The Energy Map project supports EU taxonomy requirements for new constructions and renovations, aiding property managers and housing associations in obtaining loans for energy renovations and helping cities and financiers monitor the energy transition. This is done through a free digital interface that promotes and expedites the energy transition, monitoring carbon neutrality and energy efficiency. Developed with cities like Porvoo and Helsinki, HSY, ARA, and the Finnish Environment Institute, the interface is inclusive, considering underrepresented groups. Service design will be implemented inclusively, considering underrepresented population groups and promoting gender equality, as well as adhering to web content accessibility guidelines and high standards to ensure the open web service is accessible and beneficial to everyone. Project Need Climate change mitigation and energy efficiency improvements are crucial goals nationally and at the EU level. The Uusimaa region has ambitious carbon neutrality targets. The real estate sector, including housing associations, plays a key role. Tools are needed to help property owners enhance energy efficiency and demonstrate emission reductions. Currently, there are no widely used free tools for this. The project aims to fill this gap. Project Objectives The project aims to develop and implement a digital interface that encourages and accelerates the energy transition in properties. Objectives include: 1. Support energy efficiency: Provide accessible information on energy renovations and their impacts. 2. Promote collaboration: Enable cooperation among housing associations in planning and financing. 3. Ensure data security: Facilitate secure information sharing among stakeholders. 4. Meet EU requirements: Support projects in complying with the EU’s sustainable finance taxonomy. 5. Use open-source: Develop with open-source software for wide adoption and continuous development. Development and Implementation User Story: 1. A housing association board uses Energy Map data for EU-compliant renovation recommendations, including economic and climate impact estimates. 2. They log in securely to refine details and receive a detailed plan. 3. Renovations begin with secured financing, inspiring neighbouring associations. The interface is designed with experts and stakeholders and demonstrated jointly. The project stages include: 1. Development: Designing and implementing the open energy model and interface with open-source software. 2. Piloting and Demonstration: Piloting with Uusimaa housing associations, testing, and collecting feedback. 3. Implementation and Training: Wider implementation in Uusimaa and training for effective use. Results and Impact Expected results include: 1. Improved energy efficiency: Practical recommendations lead to better energy efficiency and reduced emissions. 2. Enhanced collaboration: Housing associations collaborate and share information, easing financing. 3. Secure information sharing: Improved renovation planning through secure data sharing. 4. Compliance with EU taxonomy: Easier access to sustainable finance for property owners. 5. Open-source benefits: Widespread adoption and long-term development. Added Value and Long-Term Benefits The interface supports energy efficiency and carbon neutrality in Uusimaa. Long-term benefits include: 1. Cost savings: Long-term savings from improved energy efficiency. 2. Climate change mitigation: Emission reductions meet climate goals. 3. Enhanced user experience: A user-friendly interface improves decision-making quality. Overall, the project advances Uusimaa’s energy transition and serves as a model for other regions and cities in Finland and internationally.
