About Marc Chow

Marc KF Chow

BSc (Building Engineering – Environmental)
MBA (Consultancy), WELL AP, MHKAAST

A greentech-proptech entrepreneur professionally qualified on green building certification and involved in advanced air cleaning technology development. Marc Chow is a specialist on smart air solutions (IoT+IAQ, Internet-of-Things cum Indoor-Air-Quality). He and his partners have helped many corporations to achieve indoor air quality excellence and to get energy saving in the same time.

Marc is an Accredited Professional of WELL Building Standard from the US, and a member of The Hong Kong Association for the Advancement of Science and Technology. He founded and is operating established relevant companies and brands WOOFAA, XaSER and UrbanClimo with different market positioning and partnership.

He was a building services engineer by training, and had an early career dedicated to smart building automation system with Fortune 500 company Johnson Controls. He graduated in recent years from the Hong Kong Science & Technology Park incubation program on a building energy management project. He is a known figure in Hong Kong startup communities with a vision of green future for generations to come.

IoT+IAQ Specialist

There may be many people with expertise on IoT (internet of things) or IAQ (indoor air quality). But you seldom find one who knows both, now you meet one here who can put two together working in harmony, converting between GreenTech and PropTech proficiently…

Internet of Things (IoT) in the 90’s

Marc dedicated his early career in smart building since his undergraduate study in University of Bath, England.

His internship was placed in the London and Reading offices of Cerberus (a Swiss company on intelligent fire system). He got first job after university in the Hong Kong office of Johnson Controls (a Fortune 500 US company in smart building systems) as a technical sales specialist.

IoT in Facilities

Indoor Air Quality (IAQ)

Professionally trained as a building services engineer, who learns the in and out of all kinds of electrical and mechanical engineering systems within a built environment.

In layman terms that mean centralized air-conditioning system, fire, security, plumbing, drainage and as such.

Marc focused on a niche segment since recent years within that engineering trade, and dug deep in to become an expert among peers.

Engineer Turned Businessman

Engineers are all trained to remove risks, something that a businessman need to know and to deal with everyday inevitably. The gap in between is huge invisibly and many tech-driven startups failed there when crossing over.

Marc found his intrinsic business acumen is indeed much better than his well trained engineering mindset only after few years of work. He then worked 5-year in a regional multiple-trade executive search firm and studied an MBA during that tenure. He than established his first startup in year 2000 as an eBay seller, and accomplished over US$3MM online sales, achieved financial freedom in a decade.

Gap crossed


In 2012, Marc was invited to join as a co-founder of a startup team on building energy management and carbon credit exchange. He was picked because it was rare to find someone who possessed the knowledge domains in both building engineering and e-commerce.

The project was incubated by an institute but the regional carbon exchange market did not evolved as we envisioned. But discontinuation of that project became a start of his own entrepreneurship on IAQ as of now.

Marc has a personality to adopt into the startup community easily and learned its eco system fast. So far he has granted both utilities and PCT patents and secured few trademarks, laying grounds for another level of career achievements.

Carbon Reduction in 2-second

Disruptive method to drastically reduce response time of conventional centralized air-conditioning systems, from tens of minutes to a couple seconds, by using integrated tech of vision AI and real-time monitoring of ambient carbon dioxide level.

It is expected to reduce tones of carbon emission yearly from electric energy saved.
