Green Building Development and Management

Sustainable Real-Estate Development

Directions for Real-Estate Development

In order to minimize impact on the environment during overall lifecycle of real-estate development of green buildings, we consider land use and convenience, ecology and indoor environment, energy and environmental pollution, ease of maintenance, use of raw materials and resources, and water resource management. We promote real estate development projects with the objective of obtaining green building certification for all commercial and residential buildings. We strive to acquire third-party certifications such as G-SEED certification and Building Energy Efficiency certification.

Green Building Development & Management System

Green Building Development

To respond to the growing consumer demand for green buildings and achieve sustainable development and advancement, we take an eco-friendly design approach to developing work and residential spaces. We consider the design with an environmental point of view and use green-certified materials when constructing our buildings as well as implementing a range of technologies to manage water circulation, conserve energy and resources, reduce the discharge of pollutants, and mitigate energy consumption and GHG emission from buildings. Also, we have included various eco-friendly factors in spaces operated by SK D&D as environmental management becomes a key factor in products and services used by customers. We will continue to promote our projects to enable third-party assurance for SK D&D’s development businesses and residential spaces. In addition, we will continue to mitigate environmental impact in operation stage to provide services enabling green GHG reduction activities led by our customers.

Green Remodeling

We are realizing environmental values by revitalizing cities through remodeling projects. We provide pleasant and healthy living environments by improving energy efficiency through enhancing insulation and facilities as well as the interior and exterior of deteriorated buildings. We plan to put more efforts into the green remodeling project in line with major policies for implementation of national carbon neutrality.

Life Cycle Assessment of Episode

We have applied lifecycle evaluation to episode development and have proceeded with eco-friendly design considering all processes. Life Cycle Assessment (LCA) refers to the method of evaluating the environmental impact of inputs and outputs in the entire development process. We are deriving and managing the results of characterization values such as global warming (GWP) for the impact of buildings on the environment from raw material collection to disposal.
