Q: If you replace a water heater, does it have to be inspected in person?
Ted Tiffany
26:32
How do you see the Multi-Family software delay impacting the schedule for the Cost Effectiveness study completion?
Blake Herrschaft
27:39
Bobbi RE: inspections. Great question. This depends on the local Authority Having Jurisdiction (AHJ.) In most cases, yes - a final inspection is required.

The San Jose Reach code appears to amend T24 so that PV ready requirements apply for all nonresidential buildings instead of nonresidential buildings with 3 habitable stories or fewer only. Can you confirm this interpretation?
Alice La Pierre
32:29
My concern is about adding more PV to the grid, without requiring sufficient battery back-up. Right now we still have an ugly "duck curve" that needs correcting. The proposed NEM 3.0 will discourage more PV, even though PV-ready is required by the State.
Jennifer Givens
32:35
For a new or renovated single family home with EV charger(s) and solar, is a 200 amp electrical panel sufficient?
Sharon Block
32:39
Solar ready is already required for High-rise Residential
Tom Kabat
32:55
Benefits of all electric buildings: Safer buildings, Healthier buildings, lower capital cost, no future retrofit cost, fewer utilities to deal with in construction..
Joshua Pierce
38:20
Have a comment regarding economics of new buildings/developments vs retrofits from a benefits standpoint.

Jennifer, based on our analysis - most homes in this region under 2,700 sqft, without a pool or hot tub, can suffice with 100A with a single circuit-share. For example, sharing an EV circuit with a range; whereby while cooking - the EV charging pauses. Example products for circuit sharing include: Dryer Buddy and NeoCharge.
Suzanne Emerson
41:54
For examples of load-sharing equipment (for example, to put induction cooktop as primary and EV charger as secondary on one 50A circuit), see page 69 of Redwood Energy Single Family Retrofit Guide: https://redwoodenergy.net/wp-content/uploads/2021/02/Pocket-Guide-to-All-Electric-Retrofits-of-Single-Family-Homes.pdf

Similar to Farhad’s example, My home has 150 Amp 30 kW capability and my all electric home peak is under 5 kW for the highest 15 minute period of the year

Will decorative appliances such as gas fireplaces be covered under the suggested reach codes?
David Kaneda
50:41
One other benefit of all-electric buildings is the ability to create a microgrid and continue to run a building in the event of a utility power failure. Of course few buildings have battery storage today, but going forward more and more will have it, and EV's will likely be able to provide storage for buildings also.
Beckie Menten (EBCE)

EBCE's commitment is to offer 100% carbon-free power product to all customers by 2030. 🌞
Amélie Besson
55:09
my understanding is that the TA through allelectricdesign.org is only available for projects in PCE and SVCE territory. Is it being expanded to EBCE and other CCAs? And does it cover EV?
Tom Kabat
56:01
For me the easy way to view our “building task” is: We need to no longer install any new fossil machines. Reach Codes are the way to level the playing field so all new and remodeled buildings will participate in preserving climate safety.
Blake Herrschaft
58:31
Amelie - EV yes, It is only for SVCE & PCE territory, but please reach out so that we can discuss - even if your project is out of territory.
Beckie Menten (EBCE)
59:07
Higher *electric rates compared to gas I think Farhad meant to say
Blake Herrschaft
01:02:17
Ellis, regarding fireplaces - please see page 80 of Redwood Energy’s guide for electric options. If the fireplace is purely, I must say that the mist-based fireplaces are shockingly good. Find one to look at in-person. If the fireplace is purely decorative, I would recommend that. However, they do not provide much heat. I am hopeful that we will see a 240V heat supply coupled with an electric mist-fireplace system to provide both visual and thermal ambiance. https://redwoodenergy.net/wp-content/uploads/2021/02/Pocket-Guide-to-All-Electric-Retrofits-of-Single-Family-Homes.pdf

Typo - “if the fireplace is purely decorative”
Suzanne Emerson
01:04:09
Resources for learning more about automatic load management?
Blake Herrschaft
01:07:16
Suzanne, Chargepoint does a good job here: https://www.chargepoint.com/products/power-management-faq. Please also reach out to us via the tech assistance offering if it is project specific. https://docs.google.com/forms/d/e/1FAIpQLSeFU3EYoPfqTSlsHA6ZjMjd8XWhGN-WT-dmrwCykSBBs-9Ucw/viewform?usp=send_form

