The Quarky Engineer

Lots of new things underway – With that ridiculous water tank done, the storm water filter garden is being built. Hole, liner, rock, and 25 yards of really nice soil plus 78 specific plants picked by the city. Yea. All of this to protect the soil from rain falling from the sky.

Cedar walls/ceiling for the vault, more paint on the outside, drywall delivered. We installed two temporary 20kw furnaces today to help heat and dry out the house.. A good way to break in the meter! We are also going to install the two infratech heaters, and those guys are 6kw each. If I can get a few Teslas on the chargers we can see how much that transformer can really dish out. It is rated for 75kw, but no doubt in this cold weather it can do a lot more.

Drywall starts tomorrow as well as a bunch of interior trim work, and of course more exterior painting and some cedar ceiling work.

I need to select some light bulbs for the new house.. I checked today and there are 230 indoor can lights, 30 external can lights, and 38 indoor shop/garage fixture lights. (plus probably 30 other regular fixtures, but those are something Kristin is dealing wtih).

For the indoor can lights the fixtures are 6′ cans, so they can fit a variety of options. I would tend to do the recesssed lighting trim, which is a single trim+led unit (not a bulb that unscrews). This is pretty common in very new houses, especially if you want a sealed light look.

Within this variety there are two key variables –

Brightness (~600,~800 or ~1100 lumens, which corresponds with ~ 75,100,150 watt equivalents)

Color Temperature – 2700, 3000, 4000, 5000K. A typical old school incandescent light is in the 2700K range.

A typical LED fixture in 2700K, 660 lumens, is around $4 in quantity.

There are LED fixtures that have a selectable switch on them you can set at install (or change) that gives you 4 color temps. Those fixtures are around $25 each.

There are also LED fixtures that have remote selectable color temp (via zigbee for instance), and they are around the same cost ($25 each).

Any comments/wisdom on color temp choice? I would tend toward 3K for most things, and if there were a location I might want the user adjustable color temp it would be the master. That would facilitate the color temp changing in the evening and morning with the other automation tasks.

As for the brightness, I need to do some light mapping to see what will work best. If every bulb was an 800-900 lumen bulb that would be around 3kW of power (~ 12.1w each). Consider that if these were old school 100w bulbs that would be 26kw!

The outdoor cans are a little different. For those I will do some kind of controllable RGBW bulbs.

81 Z-Wave switches ready to install! I am using these Homeseer WD-200+s, which had individually addressable RGB leds.

A small update – The storm water tank is completed and buried, with the filter planting area being the last thing needed.

The ceiling for the outside rear deck is getting installed, and you can see the spots for the Infratech heaters. 12,000 watts of juice.

The side grass is also starting to come in.
