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, I am working on a residential building oversees seeking LEED Silver (V3). To comply with IEQc.5 we are installing MERV 13 filters on all fresh air intakes.

Hello, I am curious about implimenting natural ventilation in climate zone 6 where the winter temperatures can be very cold.

Can anyone please clarify which, if any, ventilation requirements are applicable to shower spaces whithin a sports facility (e.g. exhaust rate per shower) under ASHRAE 90.1 (2007)?

Has anyone had an issue with complying with ASHRAE 62.1 for natural ventilation of a space that is being used as a maintenance garage? We have 3 garage doors that are open to a large garage type a

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?
