Talk about air quality in homes
Indoor air quality in buildings is important, especially in homes where the homeowners often do not understand about HVAC – why, how and what. I found this great study about participants in homes and air quality monitoring with features important for understanding the air quality indoor and around their homes.
The World Health Organization (WHO) estimates approximately 3 million people die annually as a result of ambient air pollution. Because people spend more than 90% of time indoors (out of that more than 70% in homes), exposure to fine particle matters (PM2,5) has effect on health linked with increased cardiac problems, lung cancer, heart disease and many others.
Many buildings and homes have already good HVAC systems that are connected online and are based on large quantity of data to be able to operate at the right levels. These monitoring data are often hidden from occupants, or often it is problem to “translate” these amount of data to visible and understandable way to occupants. Yet, these data can capture the additional value to occupants, observe the situation in their homes and draw insights from the data.
What people think about air quality in their homes when seeing the monitoring data?
Here are some interesting facts from occupants about the air quality in their homes.
1: “It was nice to see there are differences, like what’s going on in different rooms. If there’s just one sensor for an entire house, it doesn’t really tell you anything.”
2: “I find it humorous that I can tell the days – when it’s a Wednesday, my husband works from home and lights incense in the office downstairs, and there’s a spike downstairs.”
3: “I was definitely looking at the kitchen a lot because I think things change a lot more in the kitchen than the bedroom. Everything that happens in the house, happens in the kitchen. So it was always interesting when I saw a bedroom spike because . . . what did they do? Seems really strange.”
4: “I wanna see what’s happening with all three sensors. The outdoor is usually the one that stands out. Historically, that’s where the higher [readings are].”
5: “Sometimes you feel that people are like, oh, you should stay in because the [outdoor] air’s bad. But, is it really that much worse than what’s in my house?”
6: “I have learned to pay a lot more attention to the difference between the air quality inside and the air quality outside. I think previously, I just kinda assumed that the air quality inside was always really great, because our windows are shut and our doors are shut and we don’t open our windows… and that’s what I was told: just don’t open your windows and use air conditioning and you’re good. But I realized that’s not really always the case. And that’s been a big eye-opener for me.”
