Revision history [back]

I am using the DOE prototype large office model (A90.1 2013) and changing just the glass alone to understand the HVAC sizing and energy impact with switching to different glass types. I see that the equipment sizes especially the Chiller and the cooling tower remains the same. Maybe am I missing something? or since the prototype model has a data center in the basement floor, glazing is having no impact?

Why is there no savings (HVAC) even when compared to a single pane glass? I have attached the E+ files(V8.9) for your reference- https://drive.google.com/drive/folders/1IcMf8h8shk42A-5UeoPQMamm2tYFia08?usp=sharing

Thanks
