Nowon EZ House, Korea's first zero-energy multi-unit housing complex, is the result of the project “Zero Energy Housing Activation Optimization Model Development and Demonstration Complex Development”, which was initiated by the Ministry of Land, Infrastructure and Transport, Seoul Metropolitan Government, and the northeast residential district of Seoul “Nowon-gu”.
It was completed in September 2017, and in August 2018, the building 102 received the passive house certification for the first time in the Korean housing sector from the German Passive House Research Institute.
Nowon EZ House was built using the highest level of passive technology and materials in Korea, some of which were the first to be used in the country. Structural thermal break solutions Schöck Isokorb® XT type K and XT type Z have been applied to prevent the thermal bridges in the balcony area. Thanks to the new technologies, EZ House is aimed to maintain a temperature of 20°C to 22°C in winter and 26°C to 28°C in summer – without any heating or cooling. In addition, renewable energy technologies such as 1,800 solar panels and geothermal heat pumps help to generate environmentally friendly energy used for cooling, ventilation, lighting and for even more warmth.
A total of 121 households in Nowon EZ House build up big data by collecting thousands of data by minute through separate measurement. It is expected to become an asset that can improve Korea's ZEB (Zero Energy Building) level in the future.
