Maintenance

Design the system for a better lifecycle performance

Maintenance consists of reliability, supportability and maintainability. For these 3 parts design tools were given. The reliability rules to be able to perform a required function, in a situation for a specific amount of time. In the case of the hub, one should think of choosing the right material for all weather conditions and reduce maintenance actions by using the right coating for materials and components. The hub consists of wooden benches, a concrete bottom, plastic sides and plastic top.

The maintainability of a system means how easy, quick and safe a system can be restored. This is done by a professional under specific conditions. Guidelines in this field are for example the use of universal applicable components, so that cleaning services of the municipality can access the hub frequently for small tasks. Another example is the modularity of the hub. The hub can be composed out of different parts, depending on the environment and space. When composing the space around maintenance points can also be regulated. The supportability includes the characteristics of the ease of the logistics. In this case, the culture hub company will do big maintenance to ensure there is enough knowledge about the hub.

Furthermore, there are topics that are only applicable on the hub. We designed the hub so that about 20% of the investment cost is put back for maintenance. This is quite high, but the materials of the hub can last for around 25 year, so reuse is intended. The biggest factor is this will be if vandalism is prevented. Solar Panels are considered, also transparent ones. This is deliberately not done, because of higher maintenance costs and bad access to the roof. The performance of the panels would drop by 25% without cleaning. Also the inverter could fail after 5 year, which is a big expense. Instead, a grass in combination with a scented plant is used. The plants isolate well and are simple to maintain. Additionally, pigeons are prevented by the smell. A backup is not needed in the hub. The hub is just connected to the grid of the city.
