Locality & Community: Daegu Bank Second Headquarters, Busan North Port Marina​

SPACE

: Regionality becomes operative when it is physically grounded in a sense of place and materially connected to its users—that is, the community. You cited the Daegu Bank Second Headquarters (hereinafter DGB 2nd Headquarters) and the Busan North Port Marina as examples demonstrating this. First, please tell us how

this theme was reflected in the DGB 2nd Headquarters.

Lee Myungjin (Lee)

: DGB 2nd Headquarters project began based on the trust built over 30 years since carrying out the design of the Daegu Bank Headquarters (1979). The area around Chilseong-dong, Buk-gu, Daegu was the mecca of the textile industry which drove South Korea’s economic growth in the 1960s and 1970s following liberation, and the site where the building is located was the former Daehan Textile factory grounds. Following the IMF financial crisis, the textile industry declined, leading to the city’s stagnation, and the site was left neglected for a long time. As development began in earnest amid the trend of urban regeneration in the 2000s, this project aimed to maximise public accessibility and civic value while fulfilling the original functions of a financial headquarters, grounded in the city’s history and placeness. Therefore, despite being a financial facility where efficiency and security are crucial, it only filled two-thirds of the legal floor area ratio (FAR) and dedicated 45% of its gross floor area to cultural spaces. By dividing the zones into the lower level (cultural facilities) and upper level (office facilities), and articulating the lower mass to a human scale to secure entry circulation open in all directions, we enabled citizens to closely access the lounge, gymnasium, book café, gallery, and concert hall. Consequently, it breathed vitality into the stagnant city, became a space of communication and coexistence with citizens, and had a significant impact on the revitalisation of the local economy.

: I heard that to achieve a higher green building rating, you implemented eco-friendly architecture through appropriate low-tech methods rather than introducing excessive mechanical devices.

Lee

: The DGB 2nd Headquarters is the project where Junglim Architecture first established the design process (SD, DD, CD) for sustainable architecture; internally, we call this the ‘Eco-friendly Integrated Design Process’. Guarding against greenwashing – adding eco-friendly elements after the design is completed – we conducted all stages of design, including analysis, alternative drafting, and decision-making, based on sustainability. While we could have met the requirements for a LEED Platinum rating by applying active systems, we chose to secure a LEED Gold rating by using passive methods, which deliver the greatest impact at the lowest cost. Every decision – from the method of site utilisation and density, the orientation and shape of the mass, the structural format and modules, the scale and depth of spaces, the design and details of the envelope, down to the optimisation sequence of mechanical systems and renewable energy – was based on environmental evidence. The designer was also deeply involved in construction and operation. After identifying the differences between the simulation and the actual site, measuring, analysing, and adjusting them, we predicted a 60% reduction in energy costs during the design phase. The energy savings data from one year of operation post-completion showed 55%, allowing us to achieve a result close to our initial goal.​
