are expected to continue

One of the showpieces
of the new construction
and retrofit project was
the installation of the
Audacy wireless-energy-management and
lighting-control-system, manufactured by
Ideal Industries Inc., Sycamore, Ill.
“Wrigley Field was a challenging
environment of concrete, rebar and other
construction materials," said Nolan Bello,
business unit manager, Audacy. "We have
achieved uncompromised signal strength
and range, and it’s a positive proving
ground for [Audacy's] integrity."
Audacy features push-in wire
termination and proprietary, patent-
pending wireless technology that
extends the life of battery-powered
devices, such as sensors and
switches, to 25 years.
The system at Wrigley Field uses
only one repeater for the entire lighting-
control solution. The repeater is located
30 feet below ground level in the
The solution also includes one proxy
server that can be run off a laptop or PC,
two backbone, gateway controllers and
hundreds of sensor devices. The Audacy
system integrates with the building-automation system using BACnet internet-protocol interface communications.
Of particular import

All controls are administered

Ideal, the wireless system can
reduce lighting energy use by
up to 50 percent.

amount of time we were at the project was
about eight to 10 days, which is a further
testament of ease of deployment.”
In the next several years, the project
will include the additional installation of
Audacy sensors, control units, gateways
and reporting components into the team’s
facilities, retail spaces, entertainment clubs,
suites and new five-story office building.

> THERE ARE DANGEROUS JOBS, and there are
extremely dangerous jobs. Electrical line workers
are near the top of the list.
According to the Bureau of Labor Statistics,
electric line worker is No. 9 on the list of jobs
with the most fatalities per number of workers.
With 19. 2 fatalities per 100,000 workers, electric
line worker is just ahead of construction worker.
Loggers are No. 1, followed by fishermen, pilots,
roofers, garbage collectors, farmers, ironworkers
and truck drivers.
The Bureau’s Census of Fatal Occupational
Injuries (CFOI) reflects data for 2014, the most
recent year with available annual data. According
to the CFOI, the total number and the rate of
fatalities per worker has dropped steadily since
1994. However, 2014 marked a slight increase in
both measures from 2013.
When the data is broken down by major
industries, utilities also made the list, coming
in at No. 15. This list includes construction,
transportation, government, agriculture and
others. There were 17 occupational fatalities
in the utilities sector in 2014, at a rate of 1. 7 per
At the top of the list, the construction
industry experienced 899 fatalities at a rate of 9. 8
per 100,000 workers. Other industries had fewer
total fatalities, but considering these industries
had fewer workers, they suffered a higher rate
per 100,000. For example, agriculture, forestry,
fishing and hunting experienced a fatality rate
of 25. 6 per 100,000 workers, while mining
and extraction had a rate of 14.2 fatalities per
