星辰棋牌官网Accessibility laws like the Architectural Barriers Act (1968), Section 504 of The Rehabilitation Act of 1973, the Fair Housing Act Amendments (1988), and the Americans with Disabilities Act (1990) establish minimum requirements that protect people with disabilities from discrimination in the built environment. Ron Mace, FAIA and Ruth Hall Lusher, saw the need to reevaluate using legal mandates to ensure usability by people with disabilities based on their experience with accessibility laws. Universal design, the term for this revised approach, was based on the premise that the environment could be much more accessible than the minimum requirements of law required if designers focused attention on improving function for a large range of people.
Universal design (UD) is also called inclusive design, design for all, or life span design. As initially conceived, UD was focused on usability issues. "The design of products and environments to be usable by all people, to the greatest extent possible, without the need for adaptation or specialized design" (Mace, 1985). In the last ten years, the emphasis was broadened to wider issues of social inclusion. A newer definition is more relevant to all citizens without ignoring people with disabilities. It states that universal design is, "a process that enables and empowers a diverse population by improving human performance, health and wellness, and social participation" (Steinfeld and Maisel, 2012). In short, universal design makes life easier, healthier, and friendlier for all.
Universal design increases the potential for developing a better quality of life for a wide range of individuals. It also reduces stigma by putting people with disabilities on an equal playing field. While it does not substitute for assistive technology, universal design benefits people with functional limitations and society as a whole. It supports people in being more self-reliant and socially engaged. For businesses and government, it reduces the economic burden of special programs and services designed to assist individual citizens, clients, or customers.
Proponents of universal design must recognize that products and environments can never be fully usable by every person in the world, but that services, management practices, and policies can benefit from universal design thinking. Universal design should therefore be considered a process rather than an end state. There is never any end to the quest for improved usability, health, or social participation, so attention to more than just the built environment is needed to achieve these three broad outcomes.
星辰棋牌官网The following table provides some examples of the differences between universal design and accessible design.
|A universally designed home plan costs the same as any other plan to build that anyone can purchase||A custom designed home based on an existing plan but requires additional costs for the redesign and custom construction details|
|Home improvement services that incorporate universal design as a basic service||Home modifications services by a contractor who charges more for her specialized knowledge of design for disability and aging|
|Automobile instruments and controls customizable to accommodate differences in perceptual abilities, stature, motor abilities, and preferences||Assistive technology used to adapt an automobile display for people with special needs|
|A no step building entry that everyone can use easily and together||A building entry with a ramp at the side that is out of the way for all visitors but is accessible by code|
|A hotel that has 100% universally designed rooms in a variety of types||A hotel that has only the code-required percentage of accessible rooms|
星辰棋牌官网The "Principles of Universal Design" were developed by a team of U.S. experts organized by the Center on Universal Design at NC State University in the 1990's. Accompanied by a set of guidelines for each Principle, they were a valuable tool for clarifying universal design for early adopters, and are still widely used today.
The Principles of Universal Design:
星辰棋牌官网The eight Goals of Universal Design were recently developed in an effort to update the Principles, clarify the concept of universal design, incorporate human performance, health and wellness, and social participation as outcomes, and address contextual and cultural issues. For example, there are many sources of contextual differences, such as topography, economic development levels, cultural norms, and local values, which influence the way designers implement universal design. Increasingly, high value is placed on preserving cultural resources like historic buildings and natural resources. Attempts to enhance accessibility, however, often conflict with these two goals. Universal design must address this conflict to overcome perceptions that it gets in the way of reaching other important design goals.
One barrier to adoption of universal design in middle- and low-income countries is the perception that it is often perceived as idealistic, expensive, or an imposition of Western values. It is realistic and appropriate to acknowledge that design strategies will differ or be adapted in different places and by different cultures. In some places, achieving the level of accessibility required by Western norms could be counterproductive. Thus, it is important that universal design strategies also address cultural values associated with social, economic, and physical context. In addition to addressing these concerns, the eight Goals of Universal Design were also conceived to link universal design to bodies of knowledge and identify measurable outcomes.

