Abstract [en]

The following article consists of two parts; one part is about house construction and the other is a specialization about radon. The house construction part describes how to project a house from start. It contains the conformation of the house, the installations needed, calculations considering the strength of the construction, energy calculation and what materials were chosen. Calculations considering the costs of building and operate the house has been carried out. The result showed that the house would cost approximately two million Swedish kroner to build and thirteen thousand kronor a year to operate. We feel very happy about the resulting house and content about the fact that it fulfills all the demands of BBR19.

The specialization about radon is integrated in the article as a report from a consult considering the radon emanation in the house. The report has a wide informative base about what radon emanation is, how it works and what laws there are in the subject. The specialization of the report is about a quite current topic; when we have stopped using aerated concrete in houses, are there still risk that ordinary concrete emanates radon and gives of radon gas in our homes? Is it possible to reassure that this does not happen? What we have concluded is that it is very likely that the concentrations of radon in a room will be high if the wrong kind of ballast is used in the concrete. It is possible to reassure that this does not happen, but at the moment there are no clear guidelines about tolerated values from building materials. Also there is yet no money to earn by doing quality controls on ballast. If the demand for radon safe ballast increases due to a gathered effort to lower the requirements considering radon concentrations, the development of quality controls will go faster.
