Hi, I am working on a large project in Australia that has used local code. The local code is more stringent than 62.1 however needs to be documented for the submission.

Dear all! How do you show compliance with case 1 for GBCI, mixed-mode ventilation?

I have a project looking to achieve some of the spaces via Natural Ventilation compliance. The windows are installed with a 60% porosity window screen.

we have a new addition added to an existing facility.

I have project with a dedicated outside air system that introduces air directly to the spaces on all levels (i.e. neutral air). The project has more than 100 VRF units.

We have a mechanical ventilation system that continuously supplies OA air into each apartment. Each apartment has a fan coil unit that conditions the apartment.

We have a project that is predominantly a parking garage structure.

We are pursuing for Fresh Air calculations for a Building with Natural Ventilation, as per the ASHRAE 62.1-2007 requirement, stated under the IEQ Prerequisite 1 – Minimum Indoor Air Quality Perform

We are working on a small building that will operates for conferences and private events. There will be a kitchenette or coffee point (only microwave, coffe maker and refrigerator).

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