## Mission
⅔ of Europe lives where the heat transition has stalled. 52 million homes, most of them dependent on imported oil and gas. We are moving Europe's inner cities out of this dead end and closing the gap that district heating and air-source heat pumps leave open.
## System
Roots is the infrastructure for urban heat. Made in Europe.
The heat system is built from industrially manufactured hydraulic products with end-to-end instrumentation, metering and control. Matched to one another and quality-assured.
## Properties
The range spans urban heat for entire districts down to building groups and single buildings. Classic central heating can be replaced just as readily as decentralised gas boilers, on sound economic and legal footing.

## History
The roots of Roots reach back to 1994. A first heat network started in 2017. Roots was founded to develop scalable system products from it.
**Milestones**
- 1994: Founding of the engineering firm Käferhaus, the technical root of Roots. 30 years of engineering DNA in building services and renewable heat.
- 2017: SmartBlock Geblergasse, the first urban heat network based on renewable energy, by owner and architect Zeininger, goes into operation.
- 2021: Roots is founded. Co-founder Wieland Moser receives the Austrian State Prize 2021 for the technical planning of the SmartBlock Geblergasse.
- 2023: Development of our R&D centre, the Roots·House, begins. Focus on modularisation, standardisation and the acquisition of first first-of-a-kind installations.
- 2024: Research grants (FFG, Vienna Business Agency, Climate Fund) are approved. This enables the capitalisation of the entire system development.
- 2025: We move into the Roots·House. The first installations go into operation. Acquisition of first building-stock owners for broader application succeeds.
- 2026: Series production of the core components from Austrian manufacturing has started. Over 20 further sites in the DACH region are already in implementation.
## Research & Development
We created the Roots·House to bring interdisciplinary product development together under one roof.
**In-House Development**
- Own technology. Own living lab.
- We build the heat system for districts. Hardware, software and logistics under one shared roof.
- The hard work lies in modularisation, standardisation and software development, and in the deep integration of all technical disciplines.
- In the Roots·House in Vienna-Penzing we reproduce every urban scenario under real conditions before a new product goes into production.
- We are funded by FFG, the Vienna Business Agency and the Austrian Climate and Energy Fund.
**Focus Areas**
- Modularisation: We translate complex installation and instrumentation and control technology into prefabricated, modular components. One of our most important results is the Roots·Hub, which replaces entire plant rooms in compact form.
- Standardisation: One of the greatest effects of modularisation is that standards become possible. The focus is on radically simplified interfaces to the remaining project work, reduced to a few steps, and on the foundations for series production.
- Scaling: Building on the modular, standardised components, series production becomes possible. It captures economies of scale, allows higher unit numbers and lowers the marginal cost per component.
**Funding Partners**
- FFG, Austrian Research Promotion Agency
- Vienna Business Agency
- Climate and Energy Fund

