Abstract
This comparative study is based on two surveys conducted in Japan and the United States to understand how facility managers recognize
and practice universal design in their workplaces, and to identify what factors are likely to facilitate or obstruct their practice. The results
showed that, although many facility managers recognized the advantages of applying universal design, most organizations currently provided
accessible workplaces merely within the scope of legal requirements, while few organizations achieved consistency between corporate
mission and strategies, knowledge of facility managers, and the degree of workplace accessibility practices. US organizations and Japanese
organizations showed different perceptions of the issue in terms of advantages of universal design based on differences in management style.
The findings also suggest that an understanding of the issues by top management is key to promoting universal design practice.

1. Introduction
The concept of universal design is currently being
applied to a variety of fields, including architecture and
product design. The underlying reasons for this growing
tendency are the rapid evolution of an aging society in the
developed countries and an increase in the demand of
people with disabilities for full recognition of their civil
rights. In the United States, it is estimated that the
percentage of people age 65 and over will increase from
12.4% in 2000 to 20.7% by 2050, whereas the percentage
of the workforce between the ages of 20 and 64 will
decline from 59.0% in 2000 to 53.4% by 2050 [1]. The
population projection in Japan appears to be even more
radically different. In 2000, the percentage of people age
65 and over was 17.4%; however, it is estimated that the
percentage will increase to 35.7% by 2050. It is further
estimated that the population of the workforce between the

