Perceptions of participants on key enablers.

Superordinate Categories	Categories	Examples of selected quotes
Motivation	Compliance with green initiatives	“So I think if this is successful, so this could be one point that we can gain for this GBI point.” (Interview session 2) “We use this solar because of this GBI. Otherwise we won't.” (Interview session 6)
	Promote Corporate social responsibility (CSR)	“Solar can help reduce carbon emission” (Focus group session 1) “But I also support it because like it's a good step in terms of environment.” (Focus group session 7)
	Dual functionality	“I would say the reason why we're doing this is because we're trying to utilize space or area that is exposed to sunlight that is not used right now.” (Focus group session 1) “So they can use existing road to generate more energy, save the carbon emission.” (Interview session 6)
Opportunity	Financial incentives	“I think last month the UOB bank launched a U-Solar package. So I think UOB acts as a bridge, bridging this with the end user and solar panel provider.” (Focus group session 2) “For the industrial, if let's say you install the solar, you will get some investment tax allowance from there, so this is an encouragement also.” (Interview session 5)
	Sunny climate	“In Malaysia case particularly, we are near to the equator, so this is all the advantage we are having.” (Focus group session 4) “Any country along the equator is actually having the best irradiance on the flat surface.” (Focus group session 7)
	Increased environmental awareness	“I think people are more and more aware of this kind of environmental benefits from using solar.” (Focus group session 7) “People have started to get some awareness on solar. Also one of the reason our MESTECC1is pushing for renewable energy. So it is a good time to promote this solar paver.” (Focus group session 7)
Ability	Green experience	“One of the projects landed was doing GBI, basically you need to consume less than 1000 kW of light, that's why end up one of our ABC jobs is basically all solar lights to achieve the GBI rating.” (Focus group session 1) “So for landscape aspect that we had to propose some planting that can last for case drought tolerance. That mean that it requires less water. We will also work together with M&E engineer. They have to design a rain harvest water tank that can do the water irrigation for the plantings.” (Focus group session 2)
	Experts network	“It involves a lot of trade from architects to mechanical to civil to structure.” (Interview session 6)
	Familiarity with solar technology	“In terms of solar panels, we adopted some. We have parks and we are actually very keen on adopting green technology including solar pavers.” (Interview session 1)
