Do you want the good news or the bad news first?
I tend to vote for the bad news first.
Last spring when the Production reports were being generated there was a significant flaw with the weather normalization that affected nearly a third of the homes being modeled. No, it wasn't a bug in BEACon, no there wasn't a formatting error with the consumption data from the utility companies.
I forgot to use current weather data from NOAA...
Fortunately, for the majority of the homes, there was only one month where there was no weather data to help normalize the consumption data. However, since NIPSCO provided consumption data for their customers in early 2014, there were many, many more clients affected by the lack of weather data.
Acting on feedback and independent investigation from a small handful of persistent Weatherizers, a review of the old consumption data with more current weather data was done. And now comes the good news.
The average net natural gas savings during that evaluation period wasn't a tepid 15.4%, but a healthier 18.4%. The average net natural gas savings went from 163 therms up to 200 therms.
In all, 10 weatherization providers were affected. Nearly all had significant increases in their average net natural gas savings:
- Area Five
- original: 5.9%
- revised: 28.3%
- Area IV
- original: 16.9%
- revised: 23.1%
- CANI
- original: 10.9%
- revised: 27%
- Human Services
- original: 17.3%
- revised: 18.6%
- North Central CAA
- original: 15.9%
- revised: 25.5%
- Northwest CAA
- original: 14.9%
- revised: 23.3%
- Real Services
- original: 7.9%
- revised: 15.8%
- Housing Opportunities of Warsaw
- original: 7.2%
- revised: 17.4%
- Indiana Builders Association
- original: 10.3%
- revised: 13.2%
- Miami County YMCA
- original: 17.3%
- revised: 23.7%
