"gugler! build & print triple zero" - subproject 3: recyclable constructing
This project is a sub project of the flagship project "gugler! build & print triple zero"
The long term goal of building is to integrate the entire cycle of building, starting with the production of building materials and components and the provision of energy, going on with the use of the building and finally its disposal into a global concept of sustainability. This also means that this cycle shall be fed only by substances that can be replaced during the course of their life on earth and / or can be biologically degradated (Nawaros) or can be completely recycled (recycros).
In order to achieve that goal it is not only necessary to use raw materials that already have been recycled (see subproject 2 "recycros") but also to apply construction methods and joint techniques (material inherent bonding) that allow recycling - regardless whether recycled or new materials are being used.
The close examination of these conditions, a compilation of general rules for recyclable engineering, the development of highly recyclable structures and a selection of possible constructions for the c2c-demo-building are the subjects for this subproject „recyclable designing“.
Together with results of other sub-projects the results of this subproject will establish the basis for the selection and calculation of the design-principle and the constructional elements to be used for the eco-effective factory building Gugler in Melk.
The first work package is the research of state-of-the-technology concerning demolition and dismantling of buildings and the conditions and weaknesses, of joints and bonding techniques regarding recycling, of state-of-the-art-projects, of potential improvements for the dismantling and recycling in the field of building and the estimation of the actual need for action and the actual possibilities.
On this base and with the results of the Best Practice research we put up general rules for recyclable construction design and after analysing existing constructions concerning recycling recommendations for recyclable design.
One part of the result is a selection of constructions that allow a high percentage of recycling (the aim for the demo-project is 95%). These possible constructions are being optimized in a feedback process that involves ecological benchmark, calculation of building physics and structural engineering and the possibility of actual implementation in the construction process.
The consideration of introducing materials in a process of up-cycling –which means materials being reused allowing the same (high) quality demands - is particularly important to make a step towards the principle of cradle-to-cradle.
The proposed solutions and the technical and ecological specifications will then be compared to standard-solutions. This will lead to conclusions about the extent of possible ecological improvements.
Recycling possibilities will also be determined for the building services gear concerning used materials and components and the possibilities of their recyclings
In the last step the results of subproject 2 (building with "recycros") about recycled raw materials will be incorporated in the results of subproject 3 („recyclable designing“). The results concerning ecological benchmark and calculation of building physics in combination with the results of subproject 2 lead to a catalogue of possible constructions with the high percentage of recycling which is aimed for he demo- project (95%)
This selection is the basis for sub-project 5 "eco-effective building" and as a consequence the basis for the design of the Gugler-Demo-Building.
