Drive down consumption with variable frequency drives on air handling unit fans
Your local utility may offer up to $300 per horsepower for qualifying variable frequency drives (VFD) on air handling unit (AHU) fan installations. Adding a VFD on a constant speed AHU fan allows the drive to match the amount of energy the motor needs for the amount of work that is being done. As the fan slows down, it draws less power than at constant speed, resulting in energy savings. This allows…

Advanced Rooftop Controllers Tool
Local utilities are providing retrofit incentives for Advanced Rooftop Controllers (ARC) and Air NW has a new tool to help drive the sales.
ARCs are applied to single zone rooftop systems with constant speed fans to modulate the fan speed. Most commercial buildings are over-ventilated because the constant speed fans are set to run when the building is supposed to be occupied regardless…

What About ARC?
What do you do when you encounter a rooftop unit (RTU) that is wasting energy but not yet at the end of its life cycle? Do you replace the RTU with a new one or do you explore other energy efficient options, such as a controls? In this post we will discuss that second option, controls, specifically Advanced Rooftop Unit Controls (ARC).
