Introduction Buildings and construction remain a major driver of global environmental change, accounting for approximately 34% of global CO₂ emissions and 32% of global energy consumption. At the same time, climate change, urban heat, and increasing environmental stressors are intensifying the need for robust, transparent, and scalable approaches to urban and building performance assessment. Advances in digital technologies, open-source computational tools, urban datasets, and interoperable workflows are transforming how researchers and practitioners investigate urban environments, evaluate mitigation strategies, and support evidence-based decision-making. As urban environmental modelling becomes increasingly data- and computation-intensive, reproducibility, interoperability, transparency, and reusable workflows are emerging as critical scientific challenges. While significant advances have been made in simulation platforms, digital twins, AI-assisted analytics, and urban-scale environmental modelling, methodological fragmentation, limited reproducibility, inconsistent data practices, and software interoperability barriers continue to hinder knowledge transfer and large-scale implementation across different climatic and urban contexts. This issue, “ Open and Reproducible Approaches for Urban Climate and Building Performance Modelling ”, aims to advance open and transferable urban environmental modelling ecosystems capable of supporting climate-responsive research and practice across different climatic and urban contexts. The issue welcomes innovative contributions addressing open, reproducible, and data-driven approaches for urban climate, building science, resilience, and sustainability research. Topics of interest include urban climate modelling and monitoring, outdoor thermal comfort, urban heat mitigation, building energy and environmental simulation, zero-carbon building and district decarbonisation modelling, materials and technologies, digital twins, GIS-based analysis, AI-assisted environmental assessment, uncertainty quantification, validation methodologies, open datasets, and decision-support systems for climate-responsive urban development. Particular emphasis is placed on methodological studies, benchmarking and validation research, interoperable workflows, software-oriented contributions, benchmark datasets, and reproducibility studies supporting transparent and reusable scientific practices. Contributions discussing uncertainty, limitations, and interoperability challenges are also encouraged. Collectively, these contributions will help advance more transparent, interoperable, and transferable urban environmental modelling practices. The Issue Themes This Issue aims to cover topics including, but not limited to, the following topics: Urban climate modelling, monitoring, and multi-scale analysis Urban heat island dynamics and mitigation strategies Outdoor thermal comfort and human-centric urban microclimate studies Building energy performance, zero carbon pathways, and district-scale decarbonisation modelling Cool materials, passive design, and urban heat mitigation technologies Digital twins, urban data platforms, and integrated simulation environments Open-source tools, interoperable workflows, and reproducible research practices Data-driven methods, AI, and machine learning for urban and building systems Validation, benchmarking, and uncertainty quantification in models and simulations Open datasets, measurement campaigns, and evidence-based decision-support systems Academic Editors Gloria Pignatta (g.pignatta@unsw.edu.au) Title: Scientia Senior Lecturer Affiliation: School of Built Environment, University of New South Wales (UNSW Sydney), Australia Official website: https://www.unsw.edu.au/staff/gloria-pignatta Gloria Pignatta is a Scientia Senior Lecturer in the School of Built Environment at the University of New South Wales (UNSW Sydney), Australia, and leads the Advanced Modelling and Building Performance (AMBP) Research Laboratory.

Introduction Buildings are increasingly required to deliver low-carbon performance while maintaining thermal, visual, and indoor environmental quality under more variable and extreme climatic conditions. This Research Topic focuses on integrated approaches that connect building envelopes, energy systems, passive and active strategies, and reliable performance simulation. Rather than treating the envelope and mechanical systems as isolated components, the topic invites studies that examine how façade design, envelope assemblies, shading, ventilation, heating and cooling systems, renewables, and controls interact across design, retrofit, and operation. The Research Topic, “ Integrated Building Envelopes and Energy Systems for Climate-Responsive, Low-Carbon Buildings ”, is intended to bridge architectural engineering, building physics, sustainable construction technologies, and data-informed performance assessment. It welcomes contributions on climate-responsive envelope design, envelope-HVAC-renewable integration, building energy systems, indoor environmental quality, low-carbon retrofit, and simulation-supported decision-making. Particular attention will be given to studies that combine physical understanding with measured data, calibrated simulation, uncertainty analysis, life-cycle thinking, and future climate scenarios. The Research Topic welcomes Original Research Articles, Review Articles, Case Studies, Methodological Papers, Perspectives, and Short Communications with strong methodological or empirical contributions. Collectively, the Research Topic aims to advance robust, climate-responsive, and low-carbon building solutions that are technically credible, environmentally meaningful, and transferable across different building types and climatic contexts. The Topic Themes This Research Topic welcomes submissions on, but is not limited to, the following areas: Climate-responsive building envelope design and adaptive façade technologies Envelope-HVAC-renewable energy system integration for low-carbon buildings Passive, active, and hybrid strategies for thermal regulation and energy reduction Low-carbon, circular, bio-based, and high-performance envelope materials and systems Building physics, dynamic thermal behaviour, indoor environmental quality, and occupant comfort Solar-responsive design, shading systems, daylighting, and thermo-visual performance Deep energy retrofit, nearly zero-energy buildings, and climate-neutral building stocks Building performance simulation, model calibration, validation, and uncertainty quantification Measured-data quality control, real-time simulation, digital twins, and data-informed operation Future weather scenarios, overheating risk, climate resilience, and performance robustness Academic Editors Dr. Haoxiang Zhan (haoxiang.zhan@sz.tsinghua.edu.cn) Affiliation: Institute of Future Human Habitats, Tsinghua University, Shenzhen, China Official website: https://orcid.org/0000-0003-1992-4126 Dr. Haoxiang Zhan is a Researcher at the Institute of Future Human Habitats, Tsinghua University, Shenzhen, China.
