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.
Design Team
- Owner: Juniata College - Civil Engineer: Keller Engineers

- Lab Consultant: Research Facilities Design
- Architect: Hastings & Chivetta Architects, Inc.
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.

1632W/1161ft2 = 1.4W/ft2
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.
Current Power Density4.27 W/ft2
Projected Marker Board: (8)(100W) = 800WDownlight: (75)(50W) = 3750W
4550W/2632ft2 = 1.73W/ft2
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.
