Case Study - Sacred Heart School

This school in a 100 year old building wanted to add air conditioning. Like other contractors, Althoff Industries provided a quote for a VRF system.

Unlike other contractors, Althoff Industries said that the work could be completed in a single summer instead of being a multi-year project. The job was completed during summer break on time and on budget.

Case Study - 2 N Riverside

Althoff Industries was able to value engineer an upgrade of their building control system by integrating their legacy system with our open protocol Tridium AX control platform.

This gave them real time 24/7 monitoring and text/email notification capability without having to rip out and replace the entire existing system.