ages of 15 and 64 in Japan will decline from 68.1% in
2000 to 53.6% by 2050 [2]. These statistics imply that
people over 65 will gradually take up a higher proportion
of the workforce. Moreover, as people live longer, they
will be more likely to want to remain in the workforce for
longer. Dynamic demographic changes and increasing
variations in people’s lifestyles will increase the need to
broaden the diversity of the workforce, to include senior
people and people with disabilities.
The employment of people with disabilities remains a
critical issue both in the United States and Japan. In the
United States, the number of workforce-age adults (21–64)
with disabilities was estimated at 30.6 million people or
19.2% in 2000 [3], nearly three times as large as the
percentage of that same group in 1990 [4]. Of this group,
only 56.6% were employed in 2000, which is a significantly
lower employment rate when compared to 77.2% of those
without disabilities who were employed in the same period
[3]. In Japan, the number of non-institutionalized people
aged 18 and over with physical and/or intellectual impair-
ments was estimated to be about 3.5 million or 5.2% of all
workforce-age adults in 2001, which represented an increase
15 (2006) 462 – 478
Y. Saito / Automation in Construction 15 (2006) 462–478 463
of 8.7% since 1996 [5,6]. Of this figure, only 190,000
(5.8%) were actually employed by either the public or
private sectors. Although political and legislative interven-
tions have been broadly implemented in both countries, it is
still necessary to take further action to promote the
employment of people with disabilities.
Meanwhile, many successful organizations have
employed workplace diversity in a broad sense, including
older workers and those with disabilities, as a corporate
strategy to survive intensive business competition [7,8]. For
example, since the early 1990s, IBM worldwide has
developed the ‘‘Workforce Diversity’’ program, one of the
most comprehensive programs for diversity in the current
business world [8,9]. This program is one of the most
important corporate strategies, aimed at reinforcing the
competitiveness of IBM by making the composition of its
employees reflect that of the communities that the company
serves, and by highlighting a variety of individuals’
characteristics, including their physical and intellectual
abilities. Many of the organizations that have implemented
similar workplace diversity strategies have enjoyed both
tangible and intangible benefits from such policies [8,10].
This approach of developing workplace diversity will
definitely transform work environments to a new paradigm
and alter the responsibilities of facility managers for
physical workplaces. Facility managers will be increasingly
required to prepare their workplaces to accommodate the
wider range of workers. Advocates for universal design
argue that it has the potential to facilitate more inclusive
workplaces that will consequently improve organizational
quality; however, very few of those likely benefits have
been actually confirmed by research.
As part of the ongoing research on the effectiveness of
universal design in the workplace, the Universal Design
Research Committee of the Japan Facility Management
Promotion Association (JFMA-UD) conducted two surveys,
one in Japan and the other in the United States. The
purposes of this comparative study are to understand how
facility managers currently recognize and practice universal
design in their workplaces, and to identify what specific
factors are likely to facilitate or obstruct their practice. By
understanding the current state of universal design aware-
ness and practice, this study is intended to be a first step to
inductively identify the outcomes of universal design and, if
its benefits are confirmed, to propose solutions to facilitate
universal design practice among facility managers. Japan
and the United States were chosen as the subject countries
of the surveys because of the different dominant approaches
these two countries employed toward the provision of
building accessibility and the social awareness of disability
and aging (i.e. market-driven in Japan vs. legislation-driven
in the United States). Therefore, we assumed that a
comparative study would help us infer how these two
different approaches could lead to different outcomes. This
paper presents a summary of the results of these two
surveys.
2. Literature review
2.1. What is universal design?
Universal design is defined as the ‘‘design of products
and environments usable by all people to the greatest extent
possible, without the need for adaptation or specialized
design’’ [11]. Applicable to all ages, personal abilities and
sizes, with an inclusive capability that transcends barrier-
free and accessible design, the concept of universal design
was coined in 1985 by Ronald Mace, an architect who had a
disability himself [12,13]. This concept has been accepted in
a variety of design fields, such as architecture, engineering,
product design, and landscape design.
Meanwhile, accessible design and barrier-free design,
which are often considered inappropriately as similar
concepts to universal design, have been broadly recognized
in the field of architecture, mainly through architectural
regulations. Accessibility is defined as a quality of a built
environment to be accessed by people with physical
disabilities and/or older people. Barrier-free design is
defined as a design concept to make a built environment
accessible to people with physical disabilities and/or older
people by removing the architectural barriers present in
existing buildings [13]. These two concepts can be used as
virtually synonymous terms.
From the perspective of disability studies, both universal
design and accessible/barrier-free design can be concep-
tually based on what many scholars call ‘‘the social
construction model of disability’’ [14–17]. Unlike the
medical model or other models that regard disability as a
problem within an individual’s body, this model defines
disability as a product of social interaction, thought, belief,
and language used in a certain culture, and sees social
interventions to increase the mutual understanding of people
as the key to inclusion and participation of people with
disabilities in community activities. According to this
model, universal design and accessible/barrier-free design
are an approach to lower environmental barriers to
participation.
However, there are several theoretical differences
between universal design and barrier-free design/accessibil-
ity. First, while barrier-free design and accessibility are
predominantly associated with the issues of access focusing
on disability, universal design does not necessarily focus
only on disability. Rather, universal design broadly defines
the targeted users and the nature of diversity. Its focus is not
specifically on people with disabilities, but instead on the
inclusion of all types of people in ‘‘one’’ society [9,13,18],
and has argued against the virtual segregation of people with
disability from other social groups by ‘‘special’’ design
interventions [19,20]. Secondly, barrier-free design and
accessibility have been primarily driven by political and
legal interventions [13,21,22]; universal design entails the
power of markets that makes it possible to promote cheaper,
common, and attractive products and environments [23].
Y. Saito / Automation in Construction 15 (2006) 462–478464
Thirdly, standardization is a major means of barrier-free
design and accessibility [24], whereas universal design can
be achieved by maximizing flexibility and adaptability.
Unlike accessibility codes that define prescriptive, stand-
ardized forms of physical environments for ‘‘average’’
people with physical disabilities at the minimum level
[18,21], universal design does not address any specific
form, but presents seven ‘‘performance-focused’’ principles
that require designers to use their creativity to maximize its
applicability to a variety of situations and needs [11,25] (see
Table 1). Lastly, while barrier-free and accessible designs
conceptually regard accessibility as an addition to design
and innately provoke ‘‘Band-Aid’’ approaches to removing
existing barriers, universal design emphasizes the proactive
integration of accessibility and usability to products and
environments as fundamental constructs of design itself
[9,18,20,26]. Thus, universal design always incorporates
accessible design, but not every accessible design can be
regarded as universal design.
2.2. Universal design in the workplace
To date, universal design in architecture has been studied
mainly as an extension of physical accessibility and
usability in public spaces and private houses. In terms of
the workplace, however, the majority of studies have
focused on workplace accessibility and accommodations
as they relate to regulations; only a few studies have
discussed the issues from the perspective of universal
design. Mueller has developed several guidelines to apply
universal design in the workplace from an ergonomic
perspective [27] (e.g., [28,29]). Additionally, Preiser has
discussed the application of universal design to post-
occupancy evaluation of office buildings [30,31].
Table 1
The principles of universal design (source: Ref. [11])
Principles Description
1. Equitable use The design is useful and marketable to people
with diverse abilities.
2. Flexibility in use The design accommodates a wide range of
individual preferences and abilities.
3. Simple and
intuitive use
Use of the design is easy to understand,
regardless of the user’s experience, knowledge,
language skills, or current concentration level.
4. Perceptible
information
The design communicates necessary
information effectively to the user, regardless
of ambient conditions or the user’s sensory
abilities.
5. Tolerance for error The design minimizes hazards and the adverse
consequences of accidental or unintended
actions.
6. Low physical effort The design can be used efficiently and
comfortably, and with a minimum of fatigue.
7. Size and space for
approach and use
Appropriate size and space is provided
for approach, reach, manipulation, and use,
regardless of the user’s body size, posture,
or mobility.
JFMA-UD has also established guidelines to develop the
strategies of ‘‘workplace universal design’’ in conjunction
with corporate management [9]. The study attempts to define
the conceptual framework of workplace universal design
[9,32].While public spaces tend to apply the highest common
solutions to benefit a broad range of unknown users as a
whole, workplaces generally target specific users (employ-
ees). The quality of workplace universal design can be further
enhanced by personal, on-site, case-by-case measures, to-
gether with flexible and adaptable ways of meeting the needs
or preferences of individual workers. Therefore, in addition to
the general sense of universal design, the framework attempts
to broadly encompass a barrier-free approach for adapting the
existing environments to the needs of people with disabilities,
personal assistance as a supplement to physical accommo-
dations, and environmental customization (e.g. assistive
technology) that will be needed by each worker to accomplish
their jobs. In other words, workplace universal design not
only considers the collective needs of a group, but also
remains sensitive to individual needs.
Existing studies do not provide much information about
the confirmed evidence of benefits from universal design in
the workplace, although some peripheral work shows its
potential advantages. For example, a study by the U.S.
Occupational Safety and Health Administration (OSHA)
shows that the injury incidence rates of the companies that
adopted OSHA’s ergonomics guidelines were less than half
the average industrial rate [33]. These companies proved
that workers’ compensation costs could be reduced by more
than 80%. The Job Accommodation Network also revealed
that ‘‘for every $1 spent on job accommodation, the
employer gets back $26 in savings’’ in terms of workers’
compensation and other disability benefits costs ([27]; cf.
[10]). Many other studies in ergonomics show that proactive
interventions can improve the organizational bottom line by
preventing workplace injury and illness, decreasing work-
ers’ absenteeism and sick leave, and improving workers’
retention in organizations (e.g. [34–36]).
Meanwhile, the study by Loprest and Maag shows that in
1995, the employment rate of those with disabilities who
needed some accommodations to work (66%) was lower
than those who did not require any special accommodations
(75%), which was also very close to the employment rate of
those without disabilities at that time (79%) [37]. This result
implies that it would be possible to improve employment
opportunities for people with disabilities if organizations
already prepared workplaces that could accommodate those
people as far as possible, without ‘‘special’’ arrangements
that would require additional expenses for the organizations.
Other studies indicated that some large companies that had
been actively making their workplaces accessible agreed
that workplace accessibility increased productivity and
profitability by allowing them to diversify their employees.
Some examples of the reported benefits included flexibility
in employment, high motivation of people with disabilities,
and better understanding of customer needs (e.g. [8,10,38]).

