Trusting Building Performance Simulation

As codes and regulations become stricter, is simulation the right tool for compliance as well as sketching performance to assist design?

This special issue examines whether building  performance simulations can be trusted for their accuracy and reliability. An increasing urgency exists to provide a prediction of performance over the next 50-100 years. As carbon limits become more fixed on absolute performance, a consensus is needed on how to examine performance reliably and accurately – both for new buildings as well as interventions in existing buildings. Several different concerns are addressed pertaining to the building performance gap - particularly practices and expectations.

Architectural Epidemiology: Architecture as a Mechanism for Designing a Healthier, More Sustainable and Resilient World

By Adele Houghton and Carlos Castillo-Salgado. John Hopkins University Press, 2025, ISBN: 9781421450698

Building-Related Research: New Context, New Challenges

Overview and reflections on key built environment research challenges raised in B&C's anniversary essays

Raymond J. Cole (University of British Columbia) reflects on the key challenges raised in the 34 commissioned essays for Buildings & Cities 5th anniversary. Not only are key research issues identified, but the consequences of changing contexts for conducting research and tailoring its influence on society are highlighted as key areas of action.

Lessons from Disaster Recovery: Build Better Before

Rethinking the building code means including performance objectives to limit damage and increase redundancy

Mary C. Comerio (University of California, Berkeley) explains why disaster recovery must begin well before a disaster occurs. The goal is to reduce the potential for damage beforehand by making housing delivery (e.g. capabilities and the physical, technical and institutional infrastructures) both more resilient and more capable of building back after disasters.

Will NDC 3.0 Drive a Buildings Breakthrough?

Why policymakers should create mitigation roadmaps for construction and real estate

To achieve net zero GHG emissions by mid-century (the Breakthrough Agenda) it is vital to establish explicit sector-specific roadmaps and targets. With an eye to the forthcoming COP30 in Brazil and based on work in the IEA EBC Annex 89, Thomas Lützkendorf, Greg Foliente and Alexander Passer argue why specific goals and measures for building, construction and real estate are needed in the forthcoming round of Nationally Determined Contributions (NDC 3.0).

Self-Organised Knowledge Space as a Living Lab

How can a self-organised initiative in an informal settlement foster community engagement and confront social issues?

While Living Labs are often framed as structured, institutionalised spaces for innovation, Sadia Sharmin (Habitat Forum Berlin) reinterprets the concept through the lens of grassroots urban practices. She argues that self-organised knowledge spaces can function as Living Labs by fostering situated learning, collective agency, and community resilience. The example of a Living Lab in Bangladesh provides a model pathway to civic participation and spatial justice.

Climate Mitigation & Carbon Budgets: Research Challenges

Why the built environment research community is vital for policy and strategy implementation

Thomas Lützkendorf (Karlsruhe Institute of Technology) explains how the research community has helped to change the climate change policy landscape for the construction and real estate sectors, particularly for mitigating GHG emissions. Evidence can be used to influence policy pathways and carbon budgets, and to develop detailed carbon strategies and implementation. A key challenge is to create a stronger connection between the requirements for individual buildings and the national reduction pathways for the built environment.

Co-ordinate Built Environment Research for the Public Good

Why a coordinated programme of built environment research needs to be based on the public good

Gavin Killip and Kate Simpson (Nottingham Trent University) propose a coordinated research programme of field trials to create a focus for iterative learning about outcomes in the built environment, for the public good. They explain why a transdisciplinary programme is needed and seven key characteristics of the programme are proposed.

B&C's Readership Metric

Research papers in B&C are being widely read

Buildings & Cities is pleased to announce that in 2024 our peer reviewed articles were viewed and downloaded 523,612 times from the journal's website.

The great interest shown here is an indicator of the journal's role as an important resource and as a valued contributor to the field.

Reframing Sustainable Construction

Why a new approach to sustainable development is needed.

Alice Moncaster (University of the West of England) reflects on the lack of progress in sustainable development over several decades. This failure is argued to be linked to how sustainable development has been framed: the separation of technical issues from social justice and equity. Understanding, involving and empowering communities (and wider society) is the key to making progress and achieving sustainable development goals.

Artificial Intelligence and Decarbonisation

How building research can harness AI for mass decarbonisation

Ten years ago, it was rare to read building science papers referencing learning algorithms, sensor networks, cloud computing or digital twins. Now, data-driven techniques are at the core of building decarbonisation research, generating both new opportunities and new risks. Jenn McArthur (Toronto Metropolitan University) reflects on how the rise of artificial intelligence (AI) is transforming building decarbonisation research.

Cities-Scale Research to Address Climate Change

Understanding the interactions between urban form, outdoor and indoor spaces, and local climate requIres interdisciplinary interaction

Gerald Mills (University College Dublin) considers the big challenges for cities amid global climate change (GCC) and discusses the need for an inter-disciplinary approach among urban climate sciences to overcome obstacles. A distinction is made between global climate science, which focusses on Earth-scale outcomes, and urban climate science, which refers to processes and impacts at city-scales, including buildings, streets and neighbourhoods.

Climate Change, Overshoot and the Demise of Large Cities

Why large cities will need to contract or be abandoned altogether

William E. Rees (University of British Columbia) explains why urbanisation has been a significant contributor to ecological overshoot (when human consumption and waste generation exceeds the regenerative capacity of supporting ecosystems) and climate change.¹ Civil society needs to begin designing a truly viable future involving a 'Plan B' for orderly local degrowth of large cities.

The Sixth Industrial Revolution Should be Ecological

Why the next industrial revolution needs to be based on nature and not "technology"

Over the past 50 years the world has seen countless summits and agreements to reduce carbon emissions and prevent ecological overshoot. We have seen widespread adoption of the SDGs, a rapid shift to renewable energy, and numerous urban planning strategies to create biodiversity corridors, rewild rivers, and enable public and non-motorised transport options. However, appearances are deceiving. Chrisna du Plessis (University of Pretoria) considers the challenge of how to foster an ecological civilization in a world obsessed with technological innovation.

Energy Sufficiency in Buildings and Cities

How can conditions be created for decent living standards for all without exceeding planetary limits?

Energy and climate policies have tended to focus on the promotion of energy efficiency and renewable energies, but there is no evidence that these measures alone will be able to meet climate and sustainable development goals. This special issue explores what the concept of sufficiency means for the built environment - both as a floor (minimum) and a ceiling (maximum) to ensure a "good life". Sufficiency is explored in many interconnected issues such as land use and density, space usage (size and adaptability), sharing of goods, services and spaces, and space conditioning (heating, cooling and ventilation) for health.
