The Masdar Institute of Science and Technology (MIST) in Abu Dhabi, UAE is one of the world’s most sustainable facilities with a near net zero carbon footprint. MIST buildings 1A and 1B comprise mixed-use lab, office, classroom, and residential space over some 150,000m2. The region has a severe climate of very high temperatures, similar to that of India, but with even higher relative humidity (RH).
MIST used DBC in its classrooms and office areas to reduce ventilation based on determining occupancy by sensing CO2. In the labs, DBC is used in conjunction with either chilled beams or fan coil units to reduce lab ACRs to 2 ACH day and night when lab air is sensed to be clean. When contaminants are sensed, purge airflow rates of as high as 14 ACH are commanded to provide greater dilution than the fixed minimum of 6–8 ACH for safer operation.
The lab’s VAV fume hoods were initially designed to go as low as 150 l/s when the sash was closed but, due to the new ANSI Z9.5 standard, a VAV fume hood minimum of 45 l/s increased energy savings further.
DBC is providing savings for this project that will be around 9,000MWh p.a.
