HoA-REC&N is located in a new eco-friendly building in the Gullele Botanic Garden (GBG), Addis Ababa, Ethiopia. The building houses all of the staff of the Centre and was built using the “cradle to cradle” philosophy. GBG is a joint undertaking between Addis Ababa University and the City Administration of Addis Ababa. The Royal Government of the Netherlands has playe a key role in its establishment  by providing technical and financial support.

HoA-REC&N received on 16 March 2017 the prestigious Leadership in Energy and Environmental Design (LEED)®Gold Green Building Certification from the US Green Building Council. HoA-REC&N’s HQs building became the first Ethiopia green building to have received LEED Certification award.

Water Efficiency

  • All toilets provide 50% reduction in water use
  • All plumbing fixtures provide 45% reduction is total water use
  • The landscaping installed does not require permanent irrigation systems.

    • Cooling and heating is not needed based on location and therefore saving about 1500 kWh of energy usage.
    • Photovoltaics will be used to provide 25,719 kWh annually.

Materials & Resources

  • Recycling is encouraged throughout the project
  • Over 95% of construction waste was recycled
  • Over 20% of construction has come from local sources such as adobe brick and eucalyptus