> The legally binding version of this privacy policy is the German original. This English text is a convenience translation; in case of discrepancy, the German version prevails.
### 1.1 Controller
**1.1.1** We, Roots Energy GmbH, Linzer Straße 76, 1140 Wien, +43 1 4350730, service@roots.energy, FN 555670 m (Commercial Court of Vienna), GISA number 35818281, VAT ID ATU76906369 (hereinafter referred to as "ROOTS"), are the controller within the meaning of data protection law. ROOTS is the company that decides on the purposes and means of processing personal data within the scope of our range of services and is responsible for security and compliance with the applicable laws. As the controller, ROOTS is subject to numerous information obligations, which are fulfilled by means of this privacy policy.
### 1.2 Scope
**1.2.1** This privacy policy applies to all services provided by ROOTS and the associated use of products and services that ROOTS supplies or makes available. Unless otherwise provided for in this privacy policy, the same definitions apply as in the General Terms and Conditions (GTC). For the purposes of this privacy policy, the clients of ROOTS are also referred to as "users".
### 1.3 Level of Data Protection
**1.3.1** ROOTS regards Austrian and European data protection laws (in particular the EU General Data Protection Regulation, "GDPR") as the minimum standard for handling the data of its clients. These laws are intended to ensure the highest level of data protection worldwide.
**1.3.2** Nevertheless, no one is immune to unlawful access and illegal attacks. To that extent, ROOTS cannot guarantee absolute security of user data. This does not affect the statutory responsibility and liability of ROOTS.
### 1.4 Definitions
**1.4.1** Data protection applies to what is known as "personal data". In short, this means all information relating to an identified person, thereby making that person identifiable.
**1.4.2** The central element of data protection is what is known as the "processing" of personal data. This means any operation involving data, however simple, for example the collection, recording and storage, use, as well as the linking and transmission of personal data, as explained in more detail in the following chapters.
---
### Section: data-privacy-terms/02-data-collection
---
locale: en
order: 2
slug: datenerhebung
title: "Data Collection"
---
### 2.1 Principle
**2.1.1** ROOTS generally collects the data that our clients provide via our website, by email or by telephone in the course of initiating business and the subsequent performance of the contractual relationship. The user thus decides for themselves about the disclosure of their data, although certain minimum details are necessary in order for ROOTS to be able to provide the desired services and products.
### 2.2 Data Collected
**2.2.1** The data entries necessary for the performance of the contract are mandatory and essentially correspond to the master data and contact information of the clients, as well as the data of the property that is the subject of the contract, including the buildings erected on it. These are minimum details that ROOTS requires in order to prepare offers and to ensure the handling of specific orders. In addition, each user may optionally provide further property-related data.
**2.2.2** In the course of initiating business, ROOTS will collect in particular the following data and information:
- First and last name, company name, role/profession, email address, telephone number, address.
- IP address, operating system, browser type and version, and device type. These technical details arise at our hosting provider when it delivers the website and protects it against attacks. ROOTS receives only aggregated statistics from them and does not attribute them to an individual person. No device identifier is assigned.
- Activity events inside the ROOTS tools, for example when a document was corrected or released, and when a document link sent to a client was opened.
- Email and support requests, including the content users send us with them.
- Login data and invoicing data for billing the services commissioned. Means of payment such as credit card or bank account details, and a payment status, are not collected; no payment processing takes place in the ROOTS software.
- Property-related data such as address and land register data. This data is personal data as soon as it can be attributed to an identifiable person. In the initial assessment of a property, that is the normal case.
**2.2.3** Otherwise, data generated during the use of our website may also be collected, for example access logs. ROOTS does not offer sign-in via social networks, and therefore also does not obtain data about users from social networks.
### 2.3 Method of Data Collection
**2.3.1** The manner in which ROOTS collects data arises from the ordering process and the handling of the ORDER:
- Booking an appointment on our website requires information for initiating business, in particular about the property concerned and contact information.
- Communication with ROOTS, in particular via electronic messaging services (e.g. email, messenger, telephone), is used in the course of contract handling. It is primarily the user's decision which information and data are disclosed in active communication with us.
- Performance and billing of the specific order requires contact and invoicing data. Payment itself is handled outside the ROOTS software; means of payment are neither collected nor stored there.
- No cookies for tracking, analysis or advertising purposes are set on our website. No consent is required for this, and none is therefore requested on the website. Beyond that, the user can regulate cookies and similar technologies in the settings of their browser.
### 2.4 Personal Settings and Updates
**2.4.1** Apart from voluntary data entries, there is the option to independently activate or deactivate the collection of certain data in the settings of one's own software.
**2.4.2** In the course of the further development of the range of services offered by ROOTS, the usage options and the associated data collection may be expanded. We will update this privacy policy accordingly.

### Section: data-privacy-terms/03-data-storage
---
locale: en
order: 3
slug: datenspeicherung
title: "Data Storage"
---
### 3.1 Place of Storage
**3.1.1** The data provided by users and collected by ROOTS may be stored on the end devices used. In addition, this data is kept on servers owned or leased by ROOTS. Only cloud systems that comply with the requirements of the GDPR are used.
### 3.2 Duration of Storage
**3.2.1** ROOTS stores personal data at least for the duration of the contractual relationship, that is, for as long and to the extent that the client makes use of services provided by ROOTS and the ORDER has not yet been performed or terminated.
**3.2.2** Project working data and unused documents are erased one year after project completion.
**3.2.3** Used customer originals, extracted content, relevant evidence and the issued result are erased no later than seven years after project completion. Commercial records follow the statutory seven-year period from the end of the relevant calendar year.
**3.2.4** A valid erasure request takes effect earlier. A legal duty or a specific legal claim may delay the erasure of individual data. ROOTS restricts access in that case and erases the data when the reason ends.

title: "Legal Basis"

