Transforming European Homes: Tech Startups Revolutionize Energy Renovations

Welcome to Europe, where single-glazing, old electric-powered heat emitters, and poor insulation are all too common. Even countries known for their emphasis on household energy efficiency, like Sweden, have room for improvement. This is where startups like Dryft, Enter, BERWOW, and Hubb come in. These innovative companies are leveraging technology to help homeowners assess their home’s efficiency and suggest personalized retrofitting solutions within their budget.

Dryft, a Stockholm-based startup, offers a holistic approach to energy renovations. Instead of simply selling a new heating system, Dryft provides a 30-minute video consultation with an energy adviser to understand the unique features of the property. Based on this consultation, Dryft proposes suitable retrofit solutions and estimates the cost. If the customer decides to proceed, Dryft conducts a thorough survey and carries out the renovation work. With their algorithm constantly refined with real project data, Dryft provides accurate projections of energy savings post-renovation. For instance, a case study showcased a 1970-built house in Stockholm that achieved significant energy savings and improved its Energy Performance Certificate (EPC) rating from G to C.

Enter, an energy retrofit-focused startup in Berlin, offers financing options to help homeowners pay for their renovations in installments. Enter’s app estimates the energy demands of a property and projects the impact of specific retrofit projects on emissions savings, cost reductions, and potential property value increase. This virtual retrofitting tool allows customers to explore different renovation measures and make informed decisions before committing to the actual work. To ensure accuracy, Enter also has a team of experts who conduct on-site surveys and validate app suggestions and projections.

Data plays a crucial role in the energy renovation market. Companies like BERWOW, based in the Republic of Ireland, leverage data analysis to propose suitable renovation interventions based on the Irish Building Energy Rating (BER) certificates. Although accessing standardized energy efficiency data across Europe remains a challenge, BERWOW has developed an automated tool to analyze BER data and provide tailored recommendations. While GDPR regulations initially posed challenges for accessing individual users’ BER certificates, BERWOW has devised alternative ways to access this data, ensuring compliance and user privacy.

Beyond individual homeowners, startups like Hubb are targeting large residential developments and social housing providers. Hubb’s software creates a digital twin of each property and uses machine learning to model energy efficiency improvements. By demonstrating the potential reduction in electricity grid demand through even slight improvements in energy performance, Hubb aims to persuade large companies to prioritize energy renovations on a large scale.

While the cost of extensive energy retrofits can be a deterrent, these startups are also assisting homeowners in accessing government subsidies and grants. They help customers navigate the complex landscape of available funding options and create renovation roadmaps that align with their financial capabilities.

The urgency of the climate crisis, combined with the desire to lower heating costs, calls for widespread energy renovations across Europe. With technology-driven startups leading the way, homeowners and businesses alike have access to tools and expertise that facilitate informed decision-making, personalized retrofit plans, accurate projections, and financial support.

It’s time to think big and fast about energy retrofits, transforming European homes into more sustainable and efficient spaces. With the right support, homeowners can contribute to a greener future while enjoying the benefits of reduced energy expenditure and increased property value.
