New Caanan Net Zero

This is a four bedroom, four and one-half bath home with a two bedroom apartment above the garage with a separate entrance.  Located within easy walking distance of the downtown area, this new home offers plenty of space and luxurious finishes for a comfortable lifestyle.

Although a net zero claim takes time to verify, the Home Energy Rating Score (HERS) of -10 indicates that this home might just achieve this significant mark of remarkable energy efficiency.
