About
HORIS – Home Renovation Integrated Services, a project funded by the European LIFE programme, updated and advanced an existing digital retrofitting platform called Green Menu. HORIS created a digital one-stop-shop (OSS) with the aim of empowering homeowners (of several building types, including flats) during the home renovation process. Homeowners face several key barriers when deciding to retrofit their properties, such as uncertainty and lack of trust about reported energy savings. In addition, they also must choose a home renovation professional and navigate the complexities of the financial process.
The OSS/ Green Menu :
-
- Focuses on helping homeowners make decisions on improving energy efficiency; renewable energy solutions and identify support to reduce energy poverty.
-
- Simplifies the home renovation process – by providing homeowners with relevant and credible information and helping them identify the best and most sustainable options.
By offering financial, legal and technical solutions, HORIS facilitates a smooth customer journey, offering homeowners support on finding renovation professionals and guidance about financial schemes. HORIS matches financing, legal and regulatory, and technical solutions with specific building typologies and homeowners’ needs to streamline action for home renovation, developing standardised contractual arrangements for home renovation.
For whom? The project engages with small and medium sized stakeholders, including local and regional public authorities and non-profit organisations and establishes a network of approved home renovation service providers. Initially, the OSS is set up in Italy, Spain and Portugal with the ambition of replicating in additional countries if needed. Contact us if you are interested!
HORIS focuses on 3 different types of homeowners: Single houses – condominium households – energy-poor households.
HORIS will help overcome 3 main typical barriers blocking home renovation decision:
-
- Administrative, offering the management of work permits and report, assess, manage and process the bonuses and subsidies from which citizens can benefit from.
-
- Technical, advising homeowners on how they can improve their home and have access to lists/rankings/ratings of trusted and validated professionals to ensure a service of the highest quality on a given time.
-
- Financial, helping to find the right solutions available in the market and accompany the consumer in the management of subsidies and tax credits, also giving access to affordable financing.
HORIS, by generating multiple social, environmental, and economic benefits, is a unique opportunity for climate neutrality.
Project Objectives
The overall objective of the HORIS project is to empower homeowners to make informed decisions when renovating. To achieve this aim, a digital One-Stop Shop was developed to simplify the process and guide homeowners to pick the best available services, based on their individual situation.
HORIS :
- Improves energy efficiency in residential buildings and reduce energy poverty by setting up an OSS for Integrated Home Renovation Services, run by consumer organisations.
- Developed a digital OSS that delivers a high-quality user experience and simplifies the home renovation process.
- Encourages international collaboration and innovation by creating a network of home renovation practitioners to help consumers rebuild their homes energy efficiently.
- Provides training to professionals in the implementation of home renovation measures and raise industry standards by highlighting the best practitioners.
- Establishes a sustainable business model that offers renovation service providers incentives to use the OSS to promote their services.
- Builds trust towards the OSS by promoting clear accountability, quality assurance and dedicated consumer protection policies.
- Communicates and disseminates project outcomes.
What will homeowners gain from using the platforms?
On top of quality assurance and guarantees for the entire renovation process to pick the right measures, professionals and financing tools, the platform is available in national languages (Italian, Spanish and Portuguese) and tailored to the market needs. For homeowners, the focus of the value proposition is on comfort, wellbeing, health, social, environmental, and economic benefits.
HORIS connects consumers to network actors, such as construction companies, architects, engineers and financial consultants. HORIS provides:
- Independent and trustworthy information about “what” are the best technical solutions, financing schemes, and legal procedures to mainstream energy renovation for residential homeowners.
- Tailored advice about “how to” renovate depending on products and services available on the market and on the homeowners’ building typology
- Select the “who” will be the right and qualified professional who will do the work, including training the professionals about legislative updates and standards.
- Support to calculate “how much” will it cost and whether there are subsidies to implement the solutions provided within standardized contract types.
- Scale up by typology of homes and target audience thanks to the valuable partners network and beneficiaries of OSS themselves who will become ambassadors.
What will providers gain from being on the platforms?