However, most studies within the context of workplace
accommodations have focused solely on people with
disabilities and are less likely to explore the potential
benefits for a variety of workers in inclusive ways. JFMA-
UD pointed out the probable impact of workplace universal
design on organizational outcomes, including the improve-
ment of corporate images and an increase in the asset value
of facilities [9], but these impacts have not been empirically
proven yet.
2.3. Awareness of universal design among practitioners
The concept of universal design first appeared about two
decades ago, and it is interesting to see how practitioners
now recognize it and to what extent they have applied it to
their practices. In the field of product design, Vanderheiden
and Tobias studied the motivators and barriers to the
implementation of universal design, as well as possible
strategies to improve the awareness of universal design [39].
Another relevant study is Bruyere’s study regarding the
practices of both private companies and U.S. Federal
agencies in providing reasonable accommodations for
employees with disabilities in the workplace [40]. Although
this study does not focus primarily on universal design, but
rather on the implementation of Title I of the Americans
with Disabilities Act of 1990 (ADA), these surveys asked
human resource professionals about accommodations that
they provided in their workplaces and the obstacles they
faced in providing those accommodations. These two
studies revealed the present state of awareness and practices
of universal design among practitioners in specific fields;
however, there has been no study from the perspective of
facility management. The question still remains—what are
the similarities beyond the fields, and what issues are
peculiar to facility managers?

