can be applied to virtual
environments as well.

2  Building Accessible and Inclusive Environments

 This handbook introduces the concept of
universal design, as well as the impacts that
standard and traditional design projects have
on people with disabilities and older adults.*
It outlines what access-for-everyone entails,
provides policy that supports universal design
and puts the future of universal design,
into perspective.

One objective of this handbook is to encourage

design professionals – be they designers,
architects, developers or planners – and the
public to participate in universal design. By
providing recommendations and examples
of design that can be implemented in public
and private spaces, this handbook seeks to
demonstrate the advantages of going beyond
minimum building code requirements and
providing equal access, social inclusion and a
level playing field for all.
*Throughout this handbook, the term “older adults” refers to persons
aged 65 or older, or those approaching this age range.
Universal design is the best practice for
designing new environments today because it
embodies two simple – yet critically relevant –
tenets: it’s sustainable and cost-effective.

Making a building accessible from the beginning

is easier and more cost-effective than retrofitting
an existing building. Universally designed
projects are built with everyone in mind and
can benefit the greatest number of people.
Regardless of ability, these environments can be
accessible, functional and aesthetically pleasing.

1 Backgrounder

1.1 Municipal committees

supporting Universal
design
In May 1999, Calgary City Council approved
the establishment of the Advisory Committee on
Accessibility (ACA) as part of the Transportation
Services for People with Disabilities Review.

The primary purpose of the ACA is to focus

on broad policy issues and advise Calgary
City Council on the accessibility of municipal
properties, information and services. ACA is
composed of appointed representatives from
the community and City administrative staff.
There are two subcommittees of the ACA:
Access Design and Accessible Transportation
(The City of Calgary, 2005).

1.1.1 Access Design Subcommittee

The Access Design Subcommittee reviews
and makes recommendations on plans
and/or issues relating to accessibility for people
with disabilities. This includes, but is not limited
to, the review of major public and private
projects (e.g., properties, buildings, walkways, 1.1.2 A

fellow, was an architect who used a wheelchair
and personally experienced the stigma
associated with a disability. He acknowledged
that time is needed to change attitudes, but
that a day would come when universal design
practices would be standardized. A few years
later, an academic institute incorporated
universal design as part of their curriculum.

2.3 Center for Universal Design

The Center for Universal Design was established
in 1989 at Raleigh’s North Carolina State
University. The Center is a national research,
information and technical assistance center that
evaluates, develops and promotes accessible
and universal design in housing, buildings,
outdoor and urban environments and related
products (Center for Universal Design, 2007).

The Center’s mission is to improve the built

environment and related products for all users
by impacting change in policies and procedures
through research, information, training and
design assistance. The Center developed
a successful program of assembling and
disseminating existing information and creates
new, landmark materials on accessible housing.

In order to achieve universality, collaboration is
paramount. Although design professionals have
a vested interest in promoting their profession,
a synergy must develop between academic
disciplines that look at trends, user needs,
etc. (e.g. social scientists, population health
researchers, market researchers, gerontologists
and others), in order to successfully pursue
universal design and avoid retrofit.

Challenge: lack of understanding.

Solution: education.
Armed with research about what consumers
really want from their products – and
with an openness to collaboration –
today’s design professionals are finding
themselves at the forefront of an exciting,
innovative and very lucrative market for
universally designed environments.

3.2 Disability: an
increasing reality
The World Health Organization (WHO) has
developed a broad definition for disability as
“any restriction or lack of an ability to perform
an activity in the manner, or within the range
considered usual, for a human being.”

Population projections for The City of Calgary

demonstrate that disability rates among
Calgarians are increasing significantly.
While it is commonly accepted that
individuals aged 65 years and older are
reporting the highest incidents of disability,
trends demonstrate that an emergent
population of adults between the ages of
45 and 64 are already reporting high rates.
In Calgary, this age group shows an estimated
increase of 27 per cent (see Figure 1).

3.5 Types of disability checklist
The following checklist provides an overview of the diverse types of disabilities – from those
acquired through genetic inheritance, accident, the process of aging or a combination of these – and
how each carries its unique attributes and accessibility requirements.

Readers will also find common terms that help demonstrate what it’s like to live with a disability and
lastly, this checklist includes various assistive devices/measures that people with disabilities use/need
to help them move through, participate with and communicate in the built environment.

Disability type Physical: agility/mobility ✓

Common terms Ambulatory: able or strong enough to walk.

Semi-ambulatory: able to walk short distances with small steps.

Non-ambulatory: unable to walk.

Fractures: the breaking of bones and cartilage (note: persons confined

to wheelchairs have more brittle bones and are more susceptible
to fractures).
Paraplegia: a break or lumbar injury causing total or partial paralysis of
the lower limbs, which may be spastic or flaccid.
Quadriplegia: total or partial paralysis of all four limbs and the torso.

