<div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><div>Dear all,</div>
<div> </div>
<div>I have been trying to simulate a residential building (a typical Dutch row house) with eQuest for my graduation project.</div>
<div>The building is heated up by high temperature radiators which are fed by gas fired boiler.</div>
<div>Balanced mechanical ventilation with sensible heat recovery is the ventilation principle.</div>
<div>In order to simulate the house, I used heating/ventilation default scheme with air-side economizer, heat recovery, baseboards in rooms, supply fan (no return fan). </div>
<div>The air-side economizer is controlled by OA temperature.</div>
<div>Minimum outside air is determined by sum of zone outside air demands.</div>
<div>
<div>However, the simulation results show too high vent. fan electric consumption at around 3100 kWh/year</div>
<div>while I expect them to be around 600 kWh/year, typical for mechanical ventilation with heat recovery. </div>
<div>First question: What would be the reason for this? </div></div>
<div>Second question: In the detailed simulation output file, building loads (LS-D) are around 25 MBTU while </div>
<div>Building HVAC loads (SS-D) are around 6 MBTU. Am I wrong if I expect to see the same values for <br>both as the losses in the building should be compensated by the system.<br>Third question: What is exactly INT SUR in building monthly load component (LS-F)? And is it normal to<br>have values as high as window conduction losses?<br><br>Thanks for your consideration.<br>Sorry for my English since I'm not a native speaker it is not perfect.<br><br>Best Regards<br>Sinan Senel<br>Technical Unversity of Eindhoven<br></div>
