What kind of graphic is this? The graphic is a comparative representation of different window sections and the effect of environmental factors on them.


What are the primary inputs of the analysis that the graphic describes?  

Climate Data, Window section detail/material, conductivity of Materials

List the primary outputs/metrics that the graphic describes?  

Temperature difference through window section, dew point, effective U value and condensation risk location

What is this graphic showing? 

The graphic portrays window section options in isometric and envelope heat transfer through those options at different winter month temperatures. It depicts the risk of condensation in each of the options with effective U-Values of construction.

How did you make the graphic? 

Rhino was used for modeling and rendering the mullion detail sections. Therm combined with Ladybug-Honeybee for the envelope heat modelling and condensation risk analysis. Post-simulation using Photoshop and Bluebeam.

What tools did you use to create the graphic?

What specific investigation questions led to the production of this graphic?

What happens to the renovated laboratory spaces in an existing building, over differing humidity? Would it lead to condensation inside the Lab Space? How can we reduce energy loss through the exterior enclosure while maintaining the minimal vertical mullions?

How does this graphic fit into the larger design investigations and what did you learn from producing the graphic?

Since, it is a retrofit of existing strip windows on historically significant mid-century modern building, the design / construction team identified costs associated with different treatments, and design leads considered the visual impact of different thermal interventions on the existing exterior envelope fabric.

What was successful and/or unique about the graphic in how it communicates information?

It clearly shows the different options all in one graphic, for ease of comparison between environmental factors and visual aesthetics.

What would you have done differently with the graphic if you had more time/fee?

We would have integrated with an energy model of the space for studying the energy use impacts of the building envelope.
