The Phoenix Controls Legacy “We Don’t Measure Flow”
• Flow Metering vs. Flow Measuring• Flow measuring has a limited range of
operation.• Flow measuring requires long, straight duct runs
(not available in most applications).• Flow measuring is prone to inaccuracies due to
the caustic nature of laboratory exhaust air• Flow measuring has inherent time lags due to
airflow dynamics• Flow measuring requires periodic maintenance

Factory Calibration
• Drastically Reduces Commissioning Time• Can be pre-commissioned before supply and
exhaust air is connected• No sensors to set up or flows to adjust • No routine maintenance requirements

Energy Saving Products and Applications
What does One (1) CFM of “Single Pass” Air cost to heat and cool at The
Ohio State University?
Phoenix Controls Corporation—Proprietary and Confidential
What Can Be Done?
• 6 energy saving trends in Laboratory Airflow Controls• Usage Based Controls®
• Fume hood decommissioning• Energy waste alert• Unoccupied settings• IAQ control ventilation
Phoenix Controls Corporation—Proprietary and Confidential
Proven Energy Saving Concepts
Phoenix Controls Corporation—Proprietary and Confidential
Usage Based Controls®
Phoenix Controls Corporation—Proprietary and Confidential
Lab Usage Patterns
• 24‐hour operation• 100% outside air (no recirculation) • Hood occupancy in short segments • Total hood usage typically one hour per day
and independent• Sash management varies widely
Usage Based Controls
Phoenix Controls Corporation—Proprietary and Confidential
Zone Presence Sensor®
• Available since the mid‐1990’s• One ZPS® per 8' hood
• Can be used in series for wider hoods• Field programmable via a USB port

Fume Hood Decommissioning
Phoenix Controls Corporation—Proprietary and Confidential
Concept
• Ability to reduce or turn off fume hood exhaust when not in use
• Potential for huge energy savings • Teaching labs or hoods rarely used • Buildings not occupied• Understaffed research facilities
• Valve options• Valve minimum (i.e., 90 CFM)• Shut‐off Valves (i.e., 0‐5 CFM)
Fume Hood Decommissioning
Phoenix Controls Corporation—Proprietary and Confidential
Function and Operation
• Can be initiated by: • Fume Hood Monitor
• Button sequence• External key switch• BMS command
• Ensures safety• Sash must be fully closed to initiate mode• Mode is automatically exited if sash is opened
Fume Hood Decommissioning
Phoenix Controls Corporation—Proprietary and Confidential
Energy Waste Alert
Phoenix Controls Corporation—Proprietary and Confidential
Concept and Operation
• Notification when sash is left open and lab lights are off
• Features• Light sensor incorporated in monitor• Provides audible alarm• Displays "EnrG" on monitor
• Reminder to close the sashes at night
Energy Waste Alert
Phoenix Controls Corporation—Proprietary and Confidential
Unoccupied Settings
Phoenix Controls Corporation—Proprietary and Confidential
Unoccupied Settings
• Celeris®, Theris™ and Traccel® digital platforms• Lower ACH• Relaxed temperature control• Triggered locally or via BMS schedule
• Retrofit existing analog systems• Lower ACH
Phoenix Controls Corporation—Proprietary and Confidential
IAQ Control
Phoenix Controls Corporation—Proprietary and Confidential
Two Ventilation Concepts
• Air change rates• Reduce minimum ACH when air is
"clean"• Drive to higher ACH when
contamination is detected
IAQ Control
Phoenix Controls Corporation—Proprietary and Confidential
Lab Application: Next Generation VAV Control• Lab Multi-parameter DCV: Dynamic control of min.
ACH• Now all three factors affecting lab airflow can be varied• Significantly cuts energy & first cost, while enhancing safety

• Carbon Dioxide (CO2)
Phoenix Controls Corporation—Proprietary and Confidential
Lab Monitoring Also Helps Ensure Lab Safety
• Validates the safe operation of a lab• Detect improper bench use of chemicals • Detect poorly containing fume hoods• Spills & rogue reactions rapidly sensed• Check lab pressurization, T & RH• Validates safe IEQ room conditions for animals
• Allows for safer lab airflow control• Increased hood capture from reduced drafts
• Drops room flows when dilution not needed• Greater dilution provided for spills, leaks, etc.
• 12 to 15 ACH’s can be provided automatically• Sources of leaks & emissions can be found
• With fact based data, source controls can be used

What it all means…
• Like most life-sciences labs, the airflows in Biodesign-B are primarily ventilation driven.
• Most labs in Biodesign-B are over-ventilated• Average ventilation flows can be safely reduced by >50%
when monitoring air cleanliness and responding to spills, etc.
• There are HUGE energy savings with FAST payback! • Several other soft benefits too!
• Safer hood operation• Quieter labs• Documented performance

A “Working” Laboratory
How Do you Define a “Working Lab?”
Phoenix Controls Corporation—Proprietary and Confidential
A “Working” Laboratory
• What checkpoints are in place to assure that labs are working?
• Are specifications being met?• What are the consequences?• What documentation of performance is required?• Who suffers if the specification is not met?
Phoenix Controls Corporation—Proprietary and Confidential
Laboratory Recommissioning
• Documents laboratory performance• Fume hood face velocities• Lab pressurization• Energy Usage
• Identifies Energy Savings Opportunities• Airflow reduction• Static pressure reduction• Other opportunities
Phoenix Controls Corporation—Proprietary and Confidential
Our Commitment
• Superior system performance• Local, factory certified technicians starting up each
project• Full commissioning of each system
• Airflow checked for each laboratory condition• We strive to make system “fail” instead of the easy route to
pass.• Contractor Support• Three year warranty on all equipment• Project budget is maintained
