CASE STUDY

Vitality was able to identify energy cost savings of over $50,000/year for salt lake community college.

Overview

After the implementation of a full-scale energy management system at the college, Vitality continued to monitor the energy consumption of the college through the Vitality platform. It quickly became apparent to Vitality, as well as to the college energy manager, that they had pre-existing peak demand issues.

Problem

VITALITY was able to demonstrate that the college’s “resting” Kilowatt peak demand was around 750 kw, yet the college was being billed at a peak demand of over 1,000 kw. Vitality continued to monitor the kw and quickly noticed that the peak demand was happening consistently every night at a very specific time.

Findings

After the college was unsuccessful at identifying the cause of the peak demand themselves, they hired Vitality to help identify the cause of the peak kw. By watching each sub meter carefully, Vitality was able to identify that the kw was coming from the main distribution panel of the campus, before hitting any of the sub-panels. This narrowed the search, and from there it was discovered that the installers of a city owned water tower had inadvertently connected their pumps to the load side of the college’s utility meter.

Programming & Commissioning

After the implementation of the energy meters during the construction phase. Vitality oversaw the programming and commissioning of the energy meters. The commissioning included verifying correct installation, placement and manufacturer guidelines for data accuracy. Vitality programmed all of the meters to communicate back to a central data acquisition server that would be pushing all the data back to the Vitality software platform.

Vitality is one of the easiest vendors that we have worked with. they just get things done.

DOLLAR SAVINGS FOUND

Solution

Using information provided through the Vitality platform, Vitality was able to identify the problem as well as offer a solution to the college for reducing their peak demand. The implementation of this solution would provide a net decrease of an estimated 200 kw/month. By reducing the peak demand to less than 1,000 kw/month, the college would also be able to change their utility rate schedule to a more favorable rate schedule.
