As a result of this course, you will be able to:

  • Explain a MGE commercial building utility bill including how demand charges are calculated.
  • Discuss cost-effective strategies for RTUs to reduce both utility demand charges and energy consumption.
  • Specify the RTU related requirements of the International Energy Conservation Code, the current code in Wisconsin.
  • Discuss technologies such as economizers, demand controlled ventilation, staged air volume and energy recovery ventilation.

Who should attend?
Small- to medium-sized business owners, retail/office managers responsible for heating and cooling costs, HVAC system designers, engineers and contractors, energy efficiency specialists, facility and sustainability managers and anyone interested in learning more about reducing utility charges with commercial rooftop units.

Packaged rooftop units are used in more than 50 percent of all commercial buildings. With a focus on small- to medium-sized businesses, we’ll investigate how much they cost to operate. For example, did you know 20-30 percent of your utility costs could be due to demand charges? We’ll discuss these charges in basic terms, as well as numerous strategies to reduce them. We’ll dive deep into energy saving opportunities for existing units and review programmable thermostats, economizers, ventilation, controls and more. In addition, we’ll explore the decision process used to determine whether RTUs should be repaired or replaced when they fail or proactively replaced before they fail.
