Short description of the intervention
Banyuwangi International Airport in East Java is the first green airport in Indonesia and was recognized with an award from the Aga Khan Award for Architecture (AKAA) in 2021-22, the world's oldest and most prestigious architecture awards (1,2,3,4). This project was designed and implemented by Architect Andra Matin in 2018 as a corporate social responsibility project for the Banyuwangi Regional Government, Java, Indonesia (1,2,4). The project building was extensively inspired by the houses of the local Osing tribe (1,2). The project aimed to embody a highly efficient passive design, with its remarking green roof feature of a total area of 4765m2 that is planted with grass and routinely maintained (1,2,3,5,6). The green roofs act like a sponge for heat, light and water and conserve energy by maintaining a constant temperature inside the building, and as a result, the airport does not require air conditioning in the main area (5). The green roof of the airport improves air quality as it captures airborne pollutants and atmospheric deposition, and the plants on green roofs also filter noxious gases (5). The eco-friendly airport terminal construction utilizes 'Fast Flow Siphonic System', especially for conventional roof drainage (5). The regional government declared a 10 km radius 'No Development Zone' around the project, protecting the existing paddy fields and villages, which is an exceptional move given the general tendency to exploit land around airports commercially (1,2). The current airport site caters to around 300,000 passengers annually and allows for future expansion to accommodate up to 3 million passengers without encroaching on the No Development Zone (2).

Goals of the intervention
- To develop a green airport design which is aesthetically pleasing with biophilic connections and that caters to the hot climate through a large-scale, contemporary interpretation of vernacular passive design principles
- To focus on a green roof design, which serves as insulation and benefits environmental quality
- To create green spaces and use of passive (environmental) strategies for local temperature regulation
- To blend the project with its surrounding nature (existing paddy fields) and integrate nature into building spaces for users well being
- To use locally available sustainable materials with low maintenance costs
- To promote symbols of local culture typical of the community
- To develop the project as a corporate social responsibility project by raising funds and creating a great example of an environmentally friendly building (1,2,3,4,5).
Quantitative targets
-1,100 daily passengers to be served
-a 4,765 sqm area to be divided into two sections (2 massive pitched/hipped roofs) covered with grass
(1,2,3,6).
Monitoring indicators defined
- increase in green area
- local temperature
-number of passengers (1,2,3).
Climate change adaptation: What were the goals of the NBS?
Climate change adaptation: What activities are implemented to realize the conservation goals and targets?
Implementation activities
- Construction of a striking roof with an elevated green lawn that resonates with local architecture and invites the landscape of surrounding paddy fields into the airport. The eco-friendly airport terminal construction utilizes a 'Fast Flow Siphonic System', especially for conventional roof drainage (5)
- The pitched/hipped roofs are covered in grass rather than roof tiles, serving both as insulation and to blend the building into its setting. Each roof is additionally crowned with an array of timber-framed, asymmetrical pyramidal skylights that echo the traditional Banyuwangi headdress in form and incorporate perforated panels to draw warm air upwards and outwards – another Osing technique

As part of the project, other nature-based solutions were also integrated, specifically, two ponds, a green curtain area and an indoor courtyard:
-a koi carp (type of fish) pond and a plant-filled courtyard offer visual and climatic respite as passengers proceed through the airport (natural ventilation)
- another pond with a sunken mushollah (prayer room) is at the end of the pick-up/drop-off colonnade along the building’s southern edge (2,3).
- curtain creepers that act as a hanging element along the airport's periphery (from cast-in-place planter boxes tucked at first-floor slab) (3).

Please specify the roles of the specific government and non-government actor groups involved in the initiative
Banyuwangi Regional Government, Java, Indonesia and the Department of Public Works, Human Settlements and Housing of Banyuwangi Regency led the project (1,2,3). And the project was designed and implemented by Architect Andra Matin: An architectural Design Consultancy named 'andramatin', located in Jakarta, Indonesia

- This project was developed as a Corporate Social Responsibility (CSR) Project for which the Central Government financed funds. Hence, the Regional Government declared a 10 km radius 'No Development Zone' around the project area to protect the existing paddy fields and villages, resembling the project with utmost ecological importance (2).

Other Stakeholders for project implementation:
- Airport Operations: PT Angkasa Pura II as Airport Company, Jakarta, Indonesia
- Structure and Lighting: PT Candra Kencana, Banyuwangi, Indonesia
- Structure: Hadi & Associates, Jakarta, Indonesia
- Contractor: PT Nindya Karya, Jakarta, Indonesia

Low maintenance costs
Description of environmental benefits
From an energy efficiency perspective, the Banyuwangi Airport project prioritizes natural air flow instead of air conditioning, expecting to have benefits related to indoor temperature insulation and improved air quality. In addition, almost every corner is decorated with amazing green views. Apart from that, there is still a garden with a roof garden concept which is planted with a number of local grasses and plants, therefore highlighting local indigenous plants as well as increasing the green space area by protecting the agricultural land surrounding the airport as well establishing a 4,765 sqm green rooftop. (1, 5,8)
