How do one determine minimum outdoor air intake flow of a VAV system coupled with demand controlled ventilation to comply with ASHRAE 62.12007 standard required for at different operating condition

It seems that the certification reviewers do not know when heating and cooling occur in a space.

Hey andrew.

Hello, IEQ-p1: Work code is more stringent than ASHRAE, so we'll use work code air rate to justify prerequisite The question is: we want to obtain the IEQ-C2 increasing by 30% the air rate BUT o

Good morning everyone.

Hello, I am trying to determine whether or not I am calculating Ds correctly.

We have an electrical room on site that is not attached to the main building and will hold the electrical equipment for a diesel fueling station.

Dear Concern:- Is there any MERV filter requirement for IEQ PR 01 credit as per ASHRAE section 5.9 (is it mandatory) What are the Ez values should be used for below equipments????? 1.Fresh air f

Our project is use VRF system to keep the space cool. We also provide dedicated injection fan (DOAS) as to meet 62.1 requirement. Most space will have indoor cassette unit.

Is it safe to say that if a project acjhieves 60% improvement over ASHRAE 62.1 outdoor air ventilation rate that the project would be likely to receive an innovation credit if applied for?
