Can someone really elucidate what Johnson Controls actually deals with?

There’s demand for a new, innovative way to construct a smarter, more optimized and efficient building. And it’s vital to consider the role technology will play – at the outset and long-term.  
Taking a holistic view of the building’s systems, Johnson Controls will design and install technology to support  business objectives.  With Technology Contracting, they act as the single point of responsibility for the design, integration, installation and service of the building’s technology, creating an optimized infrastructure, while cutting installation, as well as lifecycle, costs.
