Building Preview

The von Liebig Center for Science is an 88,230 square foot, 20 million dollar science facility located at Juniata College. Its classic brick facade and look fits perfectly within the historic campus architecture. Vast floor to floor heights combined with

large common spaces produces an openness that promotes interaction and socializing between the biology and chemistry

departments.

Spaces to be Redesigned

• Chemical Synthesis Lab• Lecture Hall

• Seminar Room• Front Elevation

Chemical Synthesis Lab

Characteristics • Lab benches are located in the main floor area. • Windows make up the wall.• The remaining three walls are composed of fume hoods.• Dimensions: 43’ x 27’

Goals • Reduce power density• Sustain an adequate light level on task planes.

Lecture Hall

Characteristics • The ceiling is composed of a 2’x2’ grid incorporated into

an architectural pattern.• The wall is composed of windows.• A series of white dry erase boards and a projector

screen is located at the front.• Dimensions: 56’x47’

Goals • Reduce power density• Sustain an adequate light level on task planes.• Provide an even flow of light on the white dry erase

boards.

Currently only two spot lights and four down lights shine upon the white boards.

Replacing the current system with a spotlight aimed at each of the sections below will create an even flow of light.

Downlights

• The current downlights utilized are 150W incandescent. This can get costly when considering there are 70+ downlights within the lecture hall. Replacing these with a 50W compact fluorescent will drastically reduce the power density; yet still maintain a high illuminance level upon the desks.

Front Elevation

Characteristics

Goals

The architecture of the building is a rather simple brick face with asphalt shingles. Glass fiber reinforced columns compose the front main entryway. The windows and doors are aluminum

and glass with a cast stone surrounding. A staircase on the side of the building utilizes a split-faced ashlar stone surface with a

cast stone coping.

• Light the façade in a respectable non flashy manor.

Current Conditions

Lamp posts are along the walkways leading to the science center

Six inch down lights are located over the main entry area.

The existing fixtures will remain. Yet improvements can be madeA flush mounted up light will be placed in front of each of the four pillars.

The rest of the building will be lit via wide floods.
