I would like to know if there is a maximum obstruction height of views for option 1.

I am working on a residential building, the exterior wall assembly as R-19 fill cavity between studs for an 3.5" depth (wood studs 2x4 16" OC) but in the ASHRAE table A3.4, there is no value menti

We have one non-compliant product on the project to date. It is a PVC glue- less than a liter was used.

Are there any conflict of interest concerns if a contractor hires the air testing company versus the owner or A/E?

Does the steel stud count as different material than the track?

I have a building registered under LEED NCv2009, that is being built entirely within the LEED boundary of a certified LEED NCv2.2 Gold project. Same owner.

Hi, Our project includes railway station within the LEED ND v2009 project boundary, but no bus stop.

We are designing apartments with mixed mode ventilation--the areas within 25 feet of a window will be naturally ventilated and the rest of the dwelling units will be mechanically ventilated.

Our project is a 4-floor fit-out of a hospital tower (Less than 200,000 SF of an existing 8 Million SF building).

I have a project that is undergoing discussion regarding which rating system to use. For all practical purposes, it is an interior fit-out of 4 floors of a hospital tower for a new unit.
