Using the RTU Comparison Calculator to Justify High-Efficiency Units

Using the RTU Comparison Calculator to Justify High-Efficiency Units

May 20, 2014
1:00 PM-2:00 PM EDT

Presenters: Michael Deru (National Renewable Energy Laboratory), Srinivas Katipamula (Pacific Northwest National Laboratory)

The Advanced RTU Campaign is working with the Pacific Northwest National Laboratory (PNNL) to update its RTU Comparison Calculator (RTUCC). Join this webinar to learn how contractors and building owners/managers can use the RTUCC to compare RTU options and justify high-efficiency units, and provide your opinion on how the RTUCC can be improved to help make your job easier. The RTUCC compares high-efficiency rooftop air conditioners to standard equipment in terms of life cycle cost. This web application provides an alternative to complicated building simulation models, while offering more detail than simplified estimating tools that are commonly available. While simplified tools are typically based on full-load efficiencies and full-load equivalent operating hours, the RTUCC accounts for local climate and partial-load, as well as full-load efficiencies. The Comparison Calculator assists decision-making regarding the purchase or replacement of packaged rooftop air conditioning equipment, by estimating a product┬┤s lifetime energy cost savings at various efficiency levels.
