Evaluating cognitive accessibility

Taking a cognitive perspective to architectural design is something architect Berta Brusilovsky Filer is passionate about. So she has written a book about it, Evaluating Cognitive Accessibility. Her free book is open access with the help of La Ciudad Accesible with the hope of reaching more people.

Cognitive accessibility is a fundamental aspect in the design of public spaces in the urban environment. At last this topic is receiving more attention in schools of design. The concept takes in easy reading, spatial orientation, signage and processes of interaction.

We rely on our brains to process information to make sense of the environment around us, but we don’t all process information in the same way. Consequently, if we design in a way that assists attention, perception, memory and problem solving, everyone benefits. Reducing cognitive load (too much going on) and maximising comprehension are key principles for independent movement around urban environments.

The book draws on the disciplines of architecture, social science and neuroscience, and presents an evaluation methodology for designers. However, it also provides a recent history of neuroscience and the role our brains play (or not) in making sense of things.

Lots of examples and photographs enhance this PDF publication. The chapter on recommendations covers the many elements of spatial orientation. The concluding chapter addresses the importance of involving people with cognitive conditions in the design process.

The full title of the free book is Evaluating Cognitive Accessibility: Scientific keys to strengthen the role of the evaluator with functional diversity.

Aged care design guidelines

Designing aged care facilities is a specialised endeavour but it can include some universal design thinking, such as co-design processes. Some aspects of these specialised designs have application in the design of mainstream homes and neighbourhood places and spaces. The new National Aged Care Design Principles and Guidelines are worth looking at for that reason.

Design Principles:

  • Enable the person
  • Cultivate a home
  • Access the outdoors
  • Connect with community

Plus, co-design processes involving all stakeholders.

The Aged Care Design Principles and Guidelines is a comprehensive, evidence-based resource designed for anyone with a stake in residential aged care. This includes accommodation providers and design professionals, staff, regulators and policymakers, and older Australians and their families.

The four design principles underpin the guidance which includes residents with dementia. Around half of aged care residents have dementia and half have reduced mobility. As expected, the designs benefit others with age-related health and care needs. Staff needs are also included. The key point is the importance of ‘home’ to residents – a place that reflects people’s needs and aspirations.

Six Personas

Personas cannot take the place of real people, but they are useful for explaining design ideas. That’s because they often provide the ‘why’ of a design. The guidelines use three resident personas, and three staff personas.

Each design principle has an objective and details on how to achieve it. For example, the objective for ‘Enable the Person’ is to support people to maintain health, wellbeing and sense of identity. Scenarios for residents and reasons why some things are important lead to checklists and a narrative for positive outcomes.

Mainstream applications

Considerations such as noise and clutter are just as relevant for people with dementia living in their own homes. Acoustic comfort is especially important for people with hearing loss, and everyone benefits from clean air and good lighting. Tonal or colour contrast becomes more important as people age rather than the fashionable all-white colour schemes.

The guidelines for bathrooms, ensuites and kitchens also have elements that help people in their own homes as well as home care staff. The main point is make them safe without looking like a hospital.

The title of the guideline is, National Aged Care Design Principles and Guidelines. The guidelines include design checklists and links to supporting evidence. Photographs enhance the publication.

Think about the windows

Guy Luscombe cover pic

Architect Guy Luscombe recently returned from a study trip in Europe focusing on living arrangements for older people.  His comprehensive report featuring case studies from Portugal, Spain, Switzerland, Germany, Denmark and Netherlands, reveals eight key design features important to older people. Windows was top of the list.

He says, “The traditional ‘nursing home’ and ‘retirement village’ are not only outdated, they can actually foster separation and ‘otherness’, isolating people from their family, friends and interests. The aim of this project is to explore how architects can design better environments for older people that improve their enjoyment of life. It starts with rethinking some of our design language.” Many in the universal design movement would agree with this.

Luscombe found 8 key design features with windows as the first priority for both light and seeing out into the neighbourhood. He makes some good comments. For example,

“Aged-care buildings are necessarily beset with constraints and regulations, some good, some outdated. However, many of the regulations put in place to ‘protect’ older people are very often seen as key design features of the building. They become the ‘end’ product. Buildings are seen as either compliant or non-compliant, rather than, say, promoting wellbeing and liveability.”

