This unique residential loft earned the Overall Competition prize in the 2020 SIP Building Excellence Awards. The use of structural insulated panels (SIPs) on top of an existing 3-story structure reduced crane time and labor while providing a warmer interior for mechanical rough-in during the cold winter. Building with SIPs allowed large efficient windows for great views including the downtown Minneapolis skyline. The airtight SIP building envelope helped the home achieve a low 32 HERS index with blower door test results of 0.80 ACH50  The SIP walls, floor and roof were manufactured by Energy Panel Structures.
