• Plan of main spaces


Tank Gallery and Mezzanine

• Located at North of building• 8000 sq. ft.

Tank Gallery


Tank Gallery

• 35’ ceiling height• North wall consists of

polycarbonate panels and glazing

• No south windows• Design Concerns:

– Turret tank focal point of space

– High ceiling– Daylight


Tank Gallery

• Turret located inside conservation tank• Port holes allow visitors to view conservation process


Mezzanine

• Public walkway in Tank Gallery

• Overlooks turret tank

• Runs length of gallery

• Design concerns:– Surface of water-filled tank acts as mirror– Illuminate walkway without distracting from display


Design Goals

• Maintain water line concept• Integrate daylight• Highlight turret tank• Avoid veiling reflections on surface of tank• Highlight other artifacts


Space Criteria

• Power density allowance: 1.6W/ft2

• Objects on display– 300 lux horizontal– 50 lux vertical– 5:1 contrast of object to surrounding


Mezzanine

Cannot place luminaires in this location


Tank Gallery Design

• Avoid reflections on tank – Wash ceiling– Wash floor

• Integrate daylight– Reduce energy with use of photocells to dim

luminaires

Space Criteria

• Power density: 0.7 W/ft2

• Corridor– 100 lux horizontal– 30 lux vertical

• Viewing tank– Avoid veiling reflections


Mezzanine Design

• Goal:– Wash surface of walkway to

avoid distracting glares• Solution:

– Light walkway from sides– Surface mounted luminaires


Library/Office

• Windows facing north• Includes desks, bookshelves, and meeting table• 500 sq. ft. (approx. 29’x18’)

Library/Office


Tasks

• Library– Bookstacks– Reading

• Office– Individual workstations– Visual display terminals– Group meetings


Space Criteria

• Power density: 1.3 W/ft2• Library

– Study desks: 300 lux horizontal– Reading 6pt. font: 500 lux horizontal

• Office– 300 lux horizontal– 30 lux vertical on VDTs

• Luminance ratios:– Paper task and VDT: 3:1 or 1:3– Task and surroundings: 3:1 or 1:3– Task and remote surfaces: 10:1 or 1:10

Conservation Lab

• No windows• 750 sq. ft.• 13’ ceiling

Conservation Lab


Room Tasks

• Conservation work with microscopes

• Cleaning artifacts• Mixing chemicals to

create conservation fluids


Space Criteria

• Power density: 2.5 W/ft2

• Conservation area– 500 lux horizontal– 100 lux vertical

• Color rendering very important• Limited glare on artifacts• Large-area low-luminance source can help

show imperfections

Tables and Sinks


Conservation Lab Concept

• Ceiling Cove• High illuminance on center lab table



• Build in cove lighting at outer edge of room– Creates ceiling as large area source– Use fluorescent for good color rendering



• Direct/Indirect luminaires over main lab table– Limits glare on artifacts– Use fluorescent for good color rendering

Cove Lighting

Direct/Indirect Lighting


Front Façade

• North side of building• Covered by building canopy

Front Facade


Front Façade

• USS Monitor replica located in front of gallery building


Front Façade Goals

• Limit light pollution• Glow as a lantern

– Brighter in middle to give rounded appearance

Controls

• Photosensors to automatically dim or switch off luminaires due to daylight

• Control several zones in gallery, mezzanine, and front façade

• Occupancy sensors in library/office and conservation lab

• Manual override for special events
