INVESTIGATION ON THE GROWING CONDITION OF WALL PLANTINGS AND EXPERIMENTS ON THE GROWTH OF WALL PLANTINGS IN VARIOUS GREENING UNITS IN PUBLIC CULTURAL FACILITY WITH LARGESCALE GREEN WALLS

We measured the thermal environment of green walls in one public cultural facility with large-scale green walls. It was found that the temperature of the frame of the greening unit rise as high as almost 45 degrees and the temperature fluctuated above 40°C in the daytime. This indicates that the temperature exceeds the upper limit at which plants can grow normally. After the measurement, we experimented to confirm the possibility of avoiding poor growth of green plants by adding special specifications to the existing greening frame in order to control excessive incident solar radiation.
