Energy and Environmental Policy

NHN establishes and implements the following Energy and Environmental Policy to minimize negative environmental impacts that may occur by providing various IT-based services, and actively respond to global climate change by improving energy efficiency and minimizing GHG(greenhouse gas) emissions.

1. All NHN executives and employees must participate and practice actively in Energy and Environmental management activities to implement the policy.
2. NHN follows relevant laws and guidelines regarding energy & environmental regulations.
3. Reduce GHG emissions by applying energy-efficiency technology and increasing the use of renewable energy. 
4. Commit to reduce waste and conserve resources, and consistently promote to solve the environmental problems.
5. Purchase Eco-friendly and high energy-efficiency product by priority.
6. Conduct regular energy and environmental inspection and disclose the results to stakeholders.
7. Encourage activities for preserving biodiversity and protecting ecosystems.

Urban Eco-friendly Data Center

  • Power Usage Effectiveness

    The average annual PUE* of NCC1 stands at 1.25 boasting high energy efficiency which is quite close to 1 compared to the average PUE of 1.8 for data centers in Korea.

    • PUE(Power Usage Effectiveness) : As a value obtained from dividing the total amount of electricity used in the data center by the electricity amount consumed by IT equipment, the closer to 1, the more energy efficient the data center is.
  • High-density Operating Environment

    The server room is composed as an independent module and the rack width is adjustable from 19 to 23 inches considering the IT life cycle where the server generation changes. It offers high-density capacity that allows an average of 4 times more power than a typical domestic data center as well as an environment optimized for cloud computing through UPS power supply.

  • Energy Efficiency Improvement

    The ‘indirect vaporization cooling’, which was patented for the first time in Korea, and a shielded environment* void of raised floors minimize power loss. The energy saved through such effort is equivalent to planting 1,300 pine trees per year.

    • The front of the server faces the frontal part of other server and the back faces back.
      Cold air flows into the front of the server and heat rises from the back of the server.
      Different pressures are applied for the cold air inlet passage and hot air outlet passage to prevent air from mixing with each other.
  • Unmanned Data Center

    It has remote management environment that minimizes customer visits and resident manpower. Anyone could tap into the cloud that incorporates customer’s equipment with NHN equipment.
    Based on the NHN's server management and operation know-how, we can even provide consulting for clients who lack professional manpower.

  • Energy Reduction Strategy
    • Select products for water / power consumption reduction

      Applied water-saving toilets and faucets, LED lights, standby power blocking system, various sensors, vertical louvers, lighting control, lower air conditioning, low-e double glazing

    • Utilize natural light and ventilation

      Natural light using sunken garden, ceiling and vertical louvers, natural ventilation through hive and roof ventilation windows

    • Improve space efficiency

      Create a multi-purpose space that combines the functions of a restaurant, cafe and event hall on the first basement floor in order to increase space efficiency and reduce power consumption when moving

    • Reduce elevator power consumption

      By making an internal staircase separate from the emergency staircase, we facilitated movement between floors without having to use the elevator

  • Material Using Strategy
    • Reduce material consumption

      Column-free space and space plan that can be easily disassembled and organized + partitions that are easy to move

    • Reduce wasted material

      Creating the table made to the size of the material and planning the modular space

    • Using raw materials as they are

      Selecting unprocessed materials those emit less volatile organic compounds and those without formaldehyde or resin

    • Utilizing materials considering nature's recovery speed

      Applying access floor made with bamboo which had received certification for being eco-friendly

    • Using recycled/waste materials (products)

      Using products made from recycled plastic and bamboo access floor board made with waste paper Using product packaging boxes as a finishing material for parking lot elevator halls

  • Strategies to reduce pollution
    • Minimize carbon emissions

      Provide bike parking spaces and showers, and offer parking spaces for highly-efficient cars and carpool vehicles

    • Landscape Planting

      Planting many plants inside the building for fresh air

    • Environmental pollution management plan

      Implement environmental pollution management plan to reduce pollution from the construction site

    • Reducing indoor air pollutants

      Building a structure void of adhesives, and using eco-friendly adhesives

  • Strategies for continuous eco-friendly building operation
    • Encouraging active participation among users

      Providing easy-to-understand eco-friendly guides and conducting energy saving campaigns
