The biggest leaks will be frame-drywall, holes in wall plates for electric and piping, and holes in drywall for electrical fixtures/junctions. Also frame-frame (eg subfloor to joist), and frame-foundation

Specific to most US homes post ww2. If you think of a building cross-sectionally, you'd want to trace the layer that's tightest. In most cases this will be mainly drywall on exterior surfaces, which will connect with framing plates, doors, windows, electric fixtures

This is a manometer, which is connected to a blower door measuring leakage in a home. This is the pre and post air sealing test. In this case we've reduced air leakage in a home by nearly 30% in a single day which is fairly typical. We've retrofit roughly 2k homes

Iirc Vancouver BC actually does mandate ASHP vs AC
comment in response to
post
No, NJ allows standard AC, just that they push for heat pump conversion via rebates and loans
comment in response to
post
Yes, minimum of 2 permits, although typically zoning and HVAC. HVAC is administered via bldg dept and zoning is usually separate. Many jobs also require an electrical permit

3) NJ has some of the most aggressive policies and rebates promoting heat pump conversion, and replacing outdoor AC units with heat pumps is a mandatory part of most conversions. We're needlessly adding weeks to this process

2) It's politically untenable to deny people heat or cooling so it's not clear there's a path for rejection even when the original - and thus replacement - units run afoul of a zoning rule
comment in response to
post
1) Zoning is mainly concerned adding impervious area or encroaching on adjacent property. Neither of these are changed absent unit relocation

Precisely. This is the only acceptable solution anything else is eugenics

Same but for me it's because saving one is quantifying and saving neither isn't

Sorry bud you're appallingly ignorant and show no inclination whatsoever to engage in good faith. Blocking you

Sounds suspiciously like an attempt to quantify which I know you don't believe in

Interesting. I've had the vague sense this was the case but wasn't sure. Sucks

You had a disagreement over philosophy with someone on the internet and typed "my enemy". Might be time to calm down a bit

Ditto the flimsiness for Musk's EA association. He positively tweeted about WWOTF in 2022. Partly of the problem may be that unhinged people engage in public ideological careening which gives detractors at least some material

Sorry bud you're exceptionally poorly informed and insulting. Blocking you

Ah. He praised a book about longtermism in 2022. I guess that's somewhat close to him praising EA, but not quite buying in on EA philosophy. So I guess in my hypothetical add that 3 years prior to defunding Christianity Trump praised a facet of Christianity in a 2 line tweet

You honestly believe EA is spearheading or supportive of decisions to deprive people in poor countries of HIV meds? It sounds like you should be the one looking into stuff tbh
comment in response to
post
Musk doesn't identify as an EA and EAs don't identify him as EA. It's more like If Donald Trump said he wasn't Christian and Christians agreed and he somehow illegally cut funding to Christian causes and all the Christians were like omg this is horrible, stop, but then someone said see! Christian!

This is a bit silly though. Suppose you fucking hate someone for value based reasons like racism and someone comes along and says oh you must love so-and-so he's an unrepentant racist like you! Then when you respond defensively the person says oh you're doing defensive disavowal that looks bad
comment in response to
post
I think he's fallen off quite a bit in praising EA and his actions are antithetical to its values. I just bashed the Tates to MMA IG so I'm a bit overwhelmed so will see about addressing the eugenicist thing later maybe. Happy we agree that EAs support helping the global poor and that this is good
comment in response to
post
Yes consider 2 options. 1) we think you've misinterpreted EA ideas and adherents. Or 2) we've put quite a bit of effort into organizing and donating to ghd, protesting pepfar and usaid cuts and we claim the people who did them aren't us. But we're deceiving or can't identify our leaders or?
comment in response to

Yeah I've made a huge error in judgement but luckily you've clawed me back from the edge with your comment tx
comment in response to
post
It's a bit frustrating to read this is EA-orchestrated when EAs have done more than most to protest pepfar and USAID cuts, often donate to other ghd interventions and participate in these directly (my wife runs an African palliative care non-profit). It's a flawed movement, but this is totally off
comment in response to
post
No the argument is more like this is blatantly false and advancing global health and development is central to ea, musk and doge have nothing to do with ea and don't purport to hold the ideology. So yeah just a lot of bullshit

This is one of the weirdest takes I've ever read. We actually hate that fucking guy. We're very anti withholding lifesaving HIV medications from poor people

Yeah this is cool but Jesus that's a lot of end user effort

Fossil fuel devices aren't exactly this but it's pretty close. So boilers and furnaces are much easier to understand. This is one of the major problems that ashp proponents have to contend
comment in response to

Meaning in split ac/ashp systems vs the current small refrigeration market here? I don't follow it that closely but it looks to me like r454 will dominate this regulatory update
comment in response to
post
Pasted from x and some was snipped. Yes climate control and lower wage workers. But this needs to offset transit costs which is hard to do if site productivity is roughly equal to factory. Prefab has been a 60 year siren song imo
comment in response to
post
Regulatory barriers are commonly given as an explanation for flat construction productivity, but I don't find this entirely compelling. Partly we should acknowledge that post WW2 platform framing was radically transformative and as of yet difficult to rival
comment in response to
post
The state of US prefab could become interesting. It could be that prefab catches on as labor rates increase and skills continue to evaporate. Would be curious to see if this leads to a small amount of well paid and highly productive site crews who still remember how to gang cut

Chronic spillage often shows as rust or melting around draft hoods. Both draft pressure and spillage are measurable and have widely recognized standards

2) Concurrent operation of exhaust ventilation creating a negative pressure around the appliance. 3) Concurrent operation of a ducted HVAC system with return leakage or disconnects around the appliance
