Does anyone know if there is a manufacturer that makes an energy efficient, dual HVAC/ ventilation system that would satisfy both of my needs and eliminate the need for 2 duct systems?

I'm planning a moderate size home in SoCal in a semi-desert climate with adequate thermal mass. The home will have a tight envelope and my understanding is that some sort of ventilation system with separate duct work is required.

I was planning on an air-source heat pump to meet heating and cooling needs, but this will only be used in the summer and winter months mostly.

Mount outdoor unit on the wall or on the ground?

I am close to installing 3 fujitsu mini split units at our home under construction. Two outdoor units will be installed near each other, with the third installed in a different area of the house. The HVAC installer asked if I wanted to mount them on the wall or on the ground. I can't decide which I would prefer. Any thoughts on the pros and cons of each?

I live in central KY, zone 4A. We don't get much deep snow around here, maybe once every 10-20 years.

New house build, SIPs?

New member here, we are planning to build a new house this summer and I'm exploring my options for wall systems. I plan to do the framing myself. House will be roughly 2500 sqft in Ottawa, Ontario Canada. Not the coldest place to build but not far off, and just for kicks it gets pretty hot and fairly humid here in summer as well.

Help identifying roof shingles

Hi - Can anyone provide insight into what type of roof shingles are used in the two attached pictures? I like how they present thick horizontal lines, but I can't find any shingle manufacturer websites with similar looks.  I think both of these houses were in Europe somewhere.

Installation of a firebox in a very old stone fireplace that is on an external stone wall and is very damp.

Do I install a vapour barrier first and then rock wool or ceramic wool with aluminium foil in order to insulate the interior of the existing fireplace? would I use similar techniques to the techniques of shower construction e.g.. backboard etc?

Green building concepts and expanded polystyrene

Hi, Thank you for adding me to this professional community. Expanded polystyrene and green concepts.

Hi, I am expecting experts advice on the Green side of expanded polystyrene (EPS) building materials. Currently, I am working here in the Middle East in a construction company.
Most of the works here are completed with one or other forms of polystyrene or other Styro varients. I need to know more about the Green concepts behind expanded polystyrene building materials.
