Retrofitting Buildings to Support the Recovery

Why is building retrofit important for a sustainable economic recovery? What are key elements for success?

Faye Wade (University of Edinburgh) highlights the importance of building retrofit for a sustainable economic recovery from the COVID-19 pandemic. Not only does retrofitting promise a major step toward a low carbon society, it also contributes to increased GDP and jobs in the construction sector.

Is High Density Necessary for Future Urban Life?

Smaller cities and towns can offer attractive forms of urbanism and quality of life. Alternative criteria to density are needed.

Mari Vaattovaara (University of Helsinki) critiques the current emphasis on city density and size as desirable quality indicators.  If emphasis is placed on the quality of physical environment or quality of life, then smaller cities and towns are both viable and desirable alternatives. 

Reflections on Buildings, Cities and COVID-19

How will social distancing and new practices change real estate, facilities management and the use of buildings?

COVID-19 will change real estate practices and how we use buildings - during the cautious present re-opening of gathering places whilst the virus remains a threat; and possibly for the longer term.  Alexi Marmot (University College London) considers some implications for the built environment, particularly the operation of our workplaces, schools, healthcare environments, retail centres and cities. Will the role of facilities manager be re-defined and given more prominence?

Housing: Lessons for a Post-COVID-19 World

How can housing be healthy, adaptable, resilient and optimised for the multiple functions?

Dwellings provide not just a living space, but act as a pandemic shelter, a workplace, an impromptu school, a gym, a playground and more.  Katja Maununaho, Sini Saarimaa, Jyrki Tarpio and Sofie Pelsmakers (Tampere University) critique current apartment design and contemplate how apartments can be designed to be adaptable and respond better to many existing and new needs. 

Hackitt and the Golden Thread: Challenges to Implementation

Will the Hackitt Review recommendations be easily implemented?

Graham Spinardi (University of Edinburgh) explores the implications of the Hackitt Review into fire safety regulation following the Grenfell Tower disaster. In particular, he considers the challenges to implementing a digital 'golden thread' of building information throughout a building's life cycle.

Will Working from Home Become the New Normal?

During Covid-19 pandemic office buildings are no longer the places where people spend half their waking time.

Chiara Tagliaro explains how the workplace is changing due to the shift to working from home. Key questions and challenges are posed for researchers, practitioners and facility managers: to create a strong evidence base and define appropriate new practices for a range of circumstances and individuals.

After COVID-19: Opportunity for Changing Building Regulations?

Is the current situation an opportunity to undertake fundamental changes in the building regulatory process in order to ensure safe and healthy buildings?

David Eisenberg (Development Center for Appropriate Technology) and Rick Diamond (Lawrence Berkeley National Laboratory) consider the opportunities and challenges of building regulatory reform in the post-pandemic period.

Pandemics: Why Buildings are Hazards

Wastewater systems in tall buildings are a transmission pathway for pathogens. Despite robust evidence (and clear solutions), standards, codes and regulations have failed to respond and present a public health risk.

Michael Gormley (Heriot Watt University) explains a neglected area of public health and building design: the plumbing systems for wastewater.  What can building designers and regulators can do to reduce the hazard of disease transmission in tall buildings?

Design Professionals Challenging Disasters

Disasters are not natural occurrences. The design of cities and buildings can exacerbate or eliminate most disasters.

Ilan Kelman (University College London & University of Agder) explains why disasters are caused by humans - disasters come from a society's decisions and actions, not nature. Many disasters can be eliminated through design, regulation and social practices. Built environment professionals have a significant role in tackling disasters involving risk identification, assessment, and management. Vulnerability takes a long time to create or eliminate due to the slow evolution of most cities.

From SARS to COVID-19 and Beyond: Public Health Lessons for Buildings

The built environment has a fundamental role in maintaining public health. What lessons has Hong Kong applied to reduce the spread of contagion?

An important function of the built environment is providing a safe place for its inhabitants.  Edward Ng (Chinese University of Hong Kong) recalls the spread of SARS in Hong Kong and reflects on the public health lessons for the built environment. A process of preparation and management is vital for reducing present and future health risks. This is becoming evident in Hong Kong's recent codes and regulations for urban design and buildings . Other cities can learn from this process.

