<div>Hi, everyone,</div><div><br></div><div>In my experience, 160 hours working time is only for design submission, for a mid-complex building. </div><div><br></div><div>There are something maybe happen which cost a lot of time:</div>
<div><br></div><div><ol><li>Most of time the client and also MEP partners will compare the building loads between energy model and MEP partners calculation. The modeler need to find the calculation difference, and figure out why this would happen and how to fix.</li>
<li>Architect and MEP partners will ask the modeler to do parametric studies to compare options. The modeler need to run the model - sometimes there will be some issues which also need time to solve.</li><li>Client wants to know the effect of each energy saving strategy. The modeler need to do a lot of runs to make clear about this. And also there will be some problems happen, modeler need time to solve it.</li>
</ol>After received the comments from USGBC, it depends on how many comments you get. Normally 40 hours around to answer those questions if the model has no big mistake or missing.</div><div><br></div><div>In the end there should be some extra hour for safety which depends on the complex of the project.</div>
