Our project has a very limmitted vegetation area on the grounds because the building footprint covers almost the whole site.There are only some small parts of vegetation covered with grass and some shrubs. This would cover only around 1% of the site. Additionally, there is also vegetated roof but if we add it to the green areas on the grounds it will still be less than 5% of the project site. Is our project eligible for this credit? Does the 5% limit refere only to sites with no ongroud vegetation?
