Johnson Controls developed the LEAN energy analysis technology over the past eight years and has used the tool to analyze retrofit opportunities in over 700 buildings. Berkeley Lab is working with Johnson Controls to automate and improve the LEAN energy analysis tool and create an open-source version of the tool for public use.

According to the AEA, nonresidential buildings consume more than half the building energy use in Alaska, and the majority of these buildings are privately owned. The Commercial Building Energy Audit program is designed to pay up to 75 percent of the cost of an ASHRAE level 1+ energy audit performed on privately owned commercial buildings.

As architects and engineers draw up plans for commercial buildings, it is a common practice to design openings in walls. In many cases, these openings allow for intake and/or exhaust air that supports the building’s HVAC system and are fire-resistive rated.

Verasys™ is a plug-and-play solution that integrates HVACR equipment and controls. Designed for light commercial buildings, this controls system provides a simple user experience with configurable controllers that seamlessly connect to a wide array of mechanical and electrical equipment, controls, and sensors, without requiring any special programming tools.
