I chose no time or technology to measure. We need to replace all the windows in the house and some duct work. All that will eat up time and lots of money. Once those energy drains are fixed we could focus on reducing consumption. Does anyone know a really good 3D printer for houses? We could use a quick built home. 3D printing (building!?) seems like a good choice :)

It sounds as though the trick is in making a programmable thermostat much easier to use, because in theory, even 'basic' programmable thermostats can support multiple temp changes each day and week.

@Michael, it really came organically out of the thermostat reading our daily life and optomizing for it. As an at-home worker, we had a "run it livable" all week. but with the nest, I made a habit of "clocking out" when i went to a tradeshow, lunch, or meeting. Also, when i was about to go to sleep, I would lower it (cuase i could without moving). I didn't feel like my life was nagatively impacted at all.

@Maryam, it was programmable, but pretty basic. We just had a monday through friday profile and weekends.

I selected "Other" because we do pay attention to energy consumption, and it's reduced some of our energy use and saved some utility bill money ... but I don't know that I'd call it a "bundle".

The major effort has been reducing A/C (electric) and heating (gas) consumption. We've seen some decline in both bills, but I'd have to do a lotta analysis to figure how much. The main gauge is cost — bill size — but obviously there's been a reduction in Kwh and BTU consumption.

Sounds like a successful investment. How long before it pays for itself? Also, have you considered the security/surveillance aspects? My neighbor just tore down and rebuilt his home, and he now pulls up camera feeds from nearly every room in the house on his smart phone.

That's an amazing stat, Hailey! What kinds of measures did you have to take to get that 30% improvement? Did it have any impact on your comfort?

Thanks for the insight, PC. Now that you've made those changes, what kinds of savings have you seen, ballpark?

I agree that temperature fluctuations can be (and are) a killer for those of us on the east coast, Maryam, but I've read that even slight adjustments (keeping the house at 72-75 in the summer and 68-70 in the winter, for example) can yield significant savings. Can these what-if analyses be run on the data?

Depending on the granularity of the data, Terry, you could get an earlier alert when a fixture is leaking, when an appliance component may be failing, or you may be able to cut costs by running certain appliances in off-peak hours. You're also armed with detailed information when it comes to comparing your existing setup with potential alternatives. 

Are those of any value?
