About CinéBistro — Cobb Theatres
CinéBistro is the crown jewel of the Liberty Center, an upscale outdoor mall in Liberty Township, Ohio. A Cobb Movie Theatre experience, it offers an innovative dining and movie experience built specifically with the discerning movie-going and dining customer in mind.
With opening night only six days away, CinéBistro executive staff faced a very tight deadline to find a solar control solution for 10 floor-to-ceiling, south-facing windows. The windows, each measuring 9' × 30' (221 square feet per shade), allowed unacceptable levels of solar glare into the restaurant and bar space.
The solar control challenge
CinéBistro determined that without the proper solar control solution, the glare levels would cause an uncomfortable environment for theatre guests as well as cause large shadows that muted the facility's beautiful interior decor.
In the summer months, the uncovered windows would allow unacceptable heat levels which would drive up energy costs required to keep guests comfortable.
The solution
Illinois Window Shade Company designed a solar shade system that successfully manages the solar glare transmittance at CinéBistro, providing a motorized shade system that promotes a comfortable and energy efficient environment.
A total of 10 Motorized Shade Systems were installed in the restaurant space, equipped with a woven mesh shade and driven by Intelligent Line Technology (ILT 3 RS485) motors seated into 3.25-inch tubes mounted from extension brackets that prevent the fabric from rubbing against the aluminum mullions.
The motors are controlled using two 12-port hubs, one 5-port hub, one bus power and an 8-button Animeo IP switch, allowing upper, lower and mid limits per the customer.
The woven mesh shade thoroughly reflects solar heat, allowing internal building controls to more efficiently regulate temperature levels throughout the facility, while allowing a high level of natural light into the room and reducing dependence on artificial light.
Results
The solar shade solution at CinéBistro looks fantastic, is easy for staff to operate and produces measurable results with respect to the light and heat levels in the facility.
The fabric effectively reflects solar heat gain while maximizing available natural light. The ILT motorization allows staff to control the very large and out-of-reach shades with the touch of a remote control button, and the quiet motors let facility staff operate the shades without disrupting normal business operations.
