<p class="MsoNormal"><span lang="EN-US">Hi,<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I use TRNSYS to model an office building (new construction, good insulation) and check the comfort inside.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I would like to verify the surface temperature of the floor of each zone. So I use the build surface outputs 17 TSI and 18 TSO.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The set temperatures are 20°C during the day and 16°C during the night.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The surface temperature of the floor seems to be very low sometimes : 2°C or 3°C below the set temperature.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I already checked the ventilation, infiltration, heat temperature, temperature of zones nearby.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Did you already observe this kind of results ? Do you know why ?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>

<p class="MsoNormal"><span lang="EN-US">Thanks<o:p></o:p></span></p>