3. Research methodology and overview
The two surveys in Japan and the United States targeted
in-house facility managers and used a self-administered
questionnaire with multiple-choice questions. The question-
naires basically featured the same question and answer
options, so that the surveys’ results could be compared.
However, the options for answers in several questions were
adjusted to reflect the circumstances of each country (for
example, the difference in legal requirements) and some
additional questions were included in the questionnaire for
the US survey.
The main focus of both surveys was on the following five
perspectives:
(1) Attitudes about the employment of diverse workers,
including older workers and those with disabilities;
(2) the degree of the recognition of universal design;
(3) the degree of the practice of universal design;
(4) advantages and disadvantages of applying universal
design; and
(5) current obstacles to the introduction of universal
design.
Since we had assumed that barrier-free design and
accessible design were more popular terms than universal
design, some questions were designed to identify the
differences in the recognition of these terms comparatively.
The definitions of both barrier-free/accessible design and
universal design were given survey participants in the
beginning of the questionnaires to establish a common
ground among the participants to answer questions.
3.1. Overview of the survey in Japan
The first survey was conducted in Japan from January 29
to February 14, 2003. The digital format of the question-
naire consisting of 14 questions was distributed via e-mail to
3033 facility managers who subscribed to the Japan Facility
Management Promotion Association’s (JFMA) e-mailing
list. Completed questionnaires were returned to JFMA via
fax or e-mail.
Of those who received the questionnaire, 62 persons
(2.1%) provided valid responses. Regarding the profiles of
the respondents (see Table 2), 89% of the respondents
worked for ‘‘Japanese organizations,’’ which were defined as
Y. Saito / Automation in Construction 15 (2006) 462–478466
organizations with more than half of their capital originating
in Japan. The other 11% represented ‘‘international organ-
izations’’ that were based in Japan but whose major capital
came from other countries. In terms of industry representa-
tion, 74% of the respondents belonged to service industries,
18% worked in manufacturing, and 7% worked in govern-
ment agencies, education, or other organizations. Thirty-one
percent of the respondents worked for organizations with
fewer than 100 occupants on site, 42% came from
organizations with between 100 and 999, and 23% of them
worked for organizations with 1000 occupants or more.
Regarding the type of building occupancy, 40% of the
workplaces surveyed were owner-occupied, 19% were
leased buildings occupied entirely by the respondents’
organizations, and 36% were leased buildings partially
occupied by the respondents’ organizations.
3.2. Overview of the survey in the United States
The second survey was conducted in the United States
from May 25 to June 7, 2004, in collaboration with the
International Facility Management Association (IFMA). An
on-line questionnaire with 17 questions was developed, and
e-mail invitations were sent out to about 1400 IFMA
members who worked as in-house facility managers in the
United States. Respondents were invited to fill out the
questionnaire online.
The number of valid responses was 128, which means
9.1% of those who received the e-mail invitation responded.
Regarding their profiles (see Table 2), 64%of the respondents’
organizations had their headquarters in North America, and
35% failed to answer this question. In terms of industry
representation, 35% of the respondents belonged to service
industries, 15%worked inmanufacturing, and 14%worked in
government agencies, education, or other organizations; 36%
failed to answer this question. Two percent of the respondents
worked for organizations with fewer than 100 occupants at
their workplaces; 39% worked for organizations whose
workplaces housed between 100 and 999 occupants, and
22% were from workplaces with 1000 or more occupants;
37% were unknown. Regarding the type of building occu-
pancy, 34%of theworkplaces surveyedwere owner-occupied,
9% were leased buildings occupied entirely by the re-
spondents’ organizations, 16%were leased buildings partially
occupied by the respondents’ organizations, and 6% indicated
other types of building occupancy; 35% were unknown.
4. Findings and discussion
4.1. Attitudes about the employment of diverse workers
4.1.1. The current state and expected change of the
employment of diverse workers
In Japan, 0.3% was the current average rate of the
number of workers with physical disabilities among overall
employees in an organization; 1.5% was that of the
number of older workers (over 65), and 2.5% was that
of the number of so-called ‘‘non-traditional’’ workers,
which included workers with psychiatric, intellectual, and
cognitive disabilities, foreign workers who have difficulty
in communicating in a common language in a given
country, female workers who are pregnant, and those who
have extremely large or small physiques compared to the
average, in addition to older workers and those with
physical disabilities. In the United States, the current
average rate of the number of workers with physical
disabilities among overall employees was 2.4%; 4.3% was
that of the number of older workers, and 19.0% was that
of the number of non-traditional workers in total (see Table
3). These results indicate that US organizations are more
likely than Japanese organizations to have positive
attitudes regarding the employment of a diverse workforce.
Specifically, when compared to the fact that the Japanese
national average rate of the number of workers with
physical and intellectual disabilities among overall employ-
ees in an private organization was 1.49% in 2001 [41],
there is a possibility that workers with disabilities are
segregated in particular workplaces and have few oppor-
tunities to be integrated into and work with ‘‘traditional
workers’’.
Regarding the expected change in the number of non-
traditional workers in surveyed workplaces in the future (see
Table 3), most of the US respondents answered with ‘‘no
change’’ or ‘‘minor increase’’ in each of the given groups. In
Japan, while 60% of the respondents were positive about
hiring people with disabilities in the future, more than 50%
of them thought that it would be unlikely that their
organizations would increase their quota of older employ-
ees. This attitude reflects, in part, the tendency of Japanese
companies to lower the retirement age.
Incidentally, there is no statistically significant correla-
tion between the current employment rate and the expected
degree of employment change in future. This means that
organizations would not necessarily increase the total
employment opportunities for non-traditional workers even
if they currently employ these workers positively. The
reasons for this tendency need to be investigated further
with additional research.
4.1.2. Relationship between corporate missions and the
employment of diverse workers
Eighteen percent of the Japanese respondents answered
that the concept of diversity was a part of their corporate
mission, whereas 79% of their US peers said their corporate
mission included diversity (see Fig. 1). This result reveals
that US organizations are more likely than Japanese
organizations to have positive attitudes about hiring diverse
workers and leverage such resources to organizational
effectiveness. This tendency apparently reflects a difference
in socio-environmental structure between Japan and the
United States.

However, neither the Japanese nor the US survey results
show a statistical significance of relationships between the
likelihood of including diversity in corporate missions and
the employment ratio of overall non-traditional workers,
nor the expected degree of future change in the employ-
ment of these workers. Therefore, this finding suggests that
inclusion of diversity in corporate missions does not
necessarily expand employment opportunities for these
workers. A possible reason for this result is that,
particularly in the United States, many organizations may
define diversity in a narrow sense—simply racial and
gender diversity. The other possible reason is that
organizations may prioritize the hiring of applicants
competent to meet organizational needs regardless of age
or physical ability; thus the number of non-traditional
workers is just a coincidental result. In either case, it
would be a valuable challenge in both Japan and the
United States to reveal the value of reconstructing the
positive utilization of such diverse human resources from

4.2. The degree of the recognition of universal design
The survey results show that the terms barrier-free
design and universal design were well known among
Japanese facility managers, although universal design was
less familiar than barrier-free design. Ninety-two percent of
the respondents said that they were well acquainted with
barrier-free design; 77% said they were very familiar with
universal design. Meanwhile, US facility managers were
familiar with the term barrier-free design or accessibility,
but universal design was not well-known. Sixty-eight
percent of the respondents answered that they were very
familiar with barrier-free design or accessibility, but only
28% said they knew universal design well (see Fig. 2).
It is easily assumed that the recognition of barrier-free
design or accessibility is an effect of the accessibility

