The ReLIFE Platform - ReLIFE-Project-EU/relife-wiki GitHub Wiki
The ReLIFE Platform is the web-based user interface that brings the ReLIFE Tools together in a single application and connects them to the underlying Services.
The architecture follows a layered model:
- Services are the foundational building blocks. They handle the heavy computation: energy simulation, financial modelling, and multi-criteria decision analysis.
- Tools are the user-facing features built by composing those Services. Each Tool targets a specific audience and combines the Services in a way that fits that audience's needs.
- Platform is the web-based UI layer that hosts the Tools and gives users a coherent, integrated experience.
Note
The platform is currently in active development. Core functionality is operational, while some features continue to evolve.

High-level view of the ReLIFE Platform, the three user-facing Tools, and the shared Services that support them.
The platform exposes three Tools for distinct user groups:
| Tool | Audience | Focus |
|---|---|---|
| Home Renovation Assistant (HRA) | Homeowners, tenants, small building owners | Single-building renovation with simplified guidance |
| Portfolio Renovation Advisor (PRA) | Financial institutions, ESCOs, large-scale owners | Portfolio-level assessment with detailed financial analysis |
| Renovation Strategy Explorer (RSE) | Policymakers, urban planners, researchers | National/regional building stock analysis and strategy development |
Current implementation status in the web UI:
| Tool | Current availability |
|---|---|
| HRA | Live guided workflow |
| PRA | Live guided workflow |
| RSE | Landing page only, with "Coming Soon" messaging |
See the individual tool pages for detailed workflows, inputs, outputs, and current limitations.
Three backend Services provide the building blocks used by the Tools:

A["User Input"] --> B["Forecasting Service"]
B --> C["Financial Service"]
B --> D["Technical Service"]
C --> E["Ranked Scenarios &<br/>Recommendations"]
D --> E
- Forecasting Service simulates building energy performance under present, 2030, and 2050 climate scenarios.
- Financial Service evaluates renovation economics: financial indicators, funding options, and risk assessment.
- Technical Service provides renovation measure specifications and ranks scenarios through Multi-Criteria Decision Analysis (MCDA).
The current web UI does not use all three Services in the same way for every Tool:
- HRA currently uses the Forecasting, Financial, and Technical Services in its active flow.
- PRA currently uses the Forecasting and Financial Services in its active flow. Technical-service-backed ranking is planned but not active yet.
- RSE does not yet run an analysis workflow in the current platform instance.
