hanmiglobal

HanmiGlobal recognizes the significance of the building sector, which accounts for 32.8% of Korea’s 2050 carbon-neutral target, and is committed to helping achieve that goal through technology development and advanced engineering solutions. Effective carbon reduction in Korean construction requires a clear understanding of where and how emissions occur across the entire project life-cycle, from financing, planning, and design to material production and transport, construction, and operations. Studies show that embodied carbon in building materials and operational carbon during the use phase together represent more than 80 percent of a project’s life-cycle emissions. Responding to this challenge, HanmiGlobal is taking the lead in low-carbon design using timber, in top-tier building-energy management systems, and in engineering for offshore-wind facilities.

From early planning and design through construction and operations, the Company will deliver technology-based solutions that combine specialist engineering, green technologies tailored to each project, and disciplined project management, thereby benefitting clients and local communities alike. Dedicated operating teams, staffed by experts in each discipline, will apply differentiated technical capabilities to enhance sustainability throughout the full life-cycle of every project. Over the past two decades, HanmiGlobal has continually upgraded the functionality of its consulting, system, and solution offerings, with the ultimate aim of becoming a total green-solution provider that lets clients access all environment, energy, and climate-change services through a single integrated platform.

Carbon-Reduction Engineering

Whole-Building Carbon Management via Life-Cycle Assessment (LCA)

Current Korean building policies focus mainly on cutting operational energy use. Green Building Certification, for example, addresses resource-efficient materials, eco-label products, and low-carbon materials. Still, it does not yet account for the carbon released during material production or at the end-of-life stage. HG PRECON team, therefore, adds carbon-reduction design control and whole-building LCA to the usual management set of design review, cost control, scheduling, and quality assurance. The team is building a standardized system that sets criteria for low-emission materials in the production phase and measures environmental impacts at demolition. This approach moves beyond energy-saving regulations to deliver truly green construction by evaluating materials and use and end-of-life impacts across the entire building life cycle.

Key Management Items and Analysis Systems for Carbon-Reduction Engineering

Managing a building’s environmental impact must move beyond energy-use reduction to include sustainable material choices that cut emissions at the production stage. For that reason, life-cycle assessment of the entire building is essential.

Gaeunsan Village (Jongam-dong) Street Housing Renovation Project  

Gaeunsan Village Street Housing Renovation Project located in Seoul’s Jongam-dong, designed by Gansam Architects & Partners, constructed by Bomi Construction, and managed by HanmiGlobal as the project manager, is a representative low-carbon and eco-friendly residential project. With a total project area of 23,404 ㎡, the development consists of 130 residential units in a building ranging from three basement levels to 20 above-ground floors. The project features the housing association’s own apartment brand, “Commons.” The building incorporates a passive house design through external insulation, focusing on significantly improving insulation and airtightness performance while reducing carbon dioxide emissions. In particular, the project is the first in Korea to apply wooden structures and OSC (Off-site Construction) methods to selected units (18 households). Based on this innovative approach, the project aims to become the first apartment development in Korea to obtain both Passive Building Certification and Carbon Neutral Building Certification in the future.

Using Renewable Resources such as Solar Power and Geothermal Energy

To achieve carbon-neutral goals, it is essential to reduce building energy consumption and draw on renewable sources. Efficient use of natural energy, such as solar photovoltaic (PV) arrays and geothermal heat-pump (GHP) systems, cuts operational carbon while improving overall energy performance. In the long run, these technologies lower utility costs and deliver environmental benefits, raising a building’s sustainability profile and accelerating the transition to a net-zero society.

Gak Sejong Data Center Project

Gak Sejong, NAVER’s newest hyperscale data center, combines state-of-the-art technology with nature-friendly design to promote a sustainable future. By harnessing rooftop solar PV and geothermal heat-pump technology, the campus prioritizes lowering electricity demand and the related CO₂ emissions. The facility occupies 293,963 m²—roughly 41 soccer fields—and is six times larger than the company’s first data center (Gak Chuncheon). Solar PV panels installed on the server-hall roof generate 184 MWh of electricity per year, while geothermal heat pumps deliver efficient heating and cooling, saving 13,363 MWh annually. Thanks to sustainable land use, energy and air-quality measures, indoor-environmental quality, and six other evaluation categories, HanmiGlobal secured LEED Platinum certification for Gak Sejong.

Smart Green Solution

GHG and Energy Management

In the building sector, systems that monitor and control energy use and associated greenhouse-gas emissions during operations are essential to achieving carbon neutrality. Ecosian, a HanmiGlobal subsidiary, pursues the vision of becoming “the world’s top expert group leading knowledge industries in the environment and energy fields” and is already Korea’s No. 1 firm for environmental consulting and energy solutions, with unmatched credentials and staff expertise. By combining HanmiGlobal’s construction-management capabilities with Ecosian’s know-how in energy efficiency and environmental consulting, the two companies generate synergies in green buildings, construction IT, and renewable-energy projects. Pre-occupancy energy assessments and optimization of indoor environmental and energy performance reduce waste, while advanced ICT-linked systems cut electricity and fuel consumption, delivering low-carbon, green buildings. Ecosian filed and registered four technology patents in 2022 and one in 2023, undertook seventeen government-funded R&D projects during the same period, and in March 2023 earned “Good Software” quality certification from the Telecommunications Technology Association of Korea for its ES-BEMS building-energy-management platform. In 2024, the company began researching an AI-based autonomous space-control technology that maximizes energy efficiency while maintaining occupant comfort in each zone of a building. Working in close partnership, HanmiGlobal and Ecosian integrate this advanced energy-management technology with their growing big-data resources to deliver comprehensive consulting on environmental issues.
