Installation Notes

Uninstall any previous AERCalc version, including the Appdata directory

Before installing this latest version, please uninstall any previous version of AERCalc. In addition, you will need to delete (by hand in Windows Explorer) the "Appdata" directory that AERCalc creates when it runs. This directory is located here:

C:\Users\<username>\AppData\LBNL\aercalc

It is not normally visible in Windows Explorer, so you may need to make it "visible" in the Explorer view settings to "view hidden file, folders and drives"

If you have saved any special WINDOW databases there, make sure to move them elsewhere before deleting that directory

If you do not delete this directory, the new version of AERCalc will not function properly.

Install the latest versions of WINDOW 7.6 and THERM 7.6

Enhancements

Sorting by Column

It is now possible to sort the records in the main screen by any column header.

Many New Fields Have Been Added

Many new fields have been added in both the main screen and also in the export file. See the AERCalc User Guide for more details. A few additions to note are:

  • CGDB ID from the WINDOW Shading Layer Library
  • Manufacturer from the WINDOW Shading Layer Library
  • Material Manufacturer (when relevant) from the WINDOW Shade Material Library
  • AERC ID field which is user-editable and can be used for any type of product specific ID as needed

Only One Air Leakage Input Value

In the previous version, there were two Air Leakage values for a product, one for heating and one for cooling. There is now only one value for Air Leakage.

New Element in Product Naming Convention to Capture Attachment Position

Because the position (Interior or Exterior) was needed for the AERCalc export, that information is now contained in the name of the product. See the AERCalc User Guide for more details. Here is the new naming convention:

<name>::<attachment type><slat tilt>::<attachment position>::BW<basecase window ID>

Multi-core EnergyPlus Simulations

AERCalc now utilizes multiple computer cores when running the EnergyPlus simulations to calculate the Energy Performance values. It will use the total number of cores on your computer, minus 1. So if you have and 8-core computer, AERCalc will use 7 of them to run the simulations in parallel. This significantly reduces the speed to calculate the EP values.

Bug Fixes

Base Window Abbreviation Changed

In the previous version, the AERC base window designation was BW01. It has been changed to be the same as the window names in the AERC technical documentation, resulting in BW-B as the new designation.

Export Includes "Child" Slatted Product Records When They Are Expanded in the Main Screen

In the main AERCalc screen, if you "expand" the records for slotted products (Venetian blind and vertical louvers), so that both the "Parent" and "Child" records are displayed, then all those records will also be included in the export.
