Hello, I'm studying EnergyPlus and made two-story house model by sketchup. I'm using EnergyPlus to calculate temperature, heating energy and electric power consumption.

I put AC(25℃) 5hours and put internal gains (light, people, electric equipment) and simulated. As a result, AC worked correctly, but "HVAC electric demand power(W)" was strange. I thought electric demand power get big when AC is working, but it didn't change at all. Then I thought ventilation making HVAC electric demand power too high, so I deleted ventilation once and simulated again, but it also didn't change.

Could somebody tell me which option making an effect to HVAC Electric demand power? And tell me how to decrease electric power consumption of HVACs? (In my present simulation result, HVAC electric demand power is about 1119～1120W/h)

How to calculate HVAC Elecrtic demand power correctly? Hello, I'm studying EnergyPlus and made two-story house model by

Hello, I'm Japanese student majoring in Architecture. I'm using EnergyPlus to calculate inside temperature and sensible cooling energy of model house that made by SketchUp in my own. I set materials, constructions, HVACs, internal gains( lights, electricity, people) and simulated, but some of inside temperature became too high. (Ex. outside temperature 26℃, inside temperature 52℃)

First, I thought it caused because I put wrong number to materials(conductivity, thickness or more), so I changed number and tried simulate again, but its results were still too high.

Could someone tell me possible causes that makes inside temperature relatively high than outside temperature?

P.S. I'm so sorry about using poor English to ask these Questions because I'm not native in English.

Thank you very much for giving me comments. My simulation details are below. Lights: using schedule on/off ZONE1,6
