2020-05-26 10:35:48 -0600 marked best answer Contradiction between cooling load and u- value of glass

I'm simulating in EnergyPlus a room to analyze different measure to reduce the energy demand. I changed the U- value of simple glazing system, from 5.8 to 3.3 to 1.4, with the same solar heat gain coefficient of 0.8. I thought the cooling demand would have incremental reducing, but it is the opposite: When i have lower u-value, i obtain higher cooling load. I'm working with cooling ideal system. Is there something I am doing wrong? should i check another parameter? i really will appreciate your suggestions.

I'm trying to define in OpenStudio Space Infiltration Design Flow rate, by using a design flow rate parameters of a buildings similar to my study cases. My reference data have the results with 50Pa of pressure difference. I read the engineering reference and don't see any limit to the pressure use for that. (For the case of Effective Leakage area, it is well defined that should be 4Pa) Can i use a flow rate of 50Pa for the simulation? I hope anyone can help me,

I want to model a double windows with its outside layer with wood venetian blinds. I thought that with blind-window-material in Open Studio shoul be the solution, but then i saw an image image description, where is explained that the software assume this material inside the glass layer, and i would like to put outside.

I'm trying to modelated a building in OpenStudio, but i can't understand where i have to define the influence of the surrrounding on the envelope heat balance. For me looks like that the shading surface, have only influence the shade, but not in the solar radiation reflection. There is any option in OpenStudio where i can define the surroundings features? I would be thankful for any suggestions about it. I'm reading for understand the software the EnergyPlus Documentation Engineering Reference, in the chapter 6 it is explained the solar radiation reflected, but my question is there is any step that i have to follow to define it in OpenStudio?