Amputation: loss or removal of limb.

Prosthetic: an artificial extension that replaces a missing body part.

Spinal cord injury: causes damage to white matter, or myelinated fiber

tracts that carry signals to and from the brain. It also damages gray matter
in the central part of the spine causing segmental losses of interneurons
and motorneurons. Spinal cord injury can occur in many ways, including
accidents, tumours (cancer), developmental disorders (spina bifida),
inflammation (stroke) and vascular malformations (aneurysm).

 Disability type Physical: agility/mobility (continued) ✓

Assistive Wheelchair: average manual chair measures 92 cm height to handles;

devices 76 cm height to armrest; 66 cm width; 106 cm length. (Power chair
dimensions vary greatly and are not included here.)
Cane: used by people who may experience lack of stability or balance.
The foot of the cane may vary according to its application (see tripod
and quadripod below).
Crutch: underarm (wooden and aluminum); primary use for people with
a temporary disability.
Canadian Crutch: underarm rest accompanied with full arm or forearm
handle; for use by people with a permanent injury.
Tripod: cane with three prongs at its foot.

Quadripod: cane with four prongs at its foot.

Walker: used like crutches, with enhanced stability advantage. (Walkers

equipped with wheels or castors are extremely unstable on inclines.)
Disability type Sensory: auditory/vision ✓

Common terms: Conductive hearing loss: usually caused by disease or destruction in the
auditory loss middle ear, and generally not severe.
Sensorineural hearing loss or nerve deafness: damage to the sensory
hair cells or nerve fibers of the inner ear. This loss can range from mild
to severe deafness.
Acquired hearing loss: the sudden or slow loss of hearing in adulthood.
The primary mode of communication for persons with this type of
hearing loss is the spoken language.
Congenital hearing loss: occurs at birth or at a very early age. If
profound, the most common mode of communication is sign language.

30  Building Accessible and Inclusive Environments

 Disability type Sensory: auditory/vision (continued) ✓

Assistive Hearing aid: miniature audio amplifier that increases (all) sound within its
devices: range, including background noise. User must learn to adjust the volume
auditory loss to suit their needs in relationship to ambient noise.
Assistive listening device (ALD): used in addition to, or instead of hearing
aids (some older adults prefer it to a hearing aid). ALDs use infrared light
wave; FM radio wave and magnetic loop induction transmissions which
helps reduce the effects of background noise and reverberation.
Captioning (open, closed, real-time): used primarily in courts, during
government proceedings and by the broadcast industry. This subtitling
service is performed by a trained typist in excess of 225 w.p.m., with a
99 per cent accuracy level. To view it, one’s television must be equipped
with an internal or external decoder chip.
Telecommunication device for the deaf (commonly referred to as TTY):
portable telephone amplifier, which is added on to an existing telephone,
enabling the listener to type and read their messages over phone lines.
Hearing ear dog: companion dogs trained to alert their master to noise –
usually identified by an orange collar and leash.
Sign language interpreters: dedicated person to translate conversation
(not participate in it), trained to maintain confidentiality and discretion
at all times.
Oral facilitator: dedicated person to take spoken words and make them
more visible for those who are lip-reading.
Common terms: Visual acuity: this represents the eye’s ability to perceive detail – more
vision loss specifically, to differentiate between two close points.
Visual field: the entire range the eye can see, extending to 180°, which
is much larger than that of any optical instrument.
Macula: the specialized portion of the retina responsible for colours and
small details, reading and differentiating between faces.
Deaf-blind: people with a dual disability who communicate by finger
spelling on the palm of their hands. Usually accompanied by an
attendant and/or interpreter.

Building Accessible and Inclusive Environments  31

 Disability type Sensory: auditory/vision (continued) ✓

Assistive Cane (rigid or collapsible): white, long and fitted to the individual’s
devices: height and walking style.
vision loss
Service dog: individual preference for animal or cane, not related to
degree of vision loss.
Braille: tactile system of raised dots representing letters of the alphabet
for reading purposes.
Sighted guide: a person who offers their relaxed arm to the visually-
impaired person to grasp, and then leads by announcing such upcoming
features as handrails, doors, stairs, or slopes in the flooring, always
allowing the visually-impaired person time to interpret and react.
Disability type Cognitive: developmental and learning ✓

Assistive Be sure to have the attention of the person while communicating (i.e.
communication maintain eye contact, place bold signage, etc.).
Keep sentences short and clear, and simplify vocabulary as necessary.

Persons with a cognitive disability often confuse up with down, right

with left, back with front, etc. Combine words with images to help
clarify messaging.
Be prepared to repeat and rephrase (i.e. provide adequate destination
signage throughout one’s path of travel).
Pilot test any or all communications endeavors with a focus group, such
as signage or interpretation. Never assume that your intention will be
understood without testing it first.

