| - | The first test that will be executed regarding the dome is a simulation in a calculation program called PowerFrame. In this program the wind load on the structure will be tested. For this test Eurocode 1 of the building rules of the European Union will be used. After the test, the section of the beams will be optimized. | + | The first test that will be executed regarding the dome is a simulation in a calculation program called PowerFrame |
| The other functional tests will be executed on the prototype of the automatic window. The first test is the building of the prototype itself. The team will rate different aspects while building the prototype. In this way the weak points of the design of the prototype will be detected. For every weak point, improvements will be formulated. | The other functional tests will be executed on the prototype of the automatic window. The first test is the building of the prototype itself.
