| 1 | Question from Dr. Arlina Binti Ali | What is the performance testing? | Answer from presenter | The performance testing for this early project stage is limited to the reversible tuning operation and light transmittance measurements for various states of the novel shading mechanism, mainly to demonstrate the working principle. |
| 2 | Question from Dr. Hamdi Muhyuddin Barra | Can ETFE foil be used to control the amount of transmitted UV and IR radiations? | Answer from presenter | Yes, ETFE can e used to control UV and IR radiations. Even though ETFE is a highly transparent material on a wide spectral range (one of it's prime characteristics), reflective coatings and also tints (coloring), can be used to achieve optical characteristics comparable to glass. |
| 3 | Question from Dr. Hamdi Muhyuddin Barra | You mentioned that the light transmittance is 22.9% when it is fully inflated or in open state. Is there a way to increase this value? | Answer from presenter | Yes, the goal is to expand the tuning range. This can be done by optimising the cushion geometry, frit print pattern and properties and print density of the frit coating. |
