EPB evaluation based on primary energy renewable & PER factor
No full textThe EPB assessment is one of the most important official systems adopted for building energy performance in Flanders, but at the same time focuses on primary energy (non-renewable) to cover the building's energy consumption. With the development of renewable energy generation systems, We must take into account the development of a new mechanism to assess the performance of buildings that derive their energy from renewable sources of energy, thus evaluate the building on this basis by creating an additional feature in EPB allowing this by development of factors that contribute to the development of the assessment method.
This report talks about the possibility of EPB calculation methods, the use of the PER factor in the PHPP calculation, and the possibility of developing a new EPB factor that enables us to evaluate the performance of the building based on renewable energy sources

Design criteria for circular buildings
Get PDFpeer reviewedThe term 'circular building' has mainly become popular over the last years and is now widespread across architectural and building engineering – at least in Europe. With climate change high up on the political and corporate agenda and introduction of the European Unions' Green Deal, the identification of design criteria for 'circular building' is in demand. Numerous approaches and projects have been proposed to develop evaluation criteria, ranging from sustainability rating systems (e.g., BREEAM and LEED), life cycle analysis methods, the Cradle to Cradle approach, Circular Building Service Companies (e.g., Oaplis and Werflink), research projects (e.g., BAMB, Facades leasing, FCRBE) and the European Waste Framework Directive and Circular Economy Action Plan. Despite the proliferation of those knowledge resources, however, there is an apparent lack of technical criteria to what extent a 'circular building design' is characterized. The scientific literature is surprisingly scarce of clarifications, even though countless studies on reversible building design exist. This paper explores the apparent discrepancy between professional and scientific use of the term 'circular building'. It suggests scientific design criteria based on commonly accepted circularity principles and environmental assessment modeling approaches. The paper answer a fundamental research question on the design criteria of a 'circular building' with an overarching aim to define robust indicators for their design and characterization
Development of the BCEF and DeCon Tools
Get PDFThis expert consultation report documents the development and validation of two interconnected tools aimed at enhancing circularity assessment in the building sector: the Building Circularity Evaluation Framework (BCEF) and the Expert System for Disassembly (DeCon). The report consolidates insights from multiple stakeholder workshops and structured expert interviews conducted between October 2024 and February 2025 with key partners including the Colruyt Group and the Sustainable Building Design Lab at the University of Liège. The consultations aimed to ensure the methodological robustness, operational feasibility, and industry relevance of both tools. Specific attention was given to selecting meaningful indicators for circularity assessment, validating disassembly criteria, and evaluating integration strategies with existing life cycle assessment (LCA) and building information modeling (BIM) workflows. Findings from these sessions contributed directly to refining indicator sets, prioritizing automation, and enhancing user experience in real-world contexts. The outcomes provide a practical foundation for architects, engineers, and sustainability practitioners committed to advancing circular building design and end-of-life adaptability.11.

Disassembly calculation criteria and methods for circular construction
Get PDFpeer reviewedCircular economy opportunities occur at every building life cycle stage. The consistent evaluation of the disassembly potential of buildings at different scales supports the decision-making for the sustainability of construction works. The main limitation in this field is the fragmentation and dispersion of criteria and methods for circular construction. The paper provides an overview of disassembly evaluation methods using a hybrid systematic review. The review is structured into two sections. The first section investigates generic studies assessing the disassembly potential of buildings, while the second section focuses on studies that address quantitative criteria and methods of disassembly evaluation of buildings. The study discusses the state-of-the-art metrics and
criteria that can be used in future European standards for circular construction. Also, the review helps researchers and building professionals to identify the most appropriate methods to evaluate buildings based on the principle of design for disassembly.11. Sustainable cities and communitie
Assessment of the circularity and carbon neutrality of an office building: The case of ’t Centrum in Westerlo, Belgium
Get PDFpeer reviewedCircular building design is a concept that is gaining great interest from architects, construction professionals, and their clients but is still rarely adopted in practice. One of the earliest design decisions architects and developers should make to design a circular building is to determine the building’s construction system. The choice of constructive and structural systems, such as columns, beams, and slabs, is crucial to upgrade the reuse cycles in the future. Flexible construction systems can make it easier to dismantle the structures and recover, upgrade, modify, or transform building materials. Therefore, this paper assesses the carbon emission impacts of two construction systems for an office building in Belgium using life cycle assessment (LCA) and circularity criteria. One-Click LCA software was used for the calculations. Parametric analysis took place for two construction systems scenarios involving a steel structure and a timber structure. Life Cycle Assessment and comparisons of the various construction systems are made based on ISO 14040, 14044, and CEN/TC 350 standards with a focus on carbon neutrality. The results show that using local plant-based materials such as wood can drastically reduce office buildings’ carbon footprint. Based on the sensitivity analysis results, the overall global warming potential impact is mostly sensitive to the construction material’s weight and reuse and dismantling ability. This paper provides a better understanding of building structural systems; to inform architects about the circularity potential of different construction systems
