We've been lucky in Southern California this summer. So far, the temperatures have been relatively mild. But, the last week or so, it's been hot enough to weigh in on the effectiveness of our cellulose attic insulation. And my decision is... it's great!

During the day, the house is noticeably cooler than the outdoors. I haven't found myself sweating while doing light cleaning on a weekend afternoon. And when I come into the house after working in the garden, it's feels nice and cool--not stuffy.

That's all great, but the true benefit of the insulation comes at night. Previously, the house would feel warm and stuffy in the evenings. Now, it's just as cool as it is outdoors. On previous summer evenings, we would sit in the living room with as few items of clothing on as possible, trying not to sweat. Now, I wear thin sweatpants when relaxing after work. It's that much cooler!

My final piece of evidence is this: We have yet to dig out window air conditioner out of the garage. The insulation is working so well that our bedroom is cool enough to sleep in with just a few open windows and a ceiling fan. The cheapskate in me is delighted by how much we're saving on our energy bills.

So, with all this evidence, I can definitely recommend that everyone upgrade their attic insulation to R-30. The insulation, along with the solar attic fan and our indoor ceiling fans, has really made living in Los Angeles without central air conditioning easy. And even if you do have central air, I'm sure your energy bills will go way down with the new insulation.

After an unusually damp and overcast June, I think we've finally entered prime line-drying season here in Southern California. I especially like drying sheets this way. While they take ages in the electric drier, sheets dry so quickly and smell so nice when hung in the sun. Plus, who doesn't enjoy saving money and electricity?

Yesterday I had to work from home, so I decided to take advantage of that fact and have the attic insulated. This is something we've been planning for a while, and I wanted to get it done before the weather became too hot. So, I called up Everguard Home Insulation and made an appointment to have cellulose insulation blown into the attic.

Everguard was great. They showed up as scheduled, after calling to let me know they were on the way, and communicated clearly about what they were planning to do. They worked quickly and cleanly and got our 950 ft2 attic filled in about 45 minutes. Impressive.

The fluff blob above is a small chunk of the cellulose insulation that escaped from a roof vent. As you can see, it's basically fluffy, ground-up newspaper and cardboard fibers. To make it fire retardant, the cellulose is treated with boric acid. Unlike fiberglass, cellulose is recycled, environmentally friendly and non-toxic. So, it's perfect for green-living homeowners, like us.

And for frugal homeowners, the Southern California Gas Company offers a rebate of 15 cents per ft2. So we'll actually get a check for $142.50 after we submit our paperwork. Plus, there's a 2009 federal energy efficiency tax credit for 30% of the cost. So, we'll get even more money back when we file our tax returns. With all those incentives, I can't imagine not insulating the attic.

The new insulation, combined with some old, compressed and ratty fiberglass that was already up there, brings our attic insulation level up to R-38. This should hopefully make a big difference in how hot it gets inside the house this summer, especially when combined with new wall insulation, new ceiling fans and our solar attic fan.

I've said it before and I'll say it again, Who needs air conditioning! (Check back with me in July for the verdict on that one.)

It's always cool to see new solar products appear on the market, and it's even better when they get cheap enough for regular people to buy. Last year, I searched around to see if I could find any solar-powered light strings to decorate the house for the holidays, but I didn't really find anything. This year, solar light strings were available all over the Internet. Delighted, I decided to try them out.

I got two 50-light strings of white lights from Plow & Hearth. They seemed to have the best price on what I wanted. When they arrived, I pulled them out of the box, let the solar panel charge for a day and then wrapped them on two plants in the front yard that grow in a bit of a cone shape.

When you set them up, you wrap your lights where you want them and then stake the small solar panel in the ground nearby.





So far, I'd say I'm fairly happy with them. The solar lights have a light sensor built in, so they turn on automatically when it gets dark. When they light up, they look nice--although not as bright as traditional plug in lights--and the solar battery life seems fairly long. They stay lit for around 4 hours.



The lights are nice, but not perfect. I have noticed two issues:

1) It takes some trial and error to find the perfect place to put the solar panel. I have had to move mine several times when the lights weren't sufficiently charged by the end of the day. And, of course, if you live in a place that actually gets gray and gloomy in the winter (as opposed to sunny Los Angeles), I'm not sure how well the panel would charge. Although, if you live somewhere with snow and sun, I imagine there would be enough reflection off the snow to charge the panel right up.

2) The light sensor is very sensitive. The street light across the street, our porch light and even my car headlights have caused the lights to turn off. I think I have the sensor turned in a way to minimize that problem, but it is a bit annoying. If you live out in the country, you wouldn't have this issue. But, in a place like Los Angeles, it's pretty hard to find a place that's completely dark.

Overall, though, I'm glad I got them. Because you don't have to plug the lights in anywhere, there are no annoying extension cords to deal with, and your light decorating options aren't limited to where your outlets are. Plus, they cost nothing to operate, and with their LED bulbs, they should last for many Christmases to come.

Nothing says "party" on a Saturday night like installing denim insulation, and that's exactly what Dakota and I did last weekend. Jealous? Thought so. Actually, it was kind of fun (in a way) and made us feel like some actual progress was being made on our slow and steady kitchen remodel.

