The awareness and attitudes of stakeholders are crucial for the development of green roofs and green walls. The aim of this article is to analyze the awareness, opinions and attitude of respondents from Sofia, Bulgaria regarding green roofs and green walls, as well as the willingness to pay (WTP) for these types of green infrastructure.
A direct consumer survey was conducted, containing 17 questions regarding sociodemographic characteristics of the respondents, awareness/opinions about green roofs and green walls and WTP. A total of 100 respondents participated in the survey.
The most well-known benefit was the air purification, selected by 73% of the respondents. The biggest concern was the maintenance cost, selected by 65%. The increase in biodiversity was perceived more as harm than benefit and 58% were concerned about a possible invasion of spiders, insects and birds.
Most of the respondents (93%) consider it necessary to build green roofs and green walls. Depending on the type of greening, between 73% and 78% of the respondents would pay more to live in a building with a green roof or green walls. There was no correlation between the sociodemographic characteristics and WTP.
