Several OSS implemented in recent years have been analyzed. This analysis covers understanding the type of office—whether in-person, virtual, or hybrid—and the extent of the customer journey they provide, including information, advice, decision-making support, processing, and follow-up. Additionally, it has been noted that the initial intentions and ambitions for the extent of user support and project follow-up were higher than what was actually achieved

The UP-STAIRS Energy Service OSS Framework report presents a detailed design of a "One-Stop-Shop" model to simplify energy efficiency renovations in Europe: stakeholder roles, customer pathways, and financial models to reduce barriers to residential building upgrades. The report also evaluates existing service models to integrate best practices. It provides a framework for local pilot projects to make energy renovation accessible, particularly by offering guidance, coordination, and financial facilitation throughout the renovation process.

The Energy Poverty Advisory Hub (EPAH) Indicators provide essential data for understanding and addressing European energy poverty. This tool includes indicators related to income, energy expenditure, and housing conditions, helping local authorities, policymakers, and stakeholders identify vulnerable populations. By offering insights into the root causes and distribution of energy poverty, EPAH Indicators support targeted interventions and policy development to reduce energy inequality and improve living conditions for those most affected.

The Energy Poverty Observatory (EPOV) provides data, resources, and insights into energy poverty across Europe. It aims to assist policymakers, researchers, and stakeholders in understanding the scope and nature of energy poverty. EPOV includes a collection of data, reports, and case studies—best practices and policies to combat energy poverty and enhance energy access for vulnerable populations.

Introduction on the tool providing solar radiation data, photovoltaic performance analysis, and mapping to support solar energy planning across Europe and beyond.

An extensive resource offering data on building characteristics, energy performance, and renovation activities across Europe to support informed energy efficiency decisions.

Data and tools for evaluating solar radiation and photovoltaic system performance across different regions, supporting the planning and optimization of solar energy projects.
