The document discusses smart lab buildings and strategies to balance lab safety and energy efficiency. It describes centralized demand controlled ventilation that monitors indoor air quality and varies ventilation rates accordingly. Low flow fume hoods and exhaust system optimization are also discussed. A case study of Gross Hall at UC Irvine highlights these smart lab features, including occupancy-based lighting controls and estimated 50% energy savings compared to code. Challenges of maintaining smart lab systems and obtaining code compliance are also noted.
