Terms and Conditions

We, KPPK Ziviltechniker GmbH, Gumpendorferstraße 139/1/9, 1060 Vienna,, ("KPPK", "we", "us"), are pleased that you want to use the beta version of our software solution for calculating the amortization time of investments in alternative energy sources R.O.S.E.® "Reckoning of Sustainable Energysystems" ("Software"). By registering and using the Software, you accept the following Terms and Conditions ("T&C").

The use of the free of charge Software provided by KPPK is exclusively permitted on the basis of the present T&C. The Software is currently in the testing and development stage. The present T&C may therefore be amended, modified or replaced at any time to reflect further developments. In this case, you will be notified of any changes when you open the Software. The amended T&C will apply to the subsequent use.

Only persons over 18 years are entitled to use the Software and only for professional purposes. The offer is therefore not aimed at consumers.
In order to use the Software, registration on the website is required. Our Software is based on the Progressive Web App (PWA) architecture, which utilizes modern browser features and allows offline use. No installation on the respective end device is required. Due to the encrypted PWA architecture, all calculations are carried out in your browser.

Our Software includes the following functions:
• Comparison of investments in alternative (e.g. solar energy, air or geothermal energy) and thermal energy sources (e.g. natural gas); comparison of amortization time over several decades using the cash value method;
• Overview of current government subsidies, projected energy price and interest rate developments;
• Representation of CO2 savings on a percentage basis and with future effect.
The comparison depends on the data of the respective project such as energy performance certificate, heating load or building data (gross floor area, building class, building type etc) and data on existing energy systems (base costs, annual changes, CO2-equivalent). Based on these inputs, the Software uses predefined parameters to calculate non-binding potential savings when switching to alternative energy sources. The calculated parameters are based exclusively on our internal cost structure for corresponding new construction- or refurbishment projects.
All results are only approximate values, which, according to the manufacturers, can be achieved under ideal conditions if you implement your project with us. Actual savings may be lower than shown in the calculation, in particular due to the exhaustion of government subsidies or other restrictions. The comparison result of the Software is therefore for information purposes only and does not represent a binding commitment of actual cost savings or a concrete cost estimate. The extent of concrete savings potential can always only be determined in the context of an actual project offer through us.

Users undertake to comply with the T&C and to provide correct and valid data during the registration process. Users are responsible for any necessary software, hardware and internet connection.
The results are for individual use only. Misuse of the Software is not permitted. In particular, data entered by users must not be capable of causing damage to the Software, our servers or other technical equipment of KPPK.
Users are prohibited from decompiling, disassembling, reverse engineering, copying, transferring or otherwise exploiting the Software or any of its contents, except as permitted by copyright law.
You may delete your account or request deletion from us at any time. In that case, you will no longer be able to use the Software. We also reserve the right to refuse the registration of a user without giving reasons or to delete the existing registration.

Except for the information provided by the users, all elements of the Software, in particular the design, structure, development logic and content of the linked database are protected by copyright and further intellectual property rights. Without our explicit consent, the user does not acquire the right to reproduce, distribute, rent or lend, make available to the public, broadcast, perform and present, display, edit, translate or otherwise exploit the Software or individual elements thereof.

We provide the Software with due care. All calculation methods are based on the state of the art. The calculation methods and comparative energy prices are updated regularly - at least once a year - in order to keep the Software up-to-date.
However, it is not possible to completely avoid errors, possible violations by third parties or malfunctions in the Software. Therefore, particularly against the background that the Software is provided free of charge and its beta status, we do not assume any warranty - also taking into account the risks of the Internet - for the correctness, reliability, quality, suitability, completeness and availability of our Software or the results obtained. Accordingly, content of the Software may be out of date, incomplete or inaccurate. We will make every effort to correct any errors found or reported.
The respective comparison results depend on the information provided by the user and are only estimates under ideal conditions. Actual savings may differ from those calculated by the Software due to the large amount of external influencing factors. We do not assume any liability for the correctness, reliability, availability and accuracy of the content. In particular, we are not liable for the correctness and completeness of the displayed information and savings potential.
Liability is excluded in view of the free provision of the beta version. The limitation of liability does not apply to intentional damage.

User shall fully indemnify and hold us harmless to full extent and free of any claims, damages, liabilities, costs, losses and expenses arising out of (i) User's willful or negligent breach of these T&C and (ii) User's negligent infringement of any third party rights, including but not limited to intellectual property, privacy or data protection rights.

The T&C are subject to Austrian law, excluding the UN Convention on Contracts for the International Sale of Goods.
The competent court for all disputes, including the question of the lawful conclusion of this Agreement, shall be exclusively the competent court for the first district of Vienna, Austria.