Spaces for all ages: three guides

Population ageing is a global phenomenon and the policy response is to focus on aged care and congregate living. The majority of older adults live in ordinary neighbourhoods, in ordinary homes. This policy blind spot means that anything to do with ageing is seen as a health or care responsibility and not an urban planning one. We need places and spaces for all ages and that means planning policy has to catch up with demographics.

It’s likely that ageist stereotypes underpins the policy blind spot. The World Health Organization’s Age-Friendly Communities Framework covers all aspects of life. Assumptions based on ageist stereotypes might also be why education is not on the WHO’s list.

The 8 domains of the WHO Age Friendly Cities Framework. They are presented in a circles and listed as: transportation, housing, social participation, respect and social inclusion, civic participation and employment, communication and information, community support and health services, outdoor spaces and buildings.

An article in Rethinking the Future briefly covers the issue of population ageing from a global perspective. High income countries are reaching the peak of their population ageing where up to 30 percent of the population is over 60 years old.

Making cities age-friendly is everybody’s business. It is the business of policy, planning, housing, transport, social services, corporations, small business, etc. The article introduces three guides for age-inclusive cities and public spaces.

The Alternative Age-friendly Handbook for the Socially Engaged Urban Practitioner discusses actions such as mapping, auditing, fixing and collaborating.

Age-Inclusive Public Space is a book that documents interaction with 19 practitioners – architects, geographers, psychologists, and social scientists. Each has a view of designing, using and transforming public space to be more inclusive.

Shaping Ageing Cities focuses on 10 European cities facing ageing populations. This report looks at the built environment, housing, mobility and digital environments.

The article concludes by saying cities will have to adapt to changing needs with inclusivity – age-inclusive design practices. There is a short reference list at the end.

Design for the autistic community

The Autumn 2023 Access Insight magazine has an article by John Van der Have on designing for autism. He introduces a design guide by Magda Mostafa and her work on design for the autistic community.

Van der Have begins his article with an older medical description of autism (ASD) and some statistics. As many people know, sensory overload is common for people within the neurodivergent community. Too many sights, sounds, smells and tactile experiences can cause stress and anxiety. That’s why the choice of building materials and systems need additional consideration.

Minimising noise and unwanted sounds through good acoustic design is a vital criterion. But how much acoustic insulation is enough, and how much is too much? Questions such as these have implications for construction costs.

A man is placing headphones over his ears. He is facing away from the camera. The background is blurred from traffic or public transport.

Biophilic principles are beneficial for everyone, but for the autistic community, these elements can enhance their sense of wellbeing. Natural lighting, natural ventilation and views of nature are especially helpful.

Van der Have discusses educational settings and a time-out room where children can still learn in a supportive environment. A calming space at home, as well as a room fitted out to suit a child’s preferences is also a good idea.

As we begin to understand autism and neurodiversity, it’s possible there will be moves to regulate suitable designs. However, regulation should not be needed if designers take action themselves to be more inclusive. Van der Have’s article is on page 18 of Access Insight. It is titled, Design for People on the Autism Spectrum and introduces the work of Magda Mostafa.

Autism friendly design guide

Magda Mostafa, an architect and researcher, developed a design framework for incorporating the needs of the neurodivergent community. The framework is based on 7 design concepts:

  • Acustics
  • Spatial Sequencing
  • Escape
  • Compartmentalisation
  • Transition
  • Sensory Zoning
  • Safety

In Cities People Love, Mostafa talks about her experiences as an architect working as an autism design consultant. She says designers have to rethink the tools they need. A human-centred approach to design, such as focus groups, assumes everyone is able to speak and participate. She wants to see the principles from the Autism Friendly University Design Guide applied more widely.

The Autism Friendly University Design Guide was developed in collaboration with the Dublin City University and is applicable in other settings. The first half of the 116 page detailed guide covers the research, and the second has the guiding principles. Mostafa’s work is worth following for anyone interested in designing for neurodivergence.

This edition of Access Insight also has an article on water safety for autistic children on page 4.

