Report analyzing design heating loads in superinsulated buildings
Author(s): Poerschke, Beach, Beggs
Organization(s): IBACOS
Publication Date: June, 2017

IBACOS investigated the performance of a small-diameter high-velocity heat pump system compared to a conventional system in a new construction triplex townhouse. A ductless heat pump system also was installed for comparison, but the homebuyer backed out because of aesthetic concerns about that system. In total, two buildings, having identical...
