Marisa Simmons
Temperature gradient and emissivity with IR camera
Recommendations
• Low ε ceilings• Reduce ice rink heat gain in ice
from 165 kW to 8kW
• Reduce chiller need from 328 kW to 171 kW
Cost: $30,000
Paid off in 2 months
PhD Research Using the Campus as a Testbed
Steve Ray: Air Flow in Media Lab Atrium
Experimentally characterized full-scale buoyancy driven N.V.
Full Scale
Atrium measurements: Temperatures, flowrates, pathlines, local velocities
Taken before experiment
Full Scale
6 kW heat provided from light bulbs
Full Scale
Expected plume over heat source
Full Scale
No plume formed over heat source because of reverse flow
Full Scale
Faulty instruments
CFD validated at full scale
Full Scale
First use of full scale in-situ PIV with neutrally-buoyant bubbles for Airflow visualization
Full Scale
Unsteadiness near heaters captured in CFD
time
Full Scale
CFD predicts temperatures very close to in-situ PIV measurements
Experimentally measuredrange
Full Scale

•Automated Fault Detection
•5 Most Important Faults
(Not So) Big Data in Commercial Buildings• Data collected by control system
• Operator concerned about tenant satisfaction
key feedback
• Academic studies on fault detection and identification
• Try a simpler approach
