It is the most extensive green roof in Lublin, designed to cover 16,700 square meters rooftop area of the shopping mall 'Castle Terraces' (Tarasy Zamkowe). Its purpose is to serve as a green recreational area for relaxation and public events, as well as an ecological solution for heat mitigation and water retention. The roof is divided into two parts: 1) an area accessible to the public with flower meadows, walking paths, viewing points from which the visitors can see Lublin’s old town 2) ‘intensive cultivation area’ with endemic trees, bushes and succulents which are not directly accessible to the public [1,2,3,8].

Focus

Creation of new green areas

Project objectives

The basic premise of the project was to create an open access, large, green space on the roof of the Castle Terraces, that would refer to the natural riverside landscape of the nearby Bystrzyca river valley and aid with the reduction of the heat island effect and help with water retention [1, 3, 8].

Implementation activities

The project introduced a green roof of the total area of 16,700 square meters – with around 5,000 square meters being accessible by the public and the other 10,000 square meters serving as an intensive cultivation area for the endemic greenery. -The cultivation area to be established on the 15 cm thick soil substrate. -The ‘garden parts’ of the roof to be planted on the 42cm thick soil substrate. -The trees to be planted on the 80-140cm thick soil substrate [1,2,3]. Plants to be selected to create an endemic ecosystem of regional character. The following Optigruen green roof products to be used for the construction of terraces: - Optigreen Slip-Separation Foil PE 0,2mm - Optigreen Drainage Mat FKD 10 - Optigreen Drainage Mat FKD 25 - Optigreen Filter Fibre Type 105 - Optigreen RMS 300 absorbent material - Optigreen Kombi control boxes - Optigreen Perforated angle type ZP 120 [1,2].
