- The applicant's environmental report says emergency generators are in enclosures, with rooftop solar panels expected to cover about 20 percent of the energy need of the occupied building.
Permission date is the signed order date on An Coimisiun Pleanala's case page. The environmental report states no MW figure, and its floorspace figures are inconsistent, so only the eight-hall description is used.