As I mentioned in a previous post, I was able to find a local supplier of UltraTouch Natural Cotton Fiber Insulation in the Los Angeles area. So, last Saturday night, we ripped open the roll of insulation and laid it out on the floor to fluff up. It comes in long strips and basically looks like a long rectangle of dryer lint.

Here's Nigel demonstrating how safe and non-toxic UltraTouch is.



The UltraTouch website uses babies and small children to make this same point, but I think Nigel should become their new spokesmodel. I mean, look how excited he is to be resting on layers of earth-friendly insulation.

Nigel also decided to help us install the insulation. Here he is weighing down a piece while Dakota cuts it to fit between some studs.



I had read that denim insulation can be difficult to cut, but we just used an old saw and a box cutter and did fine. I guess our edges weren't particularly smooth, but since the insulation will be hidden inside the walls, I'm not too worried about it. Overall, installing the UltraTouch was pretty darn easy. It took us about an hour and was so foolproof that I was able to help.



Up to now, the kitchen work has either involved heavy demolition skills or woodworking skills, both of which I lack. But I think we may be heading into a stage in which I might actually be able to do more than lend moral support and research skills. I'm glad, because Dakota has been working exceptionally hard.

Here's one kitchen wall, nicely insulated.



Since the kitchen is on a back, unshaded corner of the house, it really gets blasted by the sun in the summer. The addition of the insulation, plus ceiling fans and energy-efficient windows will hopefully make a big difference when the weather gets hot again.

Those of you who know me know that Dakota and I have been just about to start our kitchen remodel for, hmmm, maybe 2 years. In fact, the current kitchen has been in a state of partial demolition for at least that long. Various considerations have kept us from actually making real progress, but, starting in September, we will be really and truly actively remodeling our kitchen. Really!

In fact, today we took another preparatory step and picked up our new dishwasher from the appliance warehouse. Our current dishwasher is fairly large and the kind that you roll over to the sink on casters when you need to do a wash. We wanted to get a built-in washer, and we also needed one that was more compact so that it would fit in a spot next to the sink.

First, we looked on the Flex Your Power website to see what rebates might be available (looks like a $30 mail-in rebate from SoCalGas is what we'd get). Next, I headed over to the Energy Star website to find out what compact dishwasher models were energy and water-efficient enough to qualify. They have a nice search function on the Energy Star site, so it was easy to find what I was looking for.

After poking around a bit on the Internet, we decided on a Fisher & Paykel model. It's a drawer-style dishwasher with two washing compartments that each hold six place settings. You can choose to run one or both drawers, depending on what you need to wash. Each drawer uses less than 2 gallons of water per wash cycle, and it has a delay-cycle function, so we can wash dishes in the middle of the night when other power use is low.

We got the model that allows you to make your own custom fronts, so Dakota will make fronts for the dishwasher drawers to match our cabinets. You'll barely be able to tell the dishwasher is there. And, it'll be right next to the sink for easy loading.

This dishwasher wasn't cheap (although we found a good deal), but since Dakota is doing all the labor himself, and because we have aquired some other materials as gifts or trades, we won't have to spend a lot of money on anything else.

If all goes according to plan, the only other major expense, besides the wood for the cabinets, will be a new faucet. We analized that situation today, and I think we're leaning towards something from a company called Hansgrohe. I'll let you know what we decide.

Who needs air conditioning? Well... maybe us, but central air is not going to be installed in our little house for quite a few years. It's just too expensive. Sometimes little problems like this are good, because they lead you to find interesting and smart solutions. For example, a solar attic fan.

I didn't know much about attic fans until recently, but it seemed like a good solution for one of our major heat problems: hot air from the attic dropping down into the house on summer nights and turning our house into an oven. Attic fans help suck hot air out of the attic and keep cooler air cycling through. Getting a solar attic fan means we don't have to hook it up to our electrical system, saving us money and, you know, saving the planet.

Our solar attic fan is made by Solatube. It doesn't have a thermostat, so it just automatically turns on when the sun hits it. The stronger the sunlight, the faster it spins. There are other varieties that are a bit more expensive and have a thermostat, but we felt that it was better to get a simpler system with less parts that might break. This fan is really simple, and comes with a 5-year warranty for the solar panel. We bought it from a small distributor in Sherman Oaks.

The attic fan was quite easy for Dakota to install. He just cut a circular hole in the roof, slipped the flashing under the shingles and screwed it all down. I'd say the whole project took him about 45 minutes last Monday.


Dakota installed the fan on the front of the house, because that part of the roof gets the most afternoon sun. I was worried it would look ugly or weird, but the fan has a really low profile, so you can barely see it. It's also completely silent. I don't even know it's there. Of course, I hope I notice its effects once the weather starts getting hotter.

Good news. The check from Los Angeles DWP arrived yesterday. We got a $200 rebate on our new washer/drier and a $50 rebate on the air conditioning unit. It really pays to be resource conscious, especially this year when it's barely rained a drop.

Hopefully, by the time we start home renovations, we can take advantage of other incentives to build sustainably, like solar energy grants and energy efficient mortgages.
