<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I am using phase change plasterboard via the active material database and I am using quite a bit of it. I am using it on all internal walls of two rooms in
a house. It makes only a tiny difference to the temperature and I think I am not using it in the right way at the moment. I should be able to see a reduction of 1 or 2k but I am not. What can I look at? can the way I am positioning the material make any difference?
I am trying to have the pcm exposed. Let me know,<o:p></o:p></span></p>

<p class="MsoNormal">you write you can't see "substantial reduction" - but you do see a reduction? You will need quite a bit of PCM for substantial differences (.gt. 1 to 2 K), probably.<o:p></o:p></p>

<p class="MsoNormal">Which PCM model are you using? I think the basic "53" model cannot really take different temperatures for melting/solidification into account.<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
</div>
<div>
<p class="MsoNormal">A simple approach for testing: If you have two otherwise identical surfaces, put the PCM in one and then look at the temperature profiles for a day for these surfaces (or split one of the PCM surfaces into two and remove the PCM from one
of these). This should quickly give you an idea on if something is happening ("something" may be disappointingly small temperature differences).<o:p></o:p></p>
