An Educational Morning

 I've been spending a lot of time on PSE's website (the power company), keeping track of rebates and things, and rather on a whim I scheduled a HomePrint assessment a few days ago, because, hey, I've been having trouble with decisions, and more information is good, and it was free.

I was a bit worried that it wouldn't be useful, since there are things about my house I *know* are bad that I can't fix, like the minimal wall insulation, and other things I'm planning to fix but haven't gotten to yet. (I was also afraid the guy would see my house and go 'how can you live in such filth and squalor!' but that didn't happen). It was actually pretty interesting, though, and, hey, I got a bunch of free CFLs, and free stuff is cool. 

And I learned things! I even learned things I can do immediately, and things I can work into my remodel, and potentially a way to get the benefit of furring out the wall without actually doing all the tedious work with furring strips -- all of which is awesome! 

From top to bottom --
  1. I need to unkludge the bathroom fan vent that dad I kludged because it was raining. Currently the very nice bathroom fan takes up one of the roof vents, and the roof could really use more ventilation. More roof vents or a ridge vent would be good in future.
  2. I need to replace the cardboard baffles in the attic, not just make new ones for the new area, because they've fallen from the right position and are actually hindering things. That job takes zero money, but it'll be miserable to actually do. NOT looking forward to it. Ick.
  3. In related news, he suggested a 2x4 two instead of the 2' OSB I have up there to make it easy to get through the attic, since the OSB seriously reduces the insulation in the areas it's in. I knew it was an issue; 2x4s are a decent solution, I suppose. I'll probably put up more than one, though.
  4. vent hood for the oven, for CO and moisture reasons. Well, that's not news. What is cool is that the guy suggested moving the old bathroom fan -- which has been replaced but not removed -- into the kitchen in the interim between now and actually shelling out for a vent hood and possibly moving the stove, which is a nice idea.
  5. Should do lots of caulking for air sealing around joints and electrical fittings and things.
  6. advice on water heaters. Apparently a gas storage heater (like I'd been planning) is a bad idea in a conditioned space, and I should either look at gas tankless, condensing gas (a fancy storage heater), or an electric heat pump water heater. Back to the drawing board -- but good to know!
  7. The walls are a problem, and will probably always be a problem. :( They're very poorly insulated, but since they do have some insulation, they're not candidates for drill and fill. Poo. Only way around that is to reside the house, and that's not in the cards.
  8. The floor is awesome! Not only is it well insulated (which I knew), but there's an air barrier between the insulation and the floor (which is 2x6 boards, not sheet stock, so there are lots of air gaps). Also, I managed to keep Calliope from following him down into the crawlspace. Yay!

This is all part of the "Owning your own home" syndrome...

We have a continuous flow gas hot water system which is very useful for households with lots of folk, and while we only have me & $wife in residence, we do occasionally get smothered in offspring with/without hangers on and it's comforting to know there'll still be hot water for the last shower...

I'm currently working my way through substituting LED lamps for CFL for two reasons; 1) they're cheaper to run, and 2) they are more reliable in the long run (switching them on and off in short repeated cycles destroys CFLs but not LEDs so far as I can tell). The last set of LEDs I bought at $NZ25 each say 30,000 hours anticipated life. Great for hall lights that tend to stay on all day and night ($wife was born in a tent and seems to not know how to turn off lights most of the time). I have a 2W LED lamp at the top of the internal stairs which never gets turned off.

An interesting thing I noticed about the LED lamps is the presence of a switched mode power supply in the globe which will run on 100-240VAC - so the same device for US/Japan (110/120) and the rest of the world (220-240) which improves the economies of scale for the product.

An aside: the wobbles continue apace...

LED lights

CFL globes here come in two kinds, Warm White (3000K) and Cool White (6500K). The numbers are the colour temperatures of the light.

So far I've only seen warm white LED globes, which probably won't give you high colour accuracy, as I suspect the cool white colour temp is the more accurate for midday sun colour. I read (in IEEE Spectrum iirc) that our use of cool white in offices all day leads to disrupted circadian rhythms as the mind is attuned to a more yellow colour morning and evening with the bright bluer colour associated with midday sun, hence the body expects to wake up to warm white, peak activity with cool white, and wind down in the late afternoon with warm white again. The article went on to point out that technology is rapidly approaching the point where the colour temp of artificial light can be programmed to reflect the natural changes in colour throughout the day leading to a better balance in life. LEDs are really marvellous things in that respect.

I read on FB a quote from Einstein when he said The really important discoveries in science don't begin with "Eureka!" but with "that's funny".

LEDs being a case in point - the guy who discovered the LED effect had no idea what use it would be, but saw it as a solution looking for a problem to solve. And look where it's got to now!!
