unsangdong architects have developed ‘energy+ green home’, employing environmentally friendly technology to realize a dwelling that offers an intelligent energy saving system. built according to the passive house certificat from passivhaus institut in german, the house is a direct result of the collaborative work between the korean firm of jang yoon gyoo, shin chang hoon, and kolon institute of technology (lee sung jin, team chief and yim sung gyun, CEO).

the aim of ‘energy+ green home’ is to present an energy zero housing prototype that follows three E+ concepts: energy+, sustainable energy  integrated with green technologies; eco+, environmental friendly housing; and emotion+, housing which stimulates the inhabitants emotions–the dwelling having been conceived using a total of 95 green technologies. most immediately the structure’s overall consumption is minimized by the application of high performance insulation and high density triple pane windows. the resulting air tight performance they give reduces air leakage to a minimium, in order that the indoor temperature is maintained at a constant.

energy+ is achieved through solar photovoltaic panels installed along sections of the rooftop thus allowing the house to run on non conventional heating and electricity methods (solely the power generated by sunlight during the day). additionally, new technologies, including a cooling radiator and natural lighting system with ventilation are integrated in order to maximize the residents’ overall comfort.

 the eco+ approach is evident in the green wall and roof structures which create a visual harmony between nature and architecture. the home also uses purified rainwater, while recycled plastic and lumber implemented into the construction of the furniture, adorns the interior spaces.

finally, emotion+ is achieved via several systems of kankan, a storage system conceived by kolon engineering & construction which are applied to optimize space. environmentally friendly wall papers and CO2 concentration monitoring are also used within the building, whereby 450 sensors are installed throughout the home to conrol the diverse number of scientific applications and green technologies at hand; while an E+MS (energy+management system) is set in place to save, combine and control the information on energy output and input through the connection of various elements within the house such as lighting, outlets, switches etc.

in wanting to combine the efforts of green technology with architecture in a subtle way, unsangdong architects have envisioned an expressive green roof which moves its way over the folds of the exterior, seamlessly integrating landscape and energy system all at once. the overall scheme of the rooftecture is one terraced landscape, with greenery moving over its faceted mountain-like silhouette.
