Abstract: Abstract Due to the rising numbers of developments in a land scarce and densely built environment like Singapore, the Singapore government has been encouraging the incorporation of sky-rise greenery in buildings. Despite the informed push to adopt Vertical Greenery Systems (VGS), the adoption of VGS is not as high as expected. In addition, very few studies have explored the views of building stakeholders towards the adoption of VGS in Singapore, and the influence of different VGS benefits on their spending decisions to install VGS. Therefore, this research conducted choice experiment to find out building stakeholders’ preferences and willingness-to-pay for VGS. A conditional logit model was used to analyze the data. Based on the results, most of the building stakeholders agreed that VGS provide various benefits such as reducing air temperature, removing air pollutants and reducing energy cooling demand, etc. However, they were mostly willing to pay more for the benefits of stress level and reduction of energy cooling demand. The results assist in the appropriate changes or enhancements to be made to existing policies on VGS to help create more opportunities for building stakeholders to adopt VGS. Furthermore, VGS service providers could also use this information to aid in their pricing of VGS.
