RTU Retrofit reducing HVAC energy usage by 25-50%
Are you looking for ways to save energy and to save on operational costs in your building? Transformative Wave’s CATALYST could be your answer.
Constant volume rooftop units consume a lot of energy to keep your building comfortable and healthy for your occupants. But what if you could produce the same level of comfort while improving your system’s performance and lowering energy usage by 25-50%? That is exactly what the CATALYST does.
The CATALYST is a complete HVAC energy efficiency upgrade for your currently installed RTUs. This retrofit combines the benefits of a supply-fan speed control, demand controlled ventilation (DCV), and additional sensors to provide optimal energy savings. The CATALYST can be monitored and controlled in real-time through a wireless, web based eIQ Energy Intelligence Platform, which tracks energy savings and system behavior.
Benefits of the CATALYST
The CATALYST reduces operation costs, maintenance costs, and replacement expenses by:
- Lowering HVAC energy usage by 25-50%.
- Maximizing the use of outside air for free cooling beyond standard economizer logic.
- Reducing fan energy use by an average of 69%.
- Reducing wear and tear on the fan motors, belts, and pulleys by providing softstart capability.
- Reducing compressor runtimes with improved economizer control strategies, increasing equipment life spans.
- Monitoring for proper operation and internal fault detection to protect the equipment.
- Never compromising comfort, indoor air quality, or the integrity of the equipment.
Tested and proven
The CATALYST was the subject of a two-year study commissioned by the U.S. Department of Energy through the Pacific Northwest National Laboratories (PNNL). The CATALYST was installed on 66 existing RTUs in four different climate zones and varying building types. The field trials of CATALYST resulted in an average HVAC energy savings of 57%.

The CATALYST has been installed on other RTUs throughout the country with comparable success. The CATALYST has received backing from utility companies across the country. Transformative Wave is also a contributor to the Advanced RTU Campaign, organized by ASHRAE, Retail Industry Leaders Association (RILA), and the DOE, who have all agreed that the CATALYST is a viable alternative RTU replacement as a means to save energy.

Machines run smoother when they are maintained. A preventative maintenance plan means lower operational costs (as much as 50% compared to reactive maintenance) and a more efficient HVAC system, which means lower energy bills (as much as 20%).See more tips
