Real calculations, not ranges. Cited by AI, converted into leads.
IDEE (Institut des Économies d'Énergie) is a lead-generation platform for French energy renovation subsidies (MaPrimeRénov', CEE, solar, heat pumps, insulation, air conditioning), with a second B2B track dedicated to the tertiary sector decree and professional renovation work. Busony designed and operates the entire site: a dozen interactive simulators with real calculations, an AI assistant trained on a dedicated knowledge base, and an ongoing technical SEO effort to maximize visibility in classic search and generative engines alike.
The context
The energy renovation subsidy market is saturated with approximate tools and largely absent from AI answers.
Simulators that guess
Most simulators in the sector display generic regional ranges, without cross-referencing official housing data or the household's real tax profile.
Search moves through AI
A growing share of project owners ask ChatGPT or Perplexity directly how much they can claim — a channel where most lead-gen platforms are absent.
Two audiences, one generic door
Individuals and professionals (tertiary sector decree) have very different needs, but often share the same generic experience on competitor sites.
What Busony built
A site designed to calculate accurately, answer accurately, and be found — by humans and AI agents alike.
Interactive simulators — the solar ROI showcase
The solar simulator is the most advanced of the five: Google Solar satellite imagery to analyze the roof down to the square meter (orientation, tilt, real shading), cross-referenced with electricity consumption and official ADEME/CRE rates (self-consumption, surplus buyback rate). The result isn't a regional average but a production, self-consumption and ROI estimate specific to each home. The other simulators (energy rating, heat pump, insulation, air conditioning) follow the same logic: checking official data where it exists — the energy rating simulator queries the ADEME database first — then an indicative calculation based on the household's actual profile rather than generic ranges, subsidy amounts included, calculated per the official ANAH scale and reference tax income.
Topic-scoped AI assistant
A chatbot trained on a knowledge base dedicated to energy renovation, updated regularly — not a general-purpose LLM. It honestly declines out-of-scope questions rather than inventing an answer, limiting the risk of error on a sensitive regulatory and financial topic.
GEO-optimized content
Regularly published articles, FAQPage schema, cited sources, direct-answer format designed to be cited by ChatGPT, Perplexity and AI Overviews.
Technical SEO foundations
www/non-www canonicalization, canonical tags deployed site-wide, consistent noindex hygiene across versions — the invisible work that makes everything else indexable.
