<div><div>Madeline,</div><div> </div><div>a lot of software might claim to do all these things. But between claiming and actually providing good estimations is a world of difference. The main issue is that computational power is not at the level where a building cna be subdivided in a trillion nodes that can each be calculated simultaneously. What is the current general approach is that a zone or a building material is considered as a single node, sometimes the zonal air is subdivided in multiple nodes. </div>
<div>To give a good estimation regarding your moisture transport I assume it is crucial to have an accurate calculation of zonal surface temperature. And that is extremely difficult: transmission in the building structure can be wel modelled, radiation could (at least theoretically, but of course things change as soon as the room is furnitured, decorated and people are using it) and convection is an even bigger problem.</div>
<div> </div><div>I would start with some recent projects on heat air and moisture transport, where ESP-r had been coupled to Fluent (If I remember well). Check for IEA ECBCS annex 41. I am sure they have done some analysis of available software and based their selection on potential to perform the task at hand.</div>

I am looking for an energy simulation programm that calculate heating and cooling loads, moisture transport and where natural ventilation can be activated. The software should (if possible) also have a bank for structural steel componenst such as steel joist, decking... or other structural component that are used in high-rise construction.<br>
<br>
I use to work with DEROB-LTH (swedish software), but it does not take into account moisture transfer, and I am looking for something more efficient and developped. I was thinking of TRNSYS, Energy plus or ESP-R. Does anyone have other suggestions ordoes anyone has used these software and could tell me if they respond to my criteria?<br>
<br>
Thank you<br>
