Design Mecca Overcomes AV HurdlesA complete renovation of an historic building leads to unique meeting space at AIA’s Kansas City offices.By Gerard Grivois

T he American Institute of

Architects, headquartered in

Washington, DC, was founded in

1857, and today has nearly 300 state and

local chapters in the U.S. and around the

world. The AIA strives to meet the needs

and interests of the nation’s architects and

the public they serve by developing public

awareness of the value of architecture

and the importance of good design. To

accomplish their goals, some AIA branch

offices provide meeting space and facilities

that can be used by members and others

in their local design communities.

The AIA Kansas chapter, chartered

in 1921, offered more than 50 programs

to its membership in 2009. While these

programs and services are key to their

mission, AIA management felt these efforts

were constrained by limited space at the

chapter’s former West 9th Street offices,

which had been its home for the past

20 years.

When the chapter moved its offices

last year, it chose an historic, renovated

1907 structure in the Crossroads District,

a former downtown industrial area.

Helix Architecture and Design of

Kansas City created striking interiors for

the 4,634 square foot space, and St. Louis,

MO-based Conference Technologies, Inc. –

CTI – contributed an innovative AV system

design that addressed the space’s inherent

AV challenges.

System Design RequirementsThe centerpiece of the new space is a 2,000

square foot first-floor meeting room, with

windows on two sides looking out on the

neighborhood. The room accommodates

60 people classroom style, 150 theater-style,

and even more for receptions. A typical

lunchtime education session attracts about

70 architects, so the chapter has space

to expand.

“We conceived this space as a ‘Think

Tank’ for collaboration between various

design professionals,” says Jeffrey Schutzler,

project leader at Helix Architecture. “The

intent was to provide a multi-purpose

room capable of hosting a wide range

of events, from board meetings, lectures,

lunch presentations, special events, and

design charrettes. The red flooring,

projection wall, and ceiling reach outward

to pull not only architects and designers

into the office, but also the public.”

AV ChallengesTypical of historic buildings built in the

early 1900s, the loft-style interior of the

space was not exactly designed for AV

technology. Exposed brick, concrete slab

floors, and 16-foot high ceilings with full

height windows created an environment

with many challenges for both acoustics

and visibility of projected images.

According to CTI sales consultant

Steve Martin, one of the main challenges

in designing an AV system for this room

was its use as a rental space. “Most of

the people who do presentations here

will use the AV system infrequently or

only once. So the controls had to be

extremely intuitive.” That was one of

the reasons Martin recommended using

Extron’s TLP 700MV TouchLink 7-inch wall

mount touchpanel.

“It’s really simple to use,” Martin says.

“Extron includes a seven-inch touchscreen

in the panel plus ten backlit buttons and

even a master volume control knob to put

everything at a user’s fingertips. They also

have a simplified configuration scheme,

making it affordable for customers who

might not otherwise be able to budget

for a touchpanel and its associated

programming expenses.”

The TLP 700MV is linked to an Extron

IPL 250 IP Link Ethernet control processor,

which enables monitoring and control of

all devices in the system, including all

sources and a unique mechanical curtain

and window shade system. The TLP 700MV

touchpanel is wall mounted next to a

6 by 9-foot Da-Lite projection screen at

the front of the room, directly behind a

movable lectern.

“I think this is my favorite part of the

room,” says Tiffany Shepherd, deputy

director of the AIA Kansas chapter. “It

makes it really easy not only for us to use

the AV system, but also for us to show

other people how to use it.”

Another challenge was the sheer variety

of meetings that would be held in the

new room.

Schutzler included lightweight,

motorized room dividing curtains from

MechoShade Systems to reconfigure the

room for different types and sizes of

meetings. “This is a big space,” notes AIA’s

Shepherd, “but if we’re having a small

meeting, we can drop one of these mesh

curtains to make the meeting feel a little

more intimate.” Schutzler put one curtain

about 15 feet from the front of the room,

and another about 18 feet beyond the first

one. Touching a button on the TLP 700MV

touchpanel activates a motor so that a

presenter can easily resize the space to

the size of the audience.

Since the first floor meeting space is

bordered on two sides by floor to ceiling

windows, daylight became an obvious

issue for the visibility of projected images.

Room darkening MechoShades were

installed in each window to address this

problem. Another touch on the TLP 700MV

activates the shades according to ambient

lighting conditions.

