[Article] Establishing industry-based benchmarks for embodied carbon in 85 buildings in China

Measuring embodied carbon is not enough. We need to know when a building is using too much of it. For years, the building sector has become increasingly sophisticated at calculating embodied carbon. But a calculation alone does not tell an architect, engineer, developer, or policymaker whether 250, 300, or 400

📘 Publication - CFD Assessment of Car Park Ventilation System in Case of Fire Event

Our research in Applied Sciences (2023, 13, 10190) shows that car park fires can be controlled without smoke blocking escape routes when ventilation design is driven by CFD evidence rather than intuition.

🏗️ How circular is a circular building—5 %, 10 %, or more?

That was one of the key questions discussed during my lecture “Decision Support for Circularity in Office Building Design” at the First LTH Circular Building Sector Seminar at Lund University (LTH), hosted by Pieter de Wilde. Grateful to have had an in-depth exchange with Kavan Javanroodi and Marie-Claude

🎬 [Video] Scientific Publishing - The Complete Guide for Researchers

Most researchers learn how to do science, but not how to publish it effectively. That’s why I created a comprehensive Scientific Publishing Playlist: 15 videos that guide you from idea to publication, helping you strategically build your academic impact. This opening episode sets the stage. It explains why publishing

[New Proceedings] Towards the Framework of Livable and Resilient Cities (Springer)

If you think urban resilience is a nice-to-have, the numbers below will change your mind. This collection distills 32 peer-reviewed papers from CCES-4 & HERL-3 into 4 action tracks—design, clean energy, climate adaptation, and behavior/policy—spanning case studies from 18+ countries (AU, CN,

[Seminar] 35th IEA Energy Storage Seminar, Task 43: Standardized Use of Building Mass as Storage for Renewables and Grid Flexibility

After three years of joint research, #Task43 is reaching its conclusion, demonstrating how thermally activated building systems (TABs) can make buildings active players in the energy transition. As Europe transitions toward 15-minute electricity markets, buildings themselves can become part of the flexibility solution. Rather than adding more batteries, we

Just Released: Net Zero Energy Buildings (NZEB): Concepts, Frameworks, and Roadmap for Project Analysis and Implementation – 2nd Edition

I am very pleased to announce the publication of the second edition of my book with Elsevier (Butterworth-Heinemann, September 2025). This updated volume builds on the foundation of the first edition, taking a significant step forward in addressing the carbon challenges of today’s built environment. Over the last
