[Asia Economy Reporter Kim Hyemin] Ssangyong Construction, together with Lotte Construction, has developed a 'Zero Energy Construction Method' that drastically reduces heat loss in buildings and received government certification.

Ssangyong Construction announced on the 16th that it obtained the Ministry of Land, Infrastructure and Transport's Green Technology certification for this method on the 20th of last month. The method is named 'Thermal Bridge Reduced Exterior Insulation Construction Technology Using Truss Insulation Frame (TIFUS)'.

This method is characterized by minimizing the escape of heating and cooling energy generated inside the building to the outside, thereby reducing energy consumption compared to existing methods. Instead of the hollow steel angle pipes previously used for installing exterior wall finishing materials, the method replaces them with frames filled with high-performance insulation materials that ensure structural stability.

These frames improve insulation performance by about 20% compared to steel angle pipes and reduce installation costs by approximately 13%. For fire safety, glass wool, a quasi-non-combustible insulation material, is filled inside the exterior walls, and both the interior and exterior are constructed with vapor-permeable waterproof sheets and moisture barriers to prevent leakage and condensation.

Ssangyong Construction has been jointly developing this technology since 2018 with Lotte Construction, TIFUS Korea, and Saint-Gobain Isover Korea, and in September last year, the method was recognized and designated as a new construction technology.

The recently obtained Green Technology certification is a government system that certifies technologies minimizing greenhouse gas and pollutant emissions through energy saving and efficiency. Certification grants additional points in the Public Procurement Service's pre-qualification (PQ) for three years.

A Ssangyong Construction official stated, "We will continue to invest in developing new technologies and construction methods in preparation for the mandatory implementation of zero-energy buildings."

Meanwhile, Ssangyong Construction holds 110 patents related to construction.
