The Green One UN House in Hanoi is the first of 16 pilot projects around the world that gather multiple UN agencies in a single building to encourage collaboration.
The project involved gutting and refurbishing of an existing apartment building besides constructing over an additional area of 2,500m2. A lobby on the ground floor welcomes visitors to a conference center with a 200-person capacity theatre and formal meeting spaces. A cafe space creates a dynamic hub for staff and clients to interact. It also includes a travel agency, a bank, and a learning and research facility.
An extensive stakeholder consultation and a rigorous design review process were performed to ensure that UN staff participate and have a share of ownership over the project.
After following LOTUS NR Pilot version and achieving Gold Certification (the highest rating in Pilot version) at Provisional Certification stage, the project decided to target Full Certification under LOTUS NR V2.0. In May 2017, the building successfully achieved Platinum Certification.
Sustainable features of the building include extensive use of green roofs, drought tolerant landscaping, low water use fittings, energy efficient lighting and air conditioning, reuse of the structure of an old building, use of low-VOC products and installation of photo-voltaic panels that supply around 12% of the building total energy demand.

"The sustainability of our societies around the world has always been and remains the central mission of the United Nations. This has been very clear from our founding over 70 years ago. It is stated in the UN charter and most recently in the Agenda 2030 which embodies the UN’s Sustainable Development Goals. By presenting the UN in Viet Nam with this award today, you recognize the unique role that the United Nations can and must also play in championing the leadership in Green Building design around the world."
