Can I include the Elevators (Lift/Escalators) in EAC1 credit calculation using the whole building simulation method?
I was told by an Elevator supplier that Regenerative Converter in lift could be beneficial while targeting the LEED EAC1 credit due to below reasoning,
“Although the power generated during traction machine operation is usually dissipated as heat, the regenerative converter transmits the power back to the distribution transformer and feeds it into the electrical network in the building along with electricity from the power supply. Compared to the same type of elevator without a regenerative converter, this system provides an energy-saving effect of up to 35%.
And this could be one of the Energy optimisation strategies that could be included while running the whole building simulation method for LEED EAC1”
I would appreciate if someone could share some thoughts on this issue.
Thank you

Yes you can claim savings for elevators. Establish the baseline in your area based on standard industry practice for your building type in your area. You will need to make the case that the baseline is reasonable. Then claim savings from that baseline as an exceptional calculation.

Ameet,
We also have a project where we hope to get EAc1 credit for regenerative elevators. Where you successful in documenting the savings and do you have any advice for backup documentation?
