BPA JUNCTION - LICENCE AGREEMENT
FEG Software Licence Agreement 1.0 with Schedule 1.0 (14/11/2026)

This is the Five Element Group Software Licence Agreement with the Schedule for this product. The Schedule
comes first and sets out what is particular to this product; the agreement follows.

SCHEDULE: BPA JUNCTION
Schedule version 1.0, 14/11/2026, to the Five Element Group Software Licence Agreement version 1.0

Product      BPA Junction, by Building Physics Australia (a business name of Five Element Group Pty Ltd), for Windows
             and macOS.

Price        Free of charge (see clause 4(b) of the agreement). Registration with your email address is required; the
             licence key is emailed to you. A "buy us a coffee" contribution is voluntary and unlocks or changes
             nothing in the Software.

Computers    One licence key per person. Each key is either for one computer, or "roaming": any computers, up to the
             number of computers at a time set on the key, which needs an internet connection while in use. Moving a
             key to another computer is done in the Software (Licence…).

Period       Until it ends under clause 14 of the agreement.

What it does BPA Junction writes thermal bridge reports from THERM 7.8 files and a PHPP workbook you supply, and draws
             and solves two-dimensional heat-flow models with its own solver (the Junction solver). It can also run
             heat-and-moisture studies, import drawings (DXF, PDF, pictures, THERM files), and send models to THERM
             as "THERM packages". It does not change your THERM files. It writes to a PHPP only when you ask it to,
             after making a backup copy.

Validation   The Junction solver has been checked against THERM 7.8 on sample details. Its validation against
             EN ISO 10211 and EN ISO 10077-2 is in progress: until the Software and its documentation say it is
             complete, confirm any result used for Passivhaus certification in a validated tool such as THERM.
             Moisture results (including the mould index) are indicative and depend on the weather, materials and
             assumptions used, which each result states.

Sending      A detail you choose to publish to the public catalogue is sent as an anonymised copy and is not public
             until FEG approves it; by sending it you allow FEG to publish it there. A THERM package you email to
             Building Physics Australia is used only to solve it and send the result back, and is then deleted.

Third-party  THERM (Lawrence Berkeley National Laboratory) and PHPP (Passive House Institute) are not part of the
             Software; you need your own licences to use them.

FIVE ELEMENT GROUP SOFTWARE LICENCE AGREEMENT
Version 1.0, 14/11/2026 (draft, not yet reviewed by a lawyer)

Five Element Group Pty Ltd (ABN 89 627 200 980), Australian Capital Territory ("FEG"), makes software under its own
name and under its business names, including Building Physics Australia. This agreement is the licence for each FEG
software product that comes with it. Each product has a Schedule to this agreement that sets out its price, how many
computers it may be used on, what it does and anything particular to it. Where a Schedule and this agreement differ,
the Schedule applies to that product.

By ticking that you agree, registering, installing or using the Software, you agree to this agreement and the
product's Schedule. If you do not agree, do not install or use the Software. If you accept for an organisation, you
confirm you may bind it, and "you" includes it.

1. Definitions
   "Software" means the FEG product named in the Schedule, in any version FEG supplies to you, with its updates,
   documentation and online services. "Licence key" means the key FEG issues to you for the Software. "Outputs" means
   reports, drawings, files and values you make with the Software.

2. Licence
   FEG grants you a non-exclusive, non-transferable licence to install and use the Software, for personal or business
   use, on the number of computers and for the period the Schedule sets out, while you keep to this agreement.

3. Registration and licence keys
   (a) Some Software needs registering and a licence key. Give accurate details when you register.
   (b) A licence key is for the person (or organisation) it was issued to. Do not share it, publish it or let others
       use it, and do not try to get around the way the Software checks it.
   (c) FEG may suspend or cancel a licence key if you breach this agreement, if the key is shared or misused, if a fee
       is not paid, or where it is reasonably needed to protect the Software, its users or FEG. Where it is reasonable
       to, FEG will tell you why.

4. Price and changes to it
   (a) The price, any trial and any payment terms are as the Schedule sets out.
   (b) Where the Schedule says a product is free of charge, that applies to the versions FEG has supplied to you under
       it. FEG may charge for, or change the terms of, later versions, new features or online services. A change does
       not take away a licence you already hold for a version FEG has supplied, unless it ends under clause 14.

5. What you must not do
   You must not, except as the law expressly allows or the Schedule permits:
   (a) sell, rent, lease, sub-license or charge for the Software itself, or include it in a product or service that is
       sold;
   (b) modify, adapt, translate, reverse engineer, decompile or disassemble the Software;
   (c) remove or change any copyright, trade mark or licence notice; or
   (d) use the Software in breach of any law, or of the licence of any third-party software you use it with.

