Electrical Engineering

The O’Brien Atkins Electrical Department is committed to designing safe, efficient, and facilities-friendly electrical systems.  We take great pride in coordinating with both the project Architects and Mechanical Engineers, as well as other specialists, to provide our clients with a highly sustainable building that will meet or exceed model energy codes to the greatest extent possible.

Our distribution systems are designed to fully isolate HVAC, plug-equipment, and lighting loads for accurate metering and monitoring. We achieve this by designing the most energy efficient electrical systems possible coupled with low wattage, high performance lighting systems. Our engineering goals are to bring the greatest sustainability possible to the project and within our clients’ overall budget considerations.
