I guess it depends on your application. </div><div>For me I am modeling phase change envelope materials, so design builder's ability to produce energy plus Editable IDF's makes it the only option.</div><div><br></div>
<div>I am an eQuest user, and find that design builder is the closest in ease of use to eQuest, but provides much more capability. </div><div><br></div><div>My understanding of Trace 500 is that it can do envelope studies, but is a tool created to best serve mechanical engineers, or HVAC specialists. </div>
<div>I have not used energy gauge, and have not run a full simulation in IES-VE,, but do find the interface to be nice. </div><div><br></div><div>What is key is to understand the simulation engine behind the software. </div>
<div><br></div><div>Both eQuest and Trace 500 use DOE 2.2, Design builder uses Energy Plus 7, and their own custom computational fluid dynamics visualization. I believe Energy gauge may and IES-VE both use their own engine (you should check) </div>
<div><br></div><div>Energy Plus is the most compressive tool available, and is funded by the department of energy but does not have an easy to use interface, ( that is where design builder comes in handy) DOE 2.2 is very powerful, but is limited in features and is typically used with eQuest as an interface.</div>
<div><br></div><div>For most projects compliance is the main goal, and visualization of results is second. </div><div><br></div><div>Both Energy Plus ( design builder ) and DOE 2.2 ( eQuest/Trace ect ) are compliant with ASHRAE 140, and can be used for tax credits, LEED projects ect..</div>
<div><br></div><div>Other software sometimes is not qualified to use in compliance, so have less value In many projects. </div><div><br></div><div>Personally I prefer design builder/energy plus over other modeling tools, due to it's ability to model both envelop and HVAC systems in detail, and due to the great support, and the latest has incorporated up to date ASHRAE libraries. </div>
<div><br></div><div>Thanks and feel free to ask any further questions..</div><div><br>Sent from my iPhone</div><div></div></div><br></div><br><br clear="all"><div><br></div>-- <br><div style="text-align:left"><font face="verdana, sans-serif" color="#999999"><i>Jeremiah D. Crossett</i></font></div>