6. Ownership and your outputs
   (a) The Software is licensed, not sold. FEG keeps all rights, title and intellectual property in it.
   (b) Your Outputs are yours, including for paid work, subject to the rights of others in the information you put
       in.
   (c) If you send FEG suggestions or feedback, FEG may use them without obligation to you.

7. Professional judgement
   The Software is a calculation and reporting aid, not a certification, approval or design service. A competent
   person must check every Output, its inputs and its results before relying on them, including before entering
   values in a planning or energy tool or giving them to a certifier, authority or client. Whether a building or a
   detail meets a standard is decided by the relevant calculation and certifier, not by the Software. What has and
   has not been tested or validated is stated in the Schedule and the documentation, and nothing else in FEG's
   material is a claim of validation.

8. Third-party software and data
   (a) Where the Software works with another product (for example THERM, PHPP, SketchUp or designPH), you need your own
       licence for that product and must keep to it. This agreement gives you no rights in it, and FEG does not make,
       endorse or support it.
   (b) The Software includes open-source components under their own licences, listed in its third-party notices.
       Nothing in this agreement limits your rights under those licences.

9. Your information
   (a) To register and check a licence key FEG keeps your name, email address and organisation (if given), and a code
       made from your computer's hardware identifier (never the identifier itself), with the dates the key was
       issued, activated and checked.
   (b) Joining a mailing list is optional and separate from your licence. You can leave it at any time.
   (c) Anything you choose to send FEG through the Software (for example a detail for a public catalogue or files for
       processing) is handled as the Schedule and the Software say at the time you send it.
   (d) FEG handles personal information under the Privacy Act 1988 (Cth) and its privacy policy
       (buildingphysics.au/privacy).

10. Updates and online services
    The Software may check its licence key and look for updates online. FEG may change, suspend or stop an online
    service. Where the Software works offline, it may still need to go online from time to time to keep a licence
    key active.

11. No warranty
    To the maximum extent permitted by law, the Software is provided "as is", without warranty of any kind, express or
    implied, including any warranty of merchantability, fitness for a particular purpose, accuracy of results or
    non-infringement.

12. Use at your own risk, release and indemnity
    (a) You use the Software and its Outputs at your own risk.
    (b) To the maximum extent permitted by law, you release FEG and its directors, officers, employees and contractors
        from all liability, and waive all claims against them, for any loss, damage, cost or expense of any kind
        arising from or in connection with installing, using, misusing or being unable to use the Software or its
        Outputs, however caused (including by negligence). This includes errors in calculations, designs,
        certifications or construction, and loss of profits or business.
    (c) You indemnify FEG and its directors, officers, employees and contractors against any claim by any other person
        arising from your use of the Software or its Outputs, or your breach of this agreement.

13. Limitation of liability and consumer guarantees
    (a) To the maximum extent permitted by law, FEG is not liable for any loss or damage arising from the use of, or
        inability to use, the Software, including loss of data, profits or business, or any indirect or consequential
        loss. Where FEG's liability cannot be excluded but can be limited, it is limited to the fees you paid FEG for
        the Software in the 12 months before the claim (nil for a free product).
    (b) Nothing in this agreement (including clauses 11 to 13) excludes, restricts or modifies any right or remedy, or
        any guarantee, warranty or other term or condition, implied or imposed by the Australian Consumer Law or any
        other legislation that cannot lawfully be excluded or limited. Where FEG's liability for a breach of such a
        guarantee can be limited, it is limited (at FEG's option) to supplying the Software again or paying the cost
        of having it supplied again.

14. Ending the licence
    (a) You may stop using the Software at any time.
    (b) The licence ends automatically if you breach this agreement, or when its period under the Schedule ends.
    (c) When it ends you must stop using the Software and delete your copies. Clauses 6 to 13 and 16 continue.

15. Changes to this agreement
    FEG may publish a new version of this agreement or of a Schedule. A new version applies to versions of the
    Software supplied, and licence keys issued or renewed, after it is published; FEG will show it before you accept
    it.

16. Governing law
    This agreement is governed by the laws of the Australian Capital Territory, Australia. You and FEG submit to the
    non-exclusive jurisdiction of the courts of the Australian Capital Territory and the courts that hear appeals from
    them.

THERM is software of Lawrence Berkeley National Laboratory. PHPP and designPH are products of the Passive House
Institute. SketchUp is a trade mark of Trimble Inc. FEG's software is not made, endorsed or supported by any of them.
