to poor lighting. As a person ages, according to Herman Miller (2001), changes that occur in the
eyes as a result of aging lead to decreased light transmission and color identification.
Many professionals who work with building design and with occupational health issues
recommend ergonomic lighting, as one of the best measures of creating a more comfortable
workplace. The National Institute of Building Sciences (2009) recommends that businesses
provide as much natural light as possible, while avoiding heat gain or loss and glare, make
individual task lighting available and adjustable and light vertical surfaces, such as walls, to
increase perceived brightness. The U.S. General Services Administration (GSA) also uses and
recommends the use of ergonomic task lighting that is adjustable, for individual work spaces,
as a part of its overall world class work space program (2005).
The major concern in providing adequate lighting is energy costs. The question is
whether ergonomic lighting can be energy efficient and even help lower ...
