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)
