air quality business possibilities in china
TRANSCRIPT
Why do we need excellent filtrationat air-handling unit ?
• Small particles are very harmful for people• At yearly level 200 000 deths are caused by small particles
in Europe• Otside air is polluted by trafic, industry, burning processes,
pollen and viruses/bacteria
IAQ in ZEB
• Well insulated and tight buildings with good solarshading.• Mechanical air intake with good outdoor air filtering.• Demand based ventilation.• Right temperature, high air quality, low velocitiesand noise in the space.• Low energy cooling and heating technologies andrenewable energy.• Individual control of indoor environment.

Indoor Climate andProductivity
•”A minor 1 % (5 min/day) increase inoffice work can off-set the annual costof ventilating the building.”•”Doubling the outdoor air supply ratecan reduce sick leave prevalence by10 %, and increase office work by1,5%.”

Topic to Discuss: Who Cares ?• Demands and business models of different building
segments (apartment, public buildings, commercialbuildings) ?
• Is the driverØ Perceived IEQ Conditions (voluntary based )Ø Heath Risk (regulations or voluntary based)Ø Demands of Carried out Process ? (monetary risk of
malfunction)
Topic to Discuss: Business Model
• To whom Indoor Air Quality reallymakes value ?
• Is the offering: technology, totalsolution or service ?
• What is the model of go-to-market ?