Professionals will benefit from the trust homeowners put into consumer organisations (the platforms will be hosted by the 3 HORIS consumer organisations) and be offered training for the implementation of home renovation measures. That will allow highlighting the best companies and raising industry standards.
The platform(s)
The One-Stop Shops explained
When it comes to finding information about home renovation (different products, service providers, financial support) consumers are often unsure of where to go and what sources to trust. The idea behind the One-Stop Shop concept is to create an online platform where consumers can get their questions answered. By designing a user-friendly and engaging platform, the OSSs seek to improve consumer confidence in the home renovation market. In May 2025, the ambition becomes a reality and the three HORIS one-stop-shops are now available, hosted by the Italian, Portuguese and Spanish consumer organisations, empowering homeowners to make energy-saving decisions during home renovation.
The launch comes after 18 months of collaborative work by an international consortium of 10 organisations from 4 countries (Italy, The Netherlands, Portugal, Spain) which have partnered to develop these platforms to simplify the home renovation process and help consumers identify the best options for their needs.
The platforms contain each two tools, mapping legal and regulatory aspects for home renovation as well as technical solutions, compiled in optimised packages of measures by country. In the two tools, professionals are validated and their services guaranteed, legal and regulatory aspects for home renovation are mapped and technical solutions for home renovation are compiled in optimised packages of renovation measures by country. You’ll also find “quick wins”, easy and low-cost fixes. HORIS created a network of approved home renovation practitioners to help homeowners make necessary upgrades.
The Green Menu provides technical, legal and financial tips as well as information about sustainable retrofitting measures such as solar panels, heat pumps, insulating glass, green roofs and many more. It presents inspiring example projects and directs users to the Self-scan. Visitors can find information on quick wins, insulation and ventilation, electricity, climatization and water. The Self-Scan is the first step in making buildings more sustainable: direct personalised information about public and private financing schemes available for home renovation and specific energy efficiency and renewable energy solutions in each country, after answering a few questions. Building professionals are listed with a short description, the services they provide and the possibility to get in touch through the Self-scan contact form.
The platforms are available at:
Italy: https://horis.altroconsumo.it – Spain: https://horis.ocu.org – Portugal: www.renovarcasa.pt
These free platforms are built on a model operating for over 10 years in The Netherlands by De Groene Grachten and scaled since then to Portugal, Slovenia and Belgium (Flanders), successfully informing homeowners and activating them to implement sustainable retrofitting measures, with direct benefits for the people living, working and using the buildings. The new tools build on the lessons learned and functionalities of these platforms. They provide homeowners with a simplified approach to renovation, a network of qualified and verified practitioners, and much more!
Technology
In 2019, De Groene Grachten developed an online database containing information about sustainable renovation for historic buildings in the Netherlands. Currently, 55 municipalities and 3 provinces are part of the Green Menu network in the Netherlands. HORIS updated and advanced this existing digital retrofitting platform called Green Menu , designed by Dutch project partner De Groene Grachten and already available in Portugal. An online tool that provides decision-making support for building owners. Designed for various building typologies (homes, heritage buildings, museums, among others), the Self Scan includes specific information about sustainable renovation measures, costs and savings estimations, financing schemes, and local legislation.

With HORIS, we set up a group of sister projects working on OSSs, willing to organise joint events, write briefings, etc. Do not hesitate to write to us if you are interested to join our monthly calls: marine (at) ieecp.org
The #OSS4RenovationCluster: a group of sister projects unite to form a home renovation supergroup to speed up Europe’s Renovation Wave.
The projects, funded by the LIFE and Horizon EU programmes, are joining forces to help support citizens in home renovation. Most are working on innovative solutions such as one-stop-shops to support consumers through each step of the renovation process.
The new generation of OSS (One Stop Shops) projects are key to learn from each other and existing projects, the group meet in monthly calls, to share updates and exchange knowledge in energy-efficient building renovation.
Some of the key challenges they will experience:
– Engaging homeowners
– Getting professionals to register their services on the platform and ensure quality of the services provided
– Developing a sustainable business model after the project ends
– Fostering cooperation between the key stakeholders
