Building Background • Location: 1800 Johnson St. Baltimore, MD. • Architecture (Design and Functional Components): Five story, 170,000 square foot facility • Fourth: Multi-purpose center, computer classroom, office space, auditorium, and three formal lobbies • Third: Tenbroek Library and Research Center and classrooms • Second: 36 classrooms, office space, and archive storage • First: Parking garage with main lobby and foyer (Southern portion at street level with the northern portion below grade) • Lower level: Parking garage (below grade) with storage space
Building’s Function • Enablethe disseminate the latest teaching techniques to teachers of the blind. • Educateparents of blind children of the cutting edge technology upon which their children’s success hinges. • Informadults and older people losing vision the ease of learning Braille. • Fosterthe direction and growth of adaptive technologies through a dedicated incubator center, to develop new ways to utilize computer systems with speech and Braille.
Area of Study *Pic of 4th floor plan to be added* • Computer Classroom • Multi-purpose room • Founders Gallery and Lobby *not addressing outdoor space*
Topics of Discussion • Lighting Computer Classroom (2 options and cost comparison) • Emergency Power Redesign (electrical breadth) • Lighting Multi-purpose room • Acoustical study • Daylighting Study in Lobby and Atrium • Lighting Lobby and animation
Lighting Design Criteria for the Partially Sighted • Safety issues: Clearly define circulation and emergency egress patterns without using distracting patterns. • Eliminate Glare: Keep bright luminaires out of occupant’s field of view (direct and reflected) • Increased Illuminance: For certain disabilities, 2 to 3 times the recommended ambient level will be required for visual tasks. • Adaptation Sensitivity: Introduce changes in illuminance level in a slow, comfortable fashion. • Contrasts: Increase luminance ratios of near to far field objects without creating glare.
Emergency Power (redesign lighting plan of computer classroom)
Emergency Power (Comparison of costs, benefits of new layout, etc)
Daylighting Overview (Founder’s Gallery/ Lobby space) • Clear glazing • Clear glazing with shades • Diffuse glazing
Summary of Design Changes • Pendant vs. Recessed fixtures • Emergency Power Distribution • Acoustical changes • Glazing changes • Lighting Design Metaphor
