i'm wracking my brain here trying to remember this building...somewhere in asia i believe...that has semi-magnetic fins on the exterior that attract particulate matter from the air and holds them in place. over time, they grow like moss and the fins can be removed and cleaned.
i think it's obviously in a high density urban environment. shanghai? beijing? tokyo?
heads up...two beers on me to the first person who names it correctly. esp. if you're in the bay area, then the beers will be paid. otherwise, you'll have to come here and visit for payment.
well, ive been to this building that had a chinese restuarant and the ground level and that attract particulate matter from the air and holds them in place. over time, they grow like moss and the fins can be removed and cleaned.
haven't seen any building with moss collecting magnetic fins that require swabbing off.
there are two material that I know of that have 'self cleaning' properties. there is a glass coating from pilkington or saint gobain that reacts with UV and water to shed all dust/dirt that land on it.
the other is an activated concrete that catalyzes ozone/NOx into less reactive gasses. not sure who makes this, try CEMEX or any of the large cement companies.
when it comes to air cleaning- ignore the 'ionic breeze' hype and get hepa filters. also avoid any filter that claims to produce ozone to purify the air- ozone is a pollutant and bad for your health. electrically charged metal fins will collect some dust but not very effectively in an open system - that's called electrostatic precipitation when used in industrial settings. they tend to use higher voltages then safe for architectural settings...
thanks for the info tk. though not exactly what i was looking fork, the pilkington/saint gobain coatings might be of use to me. any idea what they're made of? are they integral to the glass, or painted/overlayed? can it chip and/or scrape off?
i'm pretty sure the thing i'm thinking of is already in place and is in an open system. i don't believe it was a cement based operation, but more along the lines of electrostatic precipitation.
i'll keep searching. will definitely post image/info if i find out what it is/was.
no. but that's cool too. this was definitely not an individual product that had an inherent capacity like the tit.oxide in meier's church...but an active system of both static and mechanical components, currents and what-not.
Quick question about an architectural pollution control device...

no no no. wrong sir!
sorry, no deliveries to highgate. only to berkeley.

the coating is integral to the glass/baked on metal oxides of some sort. the glass companies websites will have more details...
Is this what you are looking for?
