control system possible. The lighting

system in the RSF consumes less than

0.2 watts per square foot and accounts

for 6 percent of the total energy used by

the building. Rachel Fitzgerald of RNL

was the lighting designer of record for

the RSF, and Juliana Ruffalo of Illumina-

tion Systems teamed withWeifield to suc-

cessfully implement this design.

Setting the Course for the Future

Fast forward to 2014: Weifield is currently

designing a 120,000-sf office building that

will use an all-LED solution. This new office

building will easily achieve a watt density of

0.3 watts per sf. The new office building is not

designed to maximize daylight harvesting and

we do not have an elaborate lighting control

scheme – yet, we are achieving watt densities

very close to the watt density of the RSF. For

another project, we are considering a foot-wide

LED fabric to light the building corridors. LED

fixtures capable of producing 120 lumens per watt

are commercially available right now. According to

colleagues in the industry, LED light sources in research fa-

cilities are achieving 300 to 700 lumens per watt.

The speed of the LED evolution is breathtaking and, ap-

parently, has just begun. Our vision and understanding of

how a light fixture looks and operates is changing. This is

a wonderfully exciting time to be part of building lighting

design.

I can hardly wait to see how lighting will evolve in the

next 10 years!
