One more spec from the builder of my recent Sacramento PH Plus project:

For an 8” duct we would use a fintech ADC8
www.supplyhouse.com/Fantech-ADC8...

We would wire two of these on both the supply and exhaust ducts to open in unison when the hood is turned on.

Guaranteed your occupants will have comfort issues with the window opener option. Winter evenings are cold, even in California. If you’re in a humid climate, then summer evenings with an open window will also suck.

Product options for this are certainly a perennial problem. Here are a couple of options I’ve spec’d in past projects:
1. Wall exhaust fan FV-08WQ1 panasonic
Damper FV-GKF32S1 panasonic (have the electrician connect it to the hood switch.)
2. www.swegon.com/products-and...

You’d be much better off adding an automated make-up air damper, in line with the kitchen vent hood. Cheaper overall, and better control for make-up air flow direction.

My how British you’ve become!
[a ‘wobble!!’] 😂😂😂

we've known that shades for solar protection go on the outside of the window for *centuries*

you don't need 20' front yard setbacks for a high quality of life or good neighborhood character

YASSSS! People want something to vote FOR, not against. Now let’s do this for everything, starting with improved resiliency for housing (YES on AB 368) and more transparency in where we are heading. (NO on AB 306.)

So agree. This framing from @nytimes.com is disingenuous. It does not reflect how this bill only applies to urban infill areas, which allows the unspoilt areas of our state to remain.

Who needs right wing media when we have the NYT?!

We’re fighting cultural mythology. Until we decouple the unspoken definition of the ‘American Dream’ as = 1 single family home + 2 cars, we will continue to fight housing battles on all fronts. We need to reinvent or redefine a completely #NewDream.

Honestly don’t know. I outsource my code compliance modeling. (It’s a permit checkbox.) I use PHPP for design guidance instead.

NO. Please see my other post about focusing on manufacturers. [Besides, where has the track record of Dems messaging been particularly effective??? Cough #CuomoFail]

We should be doing this for all electric HVAC equipment. The fact that I can still walk into any appliance showroom in Cali and still buy a gas stove, a gas water heater and a gas furnace is a big #fail of our decarb movement to target manufacturers. 2/2

There are innovative policy moves that result in BIG product transformation. In Canada, BC Govt spent ~$CA400K on competitive subsidies to update window profiles to PH certified levels. 5 BC window companies received ~$40k for technical support. I now import windows from BC for my Cali projects. 1/2

That’s why you target MANUFACTURERS. (If nobody makes gas appliances anymore, these laws are moot.)
Job done. ✅

NO. Please simply ensure gas appliances and equipment are no longer available to purchase!!!! Much better use of our collective time and $$$.

THINK UPSTREAM. Cut off the supply at the source.

If policy simply banned the sale of gas appliances, heavily incentivized installer trainings, & accelerated product innovation in heat pumps, the end user choice becomes a non-discussion.
Let’s stop wasting money on cute end user rebates, events & social messaging and focus efforts upstream? 2/2
