EnergyPlus - EnergyPlus 9.6.0, Release Candidate 5

RC4 barely started building and I realized that somehow the new deprecation document was being Git-Ignored, so it was missing with GHA tried to make package. Kicking this back off again to get good release packages for testing.

EnergyPlus - EnergyPlus 9.6.0 IO Freeze

OK, I believe this is the IO freeze version of EnergyPlus. All the pull request labeled for the IO freeze milestone have been merged in. There are definitely still plenty of things to do before release happens, but that's what the post-IO-freeze period is all about. Barring something crazy, this is the IO freeze release.

EnergyPlus - Custom Installer #4 for OpenStudio with HVAC Flex Measures

The QtIFW stuff has been resolved in develop. Those workflows are now properly pulled into this branch. The HVACFlexMeasures branch is still quite a ways behind develop, so there is a chance that something is not compatible. But let's see what happens.

EnergyPlus - Custom Installer #3 for OpenStudio with HVAC Flex Measures

Got the QtIFW stuff fixed on develop, so I pulled the workflow rules into this branch. If it fails to build, it's because some other change has been made in the workflows that is causing a conflicted build state. If that happens, I will make one pass to revert all the workflow changes that have been made here and then just tweak the Qt stuff to fix what I just fixed in develop. If that doesn't work then, well, I'm done trying for now.

EnergyPlus - Dummy build

Test QtIFW version 4.1.1 instead of 4.1 and see if packages build. If so, then merge #8842 and delete this pre-release.

EnergyPlus - EnergyPlus 9.5.0

EnergyPlus 9.5.0

The U.S. Department of Energy (DOE) has released EnergyPlus version 9.5.0. There were many bug fixes and prominent new features this release. The full changelog for this release cycle is listed below. For more information about EnergyPlus, please visit www.energyplus.net.

New Key Capability

EnergyPlus 9.5.0 is now thread safe. A massive effort went into refactoring 17,000 variables to accomplish this feat, as seen in the refactoring section of these release notes. This will unlock new applications and workflows around EnergyPlus.

Documentation Note

Our build machines have decided to not include the Table of Contents in the InputOutputReference.pdf document on Windows packages. We'll obviously get that fixed, but for now, the full document is posted here in this release along with the installer assets.

EnergyPlus - 9.5.0 IOFreeze

This is the IO freeze version of EnergyPlus 9.5.0. This is intended to give developers time to test out the transitioned objects and structural changes, and give us feedback if something is amiss.

Installer package doesn't grab the input rules file. It is here if you need it: https://github.com/NREL/EnergyPlus/blob/003df71316a25e61ad4499d0903776afaae4bec8/src/Transition/InputRulesFiles/Rules9-4-0-to-9-5-0.md

EnergyPlus - Release Candidate 1 for 9.5.0 IO Freeze

There is still one possible merge tomorrow, but I wanted to get this started. This is a test build that will be deleted without notice, don't rely on it for anything. But if you can pull it once it builds and report your issues/success, that is welcome.

Update: Downloaded the graphical installers and ran on all three platforms. Absolutely no issues running the installers, or running EnergyPlus examples on each machine. I'm going to kick off an EPTravisTester run too, and again, we may have one more PR to go, but if not, then this is ready to re-tag as the official IO Freeze version.

Update 2: I updated EPTravisTester to point to this release, and it passed with flying colors. I still need to test this on a barebones Mac, since that is what caused the last second issue with the 9.4 package, but this is looking really good.

EnergyPlus - EnergyPlus 9.4.0

EnergyPlus 9.4.0

The U.S. Department of Energy (DOE) has released EnergyPlus version 9.4.0. There were many bug fixes and prominent new features this release. The full changelog for this release cycle is listed below. For more information about EnergyPlus, please visit www.energyplus.net.

API Change Notice

EnergyPlus 9.3.0 included a brand new API to enable new workflows around EnergyPlus and also a Python Plugin system where user-defined Python scripts could be called by EnergyPlus during a simulation instead of Erl code written in the input file. While the API is going to be generally quite stable for most releases, there was a major break this release. Most API functions, and the Python Plugin class methods, now accept a state argument. More information is available in the Input Output Reference section on API usage.

