research uses Life Cycle Assessment (LCA) based on Environmental Product Declarations as a more accurate calculation method. It scales up the labor-intensive method from individual buildings to larger building portfolios by introducing a new scalable calculation method called “Tender-AI LCA”. It analyzes tender documents and uses artificial intelligence (AI) to determine GHG emissions. We showcase the accuracy and usage of “Tender-AI LCA”. The calculated GHG emissions of sample construction projects show deviations ranging from 85% to 149%, averaged over the study at about 106%, compared to conventional bottom-up calculations based on German standards. Applying the approach in a case study in Hanover, Germany, led to the calculation of 2,813 t CO 2 e from municipal building construction activities in 2023 and 3,662 t CO 2 e in 2024. Hence, “Tender-AI LCA” enables calculating GHG emissions according to the GHG Protocol using a bottom-up approach. It thus provides more accurate results than previous top-down approaches while being scalable and more time-efficient than conventional bottom-up calculations. • Methodology for calculation of construction activity for GHG Protocol. • Corporations and cities can use the approach for fast and precise calculation. • Reflect CO 2 e savings from sustainable materials better than spending-based methods. • Show how data management and processing of tender documents can be implemented. • Demonstrates an application in Hanover, Germany.
Life cycle cost analysis of urban trees: a case study of five cities in Germany
Doris Bechtel, Rebecca Amberger, Brigitte Helmreich, Sven Bienert, Werner Lang
Urban Forestry and Urban Greening, 2025
Trees in urban sites are a nature-based solution for mitigating local heat stress due to the tree's ability to provide shading, enhance evaporation, and increase biodiversity. In supporting well-being in the built environment, the goal of the European Green Deal emphasizes planting new trees; it does not address the protection of existing trees nor the quality of new plantings in response to climate change. Additionally, the economic benefits of urban tree protection have received less attention in research than new plantings. Hence, in several planning competitions, we developed cost benchmarks for six urban tree scenarios, focusing on realistic planning scenarios. We compared the life cycle costs, analyzing construction, maintenance, and end-of-life costs based on the German building cost index and variations in discount rates. Our 50-year life cycle cost assessment shows that preserving existing trees, including implementing tree protection measures, is more cost-effective than tree removal and replacement planting during the cycle. Furthermore, if new tree planting is required, planting in a green space is more than twice as cost-effective as planting in partially sealed areas. Planting in partially sealed areas is up to five times more expensive than preserving existing trees. When planting in sealed sites is unavoidable, the payback period of an optimized tree pit is after approximately 34 years, considering no discount rate. If a discount rate is included, a lower rate of 1.5% encourages planting in an optimized tree pit. Our benchmarks provide valuable insights for decision-makers to optimize tree management strategies for urban areas. This study encourages preserving urban trees and non-sealed locations to maximize long-term cost efficiency.

Multi-criteria decision-making for energy building renovation: Comparing exterior wall structures with the AHP, ANP, utility analysis, and TOPSIS
Kathrin Theilig, Michael Vollmer, Werner Lang, Jutta Albus
Building and Environment, 2025
Purpose: Improving residential building energy efficiency is crucial for reducing greenhouse gas emissions . Designing resource-efficient, nearly zero-emission renovations is complex. This study addresses the need for comprehensive frameworks to holistically evaluate building part renovation measures and to provide actionable guidance for strategic planning and implementation across the building life cycle, focusing on exterior walls. Four multi-criteria decision-making (MCDM) methods identify the most environmentally friendly alternative and are compared for rank similarities and decision-making applicability. Methods: The study follows a two-stage approach: (i) applying the Analytical Hierarchy Process (AHP), Analytical Network Process (ANP), Utility Analysis (UA), and TOPSIS to rank exterior wall alternatives regarding environmental impacts and circularity and (ii) comparing these methods using the Borda technique, based on correlation and standard deviation metrics and the Wojciech Sałabun (WS) coefficient. A qualitative assessment from a planner’s perspective is also included. Results: The results show that different MCDM methods consistently rank the most environmentally friendly renovations, offering clear guidance for strategic implementation. This offers actionable guidance for strategic planning and implementation. The top five alternatives remain consistent across all methods, with slight ranking variations. AHP ranked first by Borda scores, while UA leads by WS coefficient. Curtain walls with timber cladding emerge as the most sustainable choice, outperforming metal cladding and insulated composite structures. Conclusions: The AHP, ANP, UA, and TOPSIS support selecting environmentally friendly building parts. UA and TOPSIS, being more sensitive to emphasized criteria weighting and relatively more applicable in practice, are recommended for building parts’ decision-making.
