Lighting Design & Perception

As architects an4215_78395969420_5693135_nd designers, we are tasked with creating functional spaces.  The primary focus is on the tangible, built form of walls, floors, and enclosures.  This is a necessary beginning, but much more can be incorporated into the design of the space.  Lighting is an important element in design, not only from a functional point of view, but also from an experiential perspective.  The same space can be perceived in many different ways, simply by using lighting to change the perception of the static built environment.

As a stage performer (and an architect), I have the opportunity to witness the affects of various lighting techniques in the theater.  The dramatic changes that can be made to a simple stage space using different colors, different focus, and different amounts of light can be a source of inspiration for the way we light our everyday spaces.

The use of “luminous ceilings” and the high level of general lighting that has been prevalent in office design can have a numbing, uninspiring effect on the users of the space.  Simply providing some variety, such as the use of lower ambient lighting combined with task lighting at work spaces and accent lighting in the common areas, can help make the space more interesting and keep users energized.

The combination of new energy use codes and new types of light sources has given architects a wider variety of options to use in lighting spaces.  Smaller, more efficient luminaires combined with new fixture designs to house them provide a better quality of light in the space, as well as visual interest in the lighting instruments themselves. The ability to precisely control the output of light sources and to change the intensity and color provides the opportunity to create stage-set lighting effects in the everyday world.  Putting the right amount of light in the right location also helps to make spaces more functional as a result of bringing focus to the area desired without distraction from surrounding areas. For example, using special highlighting in a museum gallery to accent a particular exhibit helps to make it a destination as visitors are approaching the space through a background lit corridor.  Lighting controls can also aid in varying the lighting schemes, as it is possible to create and store different scenes , making it easier to adjust the entire lighting palette, much as it is done in the theater.

Are You “Wimpy” When it Comes to ADA Compliance?

Wellington Wimpy was a character in the long running comic strip Popeye. For those of us old enough to remember the Popeye cartoons, you will recall that Wimpy, as he was known, was famous for the line “I will gladly pay you Tuesday for a hamburger today.” For some commercial building owners, this phrase may apply to them relating to ADA (Americans with Disabilities Act) compliance in their buildings.

For the uninitiated or new building owners who may not fully understand what the ADA is, here is some background.  President George H. W. Bush signed the legislation in 1990 designating it “the world’s first comprehensive declaration of equality for people with disabilities.”  The 1991 ADA Accessibility Guidelines (ADAAG) set the standard for what makes a facility accessible and the law became effective in 1992.  The ADAAG requires businesses to remove architectural barriers in existing buildings and to ensure that new construction and alterations are built to be accessible to individuals with disabilities.

What does that mean to you as a business owner?  Immediately upon implementation of the ADA in 1992, all business facilities (common areas and tenant spaces) were required to remove architectural barriers as soon as it became “readily achievable” to do so.  Readily achievable is defined as “easily accomplishable without much difficulty or expense.”  Unfortunately, what is considered “easily accomplishable” is not specifically defined, but parameters have been set over time by federal court rulings.  Because of the ambiguity in the law initially, many business owners decided to wait.  They thought it was enough to provide an alternate solution (such as providing curbside assistance or directing people to a secondary entrance) or they waited until a major renovation was necessary.  Unfortunately, neither approach could stop someone from filing a lawsuit which could become much more expensive than fixing the problem in the first place.  Taking a proactive approach and addressing what you can as soon as you can, will save you money in the long run rather than gambling on a lawsuit.

The courts have provided guidance by setting priorities for readily achievable barrier removal – starting with the path of travel from parking lots & public sidewalks to building entrances, then moving on to restroom & water fountain accessibility, and so on as you make your way through the facility.

The ADAAG, which is the basis the courts use to determine compliance with the law, provides text with diagrams showing its intent.  Many people familiar with the ADAAG consider it to be similar to a building code.  It is very important to note that the ADAAG is NOT a code.  Building codes are constantly evolving with revisions that are published on three year cycles.  Unlike building codes, the ADAAG remained unchanged from 1992 until 2010 when the U.S. Department of Justice adopted new standards.  Since the adoption of the ADA, many of the building code organizations, recognizing the challenges of enforcing standards that they had no control over, incorporated accessibility criteria into their documents that could be enforced.  Consequently, the 2010 ADAAG sought to harmonize the standards with the building codes and other industry guidelines.  However, the 2010 ADAAG is still NOT a code and can only be enforced through the federal court system by federal judges.

It is also important to note that “grandfather provisions” typically found in building codes do not apply to ADA compliance for businesses or building owners.  All buildings are required to be ADA compliant; however, a “safe harbor” does exist for buildings that currently comply with the 1991 ADAAG.  All elements that are currently in compliance with the 1991 standards are still considered compliant even if they do not meet the 2010 standards.

However, there are circumstances where this may not be true.  If you plan on making modifications to primary function areas within the building, you must also consider the path of travel to those areas.  If the path of travel was compliant with the 1991 ADAAG, but is not in compliance with the 2010 version, you must upgrade those areas as well.

These days it is easy to comply with the ADA if you are building a new facility.  It becomes more complicated when the building predates the issuance of the ADAAG.  For buildings that predate 2010, it is a good idea to have a full evaluation of ADA compliance.  The evaluation should identify compliance with each version of ADAAG and contain a plan to remedy non-compliance issues.

The bottom line is that ADA compliance can be very complicated in a single use facility.  But it gets even more complicated when you introduce multiple tenants or mixed uses into a facility.  Well intentioned modifications made by businesses or building owners without the guidance of professionals who work with the guidelines regularly can come back to bite you.  Just like the bite that Wimpy takes from the burger he promised to pay for next Tuesday.  Hoping to put off expenses for alterations to business facilities in the hope that you will never be sued can make that hamburger very expensive and hard to swallow!
