Introduction

Recently I received a question on how to create a custom fenestration element in SANSCalc Desktop to be used as a windows type. A need to create your own custom component will arise if you want to use specific supplier’s windows and doors. Many suppliers have window and door products tested by CSIR and their U-and Solar Heat Gain values have been set.

Using this information, you can add this custom item into SANSCalc Desktop and use it to assign U and SHGC values to the glazing and frame types for a window or door.

Process

The process is very simple. Open SANSCalc Desktop Application and make sure you have a fenestration element created. In the example below I have added a Window element called W1.

Now find the ‘Glazing’ column and and select the cell and down-arrow. In the list, at the bottom is a Custom field. Select Custom.

Then do the same for the ‘Frame Type’, selecting Custom.

Once you have selected these Custom fields the U and SHGC values are ‘open’ so you can then add your own value into these cells. In this example I add 0.5 for U and SHGC values.

These value are then used in the Calculation to the right.

Multiple Rows

If you want to add the information to multiple rows you can use to Multi selection area.

First select multiple rows by picking the first row on the left column and then Shift-Select the last.

Then complete all the information in the Multiple Area and click Apply. In the example I applied the Orientation.

And then the G and P Values.

And then the Custom items.

The only manual input will be the Mark of the Window, sizes and then the U and SHGC Values.

Also remember to always enter values from left to right in a row. This needs to be done as the calculation on the right only adjust if the value on the left get changed.

And remember to save.

Conclusion

Using the multiple select option allows you to quickly change many rows at once.  And by adding the custom field you can change SANSCalc to work with any Custom Window or door supplier.