Aged care design principles

While the principles of universal design aim to enable people to stay in their own home for as long as they wish, the principles are also applicable to aged care settings. Four principles underpin the Australian Government’s National Aged Care Design Principles and Guidelines. These principles are:

  • Enable the person
  • Cultivate a home
  • Access the outdoors
  • Connect with community

The four principles are, of course, applicable to any dwelling or place of accommodation. This is an example of universal design where specific features are essential for some and good for everyone. Consequently, the document is useful for anyone designing any type of home.

Front cover in bright yellow of the National Aged Care Design Principles and Guidelines.

The guideline provides detail on each principle. For example, the first principle covers acoustics, air quality, lighting, tonal contrast, supportive seating and comfortable temperatures. Before and after illustrations as shown below provide additional information. At the end of each sub-section is a checklist.

The authors have chosen to use six personas to bridge the gap between abstract concepts and lived experience of residents and staff. Three personas for each group is possibly too few and runs the risk of limiting a designer’s vision of the breadth of diversity. For example, cultural diversity is considered, but other characteristics such as marital status and sexual orientation are not.

The outcomes for the resident personas are explained alongside each checklist. They provide some of the “why” certain features are required by individuals.

Overall, this is a useful guide for aged care in any context – indeed for all people. After all, home is the centre point of our lives. Below is a page from the guidelines showing before and after illustrations.

Social Value Toolkit for architecture

Design impacts both social and economic value to a community, but how do you measure and track it? The RIBA Social Value Toolkit has the answer. The Toolkit makes it easy to evaluate and demonstrate the impact of design on people and communities. A research project by the University of Reading provided the evidence for the Toolkit.

“If we cannot define what we mean by value, we cannot be sure to produce it, nor to share it fairly, nor to sustain economic growth.” (Mazzucato, 2018)

“Social value is created when buildings, places, and infrastructure support environmental, economic and social wellbeing to improve people’s quality of life.” (UK Green Building Council)

Front cover of the Social Value Toolkit. Deep blue with light blue text.

The underpinning concepts for the Toolkit are based in the wellbeing literature. Social value of architecture is in fostering positive emotions, connecting people, and in supporting participation. The Toolkit has two parts. A library of post occupancy evaluation questions, and a monetisation tool that links to other post occupancy evaluation processes.

Eilish Barry says that if we don’t define and measure the social impact of design, it will be pushed further down the priority list as costs rise. Generating social value is useful for potential future residents as well as designers and developers. Barry poses five recommendations for industry in her Fifth Estate article:

  • Knowledege sharing is vital
  • We need a common language
  • Social value should be part of the design process
  • Methodologies need to be flexible
  • Opportunity for collaboration (Eilish Barry pictured)

The Social Value Toolkit

The library of questions means you don’t have to reinvent the wheel. They cover positive emotions, connecting, freedom and flexibility, and participation. Each of these has a monetary value attached.

The dimensions of social value in the built environment context.

The approach to monetising social outcomes is based on Social Return on Investment. There are several different ways to measure this.

  1. Value for money: Willingness to pay extra for something you value.
  2. Time is money: The value of savingtime.
  3. Subjective Wellbeing valuation: Putting a value on wellbeing – most appropriate to understanding the impact of design on end users.

The Toolkit references the UK Social Value Bank, an open access source that contains a series of values based on subjective wellbeing valuation. There is also an Australian Social Value Bank with resources.

The Toolkit is briefly explained on the Royal Institute of British Architects website where you can download the 2MB document. Or you can access the document here.

Dementia friendly outdoors

We know that people want to stay home as they age. This does not change for people with dementia. Staying safe at home also means staying safe in the neighbourhood, not just at home. That means we need a dementia-friendly outdoors.

Ash Osborne writes in the Access Insight magazine about dementia and outdoor environments. Although dementia is NOT a normal part of ageing, one in ten people over the age of 65 experience dementia. It is the single greatest cause of disability for this group. 

A black and white paved area. The black pavers are laid in an "S" shape and look like a long black snake against the white pavers. Not very dementia friendly outoors.

Osborne takes us through the key design elements that support people with dementia as well as other groups. Depth perception often changes and that means strong changes in contrast can be perceived as steps or a hole. This can lead to falls.

