Energy Efficient Lighting Gallery / Tour / Tutorial or Video

I am looking for some visuals to help design energy efficient lighting for a new home (and persuade others in the project!). Can anyone point me to some good resources for reviewing some options for the various types of lighting and rooms? I would like to see some good photos / video of installed lighting - ideally not focussed on the modern look, but something more traditional. Ideally it would be good to have the model and brands of the fixtures pictured. Are there any online design tools that allow one to play with the lighting options?

Low slope roof with a PERSIST / REMOTE house? Possibly using insulated metal panels instead of steel deck

Toronto, Climate Zone 6.

Follow-on to my last question about insulated metal panels in a PERSIST wall system, I am wondering about roof. My understanding is that one of the differences between REMOTE and PERSIST is that REMOTE utilizes a vented attic.

For a low slope (2 degree) flat roof, what would be recommended? Do I adopt PERSIST wall structure (modified with insulated metal panels instead of exterior foam board) with the addition of a top layer membrane and sheathing?

ii) MemBrain
iii) 2x6 framing (5.5")

Breaking thermal bridge of dry stacked wall from foundation

I planning to build a house with a basement soon, and looking into dry stacked concrete block walls with exterior foam board insulation. I'm looking into dry stacked wall technique due to cost, durability, thermal mass, and DIY friendliness.

The issue I can't seem to wrap my head around though is the connection between the foundation/footers and block wall. It seems to me that this would be a huge thermal bridge, and since concrete only has an r-value of <1, I would assume that all the heat capacity of the concrete would quickly be sapped down through the footings.

Insulating wood floor in a pole shed

I have a 24x36 dirt floor, uninsulated, open, metal sided and roofed pole shed that is currently being used for hay and junk storage.

I am planning to turn the pole shed into a wood working shop by adding all the obvious upgrades, but I am vacillating between concrete and wood for the floor.

My current shop has concrete, which is fine, but I have always been drawn to the idea of a wood floor for a wood shop.

If I go with a wood floor then it will be on short piers over a crawlspace.

Pesticide treated rigid foam

I am fairly close to a Cellofoam plant (www.cellofoam.com) and can buy 25 pound, one inch rigid XPS for my slab edge insulation that has been treated with Preventol insecticide. I'm not wild about using insecticides anywhere, but this seems to be one of those situations where it is worth the risk. Zone 3 is a pretty tough area for termites and carpenter ants, and I'd like to keep them away from my framing.

Clarify the ASHRAE 62.2 ventilation rate spec.

It says 1cfm per 100 square feet of occupiable space and 7.5cfm per occupant
My question: for how many minutes? ... 1cfm for an hour, 6 hours, all day?
