About ABI



ABI Advantage LLC

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, and their combined multiple certifications and licenses in those and related fields, ABI Advantage LLC (ABI) was born.

Articles to Empower Your Mind

Uncertainty is not always a bad thing.

"One of the most striking things we have seen is how the uncertainty can lead to decision paralysis, where organizations delay doing anything and thereby forego the financial benefits their operational data can provide."

In case you weren't sold yet, here are more reasons why on-going analytics and performance modeling made specific to a building and its surroundings and conditions are so important.

"With analytic software applied to everyday building operations, owners are using data to their advantage and realizing cost savings through improved energy management." - Kramer, H., Lin, G., Curtin, C., Crowe, E., and Granderson, J. Proving the Business Case for Building Analytics. Lawrence Berkeley National Laboratory, October 2020.
