The Lighting Control Innovation Award was created in 2011 as part of the Illuminating Engineering Society’s Illumination Awards program, which recognizes professionalism, ingenuity and originality in lighting design. LCA is proud to sponsor the Lighting Control Innovation Award, which recognizes projects that exemplify the effective use of lighting controls in nonresidential applications.
This month, we will explore the role that lighting controls play at the recently renovated Kirkwood Linn Hall in a Cedar Rapids, IA community college.

This multi-phase, 175,000-sq.ft. Community College Building was remodeled from 2010 to 2014 to improve the overall learning experience by upgrading HVAC, lighting and architectural finishes. High-quality lighting and energy efficiency were key to the project’s success.
Multiple learning environments use this facility, including Dentistry, Biology, Microbiology, Health Science, Nursing and a local radio station and television studio. These functions are supported by effective lighting and controls utilizing fluorescent and LED sources. The facility’s 0.85W/sq.ft. betters ASHRAE 90.1, 2007 by 34%.
A building-wide lighting control system integrates nearly all of the fixturesby use of addressable fluorescent ballasts. These fixtures are connected to a common low-voltage bus that sends information on ballast and lamp status to the system and also returns 010V control signals based on time of day, photocell inputs, occupancy and manual switches and controls.
Due to changing environments and frequent remodels, the facility also utilizes wireless occupancy sensors, daylight sensors and manual controls that can be moved easily and recommissioned when educational programs change from year to year.
A large skylight was installed in the commons to improve views and add light to an otherwise dark space daylighting control was utilized to reduce energy consumption throughout this area. In classrooms, an entry switch was located at the doorways, along with dimming switches at the teacher’s podium. A multiple zoned room included direct/indirect fixtures
for ambient and two zones of wall washing at the front allowing for simultaneous A/V and whiteboard presentations.
The lighting control system utilizes a graphical interface, allowing the facility manager to see the current state of the lighting system. Due to the facility’s large size, the manager can use the desk top interface to high end trim the overall facility to save additional energy above stated goals by reducing overall output incrementally.
