Tiivistelmä
The scope of this work is to design, test and compare different floor structures for modular buildings. The requirements for the element are following: it should contain floor heating system (and the layer for pipes, that would not crack and it should be able to spread the heat evenly at the same time), efficient heat insulation; all the elements should have as little carbon impact as possible, and be easy to produce.
This thesis contains two parts: theoretical knowledge about prefabrication and radiant floor heating and practical implementation (structural design of modules, manufacturing, sustainability calculations).
Two different structures were designed and tested in production. The first one is based on thin steel profiles with XPS/EPS insulation between them and concrete screed with embedded pipes on top of it. The second structure is based on LVL-beams covered by LVL-plate and plywood sheets.
Both structures have trade-offs. The concrete and steel structure causes a lot of extra load to the slab, but at the same time, it provides an even heat distribution. The wooden structure is very thin and light, but it has poor heat performance. But both solutions can be enhanced for further use.
