Lisbon, Lisboa (FUA), Portugal
City population: 2679729
Duration: 2009 – 2012
Implementation status: Completed
Scale: Sub-microscale: Street scale (including buildings)
Project area: unknown
Type of area: Residential, Central Business District / City Centre, Building
Last updated: October 2021

The vertical gardens were installed on a property whose two street-facing facades are almost entirely covered with layered greenery. The building is a mini-lung and an example of sustainability for the city, keeping the principles of a living habitat and a relationship with the outside, assuming a revitalizing urban role. Its walls are completely covered with vegetation, creating a vertical garden, with around 4500 plants. (ref.3, 1)The architect who designed the property was originally commissioned to transform an old building but serious structural problems meant the building had to be demolished, and with the chance to start from scratch, considerations for a more radical design began.

Creation of new green areas

Project objectives

1) Provide an example of sustainability housing for the city of Lisbon, keeping the principles of a living environment and a relationship with the outside, assuming a revitalizing urban role. (ref.3) 2) Create a vertical garden with low levels of water consumption as well as little gardening challenges. (ref.3) 3) Include plants that would thrive in the Lisbon climate, which meant plants native to Portugal (ref.1) 4) Choose plants that stay green throughout the year and insulate the property, making it cooler than a conventional house in summer (ref.1) From a climatic point of view, a number of positive aspects can be pointed out: this green façade absorbs CO2 (thus helping to reduce CO2 levels), improves air quality, and works as a natural layer of insulation for both temperature and noise. (4)

Implementation activities

Search for plants that would thrive in the Lisbon climate, which meant plants native to Portugal. Like other vertical gardens, this one is built by layering the plants over an acrylic layer that channels a nutrient-rich solution of water to their roots. (ref.1) The vertical garden helps the building thermally. There are solar panels above the elevators for water heating, and the very concept of architecture also makes it sustainable, as it brings nature into the centre of the city. The vertical green facades act as a mini lung and an example of sustainability for the city of Lisbon, increasing the green space in an innovative way by implementing it in a building. (3)

Climate-focused activities

Climate change adaptation:

  • Increase or improve urban vegetation cover to help reduce outdoor temperature
  • Implement green walls or roofs to lower indoor temperature and provide insulation

Climate change mitigation:

  • Improve carbon sequestration through selection of more adaptable species
  • Install vertical or horizontal artificial surfaces that help with carbon storage and cooling
