Hi We are working on a Data center LEED project. Do we need to model the fresh air fan for server room area because there were already exhaust fan and fire suppression system?

We have a multi unit high rise residential bldg. and we are attempting to provide natural ventilation to all units using the operable windows and sliding doors.

We are working on a office building in which there is an openspace. The outside openings largely cover 4% of the total floor area.

Our HVAC designer is also the ventilation systems designer on our project.

Shall the person who enters his/her initials under signatory section ( for example IEQp1 or EAp2-1, 2-2, 2-3 ) be registered mechanical engineer (PE) ?

I'm working on a FIre Station with a 7500 sq. ft. apparatus bay. The bay is approximately 75' X 100' with (3) 195 sq. ft. doors on each of the long ends (6 doors total). Ceiling Height is 20'.

Hi, I am conducting a ventilation calculation for the an office building that consists of open office space, conference rooms, corridors, etc.

Dear all experts! I have a high-rise residential building which aim to comply with IEQ pre.1 by combining 2 ways. 1.

We are planning to use local code to meet the prerequisite. There are a few space types for which the local requirement is less stringent.
