3.3.4 Analysis of green wall

 So the roof terracing could not reduce much energy as compared to any other landscape technique. Secondly, the vertical green wall:

 Green wall vertically occupies the larger surface area.  Since the south façade receives greater extent of sunlight, the green wall established should be helpful for the energy reduction of the building. 3.3.4 Analysis of green wall All the parts of the modular living wall were pre-developed into modules and were welded on site. The board framework was specifically secured into One PNC Plaza’s strengthened solid brick wall and first framework was mounted on it with a stainless steel sectioning. The living green wall consisted of 602 boards in number. Each board measured 610mm in height, 610mm in width and 102 mm profound. Each board consisted of 24 plants. The planting medium used in the modular green wall was a thick soil-less and was placed in 102mm X 152mm X 102mm aluminium cell, in the inner side of every board.

The plants showed some seasonal variation when the season changes from summer to autumn.

The frame was prepared off-site with the material stainless steel and aluminium. The boxes were made up of stainless steel. The boxes were then placed and fixed on the aluminium wall frame which was further fixed with the wall. The plants were put in the boxes before they were fixed on the wall.
