Weekend Warriors to World-Class pus amenity. Lighting for this facility needs to address the wide range of uses housed in the same facility and wrap them all up in an energized, upscale look. Before any lighting for the interior was considered, an inviting exterior presence had to be established for the center that worked both day and night. Working closely with Hughes Group Architects, Horton Lees Brogden (HLB) designed lighting that would make sure the multiple views into the building became glowing advertisements at night that beckon the passerby to enter and explore. Large-scale pendant lanterns at the main entrance and limited exterior building lighting proved to be an effective and economical solution that gives the building form. Full Workout Meanwhile, the project scope for the interior encompassed everything you would expect to find in this new generation of recreational centers, including: Natatorium. The natatorium houses an Olympic-size pool with a 10-meter diving tower and spectator stands. Activities range from general recreational and instructional to full-blown NCAA competition. Along with the given lighting requirements for safety, corrosion resistance and incumbent lighting levels comes the need to add a little more “zip” to the natatorium during competitions. While the university was not interested in NBA-style spot-lighted player intros, HLB was able to provide a bit more “focus” on the pool and the swimmers by utilizing narrow distribution fixtures that pump the 500 lux of general/recreational lighting up to a tightly controlled 1000 lux on the pool alone. Two 400-W pulse-start metal halide fixtures with two different lighting distributions were attached to the roof trusses and are serviced from a gantry that spans the natatorium. Four preset scenes were achieved with careful circuiting and low-voltage relay switching. Diving Tower. Two considerations must be met when lighting a diving tower. The diver must be able to see the surface of the water and the spectator has to see the diver. The speed at which this all happens adds an extra burden to the visual system and thus the lighting. Comprehensive studies were performed to ensure that the vertical illumination from the top of the diver’s trajectory to the water surface were uniform, of a high level (1000 lux) and did not create disability glare for the diver (particularly at the platform level). The vertical illumination was achieved through 150-W metal halide flood- Athletes LIGHTING DESIGN AT THE NEW UNIVERSITY OF HOUSTON RECREATION CENTER ACCOMMODATES ATHLETES OF ALL STRIPES The gym is no longer the sole domain of the jock. In fact, the gym isn’t just the gym anymore. It has become the athletic center. Along with the essential natatorium, gymnasium and weight room come leisure pools, climbing walls, water slides, a sea of exercise equipment and even the spa. The user base has logically expanded from the hard-core athlete to include everyone from the simply health-conscious to those just looking to relax and maybe find their next date. At 264,000 sq ft, the University of Houston’s new Campus Recreation and Wellness Center is the epitome of the new cam- Safety, corrosion resistance, proper lighting levels and even the need to add some spark to NCAA swimming competitions drove the lighting design of the natatorium.

Lighting of the diver’s path close to the water surface added the extra levels needed at the surface (in combination with a water sprayer that creates surface turbulence). Multi-Purpose Gymnasium. While traditional gymnasiums were typically lighted with 400-W pulse-start metal halide high-bay fixtures, the multi-purpose gymnasium needed more attention because of its diverse uses. In both the traditional and multi-use gymnasium (as well as the natatorium), lighting designers recommended that the ceilings and ceiling elements (acoustical panels, ducts, etc.) be of a high reflectance value to promote visual comfort and reduce brightness contrast between the fixtures and the ceiling beyond. In the multi-purpose gymnasium the nearly white ceiling provided an opportunity for uplighting to create the lower, soft ambient lighting levels required for non-athletic uses. Asymmetric fluorescent uplights were located on the lower flange of the trusses and circuited to provide three levels of lighting (200/300/500 lux) through switching. Exercise Equipment Area. No matter how you try to work it, you always end up sweating on your back in the exercise area. To minimize the pain of exercise, HLB utilized pendant-hung linear fluorescent uplights to provide comfortable general illumination no matter which way the user was facing and just enough small accent lights to highlight the sparkle of the hightech exercise equipment in an effort to reinforce the dynamic nature of the space. Rock-Climbing Wall. The big enticement to visit the athletic center is a view of the rockclimbing wall as you enter the facility. It is seen just beyond the check-in desk on the opposite side of the palm tree-filled rotunda with its jumbo video screen. The climbing wall clearly had to stand out amid all this visual competition. The right lighting to create this visual focus and to provide a user-friendly, safe experience was key. PAR38 metal halide fixtures were located at the ceiling level and at various PHOTO: TIMOTHY HURSLEY At the rock-climbing wall, the angle of the lighting was critical to dramatize the craggy texture of the wall, but without creating disability glare. The ceiling in the multi-purpose gym has a high reflectance value to promote visual comfort and reduce brightness contrast between the fixtures and the ceiling beyond.
