Happy #ThermalThursday everybody!
What stories go with this image? Here's one: #Pittsburgh PA is no longer "Hell with the lid off," as it was when Andrew Carnegie and Henry Clay Frick were perfecting the art of industrial steelmaking. But I was pretty surprised to find this active metal smokestack, smack up against the guardrail of a nice terrace with seating overlooking the Monongahela River, toward the Golden Triangle of downtown. And so, the products of combustion once again appear to overwhelm the atmosphere of this city.
Welcome to my world! Back to buildings: You can see the differences in emission of infrared light from the four main skyscrapers in the photo. This reveals information about the effectiveness of their thermal barriers, although the different emissivities of their exterior finish materials, and the mist from the smokestack, do complicate this evaluation.
And, in 2024, more than a century after the ramp-up of Pittsburgh's steel industry, we are still too dependent on burning fossil fuels to power our lifestyles - myself included. Have you thought about how combustion produces more carbon dioxide by weight than the weight of the fuel that we burn? In an excellent "All Things Facades" podcast with Adrian Lowenstein, P.E., MBA and Eliot Benor this week, Carl Ian Graham explained that New York City's game-changing #locallaw97 is saying, "I don't care how much you spend on your energy bill. I want to know what you are using to heat and cool your building. And each of those has a CO2 impact." It is no longer okay to require combustion-based mechanical systems to make up for huge amounts of space conditioning energy loss through inefficient building envelopes.