As a result of UD's growing popularity, many new issues have captured the attention of design professionals and their colleagues in related professions. Those issues with a close relationship to universal design include aging in place, sustainability, workplace design, public spaces, and social justice. Universal design has much to contribute to solving any social problem in which usability and social participation play a major role in design response.
Aging in Place: A large majority of individuals want to age where they currently live. A 星辰棋牌官网 of adults over the age of 65 found that almost 90 percent want to remain in their own home for as long as they are able and 80 percent anticipated permanently living in their current residence. Aging in place offers numerous social and financial benefits, and promotes keys to successful aging such as life satisfaction, health, and self-esteem.
A 星辰棋牌官网 describes factors that often prevent older adults from aging in place including auto-oriented land uses in their communities and a lack of access to transportation. Others who remain in their homes but are unable to make necessary renovations risk living with barriers that endanger their safety and limit their ability to participate in the community. Approximately 1.14 million older persons with health and mobility problems have unmet needs for additional supportive features in their dwelling units (Pynoos 2001). At this time, only age-restricted housing for elderly persons can usually accommodate the health and social challenges typically associated with aging.
To remain in their own homes while aging, people need housing designs that can be adapted to wider range of health conditions than traditional designs allow. Encouraging housing producers to adopt universal design features is a key aspect of design for aging in place. This includes a no-step entry, bathrooms on an accessible floor level, potential for a sleeping space on an accessible level, good lighting, efficient space planning, and other features that reduce effort and accommodate short-term and chronic disabilities.

Sustainability: Sustainable products used in buildings need to be designed to be operable by people with limited function in order to comply with accessibility laws, but they also have to be usable for the broader population or they will not be effective in practice. Due to their novelty, they often present usability issues to end users. This can result in replacing the product and even abandoning the goal of sustainability. Acceptance of innovative sustainable products can be enhanced through universal design. Consider the example of a waterless urinal. Every men's restroom requires at least one lower urinal. Most waterless urinals are only designed for the higher, traditional position, which means that they may cause maintenance problems or even require an accessible, traditional water operated urinal to supplement the waterless unit. Some require special cleansers to protect the finish and special tools and procedures to change the trap. If not properly maintained, the urinal will cease to function, start emitting an odor, and anger building occupants and owners. Bad experiences like this can result in replacing the product and even abandoning the goal of sustainability.
Workplace:星辰棋牌官网 Universal design is a critical consideration when designing work place environments for several reasons: 21.3 million (nearly 65%) of American adults with disabilities that are of working-age (16–64 years old) live with a chronic conditions that inhibit their capacity to maintain employment (Waldrop & Stern, 2003); typically adults spend a significant time working, thus making work environments important spaces in daily life (Sanford, 2012). Good design of the workplace can help increase participation of people with disabilities in the workforce, and can help to ensure that fewer accommodations will be needed if an employee has a disability. Additionally, achieving the highest level of usability in the workplace environment increases overall task efficiency, productivity, employee morale, and general safety and also helps employers attract and keep a broad and diverse work force.
Common Workplace Features:
Public Spaces:星辰棋牌官网 Public spaces include facilities open to the public such as stores, restaurants, amusement parks, parks and other recreation facilities, street rights-of-way, and transportation systems. Public accommodations are a critical domain for universal design because they are the site of key participation activities, including engagement in civic affairs, employment, recreation, education, and community mobility.
Common Universal Design Features in Public Spaces:
Social Justice: Throughout the world, designers with a sense of social responsibility are concerned that good design, like many other resources of society, is a commodity that many cannot afford. Although initially focused on disability rights, universal design can focus on any civil rights issue because ultimately design for diversity is concerned with social justice for all. Thus, universal design should give attention to supporting access to housing, education, healthcare, transportation, and other resources in society for all those groups that have been excluded from full participation. Universal design is particularly appropriate in the context of design for low-income minority groups, which often have higher rates of disability than the general population.