### 4.1 Principle
**4.1.1** ROOTS uses personal data exclusively for the purposes set out in this privacy policy and on a permissible legal basis in accordance with the GDPR. These may be performance of a contract, legitimate interests of ROOTS, the user's consent, or statutory requirements.
### 4.2 Performance of a Contract
**4.2.1** The main purpose of data processing is the initiation of business, the preparation of offers through to the performance of the specific order, as well as the use of all associated products and services. In this context, ROOTS provides the following services that are inherent to the usage and typical of the contract:
- Collection, verification and management of customer profiles.
- Preparation and transmission of offers.
- Organisation, administration, handling and billing of orders.
- Disclosure of data to suppliers, subcontractors and other cooperation partners.
- Operation and administration of registration processes and online services.
- Provision and administration of messages, notifications and other direct communication, insofar as this forms an integral part of the contractual services.
**4.2.2** Within the scope of the aforementioned purposes, data processing is necessary for the performance of the contract concluded with ROOTS (Art. 6(1)(b) GDPR). If required data (in particular mandatory details) is not provided, business cannot be initiated and a contract with ROOTS cannot be concluded. Data is also collected to process any comments and enquiries that the user may have via various communication channels with ROOTS in connection with the performance of the contract.
**4.2.3** No profiling within the meaning of Art. 4(4) GDPR takes place (Art. 22(1) GDPR).
### 4.3 Legitimate Interests
**4.3.1** The processing of user or client data may also take place around the necessary performance of the contract. In such cases, the data processing is in the overriding interest of ROOTS in order to maintain the functionality and security of our services and to keep operations economically viable. This includes in particular:
- Processing and answering of non-contractual enquiries via email, website contact form, telephone, etc.
- Development, testing and optimisation of required software and business processes.
- Development of technologies and concepts for improving IT security and data protection.
- Prevention of fraud, misuse of services or money laundering, arrangements for reporting suspected misconduct (whistleblowing).
- Carrying out existing-customer advertising, direct advertising and other forms of marketing and advertising.
- Processing for research purposes, including market research, for historical, scientific or statistical purposes.
**4.3.2** The legal basis for data processing in the context of customer support, business development, as well as security and market research is Art. 6(1)(f) GDPR, whereby the legitimate interests of ROOTS lie in the aforementioned purposes and are generally of a security-related, as well as competitive and economic nature.
### 4.4 Legal Obligations
**4.4.1** On the basis of mandatory statutory provisions, judicial or official decisions and orders, or for the purposes of criminal prosecution or on grounds of public or vital interests, ROOTS may be required to disclose or process personal data without the user's consent. In such a case, the user concerned will be informed in good time (insofar as legally permissible).
**4.4.2** This also includes requirements under company law, tax law or commercial law, as well as audit and reporting obligations to which ROOTS as a company is subject. In order to be able to fulfil these, personal data is processed in accordance with Art. 6(1)(c) GDPR to the extent required by the respective law.
### 4.5 Legal Claims and Fraud Prevention
**4.5.1** Finally, the use of personal data may be necessary to prevent fraud or other criminal activity by users, or for our assertion, exercise or defence of legal claims. These are legitimate interests of ROOTS, and therefore in such cases the retention and processing of user data without consent is legally permissible.

order: 5
slug: einwilligung
title: "Consent and Withdrawal"
---
### 5.1 Processing Requiring Consent
**5.1.1** Insofar as the legal bases set out above are not applicable, certain data processing operations require the active consent of users or clients. This includes in particular:
- Ordering and dispatch of a newsletter.
- Analysis and tracking of user behaviour on websites or in apps (cookie policy).
- Transmission of user data to third parties, in certain countries outside the EU.
**5.1.2** The legal basis for data processing within the scope of the aforementioned purposes is the user's consent (Art. 6(1)(a) GDPR), which, where necessary, is obtained at an appropriate point (e.g. in the registration process) or in writing in the course of contract handling.
### 5.2 Withdrawal of Consent
**5.2.1** Consent once given may be deactivated or withdrawn at any time, either in the settings of the browser used or simply by email message to service@roots.energy. The withdrawal of consent does not affect the lawfulness of the data processing carried out up to that point.
### 5.3 Recommendations and Marketing
**5.3.1** Within the scope of the range of services offered by ROOTS, property-related suggestions and recommendations may be made in the future. These may also involve information about products and services from specialised third-party providers, as well as invitations to take part in surveys or other sales-promotion and marketing activities. Any consent required for this is obtained in advance, while at the same time instruction and information obligations are met to the extent required by law.

