Our project is designed with a 4 pipe fan coil system supplied by a central plant which thermally conditions the following type spaces; dormitories, active and passive common rooms (study/ recreation lounge), classrooms, conference rooms, and administration offices. We propose to meet the credit intent by incorporating the following strategies. The dormitories are designed for natural ventilation through operable windows sized to exceed EQ p2 requirements and will have a CO2 sensor that sends an alarm to the BAS when levels exceed 900 ppm. All other space types will receive outside air through a constant volume 100% OSA AHU located on the roof with airflow measuring stations that sends an alarm to the BAS if the design outside air monitors a change of +/- 15%. The active and passive common areas, classrooms, and conference rooms are considered densely occupied and will have a CO2 sensor that sends a signal to the BAS when CO2 level exceed 900 ppm. Our credit interpretation request is to confirm that for densely occupied spaces with our above system types that sending an alarm signal to the BAS meets the credits intent. It is unclear if an active means of bringing increased outside air to the densely occupied spaces is required.
