30/11/2019: jEPlus v2.0 Beta is available to download from SourceForge
18/11/2019: About to release jEPlus v2.0. jEPlus+EA v2.0, which is based on the JEA SaaS engine, will follow shortly
17/08/2017: It's been a while since the last update. Well, the good news is that JEA is coming and the new jEPlus+EA will run not only optimisation, but also parametric projects and sensitivity analyses.
07/11/2016: New online tools for EnergyPlus and other simulation users are under development at ENSIMS. They will eventually be integrated into the JESS service. Some of them are useful already on their own, such as the EPW resources map (require access to Google Maps) and the ESO viewer.
21/09/2016: New version of jEPlus v1.7 Beta is available to download. You can now use Python scripts for manipulating EnergyPlus models and input parameters. Also included are Sobol sampling and more probabilistic distribution profiles.
If you receive this error message:
Job xxxxx [REJECTED] - Cannot find any job in job list /data/jess/temp/xxxx/xxxx/jobs.txt when trying to run simulations on the JESS server, it means you need to update jEPlus+EA to v1.7.
31/03/2016: The new jEPlus+EA v1.7.6_beta incorporates many changes to help visualize optimisation results.
20/01/2016: The source code of jEPlus is now hosted on GitHub: https://github.com/jeplus/jEPlus
25/09/2015: Here is a simple example explaining the process of model calibration using jEPlus+EA. Project files are available to download.
08/09/2015: A screencast showing how to use jEPlus with SimLab 2.2 for sensitivity analysis is available on YouTube. If you cannot access YouTube, the video can also be downloaded here: simlab-jeplus_example.mp4
26/06/2015: jEPlus v1.5.2 is a service release to fix a bug on ReadVarsEso extraction. It is available to download from SourceForge.
25/06/2015: JESS now supports run-period split method for accelerating E+ annual simulations. For more information please see the post on LinkedIn
24/02/2015: The latest DesignBuilder V4 Beta package is now shipped with JESS Client 2.0. You can access JESS from DesignBuilder straight after installation. See: download DesignBuilder, JESS Client help