title: "Data Transfer"
---
### 6.1 Processors and Cooperation Partners
**6.1.1** ROOTS relies on the organisational and technical support of reliable cooperation partners and external service providers (so-called processors) in order to offer comprehensive and optimal use and proper contract handling. The processors are bound by the contracts concluded with ROOTS as well as by the GDPR and process data only in accordance with the specifications and instructions of ROOTS.
**6.1.2** User data is provided in particular in the course of the necessary performance of the contract:
- Suppliers, subcontractors and other cooperation partners provide partial services for ROOTS, where applicable directly to our clients.
- Hosting and cloud services and their tools serve the storage and management of the order data.
- Accounting and payment service providers assist with the billing of the contracts.
- Analytics service providers and their tools help to understand how users use our website, in order to provide tailored communication and product improvements in the future.
- Marketing service providers assist with the creation, sorting, customisation and dispatch of newsletters, advertising and other notifications to users.
### 6.2 Data Transmission within the EU and the EEA
**6.2.1** ROOTS primarily selects cooperation partners that have their registered office or servers within the European Union (EU) or the European Economic Area (EEA). A data transmission within the EU and the EEA is unproblematic, because the GDPR applies in all Member States.
### 6.3 Data Transmission to Third Countries
**6.3.1** In exceptional cases, third-party providers with their registered office or servers outside the EU are engaged. In these cases, a high level of protection in accordance with the GDPR may be ensured with regard to personal data, namely by an adequacy decision of the EU, by which the level of data protection in certain third countries is deemed adequate (e.g. Switzerland, Canada, Japan), and by standard data protection clauses reviewed by the EU that underlie the contractual relationship with processors, or by comparable legal instruments or certifications permissible under the GDPR.
### 6.4 Data Transmission to the USA
**6.4.1** The USA is currently not certified by the Court of Justice of the European Union as having an adequate level of data protection if it does not participate in the Data Privacy Framework Program. In particular, there is the risk that personal data may be subject to access by US authorities for control and surveillance purposes and that EU citizens have no effective legal remedies against this. It is further criticised that access by US authorities is not legally limited to the strictly necessary extent and that no judicial authorisations for this are enshrined in law.
**6.4.2** Before user data is transmitted to US companies that are not subject to the Data Privacy Framework Program, explicit consent is requested at an appropriate point (Art. 6(1)(a) in conjunction with Art. 49(1)(a) GDPR), and the relevant data processing operations are explained (in particular the purposes, data categories and storage period), insofar as this does not already arise from this privacy policy.

title: "Data Subject Rights"
---
### 7.1 Withdrawal and Objection
**7.1.1** Insofar as ROOTS processes data on the basis of consent, every user has the right to withdraw their given consent in whole or in part at any time. In the event of a withdrawal, ROOTS is obliged to erase or irreversibly anonymise the personal data without undue delay (subject to the retention obligations or rights mentioned). A withdrawal does not, however, affect the lawfulness of the data processing carried out on the basis of the consent up to that point.
**7.1.2** Every user also has the right to object to data processing based on legitimate interests of ROOTS, if grounds for this arise from their particular situation. Where personal data is processed for the purposes of direct advertising (including profiling), the user may object to this.
### 7.2 Information, Rectification and Restriction
**7.2.1** Every user has the right to request information about the processing of their personal data. The right of access includes information about the purposes of processing, the categories of data and recipients, the storage period, any origin of the data, as well as the rights under data protection law. All of this can in any case already be found in this privacy policy and can be made available on request in an electronic format.
**7.2.2** Should it turn out that individual items of personal data are incorrect, the user may at any time request the rectification or completion of their data. For the duration of any examination of a request, there is also the right to restriction of data processing.
### 7.3 Erasure ("Right to be Forgotten")
**7.3.1** Every user has the right to request the erasure of their personal data. If the data is no longer necessary for the performance of the contract, a declaration of consent is withdrawn or an objection is made to data processing, then the data is erased without undue delay.
**7.3.2** If delays arise due to identity verification or for technical or economic reasons, the data processing is restricted as far as possible until final erasure. Apart from this, it should be noted that further data processing may still be necessary, namely for the fulfilment of legal obligations (including post-contractual handling), on grounds of public interest, or for the assertion, exercise or defence of legal claims.
### 7.4 Data Portability
**7.4.1** Every user has the right to request that an overview of their personal data be transmitted to another controller, insofar as this is technically feasible (right to data portability).
### 7.5 Right to Lodge a Complaint
**7.5.1** Should a user be of the opinion that ROOTS does not adequately safeguard data protection rights, they may contact us at any time by message to service@roots.energy.
**7.5.2** Otherwise, every user has the right to lodge a complaint with the competent Austrian Data Protection Authority (www.dsb.gv.at) at 1030 Wien, Barichgasse 40-42, if they consider that the processing of their personal data infringes data protection law. In addition, the right to lodge a complaint may also be exercised before a supervisory authority in the EU Member State of the place of residence, the place of work or the place of an alleged infringement.

