Representative Technologies
Aluminum Curtain Wall Strengthening Insulation Performance
Technology
overview
- Satisfying heat transmission coefficient of 1.3W/m2K or less by applying low-e glass to the aluminum curtain wall combining factor technology, which improves insulation performance
Effects
- 20% cost savings are realized compared to the general triple-glass curtain wall system having the same thermal performance.
Applied Projects
- The curtain wall is scheduled to be applied to the supplementary facilities in new project sites in 2021.
Intellectual
Property Rights
- Patent Application No. 10-2019-0068692: insulation curtain wall system
Optimum Design Technology of Water Piping using BIM
Technology
overview
- Technology that can optimally design the pipe diameter, pumping head, and distribution performance of the water piping system using BIM-based 3D piping model
Effects
- Quality improvement including water piping system’s pipe cost savings, pump capacity optimization, and pipe’s distribution performance by combining BIM technology with water piping design
Applied projects
- Applied to district heating sites including e-Pyunhan Sesang Sejong River Park
Intellectual
Property Rights
- Patent Registration No. 10-2033620: water piping design method using BIM system
- Program Copyright Registration No. C-2018-001789: Eco-flow designer
Air cleaning ventilation system
Technology
overview
- Total heat exchange ventilation system by which indoor air can be cleaned using the internal circulation mode and high-performance HEPA filter on days with high fine dust concentration
Effects
- A pleasant indoor environment is provided without worries about fine dust by applying high-performance HEPA filter (including air cleaning function by which 2.5㎛ or finer dust can be removed by 99.9% and 0.3㎛ or finer dust can be removed by 99.5%).
Applied projects
- Applied to e-Pyunhan Sesang Chuncheon Hansup City, Terrace Opo
Intellectual
Property Rights
- Patent Registration No. 10-1638065: ventilation system with air filter and bypass route and ventilation method using such system
Optimized Floor Cushion Pad to Prevent Noise between Floors
Technology
overview
- As a complex structure of EPS and EVA, lower limb structure-type EVA is applied to the bottom of the buffer material, and slab-type EPS is applied to the top. Thus, it is a high-performance floor cushion pad forming the floating structure
Effects
- World’s top-level heavy impact sound reduction performance (acknowledged performance: light impact – grade 1, heavy impact – grade 2)
Applied projects
- Applied to the floor structure of all apartment units of e-Pyunhan Sesang / ACRO
Intellectual
Property Rights
- Patent Registration No. 10-2015-0031027: composition of ethylene vinyl acetate for cushion pad to reduce the floor noise of apartments
Integrated Sensor to Manage Indoor Air Quality
Technology
overview
- Integrated sensor that automatically manages indoor air quality through the measurement of five factors of indoor air quality (fine dust, CO2, VOCs, temperature, and humidity) and linkage with the air cleaning ventilation system
Effects
- As an item of the smart air control system, indoor air quality is automatically controlled without the occupant knowing. Indoor ultra-fine dust state is indicated through intuitive display.
Applied projects
- Applied to ACRO Seoul Forest, Deoksugung The Place, Gamil ECON e-Pyunhan Sesang
Intellectual
Property Rights
- Patent No. 10-2019-0096825: indoor environment sensor installation device with the separated structure of air intake and discharge domains
