When there are hundreds of data points collected for each home and infinite variations of home energy components (and behavioral factors), can we realistically expect the data collection and energy predictions to be accurate?

In addition, quantification is great. But how do home energy ratings make a compelling reason to make home energy improvements when the energy savings is modest and the inherent value proposition of comfort, health and a modern lifestyle are not included in the home summary?

Keep in mind that I am asking about Ratings with software modeling, not Audits that are more subjective but still may use diagnostic tools like a blower door.

lol. Turn off subsidies for oil and gas and I'll be able to sell solar panels without tax credits.  Take away subsidy for corn and America's diet gets a whole lot healthier.  But then what will our Health Care sector do?  Poor big Pharma!!

 

Every move we make relates to a subsidy.  

 

True performance based incentives are paid later, after the performance is proven.  

 

Show me the proof.  Make it easy for me to see. 

You may get your wish very soon as the collective political will is turning against government spending.  That is why the retrofit industry must find proven metrics in order to survive a "free market".  The new construction market has that already. 

Phil, didn't see you here. Great post. Banged that one. The importance of asking stat habits emphasized very nicely. Marginal propensity to freeze your butt off. T-stat elasticity curve! (funny stuff!)

Success with customer, to me, is measured by your promised/delivered ratio compared to your competitions.


If you game your savings to make SIR, you know savings won't follow. Where is accountability for this? It can't be job to job, it needs to be more statically accurate than that. By taking the average, or even charting it and deleting outliers, a picture of performance will appear.

This is really a crappy BB engine.  

 

Replies are all over the board instead of top to bottom, and since they are not specifically time stamped chronology is nearly impossible to follow.