Sun cast shadows through a pergola with large beams create shadows on the footpath that look like steps.

Wiggly lines in paving and sun-cast shadows from a pergola are similar situations. A black mat at a doorway looks like a hole in the ground and pooled lighting can be confusing. So the images show what NOT to do.

Distortions of perception are not just experienced by some people with dementia. So, once again, think universal design.

Osborne’s article, Age and Dementia Friendly Outdoor Spaces is an informative introduction to the topic. 

Dementia and urban design

In Improving the lives of people with dementia through urban design, Barbara Pani presents four brief case studies: a gated community, a dementia-friendly city, intergenerational housing, and health services at a neighbourhood level in a social housing estate.

The article provides technical information and in the conclusion raises several points. Retrofitting existing buildings could be better than a massive redevelopment.

Consideration of people with dementia could also be good for the wellbeing of people with mental health issues, and the importance of developing social spaces at the neighbourhood level. 

Many people with dementia are able to live independently for several years before they need constant care and support. Studies are showing that the design of the built environment is influential in supporting people with dementia to maintain their sense of well-being and independence.

Out and about with dementia

Getting out and about is good for everyone’s physical and mental health. However, the fear of getting lost or confused when outside the home prevents many people with dementia from leaving home. Consequently, they tend to limit their time away from the house. But with good planning and community help, people with dementia can maintain the benefits of walking and taking a holiday.

“I am a person.

Sometimes people like to go for walks, even people with dementia. Sometimes people get lost, even people without dementia”

Taken from Kate Swaffer’s poem, ‘Wandering along the beach’. (2014)

Front cover of Walking with Dementia.

Dementia Australia has two booklets, Walking safely with dementia, and Travelling and holidays with dementia. These booklets are designed for people with dementia and their families. However, the information is good for communities who want to make their places and spaces dementia friendly.

Walking

The walking guide features strategies people can take to make sure they stay safe and know what to do if they become lost. They can be as simple as carrying identification and establishing familiar routines and places. The section on safety involves avoiding crowds and disorienting entry and exits. Double entry and exits in shopping centres can cause confusion for people without dementia. Directional signage on the way out of the toilet is useful for everyone.

Dementia Australia has a Dementia-Friendly Communities program where people can learn more about dementia and how they can help. There’s a list of things you can do if you meet someone who may be lost.

“My mother has dementia, but her life continues to be enriched with fulfilment. We went on a cruise last year that provided us with uninterrupted time, gave me some time to relax and just be there for my mum while our needs were taken care of. It was difficult at times, but so rewarding to have shared this time together”

Front cover of Travelling and holidays with dementia.

Travelling and holidays

Similarly to the walking guide, careful planning is key to success. The holiday booklet covers travel by sea, air, car and public transport. There’s a checklist of things to consider and how you can plan to optimise your level of capability. When it comes to accommodation, it’s useful to notify hotel staff. Some hotel accessible rooms might be more comfortable.

There is nothing in this booklet for transportation agencies for people with dementia. However, it gives travel and accommodation providers insights into the lives of people with dementia and their families.

Inclusive building design: a guide

Talking about inclusive built environments is easy, but how do you do it well? With different stakeholders involved in the design and delivery of a project, how do you get them to join up their thinking to approach projects with the same inclusive mindset? An inclusive building design guide focused on the processes is the way to do it.

The Royal Institute of British Architects (RIBA) created an Inclusion Charter in 2020. One of their commitments was to embed inclusive design in all projects. But architects cannot work in isolation – all stakeholders need to take on an inclusive mindset. As an extension to their Charter, they created the Inclusive Design Overlay to the RIBA Plan of Work. It seeks to bring all stakeholders on board for every part of the project.

“The role our built environment has on each and every person’s life cannot be overestimated. This Inclusive Design Overlay provides a consensus across built environment professions for how we accelerate inclusion and value diversity.” Robbie Turner, Director of Inclusion and Diversity, RIBA.

Front cover of the RIBA Inclusive Design Overlay showing a montage of nine different groups of people.

Twenty-five different built environment professions provided insights and best practice content for the overlay. The inclusive design tasks apply to the client, project management team, design team, construction team and asset management team.

