Igor Zhadanovsky commented on Igor Zhadanovsky's blog post Bang for the buck: deep-energy retrofit approach"Ted,
Thanks for continuing discussion.
If you check the blog, there is no statement about payback period bar limits for investment. The point is choosing the most efficient investment. Looks like sometimes you have difficulties in justification of…"
"Thank you Ted. Great response!"
tedkidd commented on Igor Zhadanovsky's blog post Bang for the buck: deep-energy retrofit approach"One more try to explain how "simple payback" doesn't recognize VALUE.
If you are a building owner reviewing a $10,000 improvement that saves $500 a year, let's say the improvement increases the value of your building by…"

Tom,
Actually, I never thought about connection between short payback period and frequency of Americans moving. Good point – thanks.
There are energy improvements with payback period longer then seven years though. Such…"

Richard,
Again, your questions are in bold italic and my answers follows. Also, none of the specific questions I asked so far was answered, - I’ve repeated them at the end of this post. Hope to see…"

Plz give your best answer to the arguments you've been making on a national scale. What would/are you doing and what do you see as the final solution for the built environment in lowering energy use.

Igor Zhadanovsky commented on Igor Zhadanovsky's blog post Bang for the buck: deep-energy retrofit approach"Ted,
Richard made the point about difference between Green and EE, which roughly is difference between intangible and tangible benefits.
Both are important but priorities depend on particular situation. Not many landlords/house owners has the…"
Igor Zhadanovsky commented on Igor Zhadanovsky's blog post Bang for the buck: deep-energy retrofit approach"Richard,
thanks for clarification, difference between Green and EE.
Unfortunately, all the available information about Empire State Building is not consistent.
At least amount you mentioned - 106 (93 + 13) millions is close enough to 120…"
tedkidd commented on Igor Zhadanovsky's blog post Bang for the buck: deep-energy retrofit approach"Richard, you have a nice way of explaining things. Maybe you can explain how attempting to parse the savings of one piece of a comprehensive design turns into a spherical cow analysis. Like looking at a three legged stool and asking if you can get…"
"Igor
Your right there is no cost to savings comparison on each up-grade.
The best I can tell you is that the capital budget for energy related projects was $93 million with no energy savings with additional $13 million (invested into…"
Igor Zhadanovsky commented on Igor Zhadanovsky's blog post Bang for the buck: deep-energy retrofit approach"Richard,I followed the link http://blog.rmi.org/blog_empire_state_retrofit_surpasses_energy_savings_expectations
There is a nice breakdown on savings produced (seven items), it will be great to know the cost as well to figure out what…"

Here's the full story after the retrofit:

Bang for the buck: deep-energy retrofit approach
"Americans can always be counted on to do the right thing...after they have exhausted all other possibilities." Winston Churchill
How much does it cost to perform a deep-energy retrofit at a 100-year-old single-family home? Thanks to a recent study in Utica, New York, we now know the answer: about $100,000.…