Scientific Conferences and the Pandemic

The present format of scientific conferences is outdated and needs to rapidly change. How we can reconfigure conferences to better suit the needs of researchers?

The COVID-19 outbreak has cancelled or postponed conferences, shifting others to virtual meetings.  This presents an opportunity to reflect on the questions about the purpose of scientific conferences and ways to improve them: how can they function more effectively, how are they organised, who are the major beneficiaries, should their number be reduced, and how to limit their environmental impacts (especially from air travel)?  Buildings & Cities' Richard Lorch argues for the urgent need to change scientific conferences.

Beyond Theory: Climate Justice in Practice

What role does the built environment have in addressing climate injustices?

This community-led initiative provides a practical approach to addressing climate injustices, specifically those experienced by Black and brown communities and low-income residents in Portland, Oregon. Rev. E.D. Mondainé and Mandy Lee present a pioneering approach that embraces both climate (mitigation and adaptation) and inequality issues to improve community resilience and wellbeing. A climate justice approach is better than attempting to solve one issue at a time.

Beyond the Declaration: Delivery of GHG Reductions

Architect Peter Clegg of Feilden Clegg Bradley Studios considers the 'Architects Declare' movement and what it means for designers to put these ideas into practice.

Architect Peter Clegg (Feilden Clegg Bradley Studios) describes the 'Architects Declare' movement, which was established in response to the climate emergency. He explores how the principles of 'Architects Declare' can be put into action, particularly through considering both operational energy and embodied carbon during the design of buildings.

Research Contributes to Achieving Global Environmental Goals

Robert Crawford (The University of Melbourne) explains the importance of research to create a radical, informed shift in the way we design and construct our buildings and cities.

Robert Crawford (The University of Melbourne) explains the importance of research for making a radical, informed shift in the way we design and construct our buildings and cities. A database on the embodied environmental aspects of construction materials shows how researchers, the construction industry and government can develop a much more environmentally responsive approach to our built environment.

Can Urban Scale Digital Twins Address Climate Adaptation?

Martin Mayfield (University of Sheffield) explains the importance of Urban Scale Digital Twins.

Urban infrastructure systems are essential supporting instruments of society; they evolve gradually and some 19^th century infrastructure remains viable and essential today. Martin Mayfield discusses how urban scale digital twins (USDT) provide a holistic approach to urban and infrastructure design, operation and future proofing.

Why Tools for Buildings and Cities Performance Simulation Need to Evolve

Joe Clarke (University of Strathclyde) describes the '7 deadly sins' associated with performance simulation tools.

Simulation tools offer increased opportunities for understanding building performance, but also present significant challenges. To overcome the '7 deadly sins' associated with performance simulation tools, Joe Clarke argues that structural changes are needed involving the roles of construction industry, professional bodies, researchers and software developers.

Overheating in New Homes: A New Design Tool

Kevin Lomas discusses a new tool for the identifying and reducing overheating risk

The risk of overheating in homes is an increasing problem in the UK and elsewhere. Kevin Lomas discusses a ground-breaking new tool developed and launched to assist designers, planners and clients to identify and reduce the risk of summer overheating in dwellings.

Modern Methods of Construction: Unintended Consequences

Stuart Green explores the promises and pitfalls of Modern Methods of Construction

This article considers whether Modern Methods of Construction (MMC) can really resolve the construction industry's challenges of a diminishing workforce and low productivity, whilst also delivering a more energy efficient built environment. Stuart Green explores how an alternative conceptualisation might help to avoid failure.

Architecture and the Climate Emergency

Alan Short responds to the Climate Emergency and argues we must rethink our dependency on the mechanical conditioning of buildings.

A city comprised of buildings with high energy demand is risky and damaging to the climate. Alan Short suggests that for change to occur, the behaviours and attitudes of the supply side need to change. The main barrier is for clients and their designers to break with the status quo.

Climate Emergency and Built Environment Education

Fionn Stevenson explains why rapid change is needed to redefine education and training. Students need to be able to access and understand existing principles, methods and solutions for carefully defined, problem and evidence-based learning.

The built environment disciplines and their corresponding institutes / regulators must radically update their professional validation criteria for their education programmes now and more closely define the key competences that professionals must have. Fionn Stevenson explains why rapid change is needed to redefine education and training.
