In the following three settings (shown with photos; Fig.10), different level of plantation has been adopted in the design of each building space where the A is a normal office with zero level of plantation, and B is a hallway with medium plant coverage, and finally the C shows the maximum green percentage. • Rate the following photos considered as comfortable environment (Fig.10). -A -B -C Figure 10: Level of plantation; A (zero level), B (medium level), and C (maximum level) Table 10: The data of the cell growth and substrate loss 1 2 3 4 5 Standard Deviation Responses Weighted Average A 27 (35.53%) 31 (40.79%) 14 (18.42%) 4 (5.26%) 0 (0%) 12.22 76 1.93 / 5 B 0 (0%) 7 (9.21%) 21 (27.63%) 29 (38.16%) 19 (25%) 10.36 76 3.79 / 5 C 1 (1.32%) 1 (1.32%) 7 (9.21%) 25 (32.89%) 42 (55.26%) 16.03 76 4.39 / 5 3.37 / 5 7. How to Utilize Indoor Plants 7.1. To Improve Indoor Air Quality This part of the paper will be advising on how to apply the greenery method and how to use the plants in indoor spaces, and that is by answering the following two questions; how can a designer or a normal person choose a plant for their residences? and how many pots they can use? How to Choose a Plant? It is important to refresh the indoor environment by natural elements as they have the power to remove chemicals within a space (Kobayashi et al. 2007). The table below (Fig.11) lists evaluations recorded for some plants from 1 to 10 scales, for its capability, to reduce hazardous chemicals. In addition, further information on each plant is provided that can help the designer to pick out the suitable plant for their designs as shown in Figure 11. 842 ZEMCH 2015 | International Conference | Bari - Lecce, Italy