### 1.1 Definitions
**1.1.1** We, Roots Energy GmbH, Linzer Straße 76, 1140 Wien, +43 1 4350730, service@roots.energy, FN 555670 m (Commercial Court of Vienna), GISA number 35818281, UID ATU76906369 (hereinafter referred to as "ROOTS"), are consulting engineers and support property owners, owners' associations, property managers, commercial property owners, developers, planners, architects and other project participants in converting the heating and cooling supply of buildings and projects to renewable energy sources or to district heating, or in planning it accordingly anew.
**1.1.2** Under the motto "Out with oil and gas", ROOTS offers services in the field of decarbonisation, heating and cooling supply, and technical systems planning. These include in particular feasibility studies, design and other planning services, consulting services, service and operational optimisation services, as well as, in each case in accordance with the OFFER, the supply, integration and provision of modules, system components, digital services and other products. These services may relate to existing buildings, the conversion of existing installations, and new-build and other new projects.
**1.1.3** Our offering is directed at private house or apartment owners, at owners' associations or their property managers, as well as at institutional market participants such as developers and commercial property owners, and furthermore at planners, architects and other project participants. Any person who orders services or supplies from ROOTS is hereinafter referred to as the "Client" (hereinafter referred to as "CL"). Where designations relating to natural persons are stated in these Terms only in the feminine or only in the masculine form, they refer to all natural and legal persons irrespective of gender.
### 1.2 Brief Description
**1.2.1** The Client may, via the website, by email or via other communication channels notified by ROOTS, request a non-binding offer for services or supplies by ROOTS for a specific property or a specific project (the "OFFER"). For this purpose, the provision of contact data for processing the OFFER as well as those object, project or usage data that are required for preparing the offer and rendering the service is necessary.
**1.2.2** On the basis of the information provided, ROOTS prepares the OFFER for the specific property or the specific project, which is transmitted to the CL by email or made available for download. Upon acceptance by the CL, the contract for the chargeable services and/or supplies designated in the OFFER comes into existence between ROOTS and the CL (the "ORDER").
**1.2.3** In order to perform the ORDER, ROOTS requires from the CL further parameters and documents relevant to the respective service or supply (e.g. existing plans, energy performance certificate, technical documents, project documents, connection data or other information) and may, where applicable, carry out a site inspection. Insofar as ROOTS provides digital services, these may serve communication, data provision, monitoring, control, documentation, and service or operational optimisation.
**1.2.4** Payment of the fee or purchase price is made in accordance with the agreement in the OFFER. The scope, type, time of performance, any delivery dates as well as any digital or ongoing service performances result primarily from the respective OFFER. Commissioning, assembly, installation, dismantling, disposal or the laying of pipework is owed only where this is expressly agreed in the OFFER.
### 1.3 Applicability of our Terms
**1.3.1** These General Terms and Conditions, in their respective applicable version (the "Terms"), apply to all offers, orders and services between ROOTS on the one hand and the Client on the other, and that worldwide.
**1.3.2** By accepting the OFFER, the CL declares its full and complete agreement with these Terms. Without consent to our Terms, further processing by ROOTS is not possible. Every OFFER, every subsequent ORDER as well as the use of any digital services of ROOTS are subject exclusively to these Terms.
**1.3.3** Upon requesting an OFFER or at the latest upon its acceptance, the CL confirms (i) its acknowledgement and unreserved acceptance of the content of these Terms, (ii) that it has legal capacity under applicable law and is entitled to conclude contracts, as well as (iii) that all information is true, correct, current and complete. We reserve the right to contact Clients in order to verify registration data, project details and usage information.
**1.3.4** ROOTS expressly objects to any conflicting terms and conditions or other terms of use of Clients, their agents or third parties. Differing, conflicting or supplementary terms therefore do not become part of the contract unless we expressly agree to them in writing.
**1.3.5** Should we cooperate with various partners in connection with the provision of our services, we will draw attention to any applicable terms and conditions of a third-party provider.
**1.3.6** We expressly reserve the right to make future adjustments and amendments to our Terms. Adjustments may, for example, be necessary in order to meet legal or technical requirements. Amendments are possible at any time and we will announce them in an appropriate manner before they take effect, whereby an objection may be made in writing within one month of the announcement. If no objection is made, the continued use of our offerings is subject to the respective new Terms.
