Why Engineering Teams Need Fast Pre-Feasibility

Built for EU Energy Efficiency Directive (EED) Screening & Heat Offtake Negotiations

Under the revised EU Energy Efficiency Directive (EU/2023/1791 Article 26), facilities with a rated energy input above 1 MW must conduct a lifecycle Cost-Benefit Analysis (CBA) evaluating NPV, IRR, and payback for waste heat utilization. Stop rebuilding fragile spreadsheets—run standardized sensitivity checks in seconds.

Engineered for Precision

Complete Thermodynamic & Financial Stack

Every calculation combines First-Law heat pump energy balance with institutional capital budgeting metrics.

🔥

Thermodynamic COP Energy Balance

Automatically derives heat pump compressor shaft power ($P_{\text{elec}} = P_{\text{IT}} / (\text{COP} - 1)$) and total upgraded thermal energy injected into the district heating or industrial loop ($P_{\text{heat}} = P_{\text{IT}} + P_{\text{elec}}$).

Supports Air & Liquid Cooling Profiles
📈

Institutional DCF Valuation (NPV & IRR)

Evaluates Simple Payback, Annual ROI, WACC-discounted Net Present Value (NPV), Internal Rate of Return (IRR), and interactive multi-year cumulative cash flow trajectories.
