IGIS Asset Management is committed to sustainable growth, ensuring that urban real estate assets are managed in an environmentally responsible manner. Guided by the belief that "spaces created by people can coexist harmoniously with nature," IGIS integrates sustainability principles across its operations.

Located in the heart of Gwanghwamun, Seoul, Twintree Tower is a prime office building that embodies ESG values through its distinctive design, which harmonizes tradition and modernity. Designed by renowned Korean architect Byoungsoo Cho, the building is envisioned as a sustainable space that seamlessly connects the city, nature, and people, incorporating innovative approaches to environmental responsibility and public accessibility.

Environmentally Responsive Design

Twintree Tower was designed to blend with its surroundings while respecting the architectural character of the area. Its three-dimensional curved façade and horizontal bands complement the transparency of the glass curtain wall, creating a dynamic interplay of texture and depth.

The post-tensioning construction method was applied to achieve thinner slabs and higher ceilings, optimizing spatial efficiency and structural stability. Additionally, the tower features a pedestrian passageway that seamlessly connects to Dongshipjagak Pavilion at Gyeongbokgung Palace, enhancing public accessibility and integrating the building with its historical and urban surroundings. This design reinforces Twintree Tower’s role as a model for sustainable architecture that harmonizes with both the city and nature.

Sustainability Goals and Real-Time Environmental Management

Twintree Tower has set mid- to long-term sustainability targets, aiming to reduce energy consumption and greenhouse gas emissions by 5% and water consumption by 10% by 2033. To achieve these objectives, the building employs systematic environmental data management and actively incorporates eco-friendly technologies, including energy-efficient systems and solar power generation.

Environmental Performance in 2023

As of 2022, Twintree Tower has established a strong foundation for sustainable operations, reporting greenhouse gas emissions of 3,089 tCO₂eq and energy consumption of 6,909,371 kWh. Building on this progress, the building continues to improve energy efficiency and enhance environmental performance through ongoing investments in sustainable infrastructure.

Global Certifications and Industry Recognition

Twintree Tower has achieved LEED v4 Platinum certification, the highest rating awarded by the U.S. Green Building Council (USGBC), demonstrating its excellence in energy efficiency and sustainability. Additionally, the building has earned an Energy Star score of 91, reflecting its high operational efficiency.

Since 2022, IGIS Asset Management has actively participated in the Global Real Estate Sustainability Benchmark (GRESB) assessment, earning five Green Stars and securing a position in the top 20% of global performers in sustainability.