Tree growth simulation in Geographic Information Systems: Coupling CityTree and ArcGIS for solar radiation analysis
Roland Reitberger, Vinayak Prem Kooniyara, Leila Parhizgar, Thomas Roetzer, Werner Lang
Sustainable Cities and Society, 2025
Cities must undergo a sustainable transformation as they rapidly expand with urban heat and CO 2 emissions increasing. Urban development with a detailed digital twin is crucial for managing this multilayered transformation. This paper proposes an approach to integrate urban tree growth in such digital twins. By coupling Geographic Information Systems (GIS) with a tree growth model our methodology predicts the growth of trees for 20 years. This allows the local assessment of future Ecosystem Services from trees and supports their long-term management. The CityTree model is used to simulate tree growth in a 500,000 m 2 case study area in Munich, Germany. The derived crown diameter and height increments are implemented in ArcGIS to assess the resulting impact on solar radiation. 20 years of tree growth reduced the solar radiation on the ground by 6.1%, whereas on the building roofs, the reduction was 1.0%. The increase in cooling energy due to tree growth exceeded the reduction of usable solar energy from buildings’ roofs by a factor of almost 50. The methodology for 3D tree growth projection in GIS saves monitoring resources for urban tree management and improves the accuracy of digital twin models. • Methodology for implementing urban tree growth in GIS-based solar radiation studies. • 20 years of tree growth reduce solar radiation on the ground by 6.1%. • 20 years of tree growth reduce solar radiation on the building roofs by 1.0%. • Tree growth increases evaporative cooling more than reducing PV energy. • Cities can update their urban tree database without new measurements.
Dynamic factors in life cycle assessment: systematic review and categorization
Chujun Zong, Werner Lang
Building Simulation Conference Proceedings, 2025
Globally, the building sector accounts for about one third of global CO2 emissions. In this context, life cycle assessment (LCA) serves as a strong instrument to quantify the environmental impacts throughout the complete life cycle of a building. Nevertheless, current LCA methods can be further refined from certain perspectives. For instance, the static calculation in the current LCA methods does not take temporal variations into account. Unlike analyses of life cycle cost and operational energy consumption, the dynamic changes of LCA results are rarely considered, which makes equivalent comparisons difficult. To deal with this problem, many studies were carried out in the last decade to discuss the dynamic LCA (DLCA) methodologies. Current studies on DLCA can be broadly divided into two main groups: dynamic life cycle inventory (DLCI) and dynamic life cycle impact assessment (DLCIA). However, this division is not sufficiently intuitive for LCA practitioners, complicating the integration and proper categorization of other various dynamic factors in practice. This leads to the lack of wider understanding about the concept of DLCA, especially within the building industry, which indirectly slows down the practical implementation of DLCA approaches in the building industry.In this research, we conduct a comprehensive review of dynamic factors that can potentially impact LCA results in the building industry and categorize the investigated dynamic factors into two types: background and foreground. This categorization directly addresses the difference of background and foreground databases. In addition, we introduce methods for modeling these dynamic factors. To demonstrate their practical applicability, we applied the categorized dynamic factors to one background database, ecoinvent, and one local foreground database, Ökobaudat. The results show that our new categorization of dynamic factors simplifies the modeling of dynamic factors and serves as a foundation for the further expansion of dynamic factors and for further development in DLCA methodologies.
Material Scouting for Urban Mining in the German Building Sector
I Takser, K Theilig, W Lang
Iop Conference Series Earth and Environmental Science, 2025
The transition from a linear to a circular economy in the building sector is essential to protect resources and reduce environmental impacts. A central strategy of circular construction is reusing existing materials, so-called Urban Mining. However, there is a lack of tools for a systematic search for materials for Urban Mining. This paper shows methods for material scouting for Urban Mining in the German building sector. The focus is on searching for buildings about to be demolished so their materials can potentially be reused. The following methods for searching demolition projects could be identified: (1) Internet research, (2) inquiries to institutions and players in the construction industry, (3) city inspection, and (4) public appeal. As part of a case study, methods 1-3 were used to find demolished buildings within a radius of 50 kilometers around a defined point. A total of 15 potential demolitions have been identified. After further research, the demolition plans for eight buildings could be confirmed through contacting the property owners. Permission for an initial inspection has been granted for two of the properties. The inspection of one property showed contamination with asbestos; further use of the structural components was ruled out. Through a student seminar, the urban mining components of the second property were documented. The analysis of the material scouting methods and the case study’s implementation showed that procuring reused building components is a time-consuming process characterized by uncertainties. This highlights the need to document used materials and building components in ongoing and future projects. Further, sourcing materials and building components must be simplified to scale construction with reused building components.
