Twenty Mile South Farm zeroes in on perfect efficiency

Idaho’s first commercial Net Zero Building, the Twenty Mile South Farm (TMSF) is a 14,000 sq. ft. biosolid processing facility with administrative offices and a maintenance building. By pushing beyond code through increased envelope insulation, use of ground-source heat pumps, reduced infiltration, and use of a heat exchanger for ventilation, the design team created a facility that has consistently achieved significant energy savings on an annual basis.
