Welcome to our webinar MG D EH&S UCI Thanks for letting us share our experience with…
UC Irvine is a growing…
This study asks the question…
As you know, lab ventilation rates are often set at a constant rate between 4 to 12 ach These rates are frequently excessive during low level process activity and non occupancy This study explores the possibility of a set back based on lab pollutant concentration
The following diagram summarizes the …
This CDCV system begins with: room sensors to measure the quality of the air in many locations of a building An air router pulls the air sample to the Sensor suite that analyzes the air sample for… An information management server tells the VAV controller to increase or decrease air flow All this data is logged into a computer for analysis
The result is by monitoring air contaminants, we can make decisions about reducing or increasing ventilation rates in the building
Our goal is to find the sweet spot where we maximize energy savings without compromising safety.
Our recipe for taking on an ambitious project like this is to have a multi-disciplinary team of professionals focused on a common goal. At this time, Rebecca Lally will tell you about our study
This slide demonstrates air samples being taken from various locations.
If there’s a delay in the activation of the ventilation system, higher concentrations will result. Therefore , data did not prove that CDCV provides for a safer lab, slower response in ramping up, higher peak concentration. Pick another lab that can reach stable ACH.
