Mall Court Redesign

Shane A. Semple - 13 - 4/8/2005

Final Report

Design Concept: The main goals for the mall court are to provide a welcoming, public

space that seems natural while still accentuating Monet’s and the Cosmetology Lab. The basic design concept for the Mall Court has undergone several iterations that all led to the final design. The first design ideas were very simplistic, with general ambient light that flooded the entire space and did not accent any certain areas in the mall court. This gave the space a public feeling, but was unsuccessful in drawing attention to the two main points of interest in the space, Monet’s and the Cosmetology Lab. The second design used aim able downlights placed in the lower ceiling areas on the perimeter to provide general illumination, while halogen spots accented the signage. Tree lighting was provided in this design by metal halides floods that were to be placed both above and below the trees so that a very large amount of light would reach the trees and help them to grow indoors. While the space still had a public atmosphere, and the important points were being highlighted, the tree lighting seemed unnatural due to the light coming from above and below the trees on all sides. These problems led to this final design:

Unobtrusive Linear Fluorescent fixtures the length of the space that give a feeling of linearity and length while making the space feel public.

Ceramic Metal Halide spots to accentuate the signage and give Monet’s and the Cosmetology Lab distinction in the space. Linear Fluorescent Wall Washers to illuminate the trees from above, only on the south side. This helps give the space the “natural” feel that was desired by the overall school design theme.

Design Criteria and Goals: The following design criteria are taken from the IESNA handbook, as well as the ideas of the designer.

• Appearance of Space – Many People from the community will enter through this space

• Color Appearance and Contrast – CRI at least 80, Cool Colors

• Daylight Integration – Luminaires need to dim when not needed

• Points of Interest – People should be guided to store fronts

• At Least 20 fc for egress on floor • ASHRAE 90.1 Allowance: 1.8 W/sq. ft

– Goal Power Density: 1.0 W/sq. ft.
