Abstract
Laws and regulations require that energy needs, indoor climate and moisture safety should be estimated and analyzed during the design phase, before a house is built. Available tools to predict the hygrothermal conditions need, in general, hourly exterior and interior climate boundary conditions. Available climate data sometimes consist of periods with incomplete or lack of data.
The aim or this paper is to present methods in order to supplement periods with lack of data and methods in order to create diffuse, direct and long wave radiation. Presented methods to supplement and create climate data was tested in a case study in a wood frame roof.
The importance of using reliable climate boundary conditions in order to estimate the hygrothermal conditions before a house was build is presented. It is shown that real climate boundary conditions need to be used to reach correlation between measured and calculated hygrothermal conditions. The need for reliable climate boundary conditions for dimensional purposes and that WUFI 5.2 can be used in a reliable manner when calculating hygrothermal conditions in wood frame roofs located in Northern European climate are shown.
