DL Construction has obtained green technology certification from the Ministry of Small and Medium Enterprises and Startups, recognizing the excellence of its eco-friendly construction technology.
DL Construction noted that the 'corrosion-resistant elevator pit construction technology' developed in collaboration with Lotte Engineering & Construction, Doosan, and Jaytech E&C obtained green technology certification (GT-25-02267) in April.
Green technology certification is an accreditation for technologies that minimize the emission of greenhouse gases and pollutants by saving and efficiently using energy and resources throughout the entire process of social and economic activities, including greenhouse gas reduction technologies, clean production technologies, clean energy technologies, and resource recycling and eco-friendly technologies.
The technology certified this time involves constructing elevator pits with a steel structure using corrosion-resistant plates, side seals, and multi-purpose plates instead of the existing cast-in-place concrete method.
By utilizing this technology, the base of the EV pit is formed with a steel structure, reducing the excavation depth compared to existing methods and decreasing the amount of reinforced concrete used for the foundation. The amount of steel used can be reduced by about 72% compared to existing technology, and the amount of concrete used can be reduced by about 84%, significantly conserving raw material usage.
The application of this technology also has a significant effect on reducing carbon emissions. Applying the carbon emission coefficients based on the Environmental Industry Technology Institute's standards reveals a reduction in greenhouse gas emissions from 295,376.59 kgCO2 for a 600-unit apartment to approximately 56,854.83 kgCO2, a decrease of about 80%.
A DL Construction official said, "We will actively contribute to enhancing both the economic and eco-friendliness of buildings through the dissemination of corrosion-resistant elevator pit construction technology and to realizing the national carbon neutrality policy," adding, "We will strive for continuous green technology development and the expansion of field applications."
