Everyone will experience physical challenges at some point in life - through illness, physical injury or limitations of old age. Universal design takes a preventive, pro-active approach, accommodating an individual's changing wellness so they can remain functional and independent in their own home. It focuses on providing a living space where people of different capabilities can live in a household at the same time. A residence that incorporates universal design so it is flexible for all occupants of the space and maintains its usefulness as circumstances change for its occupants, reducing the need to relocate, is inherently more sustainable.
Energy efficiency and a healthy indoor environment are major components of good universal design: encompassing water conservation, non-toxic building materials, air quality, elimination of allergens and focusing on how the light, thermal comfort, acoustics and noise generation affect the quality of the space. In addition, using the best products and materials that can be afforded and will last the longest will have the least long-term impact on the environment.
For example, a kitchen that incorporates universal and sustainable design would be easily accessible from all adjacent areas, including wheelchair access. It would maximize the efficient use of space, light and fresh air. Appliances would be quiet and energy/water efficient. Upper wall cabinets could be located at a lower height and include open front shelves. Counter tops would be wheel chair accessible.
When a living space is energy efficient, healthy, and can be used equally by all occupants, good sustainable and universal design has been achieved.
