TH&A file



10.1 This meeting of the Building Committee was convened specifically to review lighting for the building. David Malman of Architectural Lighting Design presented the current design proposals.

10.2 Malman reviewed the lighting schemes for individual offices. On the third floor the central area offices have 10’-0" ceiling heights. The North and South wings have 8’-6" ceilings. The second floor offices have 8’-6" ceiling heights. Two similar lighting schemes are proposed:

* In offices with 10’-0" ceilings a linear fluorescent pendant fixture is proposed. The fixture will be 8’-0" long and will be placed centrally in each room, parallel to the long wall. The fixture is a direct/indirect fixture. A sample was demonstrated by the team.

* In offices with 8’-6" ceilings a recessed indirect fixture is
proposed. Malman showed a cut sheet and explained the fixture, which has a recessed reflector pan. The lamps are housed behind a perforated baffle which hangs just below the finished ceiling height. The size of each light is 2’ x 4’. Each office would have (2) fixtures.

Each of these schemes is considered to be of very similar quality.

10.3 Malman discussed switching options for the individual offices. The recessed fixtures have 2 lamps and can be switched either with one lamp or two lamps on in both fixtures or alternatively each fixture could be switched fully on or off, independent of the other. The committee selected the latter at Malman’s recommendation. The pendant fixtures have 2 uplight lamps and 1 downlight lamp. These will be switched to allow the up-light and down-light components to be controlled separately.

10.4 Stuart Kaplan asked about eye strain and glare issues. Malman explained that the indirect lights are the lowest glare option for lighting in the private offices. Every light has electronic ballasts, which result in no flicker or noise problems; magnetic ballasts can cause fatigue because of the noise levels associated with them. The lighting schemes offer a variety of different lighting options. Glare at the computer screens should also be less
of an issue because the size of the office and orientation of the computer screen are such that a reflected image of the light in the monitor is unlikely to be a problem. Each user will have different preferences for how their environment is lit.

10.5 The direct/indirect lighting scheme is by far the most energy efficient lighting scheme compared with a conventional lighting approach, requiring less watts and fewer fixtures to achieve the desired light levels. Among direct/indirect fixtures the selected product is in the middle range of energy efficiency.

10.6 The committee approved the office lighting schemes.

10.7 The central open office area on the third floor was reviewed. The general lighting approach is a long indirect fixture pendant-hung at approximately 13’ to 14’ above the finished floor. Light will be reflected off of the vaulted ceiling. The fixture has small openings that allow light to be seen from below so that the users can "see" that the light is turned on. Wall mounted lights will be used at the project areas to provide a large scale version of task lighting at these locations.

10.8 The north and south open office wings were reviewed. The meet/study and work areas in these locations were planned to be lit via recessed direct fixtures, 6’-0" in length. Campus Planning and facilities urged the team to consider 4’-0" length lamps. This will be reviewed and implemented if possible. The circulation areas in the wings will be lit with a combination of recessed
downlights and wall-washers.

10.9 As a separate study the team is considering additional energy saving options. These might include such things as reducing the ambient light provided in each office and adding task lighting. Once the proposals are identified they will be priced and subjected to a "life cycle cost analysis" to determine if the value that they offer is worthwhile.

10.10 Malman presented the lighting concept for the public corridors, which include a mixture of indirect lights illumination the ceiling and downlights at the classroom entrances. The effect should give rhythm and variety to the experience of the corridor.