First tier gas was about $2.08 /therm in January.
Ted Tiffany
01:13:10
David Kaneda, I think we need to do a lot of work on traditional electrical sizing rules for new construction and processes for existing buildings. The fact that we have one major jurisdiction preventing load sharing devices (without justified reason) is telling of the work we need to do on electrical peak load sizing for service.
Alice La Pierre
01:18:27
Current PG&ENatural Gas Winter Rates (Commercial) are $1.77809 per Therm for baseline use, as of February 2022. For Residential, Current rates are $2.07001/Therm for baseline. Natural gas is not cheap.
Blake Herrschaft
01:19:08
Does that include Public Purpose Charge?
Alice La Pierre
01:19:32
Report an OutagePrint Page Email PageBefore calling PG&E about a power outage, check to see if others in your area are affected. This would confirm if an outage has occurred in just your location or within the neighborhood area. If only your location is without power, check circuit breakers and/or fuse boxes to see if the problem is limited to your electric system. After performing these steps, call PG&E's Business Customer Service Center at 1-800-468-4743, Monday through Friday between 7:00 a.m. and 7:30 p.m. and Saturday between 7:00 a.m. and 4:30 p.m. to report and check the status of your outage.Say “Outages” then confirm selection with “yes.”Say either “electric” or “gas” depending on the source of the outage.Say your phone number associated with your account. If you do not know, say “I don’t know.”Yes, that is the total baseline cost per Therm.
Alice La Pierre
01:19:43
Sorry about that.
Tom Kabat
01:19:45
@ Blake Yes includes all components in the gas rate.
Blake Herrschaft
01:19:59
Thanks both!
Alice La Pierre
01:23:11
If you install the MOTOR for the range hood in the attic, rather than just over the range, it will be a lot quieter.
Amélie Besson
01:24:43
just to make sure, Residential = Single and Multi Family?
Blake Herrschaft
01:25:38
Alice, I personally think that should be a code mandate for both IAQ and IEQ purposes
Blake Herrschaft
01:26:42
Amélie, yes. For which specific code requirement?
Amélie Besson
01:27:04
the prescriptive battery storage
Jackeline
01:27:48
Any religious exception?
Tom Kabat
01:28:13
I suggest also restricting (prohibiting) any gas pipe upsizing. This will help prevent gas tankless water heater proliferation.
Jackeline
01:28:46
We got a request for gas range requires for religious purposes
Tom Kabat
01:33:09
Propane would be a common way to retain fire in a range.

Wish: When 75% or more of an HVAC system is new or replaced, the new or replaced HVAC system shall be all-electric.
David Kaneda
01:52:22
One big issue with current electric codes is that they cause engineers to massively oversize electrical systems. Actual maximum demand numbers I have seen are often about 1/3 of the size of the service. It would be really valuable to develop some design methodology or hardware/controls to allow designs to get closer to the actual expected demand, specially related to existing buildings.
Alice La Pierre
01:52:55
My concern is that the electrification-only leaves a lot of potential energy savings on the table--without including building envelope improvements, including draft sealing, wall, floor and attic insulation ABOVE code minimums, and the use of high performance windows and doors, the energy cost savings for moving to electrification is much lower. Also, there is no thermal comfort improvement, which is what the customers "feel."
Leila Ansari
01:56:54
Wish: That some jurisdictions allow more lithium ion battery storage capacity. We're restricted to only 26 kWh. Each Tesla Powerwall is 13.5 kWh :(
Alice La Pierre
01:57:25
Existing buildings

Are there incentives for induction cooking ranges? I'm guessing the electrical requirements might also be a stumbling block converting from gas to electric.
Phillip Kobernick

https://www.bayren.org/homeowners/induction-cooktops
Tom Kabat
02:00:24
I find that a 3 ton (36000 but ) or lower heat pumps can work on typical furnace ducts. And then instead of trying to deliver 60,000 Btu morning thermal power delivery, we just have the programmable thermostat start up an hour earlier and it still meets the comfort requirement while operating at a lower thermal power.
Eryn Kim
02:01:13
Sharon, EBCE is offering induction cooking rebates for commercial, community, municipal kitchens (non-residential). You can find more information here: https://ebce.org/commercial-kitchens/
Eryn Kim
02:01:39
Above rebate is only eligible for EBCE customers.
Suzanne Emerson
02:02:44
Wish: Existing Single-Family: Cooking Equipment: Additions: Kitchens in additions shall be all-electric. Remodels: When a kitchen is being substantially remodeled or relocated, systems using gas or propane cooking equipment shall be Electric Cooktop Ready as provided in Energy Code section 150.0(u).
Lucas Morton
02:02:49
@tom. this may still run afoul of fan watt draw and coolong airflow requirements in part 6. it's not that it couldn't work in practice, but it may not always pass the requisite testing
Anais Engel
02:05:32
Will you be sending these slides out? these links are so helpful!
Mayra Vega
02:06:42
Yes we will send out the slide deck

It looks like the meeting is being recorded - will we have access to that as well?
Blake Herrschaft
02:07:47
Yes
Alice La Pierre
02:08:20
Can you record the chat, please? Lots of good info here!
Amélie Besson
02:08:47
Do you have a list of cities/counties already interested/working on 2022 Reach Codes?
Suzanne Emerson
02:09:08
I'll send you my long-format Wish List.
Farhad Farahmand

@Alice the chat is being recorded as well
zoe elizabeth
02:11:52
@Ellis are your clients commercial, single-family, or others? What are you hearing?
Ellis Schoichet
02:12:40
The proposed surcharge on residential solar is discouraging clients from installing solar.
Tom Kabat
02:13:31
@Zoe, Allowing any gas devices to be installed or replaced when they burn out will put us over the Paris 2 Degree climate damage level. So we need to look at how to improve the triggers to capture more opportunities (avoid more stranding )
Farhad Farahmand
02:13:54
Ellis: The discussion around NEM3.0 has been deferred for several months at the state level, since the recent CPUC proposal has been perceived as problematic. The surcharge specifics are likely to change.
Phillip Kobernick
02:14:15
Yes, definitely. And PCE is testing telematics-based managed charging (not smart chargers needed)
Phillip Kobernick
02:14:24
no*
Anais Engel
02:15:40
this was excellent and easily digestible - thank you so much!
