I hear they have a lot of "net zero" housing in San Fran, call um "tent cities". How about we make some Adobe Huts. They're real cute,make a lot of people fell right at home. Hmmm? I think I'm getting politcal here, sorry.
 
Not paying your electric bill and having your service disconnected:D
Setting all variables to zero is what my favorite calculus prof would call the "uninteresting solution to the equation". No partial credit. :D
 
yup. i got a call from a contractor today, the inspector
turned him down. no certification, and he didn't have daylighting
controls in the primary area.
there was *one* two tube T-8 fixture in the primary zone.
66 watts. daylighting controls not needed under 120 watts
connected load for downlighting.

he was ready to go spend $2k for nLight controls, to dim one fixture.
not necessary. will write magic letter with certification, and sprinkle
electron dust over the time clock.


the learning curve on this stuff is painful. another guy just got his
first demand for certification docs. then we find out he has a 13,000
sq ft floor of a building, done in wattstopper. stand alone room controls.

oops. he needs to add a backbone interlinking all those individual controllers, for demand response..... $20,000 later......

with all the frothy BS i spew on here, the one really important
piece of info i can offer to folks contracting in the golden state,
is not to get creative with lighting packages. don't substitute
luminares or controls without engineering approval. "value engineering"
and design builds in commercial, without a very clear understanding
of the requirements, and a very clear path to certification at the end of
the job is really playing with the third rail of contracting here today.

That's incredible. And he'll save $4 in energy per year. Payback in 5,000 years.

Don't blame the regulation for the designer's failure. The cost for demand response would certainly have been less had it been in the original design, rather than installed as a retrofit.

Thank you for that clarification. :thumbsup:

it's all good. i got a request for tomorrow for a cert for a 500 room hotel
remodel in LA, they are 60% done, and found they have to have the magic paper.

the convention rooms are partly done. they are on delta 8 on the lighting plans.
the engineer of record is in ohio. they don't do this stuff there.

this.... will be interesting.
