Re: [TRNSYS-users] trnsys economics
Dear Jurgen,
This seems to be a problem with the proformas. Please find attached new
version of the proformas. You have to replace them in the directory
\TRNSYS16\Studio\Proformas\Output\Economics\Detailed
Analysis\Type29b.tmf and
\TRNSYS16\Studio\Proformas\Output\Economics\P1,P2 Method\Type29a.tmf
Best regards,
Diego

Hello everybody,
I have some problems using type29a and type29b. The list file reports an
invalid number of parameters.
In the documentation there is no reference or example.
Does anyone have a project/example using one of the two components?
Thanks (in adv.)

TYPE 29 is called only twice in each simulation, once at the beginning of the simulation to check its parameter list, and again at the end to perform a standard life cycle cost analysis based on the simulation of one year of solar system operation. It compares the capital and back-up fuel costs of a solar system to the fuel costs of a conventional non-solar system. It is assumed that the solar back-up system is identical to the conventional heating system, in that only the incremental costs of adding solar to the conventional system are considered.
The detail of the economic output is dependent on the mode and parameters used. In this instance (Mode 2) various economic parameters are used to calculate the yearly cash flows, life cycle costs, life cycle savings and payback periods. It also provides the user with options to calculate the rate of return on the solar investment, to consider income producing buildings, and to include federal and state tax credits.
