YANMAR Energy Series Case Study: Pike Road School, AL

YANMAR VRF are perfect for historic buildings

Pike Road School is located in a 100-year-old registered historic building. YANMAR America Energy Systems had the unique challenge of introducing the cost-efficient and environment-conscious VRF system while preserving every bit of the building's history.

“The YANMAR system and the YANMAR team have met all of the requests during
the project, and the system has worked flawlessly since being
commissioned. YANMAR has been engaged in the project from
start to finish, providing a high level of customer support”
- Laura Penn, Volkert, Inc. (Construction Managers)

Project Overview

Pike Road School is located in a 100-year-old registered historic building. The building itself was originally used as a school for 53 years before closing, re-opening as a church, and then shift gears again to be used as a school for 275 students in 7th through 10th grade. The facility includes 28 classrooms, a science lab, assembly hall, administration area gymnasium. Installed equipment includes 7 outdoor units, 50 indoor fan coil units, Building Management System, controllers and remote monitoring.

Reason for Choosing YANMAR

The main reason the school system selected YANMAR’s Gas Engine Powered VRF system was due to the manufacturer’s ability to design the system into the building without modifying it. Since the school building is registered as a historic building, no modifications were allowed; YANMAR was able to use ductless units in the areas with low ceiling heights that would not allow for ductwork. In addition, the city wanted to reduce their electrical usage as installing an electric-driven HVAC system would have required large, costly electrical upgrades to the facility.

Finally, YANMAR was also able to develop a maintenance plan for the school system to ensure that the VRF system will be properly maintained on a regular basis for continued uptime and optimum performance.


- Total savings of more than $11,000 during a seven month
period in which the system accumulated 18,300 operation

- Average savings of more than $1,600 during both cooling and
heating mode months with a savings of more than $2,800 during
the coldest month of the year.

- Reduced electrical consumption for heating and cooling the
building by switching to a natural-gas driven YANMAR engine
instead of an electrical-based system.

- By using natural gas as an energy source, the building
produces lower amounts of harmful emissions than traditional
heating and cooling equipment.
