Initially, I introduced a water-water Heat Pump ( Default Water Source HP) with a thermal storage with the option “none” and a Heat Rejection with the option “Condenser Fan for Heat Pump”. With these definitions selected, the results of the simulation in Energy Consumption report Summary came back blank, without any value.</font></font></span></p>

When I ran the simulation, after these changes, the energy report summary started displaying results without any problems. The modifications made are as it follows: In the library editor, cooling equipment, selecting the heat pump I’ve created, in the “Unloading curves option–Ambient modification” I changed “Wshphi - Amb Mod” to “Air to Air Heat Pump - Amb Mod” in primary and “Wshphi - Amb Mod 2nd” to “Air to Air Heat Pump - Amb Mod 2nd” in secondary. The thermal storage stayed with option “none” and Heat Rejection with the option “Condenser Fan for Heat Pump”. </font></font></span></p>

In attachment I’m sending two TAF files, one before the changes and one after the changes. I find it hard to believe that these simple modifications could have made/cause the difference/problems in the way the Energy summary reports are presented.</font></font></span></p>
