Cooling Design Detailed Results

The 'Analysis' tab has detailed half-hourly cooling design results (displayed as a line graph by default).

 

For more on how the output is calculated see: Calculation of DesignBuilder Output from EnergyPlus Report Variables.

 

 

For windows without an interior shading device this heat flow is equal to:

 

+ [Convective heat flow to the zone from the zone side of the glazing]

+ [Net IR heat flow to the zone from zone side of the glazing]

– [Short-wave radiation from zone transmitted back out the window]

+ [Conduction to zone from window frame and divider, if present]

 

Here, short-wave radiation is that from lights and diffuse interior solar radiation.

 

For windows with an interior shading device this heat flow is equal to:

 

 [Convective heat flow to the zone from the air flowing through the gap between glazing and shading device]

+ [Convective heat flow to the zone from the zone side of the shading device]

+ [Net IR heat flow to the zone from the zone side of the glazing]

+ [Net IR heat flow to the zone from the zone side of the shading device]

– [Short-wave radiation from zone transmitted back out the window]

+ [Conduction to zone from window frame and divider, if present]

System Heat Flows (Compact HVAC only)

These heat flows are plotted on the System Energy axes:

 

 

Surface heat gain data refers to heat transfer from the inside surface of the building elements to the zone.
