Johnson Controls International makes heating, ventilation and air conditioning equipment, building automation systems and fire safety products used in commercial and industrial buildings. Its HVAC and building automation products help commercial building owners and operators manage energy efficiency, climate control and building safety systems, an increasingly important focus as buildings seek to reduce energy consumption and operating costs. Johnson Controls has increasingly emphasized software and services alongside its traditional building equipment manufacturing, offering ongoing building management and energy efficiency consulting services layered on top of its hardware sales. The company's revenue is tied to commercial construction activity and building owners' spending on HVAC upgrades, energy efficiency retrofits and building automation systems across its global commercial and industrial customer base.
