In the past couple of years I have had many opportunities to work with building owners and property managers on their HVAC systems. One subject that comes up frequently is dissatisfaction with the quality of work done by their service contractor. I have been called in by some of these people and asked to price a maintenance agreement.
The building manager then asks, "Can you also include the EMS (energy management system) in your price?" I look at the system, and often the answer is no.
