Manufacturers were eager to show off their latest energy-efficient RTUs, many of which can also be used to meet building owners’ decarbonization and electrification goals.

While new DOE standards drive innovation and opportunity within the HVAC industry, they also add pressure and complexity for manufacturers.

The ACHR NEWS caught up with Johnson Controls’ “Game On” Roadshow at its final stop in Rochester Hills, Michigan.

For many manufacturers, higher efficiency systems have been in the works for a while, but the 2023 DOE standards, pandemic, and current supply chain issues have added pressure.

Commercial rooftop units feature a host of intelligent solutions to improve efficiency and ease of service/installation.

With each passing year, rooftop system developers find new ways to improve this staple piece of HVAC commercial equipment.

The 27.5- to 50-ton rooftop units exceed Department of Energy energy efficiency standards, reducing operational costs over the lifetime of the unit.

These products are designed to serve both the new construction and replacement markets.

The first phase took effect on January 1, 2018, and increased the minimum efficiency of commercial rooftop units (RTUs) by about 13 percent.

This features simple fan setup and service with a new intuitive control board, and a beltless direct-drive vane axial indoor fan system.
