slide-3
SLIDE 3 Understand what buildings can and should do to reduce potential exposure to COVID-19

Learning objectives

+ Explain short-term solutions for MEP systems, including maintenance for plumbing systems, electrostatic cleaning, and dilution ventilation Understand long-term systems MEP system modifjcations, including MERV fjlters, UVGI, PCO, ionization systems and humidifjcation Explore costs for various solutions
slide-4
SLIDE 4 Hope is not a strategy.
slide-5
SLIDE 5 + Increase Fresh Air + Increase Airfmow in the Building + Increase Filter Effjciency + Possibly Add Active Mitigation (UV-C lights or Electronic Air Cleaners)

Executive Summary

slide-6
SLIDE 6 Dilution Ventilation Short-Term Flush out the bad and bring in the clean.
slide-7
SLIDE 7 Dilution Ventilation Short-Term What’s the cost?

SLIDE 11 UVGI (ultraviolet germicidal irradiation) Long-Term Kills what it catches.
slide-12
SLIDE 12 UVGI (ultraviolet germicidal irradiation) Long-Term Concerns Options
slide-13
SLIDE 13 UVGI (ultraviolet germicidal irradiation) Long-Term Incorrect design and installation is dangerous and inefgective Protect the People

SLIDE 14 UVGI (ultraviolet germicidal irradiation) Long-Term What’s the cost? Cost
slide-15
SLIDE 15 PCO (photocatalytic oxidation) Long-Term PCO reduces airborne virus, biologic and VOCs with every volumetric air change through the system.

SLIDE 20 Ionization System Long-Term Options Concerns
slide-21
SLIDE 21 Humidifcation Long-Term Reduces airborne transmission from person to person.
slide-22
SLIDE 22 Humidifcation Long-Term How does warm air hold more moisture?
slide-23
SLIDE 23 Humidifcation Long-Term Options Concerns
slide-24
SLIDE 24

Impact to productivity and

slide-25
SLIDE 25

Cost to double ventilation rates $40/person/year Productivity benefts $6,500/person/year

SLIDE 26

MEP options are subjective and will vary greatly in cost and approach, dependent
