Power bill update

Wednesday, May 19th, 2010

Now that we have been in the house for 10 months, we thought it was time to post our monthly power bills:

July 2009 $55
Aug 2009 $52
Sept 2009 $42
Oct 2009 $63
Nov 2009 $90
Dec 2009 $123
Jan 2010 $98
Feb 2010 $90
Mar 2010 $61
Apr 2010 $46

As you can see, we’ve been able to keep the bills pretty low. To contextualize these bills, it is helpful to know what draws electricity in the home:
- geothermal HVAC
- washer
- dryer (only when it is not sunny)
- dishwasher
- water heater (only when it is cloudy and the solar thermal is not working)
- disposal
- pumps for the rainwater collection system
- household appliances (hair dryer, toaster, water kettle, computers, TV)
- ceiling fans
- lights (all equipped with flourescent bulbs)

We also have more or less stuck with the default EnergyStart thermostat settings for the geothermal, which means

Heating;
68 degrees from 6:30am to 8am and 5pm to 10pm
62 degrees at all other times

Cooling
78 degrees from 6:30am to 8am and 5pm to 10pm
85 degrees at all other times

The house itself is two stories and covers about 1800 square feet. As previous posts indicated, the house was also newly insulated with spray foam insulation in all exterior walls on both floors and 12″ of cellulose on the attic floor. Spray foam was not used along the roof line. We also had new double-pane Integrity windows installed throughout the house (more on those in another post). These insulating features have no doubt played a big role in keeping our energy bill down, too.

Unfortunately, we do not have any real points of comparison because the house did not have heat or air when we moved in.

Siding a success

Thursday, April 29th, 2010

As an earlier post indicated, we decided to have all the old pine siding removed in order to install spray foam insulation around the entire house. That step of the process went smoothly, but we were concerned that the old siding would not be up to the task of being put back on the house. After lying stacked up in the backyard all summer and beginning to look a bit forlorn, the siding’s time had come. We started the process by priming the one side of the siding that had been exposed to the elements for those many years. Then, the siding was put back up on the house over the spray foam insulation with the primed side facing in. That left the unprimed side - the side that had been facing in for the life of the house - facing out and ready to be primed and painted itself. Our concerns about the siding becoming warped were unfounded; we were able to re-use just about all the siding and needed new siding on just one small exterior wall to make up for the few pieces that had cracked or were too worn to re-use. In the end, all our discussions and research about how best to insulate the house (drill & fill from the outside; remove plaster walls on the inside and spray in insulation; remove siding and replace with new siding or Hardiplank), we’re very happy with the decision to have the siding removed. We got the spray foam insulation we wanted and we were able to keep the great, old siding that you just can’t find anymore. We’re even fortunate to have a few pieces of siding left over that we’re hoping to turn into bookcases and shoe racks.

Solar thermal knows no cold

Thursday, April 29th, 2010

We’re a bit behind on our posts, but we’ll try to get back on track with this one from our winter experience with our solar thermal unit. The Velux system that we have has a nice feature that lets you read the temperature of the collectors on a display in the systems room. During the cold snap earlier this year when daytime temps barely rose above freezing yet the sun was shining brightly, the collectors were still registering temps in the 145 degree range, i.e., more than enough heat to maintain the 120 degrees that we have the water heater thermostat set at. Even when the daytime temps are low, the collectors are still able to harness the heat of the winter sun.

Green floor finishing

Sunday, August 2nd, 2009

Everyone these day has a green product or story, but what really makes it green?  For flooring, I have been working with some of my vendors to green their process.  One in particular has done a great job with the task at hand.

Here is post that I had on our other blog about flooring: green flooring

On Lake Claire LEED we were able to save most of the flooring in the house and where we had to refinish the floors we used zero VOC finishes in order to preserve indoor air quality.

What this was then and now will be

This is the dining room wall being carefully taken apart.

This is the dining room wall taken apart and collected into tidy piles of lathes and studs and plaster.

This is a pile of chunked concrete removed from the uneven otherwise mostly red clay basement floor. It has been hauled away and ground into gravel.

chunked

This is the gravel used to level the basement floor before the concrete is poured.

Now all of these posts are gone from the basement, but they are still around, waiting to be milled into wood for a table and a slatted wall, which will be held together with nails pulled from the lathes.

These are doors, removed from the walls that were taken down. And they will be doors again in the basement or elsewhere upstairs.

This is old asbestos covered ductwork, now properly disposed of, never to be heard from again.

Hey, you can’t reuse everything, but we are having fun trying.

It’s like taking keys off your keychain…

Wednesday, April 1st, 2009

keys1

Many years ago a friend remarked that a person’s keychain could tell a lot about him, specifically that the more keys the chain holds, the more complicated one’s life is. As we sat around the other night revisiting why it was in the first place that we wanted to build an eco-house, as we named the idea many years ago, I was reminded of this sentiment by my husband. “It’s like taking keys off your keychain,” he said. To simplify things and not create waste or use more than you need to is a main force driving our thought process concerning the renovation of our old bungalow. If the sun is there, use it to heat your water or power your appliances. If the ground will offer up its constant temperature efficiently, then harvest it to heat and cool your house. Take that rainwater and at least use it to water your plants, and if you can, use it to wash your clothes or even drink! It is not quite as simple as that, I know, but we are trying to do as much as we can along these lines. I was thinking about these ideas this morning, as my husband rode off to work on his bike in the rain. Uncomplicated self-propulsion is an efficient and beautiful thing.

“Going for Gold”- may get Platinum

Saturday, March 28th, 2009

When we last sat down to look at the points for Lake Claire LEED on the LEED for Homes worksheet we added them up and it looked like we should get at least LEED Gold which is very good!  However, we reviewed a couple of areas with the homeowners last week and it looks like Platinum is a possibility.  The house was going to be very efficient so there was not much more that we could do there, so we looked to the landscaping.  Since we are looking to use native plants, rain harvesting, and smart planting we should get enough points in Site Development to push us into the Platinum point range.

Towards the end of the project, we will post the complete point sheet so we can see how we managed the project to be more sustainable.