regulations in both countries (e.g., in Japan, The Law for
Buildings Accessible to and Usable by the Older and
Physically Disabled Persons [known as the Heartful Build-
ing Law]; in the U.S, The Americans with Disabilities Act
of 1990 [known as the ADA]). However, despite the longer
history of accessibility regulations in the United States when
compared with Japan, and the fact that the concept of
universal design was originally coined in the United States,
the familiarity with the terms barrier-free design/accessi-
bility and universal design in the United States was much
lower than in Japan. Specifically, compared to the result in
Japan, the unfamiliarity of universal design among US
facility managers was significant. The popularity of these
terms in Japan can be explained, in part, by a recent boom in
the field of product design, in which many manufacturers
and advertising agencies have focused on the concept of
universal design as a new marketing strategy to recover
from the long business recession. The recent amendment to
the Heartful Building Law could be another explanation for
the increase in the popularity of these terms in Japan. It is
still uncertain, however, why these terms are less familiar to
US facility managers, and the subject should be investigated
in more depth.
Regarding the relationship between the ratio of non-
traditional workers and familiarity with these terms, the US
survey results show that the higher the ratio of non-
traditional workers to overall employees in a workplace,
the more likely it was that the facility manager who worked
in that workplace was familiar with barrier-free design/
accessibility and universal design (Spearman’s q (54)=
+.30, p =<.05 [barrier-free/accessibility]; q (54)=+.39,
p =<.01 [universal design]).
Meanwhile, in Japan, the respondents whose workplaces
partially occupied leased buildings were less likely than
those who worked in owner-occupied buildings to be
familiar with barrier-free design (Mann–Whitney U test:
z =�2.50, p =<.05). The most likely explanation for this
finding is that in many cases of partially leased buildings,
facility managers are less likely to tackle building accessi-
bility regulations because these regulations are applied to
spaces for which those facility managers are often not
responsible.
4.3. The degree of practice of universal design
4.3.1. The degree of applying universal design to workplace
policies
Forty-seven percent of the Japanese respondents
answered that their organizations had incorporated universal
design and/or barrier-free design into their workplace
policies, although universal design was less likely than
barrier-free design to be integrated into those policies (18%
vs. 35%, respectively). Ten percent of the Japanese
respondents said that their organizations had prepared
workplace planning manuals that contained the criteria of
universal design and/or barrier-free design. In the United
States, 71% of the respondents’ organizations applied
universal design and/or barrier-free design/accessibility to
their workplace policies (17% for universal design; 60% for
barrier-free design/accessibility); 23% of the respondents
answered that they had workplace planning manuals with
universal design and/or barrier-free design/accessibility
guidelines (see Fig. 1). Obviously, US organizations are
more likely than their Japanese counterparts to have already
applied universal design and/or barrier-free design/accessi-
bility to their workplace policies and planning manuals.
However, survey results in both Japan and the United
States show no statistically significant correlations between
the existence of diversity in corporate missions and the
integration of universal design or barrier-free design/
accessibility into workplace policies and workplace plan-
ning manuals. This implies that a corporate mission
regarding diversity is not necessarily reflected in workplace
policies and planning manuals.
US organizations that have applied universal design and/
or barrier-free design/accessibility to their workplace poli-
cies are more likely to show a higher ratio of workers with
physical disabilities to overall employees (Mann–Whitney
U test: z =�1.98, p =<.05). Meanwhile, in Japan, facility
managers whose workplaces are owner-occupied buildings
are more likely than those in partially leased buildings to
answer that their organizations have workplace policies
associated with universal design and/or barrier-free design
(Pearson v2 (2, N =59)=7.35, p =<.05). Japanese work-
places that house more occupants are also more likely to
Y. Saito / Automation in Construction 15 (2006) 462–478 469
include universal design and/or barrier-free design in their
policies (Mann–Whitney U test: z =�3.06, p =<.01).
4.3.2. The degree of current practice of universal design
Only 20% of the Japanese respondents said that their
workplaces currently provided universal design and/or
barrier-free design beyond the legally required level;
whereas 34% said that their workplaces provided only the
minimum of legally required barrier-free design. In the
United States, a majority of the respondents (59%) answered
that their workplaces currently complied with the minimum
requirements of the Americans with Disabilities Act
Accessibility Guidelines (ADAAG). Twenty-eight percent
of the respondents said that their workplaces provided more
than the legally required level of barrier-free design/
accessibility, but only 2% of the respondents answered that
universal design was provided in their workplaces (see Fig.
3). This tendency is probably related to the unfamiliarity
with the term universal design in the United States.
Although there is a large difference in the percentage of
the respondents who answered that they provided any
physical workplace accessibility (54% in Japan vs. 89% in
the US), there is no statistically significant difference among
those who explicitly described their current level of practice
(Japan N =34; US N =113) in the distribution of levels of
practice between these two countries.
There are no statistically significant correlations between
the degree of current practice of universal design or barrier-
free design/accessibility and the familiarity of facility
managers with universal design. However, the results of
the US survey show a correlation between the degree of
current practice of universal design or barrier-free design/
accessibility and the familiarity of facility managers with
barrier-free design/accessibility (Spearman’s q (111)=
+.23, p =<.05). Meanwhile, the Japanese survey results

