We are working on an office project. The typical floor will be a completely open space, with workstations and meeting spaces (not enclosed). This will not be a densely occupied space.

Hello everyone, I am working in a underground metro station which is aiming for LEED certification.

To comply if the requirements of this credit, could we installed CO2 devices, instead of outdoor airflow mesurement device, in non-densely occupied spaces?

Hello, We are working on a project which is an industrial plant, the building will be mechanically ventilated.

Hi, We have a project, where there are large directors' offices.

Dear Sir/ Madam, I have a project that is a hotel with 200 guest rooms that are non-densely occupied. Each guest room floor (20 rooms per floor) is supplied with 3 AHUs.

We have a large residential project that has natural ventilation being used. Are CO2 sensors required in every room/bedroom of the apartments?

We are working on a project that has a fancoil located on the top of the building that will treat the outdoor air and deliver it to each non densely occupied zone.

Hi All -- I see my question might already be partially answered in the conversation from May 28, 2013.

I need some clarification on what definition of a "ventilation system" would be with respect to design that uses a DOAS unit that provides outdoor air to each space.