Supported Platforms

• Windows 10: 32 and 64-bit versions
• Linux (Ubuntu 18.04 and 20.04) 64 bit versions
• Mac OSX 10.15 64 bit versions (although basic testing shows it seems to work on 10.14)

EnergyPlus - EnergyPlus 9.4.0 IO Freeze

This represents the I/O freeze for EnergyPlus 9.4.0. After this point, no functional changes will be made to the IDD, no structural changes will be made to the output, and no existing API functionality will be broken.

This is not an official release, but instead will allow for interfaces to build upon a stable interface for the upcoming release.

EnergyPlus - EnergyPlus 9.3.0 - Bug Fix Followup Release

This is a bug fix release of EnergyPlus 9.3.0. I am leaving it marked as a pre-release for the time being primarily because the Mac CI instance has gone to sleep, and we cannot get physical access to it right now due to corona, so we likely won't get Mac packages for a few days while we get that reconciled.

This bug fix is not an essential download for most users. The most prominent bug fixes are related to the API/Python Plugin world, where a number of significant fixes went in, alongside extensive unit testing.

Until the Mac download is complete, users are still directed to the original 9.3.0 release. Once the Mac is done, we will do final testing, and then we can mark this as the latest full release.

EnergyPlus - EnergyPlus 9.3.0

EnergyPlus 9.3.0

The U.S. Department of Energy (DOE) has released EnergyPlus version 9.3.0. There were many bug fixes and prominent new features this release. The full changelog for this release cycle is listed below. For more information about EnergyPlus, please visit www.energyplus.net.

MAJOR CHANGES

This version of EnergyPlus contains three new features that are of extreme significance:

• The ability to leverage the GPU for shading calculations, with the potential for major runtime improvement.
• A new Python Plugin/EMS system where the user can write Python scripts instead of using the Erl language.
• An EnergyPlus API that exposes functional, runtime, and data exchange capabilities. An issue was found with linking to the API right before release, that could cause issues on Mac and maybe Windows, which will be addressed in a follow-up bug-fix release of 9.3.0 as soon as possible. Also, API documentation will be generated and posted on the EnergyPlus documentation page and possibly elsewhere soon.

These are brand new features, with new dependencies, and a world of new capabilities. We encourage our users to try these out and report back issues. A more thorough overview is provided in the installed README, and full documentation is found in the InputOutputReference and EngineeringReference documents included with the installers.

Platforms

• Windows 7, 8 & 10: 32 and 64-bit versions
• Linux (Ubuntu 18.04 and compatible) 64 bit versions
• Mac OSX 10.13 64 bit versions

EnergyPlus - IDD Freeze of Version 9.3.0

Looks like we made it to the IO freeze for version 9.3.0. This package contains a lot of new stuff. There are possibly some hiccups as we get all these changes finalized, so please test as much as possible. Some of the new changes include:

• A proper C API exposing functional calculations, runtime callback hooks, and data transfer capabilities
• A Python wrapper around this C API
• A Python EMS system which allows users to define custom control logic and component physics models using Python methods instead of the built-in runtime language.
• Support for using GPU pixel counting to do shading calculations, which has shown significant performance improvements in preliminary testing.
• A Performance "Trade-offs" object which lets the user conveniently adjust some simulation options to make simulations faster, or more enable the full rigorous calculations.

Note that since we are building against Python, we are including the python dynamic library as well as the Python standard library. This is causing the packages to swell up a little this time, but it avoids having to require users to install Python separately.

Note that right now I am not trying to actively support having users install additional packages into the pre-packaged Python standard library. I realize this will be the first thing users ask, and I will be working on formalizing that process later.

Note that we are not linking against Python on Windows 32-bit builds. The CI machine only has 64-bit Python, and so the 32-bit has this disabled. I am unsure whether we will resolve this for release time or not. (32-bit Windows builds are being used less and less.)

Some things that we still are resolving for the official release:

• Documentation of the API and Python Plugins, as well as some packaging tasks (including the header file in the install so users can build against it.)
• Installer cleanups -- hopefully getting QtIFW working robustly on all platforms
• Many bug fixes still to come

EnergyPlus - 9.2.0 Release Candidate 2

This is based on the final-prep-for-92 branch, which only has README related changes. This is the installer that should be broadly tested. If issues are found, we can have an RC3, otherwise, that branch will be merged down and the final 9.2 tag will be based off of develop.