Dealing with Acoustics CTI also designed and installed a flexible

sound system for the AIA’s various functions

and events. At the heart of the audio system

are two Extron DMP 64 ProDSP Digital

Matrix Processors, which provide all signal

routing, mic mixing, and equalization for the

various room configurations. The DMP 64s

each control a separate zone. Zone one is

routed to an Extron XPA 2001-70V power

amplifier, which feeds ten Extron SI 26CT

ceiling mounted speakers. The second

zone is connected to another XPA 2001-70V

AiA’s Design Challenges and Solutions

rooM FEATUrE DESIGN CHALLENGE SoLUTIoN

1 Floor to ceiling

glass windows

Hard glass surfaces create excessive acoustic

reflections, which negatively affect speech

intelligibility. Also, during daylight hours,

excessive brightness creates a challenge for

projected images.

Use ceiling mount speakers with smooth, flat

frequency response and controlled dispersion

to minimize sound reflected from glass

surfaces. install window shade system to block

excessive sunlight, and link to control system

for room reconfiguration.

2 Sheet metal

ceiling panels

Metal surfaces present another surface for

acoustic reflections.

Carpet floor surfaces directly below speakers.

3 Limited space for

AV electronics

Limits options for thermal management of

rack electronics.

Use high efficiency electronics with low thermal

output and convection cooling.

4 Concrete slab floor Creates both acoustic benefits and challenges.

Slab floors can enhance low frequency

performance of speakers, but they also

present a highly reflective surface that affects

speech intelligibility.

Use speakers with smooth, flat frequency

response and controlled dispersion.

5 Constantly changing

event types and

presentation needs

All aspects of AV systems must be easily and

quickly re-configurable.

Use a control system designed for easy

re-configuration and use by a wide range of

non-technical end-users.

power amplifier, which feeds five more

SI 26CT speakers. Since aesthetics of the

interior space was understandably a high

priority, CTI was able to paint all speaker

grills on the SI 26CT speakers to match the

red Armstrong ceiling panels, which allowed

them to blend in with the ceiling. The

DMP 64s also tie into the curtaining system:

touch a button on the Extron touchpanel

to lower one of the MechoShade curtain

dividers, and it automatically activates only

those speakers appropriate for the space

being used.

Sources for the system include a

built-in PC, two laptop inputs, a DVD/VCR

combo, and four Shure SLX wireless

microphones. The laptops connect to an

Extron SW2 VGA DA2 A active switcher and

distribution amplifier, which sends a video

signal directly to the NEC NP3250W LCD

projector and audio to one of the DMP 64s

for audio processing.

With all of the hard surfaces of the

cement floors, windows, and steel ceiling,

acoustics in the space could have been a

nightmare. To address potential slapback

echoes from the concrete slab directly

below the speakers, a large part of the floor

was carpeted. Minimizing reflections and

their negative effect on speech intelligibility

requires using speakers with superior

flat frequency response and controlled

dispersion – which is one of the reasons

why CTI’s Martin chose the Extron SI Series

speakers. The SI 26CT speakers feature a

coaxially mounted 6.5-inch woofer and one-

inch pivoting dome tweeter, which allows

it to be aimed away from highly reflective

surfaces, like the AIA room’s large windows.

All electronics are installed in a Middle

Atlantic SRSR Series rotating slide-out

rack, located in an AV closet behind the

screen at the front of the room. The space

is small with limited ventilation; the closet

measures only about two feet wide. With

such space constraints, the Extron XPA

amplifiers proved to be a literal perfect fit.

Each amplifier occupies only one rack space,

and is only one-half rack width across. And,

since the amplifiers are convection cooled

and extremely efficient, there’s no need for

special ventilation and cooling systems.

AIA’s Shepherd says the new space is

crucial to the chapter’s goals of expanding

its membership and of reaching out to

form alliances with others in the design

and construction industries. “It’s a really

cool space,” adds Martin. “I think all

of the contractors worked extra hard to

give them the best possible result. It’s a

real showplace.”

TLP 700mV Touchpanel

The Extron TLP 700MV 7" Wall Mount

TouchLink Touchpanel is designed to

mount securely into a wall, lectern, or

other flat surface. its ten backlit buttons

provide expanded control capabilities so

that critical functions are easily accessible.
