Why is indoor air quality such an issue in China & India?

• Lagging regulatory enforcement and lack of mandatory disclosure

• High levels of outdoor pollution infiltrate into indoors

• Frequent renovations + poor materials

• Few providers with understanding of IAQ

• Misinformation about what solutions really work

• Growing levels of awareness & single child policy (China)


• Conclusions can be listed here.

The Dilemma – outdoor polluted, indoor polluted

IAQ problems typically treated by flushing with fresh exterior air

In China and India, outdoor air is highly polluted and not “fresh”.

External ventilation is very expensive

due to heating/cooling costs. Energy

grid constrained in India



Yet, opportunities abound

China :

• Population of Shanghai alone is more than LA, Chicago, Houston, Philly, Phoenix, San Antonio, San Diego and Dallas combined

• China has more billionaires than any other country and the largest middle class

• China used more cement in last 3 yrs than US used in entire 20th century

• #1 country in LEED and WELL registered projects

• Govt has committed to $220B to fix environment; this is >25x the US EPA’s entire 2017 budget

India :

• 14 of top 20 most polluted cities of the world in India

• Over 4 Billion square feet of Green Buildings in pipeline / committed (IGBC)

• Air filtration industry growing at CADR of 50%+

• Big demand for Grade A properties –Certifications for Green Buildings, WELL, RESET achieve premium

• Awareness increasing and demand is coming from the bottom-up

Primary IAQ Concerns in China and India

PM

VOCs

Mold

Asbestos

Radon

Why: High media attention; visible; easy to address

Sources: High outdoor pollution

Why: Traditional fear; high cancer rates (more in China)

Sources: Renovation, construction materials, industrial

Why: Little recognition of danger

Sources: Poor construction practices, high RH

Why: Little recognition of danger

Sources: Construction materials

Why: Little recognition; no disclosure; low standards

Sources: Soil, subgrade, poor ventilation



What is the market environment like?

China India

Pricing Commoditization of lab testing and purification hardware; extremely wide range of pricing and quality

Extremely price sensitive; mass market price point may be even lower than China; at same time, small ultra rich segment

Marketing Residential: Social media Commercial: Via ecosystem advisors; thought leadership; can buy your way in

Word of mouth very strong; smaller circle of influential business elites; thought leadership and industry organizations

Competitors Increasingly fierce; low barriers to entry, but innovation or new technology can provide advantage; few consultants

Fast to move and copy business models; stronger in service/consulting; fewer tech or hardware based home grown firms

Ecosystem IAQ not well understood by HVAC or MEPReal estate service providers and designers are key channels

Heavy engineering and consultants; less manufacturing base; few professional testing labs

Govt influence Strong but hard to get into Open, but slow to move or change; strong regulations, but poor enforcement

Key trends Monitoring; Smart-offices and homes; AI; domestic growing faster than foreign firms; green building and wellness

Fast increase in public awareness; green building



What Drives Demand? (not regulation)

Information

AccessibilityDistrust of authority and

increasing role of technology



Demand is very socially driven

Massive, viral social and online

networks

Self-funded, self-produced environmental documentary was viewed 150 MILLION times in 3 days


Only in China: Management Held Hostage by EmployeesFlipside: Spending on IAQ = Investment



What overseas practitioners can learn from India & China (or, keys to success)

Market

• How to respond quickly to aggressive competition, shady business practices, IP copycatting

• How to win tenders and know how to partner in the ecosystem

• How to manage quality which cannot be taken for granted (mainly suppliers and installers)

Technology

• How to filter extremely high levels of PM

• How to do this while saving energy

• How to remediate VOCs

• How to monitor, analyze the data, and use real-time data to automate operations

• How to screen technology and performance

Client Management

• How to sell “good enough” at a very aggressive price

• How to educate clients on standards

• How to sell on individual motivations instead of product features

• How to manage multiple stakeholders


Monitoring and Automation – the keys to ensuring clean air and energy efficiency

Am I getting the results that I

have paid for?

Am I wasting energy and

spending too much on filters?

2019 IAQA Annual MeetingAir Quality Monitoring

5 KEY IAQ PARAMETERS

PM2.5 TVOC CO2 RELATIVE HUMIDITY TEMPERATURE

UNIT OF MEASURE µg/m3 mg/m3 ppm % ℃

MINIMUM TARGET 35 ⩽0.5 ⩽1000 Measured Measured

HIGH-PERFORMANCE TARGETS

15 ⩽0.4 ⩽600 Measured Measured


“B” Grade Sensor with 5 parameters


Monitoring

(IAQ Monitor & Online Data Management)

Real-time IAQ monitor that measures PM2.5, TVOC, CO2, RH and Temp

• Grade B (Commercial Building Grade) as per IAQ RESET Certification

• Web-based dashboard

• Validates system performance and allows for continuous improvement

• Alerts when air becomes unhealthy based on set threshold

• Notifies if filter needs to be changed out of schedule

• Connect via WIFI or 4G adapter


Automation & Continuous Monitoring have many benefits


On-demand automation vs Manual operation in terms of PM2.5 reduction trend[6]

Using real-time monitoring data to automate operations also saves up to 70% energy (compared to continuous operation)

History & Development of Electrostatic Precipitation (ESP)

2nd Generation: Plate Type ESP Technology;

Main Application: Commercial air purification,

Kitchen smoke;

Typical Products: Wire ESP; Sawtooth ESP.


Problems with ESP

• Ozone generation (key issue in occupied spaces)

• Arcing (crackling sound and fire hazard)

• Short life due to caking of particulates on metal plates

Intense Field Dielectric

IntroductionIFD stands for Intense Field Dielectric. IFD is similar to

traditional ESP but takes advantage of updated

technology for charging and particle collection.

IFD filters can be installed into the filtration section of

AHU/FAU, to remove PM2.5 in the fresh air before it

enters into the occupied space. IFD filters can achieve

more than 95% filtration efficiency.

• Next Generation of ESP filtration technology

• Easy to retrofit into different system types

• No consumables – filters can be washed

• Long service life 8 years


IFD VS Traditional ESPIFD V.S. 傳統ESP

No Arcing, Safe and Silent 無電弧、安全和靜音The collector has no bare electrical components. The electrode

surfaces are encased in a special dielectric (non conductive)

material, which prevents arcing between the electrodes, there for it

is safe and silent.

Low Power Consumption 低功耗By intense electric field with micro-pores, Micro-ESP’s power

consumption is just about 1/10 that of the plate ESP.

Lightweight 羽量級The collector is composed of electrodes and unique polymer flute

materials, which is light and easy for installation, maintenance,

cleaning.


What if it is possible to have the

best of both worlds as electronic

filtration embedded in a mix that

works?


Smarter HVAC can achieve this


Proactive measures and remediation for VOCs (particularly after renovations)

Industrial grade

portable carbon filters

for VOC scrubbing in ambient air

Photocatalytic oxidization (PCO)

treatment for reduction of emissions in

materials

MHCC: Multifunctional High Efficiency Catalytic

Cleaner filter blocks (install in HVAC or

recirculating systems)


Pressurisation can be key to clean air – specially in old leaky buildings


Combined with recirculation units, can give the best results


Residential Air Purifiers are a BIG trend in China and India


Again, positive pressurization for a single room gives best results


RESULTS COMPARING NORMAL AIR PURIFERS WITH POSITIVE PRESSURE


Natural Plants also used for filtration & lower energy
