TRNAUS 15 is an extension package to TRNSYS15. Whilst TRNSYS15 was made obsolete in 2002, the development of TRNAUS15 has continued to 2026.
Whilst the source code for TRNSYS is normally open source when the relevant package is purchased, the source code for the TRNAUS15 extension is not open source. Users can enjoy the functionality of the developed types as detailed within the TRNAUS15 manual, however they can not extend the source code independantly.
The security of TRNAUS15 source code is paramount to ensure the assessments of energy savings and thus the relevant rebate schemes remain robust to audit and financial reward.
The supply of TRNSYS15 that is required to use TRNAUS15 is available to purchase from Energy AE as the Australian/New Zealand distributors of TRNSYS.
