Hello everybody,

We are working on a project under LEED V4 certification.

ABOUT PREREQUISITE “MINIMUM ENERGY PERFORMANCE” , we must comply with the ASHRAE mandatory provisions and therefore comply with the VOLTAGE DROP of section 8.4 of ASHRAE 90.1 - 2010. In our case, we will apply the proposed alternative compliance path for meeting the mandatory requirement of ASHRAE 90.1-2010 Section 8.4, Voltage Drop Limitation of the following addendum:


But we don't understand what the ADDENDA means by: "from service entrance to the worst-case connection"?

Does that mean respect the drop voltage from the electrical panel to the sockets? from the final circuit breaker to the outlet? Or other?

Many thanks,
