Comparative Assessment of Smart Ready Technologies Using Economic and Technological Metrics

Abstract The implementation of Smart Readiness Technologies (SRTs) across the European Union remains uneven, hindered not only by technical and regulatory variability but also by a lack of standardized financial viability metrics. This study introduces a dual-indicator framework combining the Risk-Adjusted Discount Rate (RADR) and the Return on Smart Investment (RoSI) to assess the financial feasibility of SRT deployment. RADR integrates country-specific risk premiums using macroeconomic inputs such as sovereign bond yields, energy price volatility (Eurostat), and green finance accessibility (EU Green Bond data). RoSI captures net financial performance over a 10-year device lifecycle, incorporating installation, operation, and maintenance costs against projected energy savings. The analysis applies this framework to six EU countries—Austria, Greece, Cyprus, Spain, Italy, and the Netherlands—revealing a clear relationship between national market risk and the investment viability of smart technologies. Devices such as the RVL482 Heating Controller maintain strong RoSI under both standard and risk-adjusted conditions, while others (e.g., ultrasonic heat meters) consistently underperform. High RADR values in Greece and Cyprus correspond to larger RoSI reductions, suggesting potential barriers to private-sector uptake. Conversely, countries with mature green finance ecosystems and stable energy markets exhibit greater technology viability even without subsidies. These findings reinforce the importance of integrating financial readiness indicators into Smart Readiness Indicator (SRI) frameworks to inform incentive design, investment prioritization, and policy planning.
