Built to Order

From the ground up, the tenants of the David Braley Cardiac, Vascular, and Stroke Research Institute help envision the facility’s complex and sophisticated AV systems design.

In the atrium, a 7000-lumen Christie Digital LX700 projector projects to a custom 22’x14’ stretched-fabric screen for video overflow from the auditorium. Alternatively, this setup acts as another video space for the facility to pass information to passers-by.

The Atrium

In the atrium, a 22’x14’ custom, stretched-fabric screen acts as a projection screen for overflow from the auditorium and as another video space for the facility to pass information to passers-by. Initially, the team talked about going the traditional route and hanging a fixed screen from the ceiling or a motorized screen that would come out the ceiling, but both ideas didn’t work with the modern, all-glass design aesthetic. The custom screen blends with the clean lines of the atrium. When the screen isn’t in use, it looks like another architectural detail.

The projector is a 7000-lumen Christie LX700 that’s embedded between the bulkhead of the first and second floors. Duocom had specified a 15,000-lumen projector because of the flood of ambient light in the atrium, but budgetary considerations dictated the use of the lower-brightness model and Crestron-controllable shades that can close individual banks of shades, the shades behind the screen, or the shades all around the atrium for sunny days. There are wired and wireless versions of the Crestron controller, so a person presenting in the atrium could present anywhere without using the wall-mounted control panel.

Along with almost the same input capabilities as in the auditorium, there are overflow connection points should the facility bring in a press company for a big announcement, for example. The system allows the press company to plug in and record a feed from the matrix or to feed the matrix with a camera of its own.

For audio, Duocom installed two small Tannoy QFlex 8 line arrays. Because DBCVSRI is part of Hamilton Health’s network of hospitals, a dedicated AV services team can troubleshoot most system problems remotely through the Crestron XPanel control system instead of contracting these services through Duocom.

Yusuf and Weitz and their research teams are still in their infancy of envisioning the endless possibilities the AV design has brought forth. With the respect and favor the facility has garnered, Duocom was given the AV contract for another hospital in the Hamilton Health network.

Standardizing the Experience

With retro fits, integrators face putting in new systems that don’t provide the same experience and controls as the existing systems that are still in use. A new build provides integrators with the opportunity to standardize on the experience where ever possible so that there is an overarching experience and design architecture for the user and the AV services who have to troubleshoot issues. If occupants can walk into any room and already know how to operate the technology there, they’re not only more likely to use the technology but be more efficient as well. This was the thinking behind the other conference and boardroom spaces of the DBCVSRI. Although the first floor of the Cardiac, Vascular, and Stroke Research Institute is the crowning jewel, the other conferencing spaces provide some of the same experiences using similar if not the same technology that’s found in the auditorium, atrium, and hallway. In the five standard meeting rooms that occupy the other floors of the facility, Duocom put in 3800-lumen Christie projectors, a SmartBoard SB680, and a smaller Crestron C2N-FT-TPS4 control system that are identical to the versions used on the first floor. Having the same projector manufacturer continues the theme while the Crestron control panel allows the room to be put on the network grid so problems can be troubleshot remotely.

Although the standard board rooms are not large and not all necessarily demand the high light output of the LX380, Duocom designed the systems occupying these meeting rooms to fit the least common denominator. That delineating factor was ambient light. Some of the rooms have windows that make it necessary to have 4000 lumens.

“But what we did was we said we’re going to put the projector in and we’re going to make it the projector that you need for the brightest room and in all the other rooms,” Prashad says. “We’ll just set the projector to Eco mode [in the rooms that don’t need more light output] so it projects it at less lumens, doubling the lamp life for those rooms. Not only did we have the ability to standardize, which makes service easier and asset management easier because we only have to keep one spare bulb instead of one for each model. They stretch out the consumable costs.”
