Having been awarded the LEED Gold certification, the President Place building is considered the greenest building in the city. The building has been designed to create an exceptional balance between work, life and the environment. The 9th and 13th levels of the building have green roofs and terraces. President Place selected climate-tolerant plants that can survive on natural rainfall, and thus the green roof system does not require a permanent irrigation system. Effective practices were considered during the installation of the green roof, such as mulch for trees to conserve moisture, choosing plant species that can easily adapt to the site and need less irrigation. Trees have also been planted on the ground level. Additionally, the building is surrounded by permeable paving to help rainwater percolate easily. The aim was to create a visually appealing office building that leads the way in environmental, design-led construction in Saigon. [1, 2]

Overview

Nature-based solution

  • Nature on buildings (external)
  • Green roofs
  • Grey infrastructure featuring greens
  • Alley or street trees and other street vegetation

Key challenges

  • Climate action for adaptation, resilience and mitigation (SDG 13)
  • Climate change adaptation
  • Water management (SDG 6)
  • Stormwater and rainfall management and storage
  • Green space, habitats and biodiversity (SDG 15)
  • Green space creation and/or management

Focus

Creation of new green areas

Project objectives

1. To reduce the heat island effect. 2. To retain stormwater and, minimize stormwater runoff volume within the building. 3. To provide insulating benefits to maximize energy savings. [2] Since one of the main objectives of the project is focused on adaptation to high temperatures and the creation of an effective water management system, when selecting vegetation for the green roof, emphasis was placed on climate-tolerant plants that can stand harsh conditions [1, 2].

Implementation activities

Vegetated roofs are installed to beneficially reduce the heat island effect by replacing heat-absorbing surfaces with herbaceous plants, shrubs, and small trees to cool the air through evapotranspiration. The roofs are also designed to retain stormwater to prevent flooding, with soil more than 1.5 meters deep, which required significant structural support underneath. With this thick soil layer, the “pots” function as stormwater basins for detention and retention. In addition to the green rooftops, the ground is built with permeable bricks which increase infiltration during the rainy season. [1,2]

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
  • Increase the use of climate-resilient plant species (resistant to drought, fire, and pests)