32  Building Accessible and Inclusive Environments

 Disability type Acquired Brain Injury (ABI) ✓

Common terms Traumatic brain injury: an assault to the brain resulting from a number
of causes including, but not limited to, a motor vehicle accident, a fall,
a sports injury or a job-related accident.
Chronic brain injury: occurs as a result of substance abuse, including the
inhalation of toxic substances or chronic alcoholism.
Pathological brain injury: may involve a viral infection (for example,
Encephalitis), cerebral vascular disease (e.g. a stroke), tumours, cysts or
metabolic disorders (for example, liver or kidney disease).

3.6 Types of barriers
A barrier is an obstacle that makes it difficult
for people to get where they need to go in
life. In other words, environments have the
potential to enable, or disable, all of us. This
subsection details those barriers – from tangible,
to behavioural – that prevent people from
moving forward.

In his book, High Access Home, Charles

Riley III sums up the toll that built environments
have on people with disabilities when he quotes
George Covington, co-chair of the Universal
Design Task Force of the President’s Committee
on Employment of People with Disabilities:
“Most of the elements in our society that define
us as ‘the disabled’ are caused by poor design.
If I cannot find a building’s address because
the numbers are tiny or artistically hidden, I
am ‘visually impaired.’ If a friend of mine in a

3.6.3 Financial barriers
One way to look at financial barriers is to
understand the ways they impede innovation.
If funding is limited, the chance to develop
universally designed projects can be
constrained. Also, if a person with a disability
cannot access, or has limited access to an
environment where they work, live or play,
they will never attain full representation among
the able-bodied people who also use the
space. In turn, low representation disqualifies
financial investment in designing or retrofitting
environments that accommodate individuals
with a disability. It is a “Catch-22” situation.

3.6.4 Systemic barriers

The term systemic barrier refers to situations,
policies and/or practices that unfairly
exclude members of designated groups from
participating in the community. Systemic
barriers are often hard to detect and even
harder to prove. Again, regardless of ability,
many people face systemic barriers and these
will be discussed in Section 4.

The latter two obstacles to universal design,

financial and systemic, apply to both clients –
who may have their quality of life affected by
these barriers – and design professionals – who
may experience challenges negotiating for them
when forwarding the cause of universal design.

4.3 Access to housing

Statistics Canada defines the Presence of
Disability in the Household (PDIH) as at least
one person in the household having long-term
disabilities or activity limitations. According to
2006 Federal census data, PDIH represents 29.3
per cent of all 383,640 households in Calgary
(Statistics Canada, 2006f). Twenty-two per cent
of PDIH households need affordable housing
because they also are low-income and spend
more than 30 per cent of their gross household
income on shelter (Statistics Canada, 2006f).

 4.4 Using public buildings
The Mayor’s Awards for Accessibility recognizes
buildings in Calgary that significantly exceed
the minimum requirements of the Alberta
Building Code for accessibility. The City of
Calgary Access Design Subcommittee chooses
the recipient each year and in 2007, the Calgary
Award for Accessibility was presented to the
Alberta Children’s Hospital.

The Alberta Children’s Hospital was designed

by Kasian Architecture Interior Design and
Planning Limited. Every area of the facility is
accessible by wheelchairs, including exam
rooms, washrooms and playgrounds. Other
features include a playground tree house with
wheelchair access, a parkade with
low-sloped floors for easier wheelchair
and stroller travel, motion-sensored sliding
doors, lowered counters at nurse stations and
reception desks, and low-placed windows and
aquariums (760 mm above floor elevation)
to ensure small children, including those in
wheelchairs, can see the view.

7 Conclusion

Until people find themselves in a situation

where they are disabled due to their
surroundings, they cannot fully appreciate
how the built and virtual environments can
throw obstacles in their paths – and indeed,
profoundly affect their quality of life. In other
words, the spaces where we live, work and play
are absolutely, critically and irrevocably tied to
where we go and what we do.

The concept of universal design is today’s best

practice for design professionals seeking to
eliminate these obstacles. It supports the idea
that the environment needs to be barrier-free for
all groups in society, regardless of ability or age.

While it’s a given that people with disabilities

and older adults benefit more directly from
universally designed projects, it is important
to remember there is a wide range of ability
existing within groups appearing similar. The
concept of universal design maximizes the
idea of people being able to manipulate their
environment to suit individual needs. This
minimizes the need for people to compromise
on living comfortably.

Throughout this handbook, the concept and

practice of universal design is explained and Lastly, while this handbook is primarily intended
extensive examples provided. Four detailed for design professionals, many sections also
checklists are provided to assist design apply to the general public. We all face the
professionals in thinking through each individual challenge of building a better future as our
project that comes across their desk to ensure population ages and changes. It is imperative
important elements are not overlooked. to keep universal design at the forefront of our
own decision-making, be it on a personal level
or in the interest of each other.
