It’s a bit overdue, but I did promise to write a report on my trip to China, to attend #IPHC23. (23rd International Passive House Conference.) Here it is.... as long, and probably rambling,🧵. 
I’ll break my #iphc23 report into chapters: 1. Plenary & Policy Overview, 2. Conference presentations, 3. Expo, followed by 4. An editorial. (And perhaps some highlights of the short vacation I took afterwards to #Xinjiang, if I have time.)
1. Plenary & Policy: it was clear from the first moment I landed in Beijing that this event would not be a typical #Passivhaus conference. The Chinese Gov rolled out the red carpet, not just for practitioners, but as an all out International trade event. #IPHC23
#SesameStreet is 50!
Its set is based on a typical #Harlem #brownstone neighborhood. #Brownstones are a type of townhouse that are mainly brick but have #sandstone facades. They became popular in the 1800s and today are an iconic image of #NewYork.

The stone was mainly provided by the #Portland #Brownstone #Quarry which operated for 300 years until it closed in 2012. It was on the #ConnecticutRiver which made shipping easy.
Portland is named for Portland #England, a place famous for its quarries.

Steam-powered machines in the 1800s allowed the #sandstone to be cut and shaped faster and more cheaply than ever before, making it affordable - significantly cheaper than stones like #granite or #marble. The stone is pink when cut but turns brown as it weathers.
