Geoje Bluefarm – Geoje-SI
Gyeongnam, South Korea


This international agricultural/residential project shows new promise for SIPs acceptance around the world.

Certified by the Passive House Institute Korea (PHIK), this mixed-use building is located on blueberry farm with the ground floor used for packing blueberries and temporary storage. Second floor is a residential area. Located in a mountainous region with very cold Winter temperatures, the owner requested nonconventional construction methods for energy savings and comfort year-round.

SIP construction costs more initially but saves energy, more than 60 percent, and saved 50 percent on labor costs. As an added benefit, the tightness of the SIP building envelope prevents outside polluted air from entering the interior space. This project utilizes cutting-edge, graphite-enhanced EPS polymer technology provided by SIPA member, BASF.

Total conditioned space: 1,501 sq. ft.
Walls are constructed with 6.5" Neopor SIPs
Roof is constructed with 8.25" Neopor SIPs

PHIK index: 24 (a South Korean equivalent to HERS rating)
Blower door test: 0.68 ACH @ -50 PA
