People often make annoying rebound effect claims where they suggest that offsetting energy savings with higher consumption is somehow bad. This feels completely backwards. It feels more likely that energy reducing technologies are critical to improved human living standards

People think doors and windows are responsible for a loads of air leakage but they're not. How do I know? Because we've systematically measured leakage in almost every building we improved for the past 15 years

There's no better example of a blue state shooting itself in the foot with petty and excessive administration than NJ municipalities requiring a zoning permit for a replacement AC or heat pump outdoor unit. Here's why!

Testing which terminals on this relay close using 12v DC power from my truck looks like something from bad idea jeans

I also condemn whoever this is. Also happy to meet with them and kick them out or whatever

I haven't heard this discussed but the way I graphically show heating a house with an air source heat pump is basically the econ 101 supply and demand graph

Taken from a Swiss prefab plant. Not sure if this is common but it seems odd that this isn't substantially better tech than a pneumatic stapler that's common to job sites. The main efficiency gain appears to be waist-high tables

My kids' school had an overnight "fire alarm". It's somewhat more likely to be a CO/smoke detector that's correctly triggering on CO. Things I'd check 1) natural draft boiler or water heater, possibly coming out of thermostatic setback not drafting due to cold flue piping.

One of the reasons I think HVAC is dominated by incompetence vs just greed is because people often can't buy their way into higher performance. So extremely high-end houses end up with some of the worst performance as their systems become increasingly complex