reveal that the more occupants in a workplace, the more
likely it was that the organization of that workplace
provided a higher level of universal design or barrier-free
design/accessibility (Spearman’s q (30)=+.39, p =<.05). In
addition, in both Japan and the United States, although the
results did not prove a significant difference in the degree of
current practice of universal design or barrier-free design/
accessibility based on the employment rate of non-tradi-
tional workers and the inclusion of diversity in corporate
missions, organizations that applied universal design and/or
barrier-free design/accessibility to their workplace policies
were more likely to practice a higher degree of universal
design or barrier-free design/accessibility in their work-
places (Mann–Whitney U test: z=�2.57, p =<.05 [US];
z =�2.37, p =<.05 [Japan]). Combined with the positive
correlation between the application of universal design and/
or barrier-free design/accessibility to workplace policies and
the employment rate of people with disabilities, this result
suggests that having workplace policies that include
universal design and/or barrier-free design/accessibility
could be key to enhancing both the employment of people
with disabilities and the practice of workplace universal
design/accessibility.
The results of this question generate two important
discussions when combined with the previous findings.
First, the familiarity of Japanese facility managers with
universal design or barrier-free design/accessibility does
not mean that they have subscribed to its practices. They are
less likely than their US counterparts to practice universal
design and/or barrier-free design/accessibility in their work-
places, even though they are more familiar with these
concepts. Moreover, many of the Japanese respondents
(34%) did not grasp the present state of their practice on this
issue, which implies that they know these concepts better,
but pay less attention to these practices than US facility

managers (this implication is also supported by the low
response rate of the Japanese survey, which suggests, in
part, a relatively indifferent attitude of Japanese facility
managers toward this issue). One reason for this difference
can be associated with the low employment rate of older
workers and those with disabilities in Japan; most Japanese
facility managers seem not to have much opportunity to
interact with those workers in their workplaces. The
difference in legal environments can also explain this
attitude of Japanese facility managers. Unlike US accessi-
bility laws, the Heartful Building Law has just been
amended to mandate the provision of accessibility to
specified types of buildings, in which, importantly, office
buildings are not included and they are still ‘‘voluntarily
obligated to make an effort’’ to provide accessibility. From
this argument, we can assume that legal intervention is
likely to be an effective way to promote accessibility and
usability for diverse workers.
However, the second discussion is evoked when we look
at the relationships between the degree of applying universal
design and/or barrier-free design/accessibility to workplace
policies, the nature of the actual practice, and its familiarity
in the US survey (higher practice but low familiarity). It is
possible that some US organizations adopt barrier-free
design/accessibility to their workplace policies and practice
it just because it is obligated by laws, such as the ADA,
rather than as a positive application that supports corporate
missions and strategies based on the real understanding of
user needs or effectiveness for their own organizations. This
is also supported by the facts that the majority of the survey
respondents indicated that they provided only the minimum
requirements stipulated by accessibility regulations, and that
fewer respondents’ organizations seemed willing to provide
accessibility beyond what the regulations required. This is
consistent with Stein’s argument that prescriptive legal
specifications often lead to misunderstandings by designers
and building owners that the regulations are sufficient and
definite. Those misunderstandings keep them from fully
investigating the real needs of people with disabilities, and
from finding the actual insufficiencies and inconsistencies
of the current provision of accessibility [42].
Therefore, it is necessary to establish effective
approaches to the strategic application of universal design
for the organizational effectiveness of both Japanese and US
facility managers. It is important to develop solutions to

4.3.3. The expected degree of future practice of universal
design
Regarding the expectation of future practices, 34% of the
Japanese respondents expressed their desire to provide
universal design and/or barrier-free design beyond the
legally required level in the future, whereas 29% of the
respondents answered that they would prepare their work-
places at the minimum legal level of accessibility require-
ments. In the United States, 31% of the respondents said that
their future workplaces would fulfill the minimum of the
legally required accessibility; 28% expected that they would
practice universal design and/or a higher level than the legal
requirements of accessibility in their workplaces (see Fig.
3). Of those who explicitly answered the questions about
both current and future practices (Japan N =32; US N =73),
31% of the Japanese respondents said they would increase
the level of practice, 69% expected to keep the current level
of practice, and no one said the level of practice would
decrease. In the United States, 23% of the respondents said
that they would pursue the higher level of practice, 74%
expected no change, and 3% indicated their workplaces
would provide a lower level of accessibility (see Fig. 4).
According to these results, although the majority in both
countries expected ‘‘no change’’ in terms of their practices,
Japanese organizations seemed somewhat more willing than
US organizations to improve their level of practice in the
future. This tendency can be partially related to the recent
amendment of the Heartful Building Law and the current
boom of universal design in Japan.
The relationship between the expected degree of future
practice and whether a corporate mission currently stated
diversity is not statistically significant. In the United States,
the results show that the more organizations expected an
increase in the number of employees with physical
disabilities, older workers, and other non-traditional workers
in their workplaces, the more they were willing to provide
the advanced levels of workplace accessibility in the future
(Spearman’s q (50)=+.28, p =<.05). The Japanese survey
also indicates that the expected degree of future practice was

