Previous studies have been carried before this project on TRNSYS 16. My goal is to model a building on TRNSYS 17 that has already been modeled on TRNSYS 16. After modeling exactly the same building and the same gains (internal, occupation, infiltrations...), I am supposed to find the same results or approximately the same results than the studies that have been carried on TRNSYS 16. I found that the heating loads were almost identical between the two versions but the cooling loads are twice lower in my version (TRNSYS 17) than the previous version (TRNSYS 16). I checked the building file and the .dck file and I cannot see a difference between the two versions except for the building file. The only difference comes from the four new inputs in type 56 in TRNSYS 17 that I connected to the weather file. I suspect the mistake to come from the solar radiations but I cannot find why. I would like to know if something similar ever happened to you and if you have any hints to fix the problem.</span></div><div><span style="line-height: 115%; font-family: "Calibri","sans-serif";"><br data-mce-bogus="1"></span></div><div><span style="line-height: 115%; font-family: "Calibri","sans-serif";">Thank you in advance.<br data-mce-bogus="1"></span></div><div><span data-mce-style="font-size: 12pt; line-height: 115%; font-family: 'Calibri','sans-serif';" style="font-size: 12pt; line-height: 115%; font-family: "Calibri","sans-serif";"><br data-mce-bogus="1"></span></div><div><span data-mce-style="font-size: 12pt; line-height: 115%; font-family: 'Calibri','sans-serif';" style="font-size: 12pt; line-height: 115%; font-family: "Calibri","sans-serif";">--<br data-mce-bogus="1"></span></div><div><span data-mce-style="font-size: 12pt; line-height: 115%; font-family: 'Calibri','sans-serif';" style="font-size: 12pt; line-height: 115%; font-family: "Calibri","sans-serif";">Mehdi Benjelloun<br data-mce-bogus="1"></span></div><div><span data-mce-style="font-size: 12pt; line-height: 115%; font-family: 'Calibri','sans-serif';" style="font-size: 12pt; line-height: 115%; font-family: "Calibri","sans-serif";">Centre Efficacité Énergétique des Systèmes <br data-mce-bogus="1"></span></div><div><span data-mce-style="font-size: 12pt; line-height: 115%; font-family: 'Calibri','sans-serif';" style="font-size: 12pt; line-height: 115%; font-family: "Calibri","sans-serif";">Maitrise de la Demande en Énergie<br data-mce-bogus="1"></span></div><div><span data-mce-style="font-size: 12pt; line-height: 115%; font-family: 'Calibri','sans-serif';" style="font-size: 12pt; line-height: 115%; font-family: "Calibri","sans-serif";">Mines ParisTech<br data-mce-bogus="1"></span></div></div></body></html>