EnergyPlus - EnergyPlus 9.0, Release Candidate 3

OK, this is essentially 9.0. I'm going to let CI make one package build tonight based on the current develop branch. If it is green, I'll re-tag this same SHA with v9.0.0 and we'll be done.

EnergyPlus - EnergyPlus 9.0, Release Candidate 2

It's quick to have RC2 so fast, but I found an issue that will cause RC1 to fail to package. This addresses that and while it is RC2, it is actually effectively the first real release candidate.

EnergyPlus - EnergyPlus 8.9.0; Plus Minor IDD Fixes

I'm not sure what's going to happen with the IDD issues in #6584, but I wanted to leave the door open for a potential quick fix to the release, if that's what we decide to do. I'm keeping this as a pre-release for now. The branch is based on the v8.9.0 (before style) tag, plus a single commit with the plant op schemes added. If it turns out this is our official release, I'll update the changelog here.

EnergyPlus - Styled Version of EnergyPlus 8.9.0

Right after 8.9 was released, we applied a new code style to the whole EnergyPlus codebase. To allow easy diff-ing back to 8.9, I am creating this tag. CI didn't build packages for it because of an issue with parsing the output variable lines of code, but this release isn't intended to be used for packaging or release anyway, just a tag.

EnergyPlus - EnergyPlus 8.5.0

EnergyPlus 8.5.0

Windows packages for EnergyPlus 8.6.0 and prior had a vulnerability in the View3D binary that could expose users to a stack-based buffer overflow. Because of this, all Windows packages 8.6.0 and older have been purged and are no longer available. We apologize for any inconvenience.

The U.S. Department of Energy (DOE) has released EnergyPlus version 8.5.0. The focus of this release was predominantly on bug fixes and code robustness, though some priority new features did get implemented. The full changelog for this release cycle is listed below. For more information about EnergyPlus, please visit www.energyplus.net.

Interface Note

As with every EnergyPlus, older versions of EnergyPlus input files will not run directly with this version, and must be transitioned up to the latest version. EnergyPlus is packaged with transition utilities for updating the idfs automatically. There is also a Rules spreadsheet available in the installation to help interface developers program the transition. We are also tracking the structural changes to the outputs for EnergyPlus and including this documentation in the installer. For 8.5.0, the input rules changes file is here and the output rules changes file is here.

Documentation

The EnergyPlus documentation underwent a full transition from the Markdown/MathJax/HTML basis, to a full LaTeX implementation. This helped drastically streamline the development process and improve the developer's ability to test documentation changes, and also produced much improved pdf documentation over the last couple versions. The conversion was tested several times and confirmed to produce the same content as before to as best as we could tell. However, if you find any structural issues (pieces missing...), please post an issue on GitHub. We are going to be making our way through the entire set of documentation, cleaning up visual issues like alignment or long equations, so no need to post an issue for those visual things. We'll also be styling the documentation up to make it easy on the eyes.

Platforms

• Windows 7 & 8: 32 and 64-bit versions
• Linux (Ubuntu 14.04 and compatible) 64 bit versions; (32-bit and RHEL-compatible versions may be available via Helpdesk)
• Mac OSX 10.9 64 bit versions
• EnergyPlus v8.5.0 has been developed and tested on all of these platforms

Public Release

The U.S. Department of Energy (DOE) has released EnergyPlus version 8.3.0. New feature highlights are listed below. For more information about EnergyPlus, please visit www.energyplus.gov.

Windows packages for EnergyPlus 8.6.0 and prior had a vulnerability in the View3D binary that could expose users to a stack-based buffer overflow. Because of this, all Windows packages 8.6.0 and older have been purged and are no longer available. We apologize for any inconvenience.

Highlights of this release (V8.3.0)

General

• Bug fixes throughout.

Performance

EnergyPlus - v8.2.6

Release

EnergyPlus-8.2.6 is an iteration release, with a focus on performance enhancements. Several parts of the code went through overhauls since the release of 8.2.0 and as a result, the code is now faster than 8.1.0 in all of our test cases.

