Hi, I was wondering if the v2.2 option (HERS methodology) would still apply for v2009 in regards to the blower door test and number of units that must be tested.

We are working on a large high-end high-rise residential project with a variety of unit sizes and layouts.

Hello Everyone, We are currently working on a project that requires LEED certification. In this regards, I am soliciting everyone's support to share me your expertise on LEED.

For Mid-rise residential buildings it is required to perform a blower door test according E779-03 but international ASTM web site indicates that this standard has been superseded by ASTM E779-10.

I am the HERS rater working on a 80+ story condominium high rise. It is intended to be a "smoking permitted" building. Some of the residential units have in-unit access to the elevators.

I'd like to know if I can fulfill the prerequisite, without constructing an ANTEROOM? and if a double door can be an acceptable alternative or not? thanks

Hello, For an office project in Europe, using revolving doors, does LEED still require 25 feet distance between smoking area and entrances ? Thanks

Hi, Our project is mixed use commercial office building including hotel. There are about 100 guest rooms on hotel floors, and smoking is permitted in 30% of these rooms.

Hello, We have recently received a remark from a review that our designated smoking zone is not compliant since it is not 25 feet away from concentrations of building occupants and pedestrian traff
