<p class="MsoNormal"><span lang="EN-US" style="font-family:"Arial",sans-serif;color:black">I would like to ask advice regarding which simulation tool would best suite our needs. We are an engineering bureau in Zürich, with long years of experience in building
simulation. We deal with: load calculations, comfort evaluations, daylight, natural ventilation, HVAC optimization, LEED certification or support in development of innovative energy concepts.

<p class="MsoNormal"><span lang="EN-US" style="font-family:"Arial",sans-serif;color:black">Our current tool is TAS from edsl, which has large benefits in 3D-modelling, fast and stable calculations and user friendliness, but is lacking regarding HVAC modelling
(geothermal concepts, European market oriented systems) and has flaws regarding solar shading and natural ventilation controls.

<p class="MsoNormal"><span lang="EN-US" style="font-family:"Arial",sans-serif;color:black">It is very clear that there is no “best” simulation tool, but very difficult to guess which one is best for us. I can read summaries of features and watch video tutorials,
discuss with customer services, which I am doing, but the most useful input is from the user side. I am hoping I can get some recommendations here.<o:p></o:p></span></p>
