functions requiring 60 footcandles to those that require only a few footcandles. Due to the high quantity of downlights, they were carefully placed in relation to the fins both in distance from, as well as height above, to avoid scalloping of light on the fins themselves and minimisation of their visual impact. The induction lamping addresses maintenance and sustainability goals by delivering 100,000 hour lamp life, while the halogen lamping addresses flexibility goals by allowing for lower light levels suitable for more intimate settings. Ceramic metal halide downlights in lowered soffits balance the illumination levels at the room perim- eter. As part of the renovation design led by LMN Architects and Karlsberger Architects, the once fully enclosed space was opened up floor-to-ceiling on the south wall, developing a visual connection to the heart of the city and introducing the benefit of natural light.


The colour changing motif is brought through into the prefunction area by inte- grating LED luminaires into jut-out details highlighting the grand feature wall. The controls allow for the synchronisation of the colour of light with the ballroom LED fixtures, creating an excitement and antici- pation as visitors approach the ballroom for what lies beyond, as well as a connectivity between the two spaces.


The ballroom’s renewal truly provides the ability for the expression of a wide variety of dynamic and transformative experiences and, as a result, the Battelle Grand is “the new place to be” according to the Columbus Dispatch, quickly becoming the venue of choice for major corporations and com- munity organisations alike. The distinctive illumination for this premiere facility has been awarded a 2011 Lumen West Award of Excellence and an IESNA Illumination Award of Merit. www.hlblighting.com
