HTflux will give you the information you need for this task.\u00a0 It provides precious information for passive house planners, but it&#8217;s ease of use make it suitable for the whole construction industry. As an example we present a pitched roof junction detail of a timber frame construction. <!--more-->The detail was imported of a CAD software via DXF format, materials were assigned using the drag &amp; drop functionality and the HTflux material database. Once you are done with these steps HTflux can give you plenty of precious information with very little effort, e.g.<\/p>\n<ul>\n<li>automated \u03a8-value calculation (aka &#8220;linear thermal transmission coefficient&#8221; or psi-value)<\/li>\n<li>automated U- and R-value calculation (one and two dimensional)<\/li>\n<li>automated minimum temperature calculation with mold and dew-point temperature calculation<\/li>\n<li>customizable temperature and heat flux views to assess thermal bridging effects<\/li>\n<li>unique Glaser 2d simulation to assess vapor diffusion<\/li>\n<li>humidity view to see relative humidity and condensation spots<\/li>\n<li>vapor flux view to find the cause of the condensation<\/li>\n<li>water vapor partial pressure view to get a better understanding of the hydrothermal aspects of the detail.<\/li>\n<\/ul>\n<p>Once you have this information you can use HTflux&#8217;s drawing function and material database to optimize the details, e.g. change insulation materials, add vapor barriers, change the thickness of elements and so on. Within seconds you will see the thermal and hydrothermal consequences of your optimizations.<\/p>\n<p>Here are the results of the thermal and hydrothermal simulation as an example of the capabilities of the software (click on the images to get higher resolution):<\/p>\n<div id=\"attachment_390\" style=\"width: 677px\" class=\"wp-caption alignnone\"><a href=\"http:\/\/www.htflux.com\/en\/wp-content\/uploads\/sites\/4\/2015\/02\/Timber-Frame-Eaves-Junction-materials.png\"><img loading=\"lazy\" decoding=\"async\" aria-describedby=\"caption-attachment-390\" class=\"size-full-blog-width wp-image-390\" src=\"http:\/\/www.htflux.com\/en\/wp-content\/uploads\/sites\/4\/2015\/02\/Timber-Frame-Eaves-Junction-materials-667x653.png\" alt=\"Timber Frame Eaves pitched roof Materials View\" width=\"667\" height=\"653\" srcset=\"https:\/\/www.htflux.com\/en\/wp-content\/uploads\/sites\/4\/2015\/02\/Timber-Frame-Eaves-Junction-materials-667x653.png 667w, https:\/\/www.htflux.com\/en\/wp-content\/uploads\/sites\/4\/2015\/02\/Timber-Frame-Eaves-Junction-materials-300x294.png 300w, https:\/\/www.htflux.com\/en\/wp-content\/uploads\/sites\/4\/2015\/02\/Timber-Frame-Eaves-Junction-materials-325x318.png 325w, https:\/\/www.htflux.com\/en\/wp-content\/uploads\/sites\/4\/2015\/02\/Timber-Frame-Eaves-Junction-materials-100x98.png 100w, https:\/\/www.htflux.com\/en\/wp-content\/uploads\/sites\/4\/2015\/02\/Timber-Frame-Eaves-Junction-materials.png 1020w\" sizes=\"auto, (max-width: 667px) 100vw, 667px\" \/><\/a><p id=\"caption-attachment-390\" class=\"wp-caption-text\">Materials view of the eaves detail of a timber frame construction.
