Objective

The team utilized Fluke Connect enabled tools to measure a commercial facility’s energy usage and performed an energy audit based on the ASHRAE guidelines. After analyzing the data collected, recommendations are to be made in order to reduce operational costs, maximize ROI, and improve reliability.

To improve the audit efficiency, the Fluke connect app was leveraged to streamline and organize energy data collection. The data collected was paired with an individual piece of equipment or panel within the Fluke Connect app’s equipment database. At completion of the audit the database was robust enough to be turned over to the facilities manager as a resource to help in the management future maintenance activities.

Methodology

Conduct Preliminary Energy Analysis (PEA)• Compile Energy Billing Data• Calculate Energy Use Intensity (EUI) • Compare Building to other Buildings in Energy Star Portfolio

Conduct walk-through survey Identify low Identify low-cost/no cost/no-cost recommendations Review Construction Drawings and Schedules Measure key parameters with Fluke Connect enabled tools Analyze capital measures (savings & costs including interaction) (In Progress) Meet with owner/operators to review recommendations (In Progress) Submit final report on findings and equipment database (In Progress)

Results – Panel Monitoring

The energy analysis utilized current and voltage meters to log data over the period of the energy audit at the first panel boards P1A, P1B, and P1C as seen in the one line diagram. The meters were left on site to collect the data for 3 days. This data was used to calculate energy consumption to discover what times of day certain areas of the building are operating inefficiently.

IR CAMERA USES Visually Identify Energy Losses Detect missing insulation in ceiling tiles Detect air leaks Detect moisture and leaking pipes Locate thermal bridges Locate water infiltration Identify high resistance electrical connections Identify abnormal electrical conditions

When applying the A3001 current monitors to the individual panel feeders, IR scans of the panel boards were captured while the panels were exposed.

Ceilings were scanned to identify locations where insulation had been moved and not replaced. Air leakage and moisture was monitored.

Results – Equipment Logging

Using the Fluke Connect app to manage the equipment logging offers these benefits among others:

Easy access to update information in the log at any time

Convenient and stress-free to use even when access is needed at the work site

Ability to have pictures and data stored together in a user-friendly manner makes for more productive use of time

Impact & Recommendations

How did your project make a difference?Our project made a difference by creating a framework of how to incorporate fluke connect tools in an energy audit in order to streamline data measuring and communication between coworkers. In addition it proved how simple and effective an energy audit can be when using the fluke connect tools for data measuring and communication.

Would you recommend that others apply your process? If so, what specific advice would you give them?

The Fluke app along with the wireless tools and data logging were extremely beneficial to the project. They enabled our team to be able to review large amounts of data in a short amount of time. The advice our team would give to others trying to connect an energy audit would be to take advantage of the data logging at different panels over the same time period. The Fluke tools allow for time stamped data which can be used to show a causal relationship between energy inefficiencies and their root cause.

Lessons learned

• The Fluke Connect tool is a great way to organize a facilities equipment into one database that can be easily accessed by anyone with a smart phone.

• The app supports the audit process by allowing a vast amount of data to be easily associated with a particular piece of equipment or panel. 

• After the audit, the database can be used by facility maintenance personnel to view equipment nameplates, field existing panel schedules, and past data that can be compared with real time measurements.
