Third-party licences

EnergyFront, PareVia and EPCalibration are proprietary software of ArchOpt Technologies, licensed under the Licence Agreement. They are built with open-source components of other authors. Each component is provided under its own licence, and nothing in the Licence Agreement limits the rights that those licences give you.

1. Notices for each program

Every installer places a file THIRD-PARTY-LICENSES.txt and a LICENSES folder in the program folder. The file is generated automatically for each release from the components that are actually packaged, and lists each one with its version, licence and full licence text. The same files are published here.

Program	Release	Notices
EnergyFront	V3.5	EnergyFront-THIRD-PARTY-LICENSES.txt
PareVia	V3.5	PareVia-THIRD-PARTY-LICENSES.txt
EPCalibration	V3.5	EPCalibration-THIRD-PARTY-LICENSES.txt

2. Qt and Qt for Python (PySide6) under the LGPL

The user interface of the three programs is built with Qt 6 and Qt for Python (PySide6, Shiboken6), Copyright © The Qt Company Ltd. and other contributors, used under the GNU Lesser General Public License version 3. Some programs also contain other LGPL libraries (for example moocore, under LGPL-2.1), named in their notices file.

• These libraries are shipped as separate dynamic libraries in the program folder (Qt6*.dll and the PySide6 and shiboken6 folders) and are loaded at run time.
• You may replace them with modified versions that keep the same interface, and reverse-engineer the program to the extent needed to debug such modifications.
• Their source code is available from code.qt.io and download.qt.io, and on request from architecture.optimization@gmail.com for at least three years after you received the program.

Licence texts: LGPL-3.0 · GPL-3.0 (which LGPL-3.0 builds on) · LGPL-2.1

3. Python and Nuitka

The programs contain the Python runtime, Copyright © Python Software Foundation, under the Python Software Foundation License Version 2. They are compiled with Nuitka; the Nuitka runtime code linked into the programs is covered by the Nuitka Runtime Library Exception, reproduced in each notices file.

4. Not part of the programs

• EnergyPlus is installed separately under its own licence and is not part of the programs. EnergyPlus is a trademark of the US Department of Energy; the programs are not affiliated with, sponsored by or endorsed by the US Department of Energy.
• Your own Python installation, used by the Scripts and Control pages of EnergyFront, and the libraries you install in it are not part of the programs.
• Weather files and other data you use are subject to the terms of their own providers.
