Greetings building science enthusiasts,
Miguel here with a brief mid-summer musing. It's hot out so I figured we could talk about air conditioners for just a moment. Nothing too deep, just a simple few thoughts to stir that summer mind-stew for you.
The New York Times just published an piece on climate change and the role that ever growing demand for global air conditioning plays in the carbon puzzle that we, as a society, find ourselves trying to work out. It's called "If You Fix This, You Fix a Big Piece of the Climate Puzzle" and it's a quick read if you've got a little time. For those of you who want a digested version, we've provided the big points below.
This is a decent way to frame the importance of HVAC, but there's obviously so much more to be said. The salient point for me is that HVAC kind of falls flat in people's ears because it's not as exciting as the other sophisticated technology in our lives. Nobody stands in line for the new designer series of an air conditioner like they do for the newest iPhone.
I can't count how many times my friends' eyes have glazed over when someone we meet in a social outing asks me what I do. I have to unpack quite a lot to explain the relevance of HVAC to the global economy and how architectural and construction processes work.
There are a whole lot of people in the world who don't care about air conditioners beyond whether they work and keep them cool and I don't blame them. It's not exactly Game Of Thrones material (by the way, if you're a fan and didn't know, the new season premiere is this Sunday. Get with it, already). But it's precisely because people find it a little boring that I am so excited that The Times published a front page piece on HVAC's role in curbing climate change.
These little boxes matter a whole lot.
Lawrence Berkeley National Labs just keeps bringing in the heavy hitting data points for us. This is a big deal and should be a huge reason more people would care about HVAC. If you don't talk to your kids about thermal comfort and energy flows, who will?
Bottom line - air conditioning is no longer subject to an American-specific product demand. Much of the developing world is seeing massive HVAC adoption, not always with the most forethought to how to do things well.
This is good stuff. Efficiency needs to be a part of the conversation, but we also need to talk about how we deliver that system in the systems of architecture and construction. Don't let your guard down just because something is "efficient." Demand more of your project delivery.
Policy matters. A lot. Be civically engaged and let your representatives know how we can lead the world in energy policy, especially when it comes to air conditioning. And most importantly, don't forget that these air conditioners are meant to provide comfort and clean air to people. It's crucial to continue the discussion on indoor air quality and thermal comfort rather than just diving down the rabbit hole of energy efficiency. They're not mutually exclusive ideas and, when thought about properly, actually can improve in tandem.
