Do recycling rooms need to be negatively pressurized to meet the requirements of Interior Cross-Contamination Prevention in LEED V4 now that recylcing rooms must include the collection of batteries

Hi,

How do you go about a renovation in a LEED Plaitnum building? Do you have to do a recertification or another process. Theay are renovating 1 floor and I'm not sure the approach I need to take

I'm working on a v4 project currently in CD design phase.

Can an ASHRAE Level II Audit conducted in 2014 qualify for usage for this credit?

This question is regarding the Energy and Atmosphere prerequisite Minimum Energy Performance and associated credit Optimize Energy Performance under the LEED v4 Interior Design and Construction rat

What is non-default daily use values of water usage? How do I estimate them. This is required to be uploaded for the LEED-online WEp1. Thank you in advance for your help

I am working on a project located on a University Campus.  The building usage/type is most closely related to a dormitory.

Is there a minimum % of  new floors, walls, ceilings, etc. for a major renovation of an existing building under NC-v4? We are trying to decide between O+M and NC for a major renovation.

What are going off of for the 20%? 20% Material Cost???
