CASE STUDY:<br />
Electric Vehicle Charging<br />
Prairie Point is a 24-story condominium building at 1600<br />
S. Prairie Avenue in Chicago’s South Loop. Prairie Pointe<br />
Owners Association and First Service Residential wished to<br />
offer an economical electric vehicle charging (EVC) option<br />
to condominium owners that also own parking space with<br />
the building’s parking deck.<br />
Electrical capacity within the parking deck was<br />
limited, and electric distribution is metered<br />
by the utility and paid for by the association.<br />
The board contracted with AMS Mechanical<br />
Systems to build infrastructure that:<br />
• Would bill individual users for the<br />
electric vehicle charging, rather than the<br />
association.<br />
•<br />
• Could be expanded without a significant<br />
investment by the individual parking space/<br />
condo owner as an EVC space is desired.<br />
The Solutions<br />
The design team at AMS determined that<br />
electrical capacity was available in the<br />
building’s main electric room that is adjacent<br />
to the parking deck. The electrical distribution<br />
panel was unmetered and intended to have<br />
distributed electric utility meters provided at/<br />
near the point of use.<br />
In collaboration with ComEd, the design team<br />
developed a distribution system with pointof-use<br />
electric utility metering at each parking<br />
space where vehicle charging is provided.<br />
These utility meters are assigned to each<br />
parking space/condo owner, and utility billing<br />
is direct to the owner.<br />
An electrical distribution system was installed<br />
and includes two strategically located panel<br />
boards with capacity to provide up to 40 vehicle<br />
charging locations. When an owner requests<br />
vehicle charging for their parking space, it is<br />
relatively simple and economical to extend<br />
power to the owners parking space and install<br />
the meter/receptacle.<br />
