A Limited Liability Company based out of Maryland providing custom building optimization and energy efficiency solutions for commercial and industrial facilities.


For several years prior to starting their own company in 2014, Sherri and Leroy Simms realized there are a lot of holes in the commercial mechanical and electrical industries and started gathering the necessities to start their own business to help address these issues.   Together with their desire to help the environment, Sherri's background in probability, statistics, programming, business administration and management, and Leroy's over 15 years of field experience in HVAC and Building Automation Systems, performing energy calculations and audits, multiple certifications and licenses in those and related fields, ABI Advantage LLC (ABI) was born.

ABI focuses on providing unbiased, trustworthy, high-quality, custom-tailored solutions that bridge the industry gaps by looking at both the energy and operational perspectives.  Using a holistic approach and keeping the ever evolving Internet of Things (IoT) in mind, ABI designs solutions with the best combination of functionality, efficiency, environmental impact, comfort and ease of use for each facility.
