The round design of the Deltec Home is exceptional at reducing energy-robbing drafts.
The same aerodynamic design that makes our homes perform well in high winds also allows fewer drafts.
Compared to the long, straight, exterior walls found in a typical home, there is simply not enough
surface area on any one side of the house to allow pressure to build up. Less pressure equates
to fewer drafts. According to the U.S. Department of Energy, 25-40% of a typical home's heating
and cooling energy use is due to air leakage.