number of older employees and those with physical
disabilities (Spearman’s q (31)=+.39, p=<.05). Statistical
analyses show, however, that in both countries, the expected
increase in the number of non-traditional workers does not
seem to necessarily lead to organizations’ willingness to
upgrade workplace accessibility.
4.4. Advantages and disadvantages of applying universal
design
4.4.1. Anticipated advantages of applying universal design
In Japan, the anticipated advantages that the respondents
most frequently cited were: ‘‘enhancement of a corporate
image and/or reputation (60%),’’ ‘‘more flexibility in
employment of diverse workers (55%),’’ and ‘‘improvement
of employee satisfaction and/or productivity (50%).’’ Only
13% of the respondents expected ‘‘an increase of facilities’
asset values,’’ indicating that not many Japanese facility
managers recognized the relevance of universal design to
asset management. Meanwhile, the US respondents most
frequently said that the application of universal design
would ‘‘allow us more flexibility to employ diverse workers
(56%),’’ ‘‘improve employee productivity and/or satisfaction
(50%),’’ and ‘‘enable us to reduce legal risks and/or workers
compensation claims (50%).’’ Forty-three percent of the
respondents also cited that it would ‘‘reduce alteration and
maintenance costs’’ (see Fig. 5).
Although the respondents of both surveys showed that
they largely expected that universal design would allow
them more flexibility in employment and improve worker
satisfaction and productivity, it seems that US facility
managers are more likely than those in Japan to expect

Fig. 5. Expected advantages of applying un

benefits from the application of universal design, such as a
reduction in legal risks. On the other hand, Japanese facility
managers are more likely than their US peers to expect
benefits from indirect, intangible, and longitudinal perspec-
tives, such as the improvement of a corporate image. This
tendency is a reflection, in part, of the differences in
management style between Japan and the United States.
The advantages frequently cited by the US facility
managers pertaining to organizations that currently provided
more than the legally required level of accessibility in their
workplaces (N =31) include ‘‘enhancement of a corporate
image/reputation,’’ ‘‘improvement of customer satisfaction,’’
and ‘‘a reduction in alteration and maintenance costs,’’
following three advantages shown above (flexibility in
employment, improvement of employee productivity and/or
satisfaction, and a reduction in legal risks and/or workers
compensation claims; see Fig. 6). Because these frequently
cited advantages are based on the experiences of facility
managers practicing universal design/accessibility, it is
highly possible that these are actual benefits derived from
the application of universal design, although further study
regarding this point is still needed.
Meanwhile, overall, US facility managers were more
likely than their Japanese counterparts to cite the wider
range of advantages of universal design application, which
suggests that they are more likely to expect multifaceted
benefits from universal design. In addition, the US
respondents who recognized more advantages were more
likely to answer that they would upgrade the levels of
workplace accessibility in the future (Spearman’s q (67)=

single significant benefit would motivate organizations to
improve their level of applying universal design, but based
on the above findings, it is possible that proving that the
application of universal design would bring a variety of
benefits could be a trigger to improve organizations’ level
of practice. Moreover, those who showed their willingness
to raise the degree of universal design/accessibility practice
in the future were more likely to cite ‘‘improvement of
worker satisfaction/productivity’’ and ‘‘a reduction in legal
risks/workers compensation claims’’ as the expected
advantages of universal design (Pearson v2 (2, N =73)=
8.78, p=<.05 [satisfaction/productivity]; v2 (2, N =73)=
8.78, p=<.05 [legal risks/compensation]. This implies that
these two aspects could become strong facilitators to
enhance universal design practice or reasons for applying
universal design.

In both countries, many facility managers regarded cost
issues as major disadvantages in applying universal design.
In Japan, the most frequently cited disadvantages expected
include ‘‘an increase in construction costs (55%)’’ and
‘‘inefficiency of space usage (37%).’’ The US respondents
also most frequently cited that it would ‘‘increase con-
struction costs (39%)’’ and ‘‘reduce the efficiency of usable
area (18%)’’ (see Fig. 7). However, US facility managers
were less likely than their Japanese peers to be concerned
about cost issues. This could be because land prices in the
United States are less expensive, and the percentage of rent
or allowance for depreciation of facilities in overall facility
operation costs is lower than that in Japan. In addition,

managers are likely to perceive that applying universal
design would make initial construction costs higher, but that
it would lower facilities’ running costs. Incidentally, the US
facility managers who were less willing to increase the
degree of their practice of universal design/accessibility
were more likely than those who showed positive attitudes
regarding improvement of workplace accessibility to be
concerned about weakening the efficiency of space usage as
a result of applying universal design (Pearson v2 (1,
N =74)=6.38, p=<.05); in effect, the anticipated space
inefficiency, which would increase facilities’ occupancy
costs, seems to be the greatest demotivator.
However, there is a possibility that the concern about an
increase in construction costs is a myth that results from
confusion between barrier-free design/accessibility and
universal design. Although little explicit research has been
done on this issue, many universal design advocates have
argued that there would be no significant increase in initial
construction costs if universal design were integrated from
the first stage of planning. A study done by Cluff showed
that even adding accessibility features would increase an
initial construction budget by only 5%, and this figure
would be much less if universal design features were
included from the beginning of a project [10]. The question
regarding cost issues needs to be further investigated, but it
is possible that this negative perception is associated with a
lack of accurate knowledge based on actual evidence
regarding universal design. In fact, US facility managers
who answered that they were familiar with the term
universal design are less likely than those unfamiliar with
the term to regard an increase in construction costs as a
disadvantage (Pearson v2 (1, N =112)=8.62, p =<.01).
On the other hand, 34% of the Japanese respondents and
20% of the US respondents said that no disadvantages were
expected; more facility managers than had been assumed
anticipated that universal design would not bring any
negative effects to organizations. However, a statistical
analysis also shows that there is no correlation between
whether respondents mentioned that no disadvantages were
expected and the degree of their practice in the present or in
the future. This result implies that they are prevented from