Numbers

We selected a set of input files that were provided by LBNL from an EnergyPlus performance study several years ago. After transition them from version 2.2 to 8.1, then 8.2.0, then 8.2.6, they were run against each package. The results were great for these files:

• Linux
  • 8.1.0: 1053.5581 [s]
  • 8.2.0: 999.3255 [s]
  • 8.2.6: 857.5618 [s]
• Windows
  • 8.1.0: 1028.5840 [s]
  • 8.2.0: 997.1380 [s]
  • 8.2.6: 876.652 [s]

As you can see, these files didn't show a regression from 8.1.0 to 8.2.0. Yet the enhancements made from 8.2.0 to 8.2.6 still showed a very nice speed improvement.

In addition, our set of regression test files, which is comprised primarily of the example files we package with each release, was run on Windows with full annual simulations. The results are:

• 8.1.0: 5:28:33
• 8.2.0: 6:36:59
• 8.2.6: 4:53:50

As you can see on these, the example file set did show a runtime regression with 8.2.0. This has now been addressed to the point where it is now faster than 8.1.0, by about 35 minutes. There is an improvement from 8.2.0 to 8.2.6 of about 103 minutes.

Enhancements

• Link time optimization utilized during release builds
• Solar-shading and interior radiant exchange performance tuning
• Finite difference wall-conduction model tuning
• Array allocation/dimensioning (heap) tuning

Tuning work is now being done continuously by the development team to ensure that EnergyPlus continues to be a more runtime friendly simulation engine.

Caution

This release package is intended for testing/evaluation only!! Because it is an iteration build, it includes some as-yet undocumented features, including input changes. While the transition program that is packaged with this release will transition your 8.2.0 files up to the latest syntax, you will be left with input files that are a mixed-bag between 8.2.0 and the upcoming 8.3.0 release. This will cause issues later, so please don't use this 8.2.6 build for general deployment.

User Notes

We invite you to try out your input files to check whether they are seeing the same speed increases that we have seen in our testing. Input files differ drastically, and can lead to very different hot spots within the code. Most of the enhancements made recently were because a select file (or set of files) were shown to have regressed in runtime. Once these files were identified, it was generally not too difficult to isolate the hot spot and address it.

If you are seeing a regression still from 8.1.0, we invite you to submit a ticket on the EnergyPlus Helpdesk so we can use this file in our tuning work.

Thanks,

EnergyPlus Development Team

EnergyPlus - EnergyPlus 8.2.0 Update 1

Public Release

The U.S. Department of Energy (DOE) has released EnergyPlus version 8.2.0, the first release of EnergyPlus built on C++ source code. New feature highlights are listed below. For more information about EnergyPlus, please visit www.energyplus.gov.

This is Update 1 of EnergyPlus version 8.2.0 which includes important bug fixes, including a fix for incorrect data in tabular sqlite database outputs. A full list of addressed issues is included with the installer package.

Highlights of this release (V8.2.0)

Core Changes to EnergyPlus

• Internal simulation engine code translated from FORTRAN to C++ to spur the evolution of EnergyPlus through improved interaction with a larger community through a more popular code base, and improved access to code libraries for performance and enhanced capabilities.
• Language change initially caused a slightly slower codebase due to translation overhead, however several restructuring efforts in the code eventually led to EnergyPlus v8.2 being faster than v8.1 in many tests cases.
• Development transitioned to GitHub, where the source code is to be made fully public in the spirit of the open source license.

General

• Bug fixes throughout.

Building Envelope

• Integrated slab calculation now allow improved simulation of ground heat transfer

HVAC, Plant and Refrigeration

• Improved sizing algorithm for including fan heat in cooling coil calculations
• Improved sizing input options for scaling autosized values
• Additional plant load dispatch algorithms based on meeting component part-loading targets
• New models for single-sided natural ventilation with multiple openings
• New on/off fan option for unit heater and unit ventilator
• New fault model for coil fouling
• DOAS direct to zonal water-to-air heat pumps
• Expanded support for table lookup for plant equipment performance
• New zone air mass flow balance option (partially link HVAC flows with zone mixing and infiltration)

Utilities

• Ice storage curve-fit tool

Platforms

• Windows 7 & 8: 64-bit version (32-bit version also available)
• Linux (Ubuntu 14.04 and compatible) 64 bit versions; (32-bit and RHEL-compatible versions may be available via Helpdesk)
