Get some live feedback, get some pointers Or you have a question that doesn't really warrant a post: too simple, too vague, just want a pointed? Or maybe you just miss the 90s? Maybe keeping up an IRC channel wouldn't be such a bad idea? Maybe you have a better, 21st century alternative to propose? |

2024-01-05 09:18:37 -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? |

2023-10-23 13:49:28 -0500 | marked best answer | Model dynamic electrochromic glazing in EnergyPlus EnergyPlus has an object called WindowProperty:ShadingControl that accepts a "Switchable Glazing" option, and then you define a switch point, such as solar radiation: below it's fully clear, above it's fully tinted. This is fine and easy to setup for a binary case (fully clear/dark). As stated in the documentation: "When a shading device is present it is either retracted or activated. When it is retracted it covers none of the window. When it is activated it covers the entire glazed part of the window (but not the frame)". How do you go about modeling a dynamic electrochromic glazing, when the glazing can take any given state in between fully clear and fully dark? 1.Is it possible to have some interpolation in between? Something along the line of this (which is from eQuest's help file): 2.If not, which is what I think, I'm ok defining 4 or 5 intermediate steps (should approximate good enough). I think I'll use an EMS program to do that (would love to be proven wrong/have just missed a built-in function), but I'm unclear what variable would be equivalent to the "solar radiation". I'm guessing "Surface Outside Face Incident Solar Radiation Rate per Area". Is that correct? |
