Value Delivered
ECM worked with Schneider Electric to develop and deliver an HVAC refurbishment solution for Jackson County Schools, aimed at increasing the efficiency of rooftop units that were not yet ready for replacement.
During measurement and verification, we calculated the project will save 620,910 kilowatt hours a year, valued at $67,741. This was nearly twice our initial projection. Additional savings from reduced maintenance and equipment life extension are also expected. Simple payback for the project is four years.
Client Objectives
The client wanted to extend the useful life of existing HVAC units across their school district and improve energy efficiency.
Solutions
Our team rejuvenated coils on 600 rooftop units at 20 school sites. Our work included:
- Cleaning each unit and pressure washing coils
- Capturing operating data to validate pre- and post-project performance
- Disassembling equipment and performing deep clean
- Straightening aluminum fins to increase airflow
- Completing an endoscope for each coil (pre- and post-project)
- Applying HVAC Armor coating to condenser and evaporator coils
- Measurement and verification, including enthalpy testing, to calculate and validate energy savings
Client Background
Located in northeastern Alabama, Jackson County School District enrolls approximately 5,150 students.
