Owners of the 34-story Plaza Towers Hotel – Condo – Apartment complex in downtown Grand Rapids Michigan decided the second time around to do it correctly. They found out they could have a very high quality facility-automation system, a cost-effective installation, very aggressive energy management strategies and highly accurate energy sub-metering all in one system.

The TAC Vista system installed by Grand Valley Automation has provided the owner with a very cost effective and flexible Facility Automation System. This system manages a 200-hp variable pumping cooling tower water system, 285 ton chilled water system and a steam heating system for all of the main mechanical systems in the 34-story facility.

The TAC Vista Building Management software gives the building engineer immediate and easy to use information about the operation on their mechanical HVAC systems. They use color graphics, status reports, data logs, energy logs, alarms, and plot windows to tightly manage the systems and energy demands in all areas of this facility.

The TAC Vista facility management software manages all data collected to provide concise data log reports, energy sub metering reports, and instantaneous status reports of the facilities HVAC systems. Steam energy costs are calculated for each tenant and documented in a monthly report to the owners.
