I can't stand the smell of the office anymore!
Of course, these are just the " strongest" office smells.
per capita indoor PM2.5 intake is as four times as outdoor PM2.5 intake.
According to the survey, Beijing's indoor air is at the "pollution" level for one third of the time, and the average indoor PM2.5 intake is as four times as the outdoor air.Under the same external conditions, the indoor PM2.5 level in the office environment is slightly better than the living environment, and the indoor PM2.5 level above the 17th floor is the best.
Therefore, indoor air quality (IAQ) is more worthy of our attention.
PM2.5: particulate matter with diameter of 2.5 microns or less in ambient air.
TVOC: total volatile organic compounds, indoor all organic gaseous substances.
Formaldehyde: colorless gas, has a special odor of irritation, the eyes, nose and other stimulation.
The above pollutants will cause different parts of the human body, different degrees of harm. Dark pollutants indicate a high risk of cancer after long-term exposure. It can be seen that indoor air quality is closely related to our health.
When you choose decoration materials and furniture, improper selection will increase the release of formaldehyde, TVOC and PM2.5.
Indoor combustion behavior and the use of cleaning agents will release CO2, CO, TVOC.
Usually everyone in the office will use a variety of electrical equipments, such as printers, computers and so on, but little do they know that these equipments will generate static electricity and O3.
The air we breathe at work can have a huge impact on our wellbeing and productivity. Healthy buildings pioneer Raefer Wallis tells Work in Mind that the conversation is increasingly focusing on liability - By Sophie Barton
Ask Canadian architect Raefer Wallis to rate the importance of air quality, and he doesn’t miss a beat. “It outranks food and water,” he says, simply. “We can live for three weeks without food and three days without water, but we can’t survive more than three minutes without air.
“I’m often approached by people who tell me they want their building to be healthy and they’re not sure where to start. But it’s a no-brainer. You’re breathing 15,000 litres of air a day and just a small change in CO2 levels can cause a 10-20% drop in productivity.”
Wallis has been lauded as a “guiding light” for his pioneering work in pursuit of healthier buildings. Based in Shanghai, he created ORIGIN, the largest public resource of data on building materials. He is also the CEO and creator of RESET, a technology-driven healthy building standards and certification program which focuses on indoor air quality and the wellbeing of the occupants. Sensors are used to provide real-time data, which shows fluctuations in air quality and allows building owners and facilities managers to alter their behaviour accordingly.
1 Deeper Awareness
“I’ve been working on this topic for 15 years,” says Wallis. “At first nobody knew what we were talking about or why it mattered, but now internal air quality is a number one concern. We really created RESET to solve the problems we had in China, but now it’s an international system and I’m watching it be applied to projects around the world.
“We started RESET because we realised how volatile air quality was, and that there were no standards for tracking it in continuous time. It should be measured at the very least once an hour, not just once every quarter.
“Over the years we realised we needed to set standards for the hardware and installation too – where you physically place sensors is critical. Then there are the software standards, which form the foundation of RESET. The easiest place to cheat with data is with the software.”
2 Invisible Hazard
“Without question the top global concern is VOCs [volatile organic compounds],” explains Wallis. “The second is CO2, which is more of a productivity and comfort concern, then closely behind that is particulate matter. Then there are geography-specific hazards, such as ozone in places with lots of chemical manufacturing.”
VOCs are released by many of the products that surround us day-to-day, including some paints, glues, wood preservatives, cleaners, building materials, furnishings, copy machines and printers.
“Sources can include some of the glues that go into plywood, pressed boards and veneers,” says Wallis. “There are glues we don’t even think about too, such as those that fill some carpets. Flooring and board materials are often big culprits. Our understanding of VOCs is pretty medieval, but the ability to measure air quality in real-time means the topic is hitting a whole other level of maturity.”
3 The Impact on Wellbeing
As well as health concerns, high levels of VOCs have alarming consequences for productivity. A study by the Harvard School of Public Health suggested a 13% decrease in productivity for every 500μg/m3 increase in VOC. Likewise, a 21% drop in productivity was also associated with a 400ppm increase in CO2. With staff often accounting for 90% of overheads, these represent a staggering cost for any business and a strong economic incentive to implement RESET.
“We’ll show the Harvard study to a client, then run the numbers on a base productivity increase of 10%,” says Wallis. “It’s a conservative approach to the Harvard numbers but, even then, we can show insanely short payback periods of anything from four hours to one month.”
4 A Focus on Liability
“It’s critically important for building owners and corporates to be 100% on top of it – they want to manage and deflect issues before they become issues. Today, the conversations are less about how much more money a company can make if they implement RESET. Instead, it’s more about how much business they could lose if they are shown to have poor air quality.”
