Sosoljip net zero-energy house in Seoul bets on foam insulation to reduce energy consumption


Sosoljip House in South Korea_1

The high cost of energy, followed by the rising concerns about global warming and climate change have made architects and planners come up with different strategies to reduce energy consumption in new homes being constructed all over the world. Dr. Jung Soik was also pondering over the vulnerability of energy costs and then decided to build a net zero-energy home in Seoul, South Korea, which should serve as the model for environmentally conscious home building.

Dr. Jung then asked architects at Lifethings to design her dream home and the architects came up with an equally interesting way to reduce energy consumption of the house and let the house run entirely on renewable sources of energy. The idea then took shape as the Sosoljip home, which is based on common sense in its design, construction and budget.

Focusing primarily on insulation, the architects encased the entire reinforced-concrete structure in 20cm-thick Styrofoam, the insulation properties of which have been thoroughly tried and tested. To top the insulation, the architects made use of polyurea spray, which forms a tough and a waterproof surface. The size of the windows was also worked to so as not to undo the good work done by the foam insulation.

Gizmag notes that the Sosoljip House makes use of both photovoltaic and solar thermal panels to generate hot water and clean electricity. Moreover a sustainable wood-burning stove has also been used as a back-up. With an intensive insulation system in place, the environmentally friendly home doesn’t have any mechanized air conditioning system. The architects believe that the homeowners will only have to wear sweaters during the winter and will sweat a little in summers, which is just natural.