There are three core parts: the Client Team, the Design Team and the Construction Team. In addition, they recommend having an inclusive design consultant, or champion, with specialist inclusive design expertise. As Australian access consultants know, the earlier they are consulted the better. So it is good to see RIBA encouraging involvement from the outset of the project. The overlay also encourages the project team to look beyond building regulations.

Good design must be fundamentally inclusive just as it should be sustainable and resilient. Inclusive design should be elevated to the same level as sustainability.

The overlay details the roles of each team and stages of work. It begins with setting the project brief and budget through concept design, construction and handover to asset managers. There are separate sections for each of the key teams and what they should do and understand at each stage.

Enablers

The document includes a section on inclusive design enablers. These are actions that support the development of an inclusive design strategy, and implementation of inclusive design across the delivery of a project. Each sub-section has clear information on the diversity of the population and different levels of capability, and how to approach them in design and construction processes.

Access the document by visiting the landing page on the RIBA website, which will give you an overview as well.

Editor’s note: In the UK they use the term “inclusive design” where other countries use “universal design”. The goals and actions are the same.

Design guide for active travel

This design guide aims to improve infrastructure for people wanting to walk, cycle, scoot, and ride mobility devices. That means anyone and everyone who is not a driver of a motor vehicle. This is part of the ACT Government’s policy is to support active travel.

In the Canberra context, unless designated, all paths are shared by people walking, wheeling, cycling and using mobility aids.

Few people fully understand road rules, which is why design treatments must indicate that pedestrians have priority.

A diagram of an intersection taking from the Design Guide .

People using mobility devices and older people are given the label of “vulnerable” pedestrians. This is default language in transport jargon, but serves, unfortunately, to reinforce stereotypes. In reality, all pedestrians are vulnerable compared to motor vehicles.

When all pedestrians are incorporated into designs, we should just talk about “pedestrians walking and wheeling”. And with a Safe Systems Approach there should be no delineation between who is safer than whom.

Movement and Place framework

The Movement and Place framework together with a Safe Systems approach puts people into the centre of the frame. The lens has always been on vehicle traffic flows and the convenience and economics of reducing traffic delays. If we are to have active travel really happening, we have to re-think this priority.

The Design Guide is comprehensive and serves as a “how-to” tool for transport planners. It covers:

  • principles of safe design
  • street types
  • walking
  • cycling and micromobility
  • intersection principles and elements
  • signalisation
  • pedestrian and cycling provision at intersections
  • public transport
  • intersection guidance

Access Audit Handbook

The Royal Institute of British Architects has updated their Access Audit Handbook in conjunction with the Centre for Accessible Environments. Access auditing is an evolving concept and means different things to different people. Some take it as being compliant with a standard while others consider aspects beyond compliance.

The Access Audit Handbook is priced at £40.00 from either the Centre for Accessible Environments or the Royal Institute of British Architects.

Fortunately, the Ergonomics in Design for All Newsletter explains the content of the document. In doing so, the newsletter provides an synopsis of some of the key concepts in the handbook.

Front cover of the access audit handbook.

Similarly to Australian Standards, British Standards only apply to people with disability and do not cover any other groups in terms of access and inclusion. This is despite other groups who fall under anti-discrimination law. The handbook addresses some of these gaps. For example:

Faith spaces, prayer facilities, features relating to women’s safety and their well-being, including pregnancy and menopause, baby feeding and changing, and non-gendered sanitary and changing facilities.

A woman cradles a new baby in her arms. They are both white skinned.

There is guidance on neurodiversity and reducing sensory overload, anxiety and stress, such as quiet rooms. Designers are asked to plan logical wayfinding with straight lines, and create curves rather than corners.

Technology is evolving on building accessibility, space and wayfinding, and auditors need to keep up with these developments. Lift destination control systems are a case in point where people no longer press a button for their floor. The central control system can be very confusing where there is a bank of lifts.

Case studies

The handbook recommends engaging with building users for insights into the level of accessibility and to keep them engaged throughout the project. There are six case studies: a theatre, a zoo, a parish church, a university science lab, and an outdoor space. The case study of an inaccessible heritage town hall shows how to create an accessible community building.

The handbook has 32 checklists for the external environment, internal building space, management and communication.
