[Bldg-sim] Load Calcs with Energy Simulation Software

[Varkie Thomas]

Trane's TRACE700 and Carrier's HAP4 Energy programs can also be used independently for loads calculation.  The DOE2 based energy programs can be used but they are clumsy for loads.
Automated Procedures for Engineering Consultants (APEC) first released its Loads Program called Heating & Cooling Calculations (HCC) in 1966.  It has been updated over the years until around the early 1990s.  The last version is called HCC-V version 3.0.  HCC-V has a forms (not MS Windows) interface and is easy to use.  In my opinion this program is still good enough for design loads calculations which is used to size ducts, pipes and equipment.  
APEC was a consortium of M-E and A-E design firms that funded the development of M-E software.  Around 2004 APEC folded up.  I bought out the APEC Loads, Ducts & Pipes programs as mementos-souvenirs since I was involved in fixing bugs and providing customer support in 1969-70 - my first career job out of college.  The programs come with good supporting documentation.  The Ducts and Pipes programs are DOS based, and the network has to be defined with numbered sections.  They are not worth using since such programs should be CAD based.   
There are plans to put up the APEC HCC-V program for free download on a website.  
The problem is the program comes on two 3.5" diskettes.  Using a diskette drive (Drive-A) you insert Diskette-One and run "setup.exe" and then you get a message saying insert Diskette-Two into Drive-A.  I cannot get the program to install from Drive-C or from the CD drive by combining the the contents of both diskettes into one folder and running "setup.exe" because it still asks yo to insert Diskette-Two into Drive-A.  I tried sending the fully installed program to another computer but there is an error message (DLL) when you try to run it from the other computer.
Does anyone know how to fix this problem?  I can send you the contents of the two diskettes in two folders.  Those who have 3.5" diskette Drive-A (about $40 for an external drive) can copy the folders into two diskettes and install from Drive-A.  There are plans to put up other information (for educational purposes) on the website for free download.  This will include project case studies using DOE2.1E, eQUEST and other programs.
