2019-02-22 09:07:54 -0500 marked best answer Revision control for text-based modeling programs

When you're using EnergyPlus or eQuest for example, your input file is a simple text file. During the course of a project, you'll often end up modifying your input file over and over again, as part of an iterative process, be it to debug, calibrate or improve accuracy.

Before long, if you haven't been really careful about backing up and naming files and keeping a list of the changes you've made in another file, you'll be crawling under a sea of poorly named files, unable to know what changes you've made between this and that files.

This is no different than writing computer code, and the programmers have tools to deal with version control / revision control / source control. I could quote Apache Subversion (SVN) and Git for example.

According to wikipedia, Revision control, also known as version control and source control is the management of changes to documents, computer programs, large web sites, and other collections of information. Each revision is associated with a timestamp and the person making the change. Revisions can be compared, restored, and with some types of files, merged.

It's a very handy thing: you'll get a complete track record or what you made (you can comment on what the change is too on some tools), rollback capacities, compare capabitilities, you can fork (for an ECM for example), etc.

Have people being using Revision control with success? What tools have you been using? (eg: Git/Github, TortoiseSVN, etc) How did you set them up to suit your modeling workflow?

2018-12-20 04:35:38 -0500 marked best answer Estimate Fan pressure rise from ESP

In EnergyPlus, Fan Pressure Rise is an input to most fan objects (e.g: Fan:ConstantVolume).

MEPs will usually give you External Static Pressure (ESP), and rarely Total Static Pressure (TSP).

Since what you should input in E+ is TSP (correct me if I'm wrong), are there any rules of thumb to estimate it from the ESP and basic knowledge of what filters and coils you have, or BHP? That would be useful In early design phases.
