A fun interview with Joe Lstiburek

Andrew Michler at the Inhabitat website has just published a fun interview with Joe Lstiburek. Read it here: INTERVIEW: Building Science Pioneer Dr. Joe Lstiburek.

Warning to Chris Briley and Phil Kaplan: there's some architect-bashing involved. So, all you architects out there -- if you're feeling squeamish today, don't read the interview.

Proper thermostat programming for one room radiant heating?

This question is in regards to a one zone radiant floor and whether I am programming my thermostat correctly.

We have a high efficiency gas fired hot water baseboard system in all rooms save the bath. Here, our plumber installed a radiant system in the ceiling of the basement under a tile floor. We wanted a warm floor in the morning and evening when we take baths/showers.

Do you still tape/seal exterior sheathing with ADA?

The plan is to use the ADA for the interior of the house (Zone 3). The whole exterior of the house will be sheathed with plywood. If using ADA is it still advisable to tape/seal the exterior sheathing?

Do you recommend tape for the exterior plywood or some sort of caulking as it is being installed. In this build the exterior edge of all the plywood will be over a stud (required for shearwalling in this seismic zone). Because the plywood edges will be over studs, it would seem that caulking may work well?

Assuming caulk - is acoustical caulk appropriate?

ICF in place of slab

HI, I am not a builder and I am getting confused. Are these ICF products like Quadlock and AMdeck being used instead of a slab or on top of a slab? I don't want a crawl space or a basement and I want to have decorative concrete floors with radiant heating. I thought that if ICF could be used instead of concrete slab as the foundation, i could have great insulation, places for pipes and wiring, and a decorative concrete overlay with the radiant heat in between. Is this just wrong thinking?

Ducting in slabs & passive solar

I'm looking for research that examines the effects of using ducting in concrete slabs to circulate heat. Specifically, I'm interested if there is any added efficiency in passive solar applications where air is circulated through the slab. My impression is that this technique opens you up to a lot of potential moisture/mould scenarios. Does anyone know of any research that looks at the implications of this technique?

Best source of heat? Looking at ductless heat pumps

I live in Long Beach, Ca., on the ocean. We never need AC, but need heat in the winter.

I removed our old furnace and duct work. Our top unit of duplex is approx. 1,700 sq. feet.

Are ductless heat pumps a good option? We have a wood/gas fireplace that heats main living/dining area. We would probably need two heat pumps. There is no attic. Older 1960s duplex.

THANK YOU for any feedback!
