Hi Jean, welcome to TRNSYS! I did one LEED project in TRNSYS, but
unfortunately I couldn't dig up the constructions files. But it's fairly
easy to put together a few centimeters of concrete then add and adjust a
massless insulation layer to match the U-value required. This is what I
do to get a first approximation. As far as I know, ASHRAE doesn't
specify actually constructions for baseline - like what the exact mass
should be, except that it should be "light weight". <br>
<br>
Sorry I can't be of more help, but let me know if there's anything else.<br>

This is typically used in a "baseline" building for the building energy simulation required by the LEED certification system.<br>
Kind regards<br>
