Recently local natural gas supplier National Grid initiated a program to track users' energy consumption in relation to their neighbors.
Each month, consumers get a rolling 12 month summary of their usage compared to the average, and the 80th perctile, of his neighbors. Neighbors are defined as "approximately 100 occupied nearby homes that are similar in size to yours and have gas heat." On my report that average was 5,340 sq. ft.
The results for winter 2010-11 are in, and it appears that the Energy Tab house is among the most efficient -- and quite possibly the most efficient -- in the 'hood. For the period December through February, consumption of fuel is below. (I've pro-rated our usage to adjust for our size differential vs. the average home.)
