Dear All,

We are working on a naturally ventilated residential project with 295 dwelling units. The project comply with the monitoring requirements. 

Would it possible to input zero for an occupiable storage rooms for liguids and gels in the Minimum IAQ Performance Calculator?  I ask because the building in question is a maintenance garage

Hello,

The project is located in Europe and standard EN 15251 is considered for the achievement of this prerequisite.

Hello everyone,

On our project we have a few spaces like corridors and break rooms with kitchen area which don't have a direct ducted air supply from the AHU (CAV system).

Is the IEQ Space Matrix still relevant for this Prereq under v4?

We are working on a YMCA with multiple single zone packaged rooftop units.  The engineer has designed every unit with CO2 based demand control ventilation to reduce energy use.  The units

The corridors are separated from the staircase by two doors in order to create a space (buffer space) whose walls and doors are fire-resistant.
