6.1.3 Building Elemental Performance

2 minutesread

This area will display notional thermal values for the mass model.  The values set in the chosen Energy Code are displayed at the top of each panel.  Values may then be input or adjusted for each element.  These will simulate actual properties in the model.

The values input in the Building Elemental Performance panel for Roofs and Floors will affect the Maximum Façade Performance.  As the values for the Roof and Floor are improved, the Maximum Façade Performance will reduce to indicate those Façade elements should reach this level of performance.

As the thermal properties for Walls or Glazing elements improve, more glazing will be allowed.  This can be seen in the Maximum Allowable Glazing slider.

The Selected Facade Performance provides an indication of the effect on Maximum Allowable Glazing.  Improved performance will require less glazing in the Façade and this is indicated by the Maximum Allowable Glazing reducing as the Selected Façade Performance increases.

Selected Facade Performance For Mass Models

In imperial models, thermal values for all elements (except glazing) are given in R-values.  Only Glazing Properties are shown as imperial U-values.

In metric models, all values (including glazing) are shown as metric U-values.

For Conceptual Mass Models (imperial and metric), since there are no building elements in the model such as floors or walls, the values shown are simulated element properties.  No properties are written to the Conceptual Mass Revit model.