disadvantages.
4.5. Obstacles to the introduction of universal design
As we had assumed, the major obstacle in introducing
universal design to the workplace was ‘‘cost issues;’’ 78% of
the Japanese respondents cited it. On the other hand, in the
United States, only 54% of the respondents regarded ‘‘cost
issues’’ as an obstacle, followed by ‘‘a lack of experience/
knowledge (37%),’’ and ‘‘understanding by executives
(32%)’’ (see Fig. 8). This is consistent with the result of
expected disadvantages, specifically in terms of the problem
with higher rent and land prices in Japan.
This result is very interesting when we compare it to the
result of Bruyere’s survey in which she asked human
resource professionals about barriers to employment for
people with disabilities [12]. This survey showed that the
biggest concern for human resource professionals was a lack
of experience and that they did not care about cost issues as
much as the facility managers did in our surveys. Therefore,
from a facility management perspective, even though
facility managers are often biased toward cost issues
associated with applying universal design as pointed out
in the above discussion, it will be particularly important to
seek solutions to cost issues through a variety of efforts,
such as financial incentives. As some of the respondents in
the US survey mentioned, the marketing efforts of suppliers
to provide better services and materials at a low price will
also be effective; marketability is, in fact, one of the
fundamental principles of universal design.
Another interesting finding from the US survey is that
those who currently provided more than the legal require-
ments of accessibility were less likely to regard ‘‘under-
standing by executives’’ as an obstacle (Pearson v2 (1,
N =105)=4.13, p =<.05). It can be inferred, therefore, that

level of accessibility to their workplaces because they did
not have to make a robust effort to convince their superiors.
If this is the case, it can be concluded that top managers
holding certain values and beliefs would have a substantial
impact on lowering the threshold to adopt innovative
concepts, such as universal design. This is consistent with
two other studies: Bruyere found that a visible top
management commitment was regarded as the most
effective strategy to reduce barriers to provide workplace
accommodation [40]; Vanderheiden and Tobias’s study also
showed that support from upper management is key to
implementing universal design [39]. This conclusion evokes
another prospective research question—how can the values
and beliefs of top managers facilitate the introduction of
universal design?
5. Conclusion
Through these two surveys in Japan and the United
States, we found that overall many facility managers in both
countries recognized the advantages of applying universal
design in their workplaces and practice it at any levels. It
should be noted that this study has a limitation in terms of
its generalizability due to the small response rate and a
possible sampling bias. However, as far as we know, this is
a pioneering study that looks at the current state of universal
design awareness and practice in the workplace, and
provides many important implications for future research
in terms of the impact of universal design on organizations
and strategies to promote more inclusive workplaces.
First, the surveys showed that most organizations
currently provided accessible workplaces only within the
scope of the legal requirements, and that there is a
significant possibility of being able to improve their
universal design practices. There were few organizations
that have achieved consistency between corporate missions,
human resource strategies, workplace strategies, knowledge
of facility managers, and the degree of workplace accessi-
bility practices. It will be necessary for organizations to seek
further development of internal alignment between these
aspects. Specifically, for Japanese organizations, it will be
important that they increase their interest in promoting
workplace diversity and actively practicing universal design
based on organizational strategies and culture. US organ-
izations will need to rethink the meaning and impact of
universal design/accessibility on their workplaces from a
strategic perspective, beyond the traditional perception of
mere legal obligation.
Secondly, in response to the findings about the advan-
tages and disadvantages, it will be necessary to develop
solutions to the cost-related issues involved in applying
universal design, such as political and/or marketing inter-
ventions and efforts to promote proper knowledge that can
disprove biased perceptions among practitioners. Because
this study has the limitation of explicitly addressing causal
relationships between perceived advantages and practices, it
is also necessary to verify whether the positive perception
regarding the advantages of universal design truly leads to
action. In addition, it would be interesting to study to what
extent organizational environmental factors, other than the
scope of this study, affect universal design practice, such as
leadership, beliefs of top management, and corporate values
and culture. Specifically, the findings of this study show that
the understanding and commitment of top management is a
key to driving universal design practice, so it will be
important to seek ways to increase understanding of the
issues by executives.
Lastly, according to the findings from the US survey,
accessibility regulations have played a significant role in
facilitating workplace accessibility. However, it could be
disputed whether people with disabilities are satisfied with
the current accommodations developed based on existing
accessibility codes. As Connell and Sanford pointed out
[20], it will be necessary to assess to what extent these legal
frameworks have been effective and had positive impacts on
the work life of not only people with disabilities, but also
their colleagues without disabilities. In addition, it will be
important to look at what are the facilitators that lead
organizations to action beyond the scope of the regulations,
and what differences in outcomes can be observed between
organizations that merely comply with accessibility regu-
lations and ones that proactively practice universal design.
In order to further promote universal design practices in
the workplace, it will be important to verify the advantages
and disadvantages of universal design practice addressed in
this study from real case studies, and to collect data that can
be used for decision-making by facility managers and
corporate executives. This will be our next goal, and we
hope to present several case studies on the topic in the near
future.
