SaaS energy consumption simulator: savings, CO₂ and real-time action plan.
SaaS simulator that computes household or building energy consumption in real time and proposes a quantified action plan (heating savings, CO₂ reduction, payback period). The tool targets homeowners and energy consultants who need a clear diagnostic to decide on renovations. Modeling is parameterizable by housing type, insulation level, heating mode and climate zone. Results are explained in plain language, not thermal jargon.
Consumer-grade energy simulators give opaque figures or demand endless forms. Professional advisors juggle spreadsheets and expensive specialized software. No middle-ground solution offered both ease of use, transparent calculations and clear, client-ready output.
A Node.js calculation engine based on current thermal regulations, parameterized by climate zone and housing type. Coefficients are externalized in JSON to allow updates without redeployment. The Next.js interface guides the user through short steps (area, insulation, heating, windows) and shows results live: kWh/m²/year, annual cost, potential savings, CO₂ equivalent. An "action plan" prioritizes renovations by ROI.
