REMOTE AUTOMATED ENERGY MANAGEMENT PROVED TO BE KEY

St. Michael Church is a small parish of 7600 square feet with three zones, located in upstate New York.

CHALLENGE

The Church had a significant problem with gas and electric utilities, impacting both heating and cooling. In 2009, the staff had been located to another location, miles away, and the building was not being occupied regularly. Programmable thermostats had been installed but staff members would often override the programming and then forget to set them back. This resulted in having the entire facility heated or cooled for extended periods of time when no one was present.

When special occasions arose, outside of the normal programming, it was complicated for the staff and volunteers to make changes. With the extended times needed to heat or cool the building before occupancy, special trips to the Church were often required to change the settings.

We were happy to be a test site for the DLC. The web interface made it simple for staff to understand what was happening at the church and monitor the heating system. We have saved a lot on heat!

SOLUTION

The Save Energy Systems Demand Limiting Controller (DLC) provided an intuitive interface that enabled the church to utilize automated, intelligent energy management with the ability to control and monitor the facility remotely. This allowed thermostat set points to be adjusted using temporary overrides in real time to prepare for events that were outside of the Church’s regular occupied/unoccupied schedule.

RESULTS

The retail cost of the DLC system for the Church installation was $3,300. As a beta site and non-profit organization, the Church received a discount on the system and equipment. The installation costs were absorbed through the volunteer work of a parishioner/electrician that offered to coordinate the installation.

After factoring in the variances in winter weather year over year (Heating Degree Days), the reduced savings from both gas and electricity usage resulted in…a dollar savings over six months of $2,340 which was 34% savings from 2010 to 2011 and provided a ROI target of less than one year!

These savings don’t include all the time or gas saved from using the remote access to control and monitor the new system and not having to travel back and forth to the church to manually adjust the thermostats.
