DL Construction Earns 'Green Technology Certification' for Elevator Method Reducing Carbon by 80%

Concrete Usage Reduced by 84% with Steel Plates
Eco-Friendly Construction Technology Leading ESG Practices

DL Construction has officially been recognized for its eco-friendly construction capabilities by obtaining 'Green Technology Certification' for its outstanding carbon emission reduction technology.

On May 27, DL Construction announced that the 'highly corrosion-resistant elevator pit construction technology,' jointly developed with Lotte Construction, Doosan Construction, and JTech ENC, received Green Technology Certification (GT-25-02267) from the Ministry of SMEs and Startups in April.

The Green Technology Certification is a government system that certifies promising eco-friendly technologies based on the 'Framework Act on Carbon Neutrality.' It is awarded to technologies that minimize environmental impact, such as carbon reduction, clean energy, and resource circulation. Eight ministries, including the Ministry of Trade, Industry and Energy and the Ministry of SMEs and Startups, are responsible for the evaluation process.

The certified technology replaces the traditional concrete casting method by constructing elevator pits using highly corrosion-resistant steel plates, side waterstop keys, and multipurpose steel bars to form a steel structure. This approach reduces excavation depth and the amount of base concrete required, significantly decreasing raw material consumption.

In practice, the amount of steel used is reduced by approximately 72% compared to conventional methods, and concrete usage is reduced by about 84%. Applying the carbon emission coefficients set by the Korea Environmental Industry and Technology Institute, greenhouse gas emissions for a 600-unit apartment complex, which previously amounted to 295,000 kg, are analyzed to drop to about 57,000 kg?a reduction of nearly 80%.

A DL Construction representative stated, "This technology satisfies both the economic and environmental requirements of buildings, while also aligning with the national carbon neutrality strategy. We will continue to strengthen ESG management by developing and expanding the application of green technologies."
