Well hello, welcome aboard!

Just had our house run through an energy audit and improvements... reduced 12tons of CO2/year and NatGas reduced by a 1/3.

What have you done?

 

As my wife remodeled every room in our house, I added energy savings as as I could
two A/C units 20 SEER
'on demand' water heater
3 LED lights where they need to run forever
72 CFL lights
T8 tubes replace T12 Fluorescent light bulbs
additional Attic insulation
additional insulation on all outside walls
double pane low E gas windows
Solar/Hybrid Attic fans on south side, low Amperage attic fan on north side and garage
Reflective shingles to reduce A/C use
Gas Dryer rather than Electric
Front load washer leaves clothes dryer

Unlike Spiderman, I have no idea how much this reduces my carbon foot print, but every month since I started, my energy bill has been smaller than 12 months ago.

 

If you don't mind me asking, how much were the 20 seer ac units? What brand are they? Did you upgrade the whole hvac system or just the ac unit?

 

I protect land from development, restore natural habitat and plant thousands upon thousands of native plants.

 

Actually, it was easy. That State of Alaska has a program that will actually pay for energy efficiency upgrades and the audit itself! We just scheduled an audit, the auditor came in and ran tests and sat down with us discussing all the things we could do and the points associated with the improvements. The largest point increase was replacing our old furnace (~84 to 96% eff.). That along with insulating the crawlspace walls, sealing walls and outlets, replaced most of the windows, and new garage door came to about 11.5K and we got reimbursed 7.5K. What a blessing. Anyone can apply and can get up to max of 10K.

The whole house HVAC was a 5 ton American Standard and including labor was about $13,000 The unit it replaced was over 30 years old.

Hello!

I'm new too and don't have a prius but I love reading what people have done to them

 

I'm a bit of a green nut, though I am not a believer that carbon dioxide is the evil that some make it out to be. It's what my beloved plants need to perform photosynthesis.

I'm a composting fool, and between the worm compost operation, the many outdoor windrow and upright compost bins and the recycling, our household trash amounts to a couple cubic feet a week, uncompressed.

We also ripped out most of the drywall in our house to remove the inadequate vintage 1930s "balsam wool" insulation and some fiberglass. We had closed-cell insulating foam applied at R-6.8 per inch, plus it's an air barrier so it seals out all drafts. Now the second floor of the house really doesn't really need heating (it's heated by the warmth radiating up from the lower floor). It used to be extremely drafty and that balsam wool had almost no insulating value.

The insulating foam is applied directly to the underside of the roof decking, between the rafters. This eliminates the "vented" roof assembly and keeps the hot and moist/cold and dry air from entering your attic area in the first place. No fans required, no vents, and it feels far more comfortable.

One of the projects coming up will be relamping the whole house for LED lighting or "tube" fluorescent lamps. CFLs really aren't a terribly efficient choice--fluorescent "tube" lights beat them hands-down. Plus, every CFL has to have a ballast (that big base) in order to be compatible with the incandescent base. That ballast is a throwaway when the lamp goes out, unlike the dedicated fluorescent fixtures that have a built-in ballast and you just replace the tubes. Though I have several CFLs installed, I'm not buying any more and will relamp in lieu of continuing to buy a product that is inherently wasteful.
