Complex 3D Condensation Risk Analysis
A concern was raised that there would be a risk of condensation around the steel beam. A two-dimensional analysis failed to accurately asses the situation and so a three-dimensional model was required.
To investigate the detail to determine any risk of condensation and explore options to limit or eliminate that risk.
This was a very complex detail with several factors driving the risk.
The structure was composed of heavy steel elements
The window system was aluminium frame
The beam penetrated from the interior to the exterior at the top corner of the building, this three-dimensional corner amplified the problem
The roof was composed of an unusual steel and rubber sandwich deck
An in-depth knowledge of building physics and material heat flow was required to correctly identify the issues.
We first build a series of two-dimensional models to get a sense of the geometry of the detail and see where the main risk of condensation was likely to be.
We converted these models into a complex three-dimensional model and viewed the model from various angles and at differing depths in order to determine which drivers were causing the condensation risk.
Having achieved this we then ran a series of engineering variations to bring the condensation risk into an acceptable level.
With close co-ordination with our client the condensation risk was finally reduced to an acceptable level.
