What Logiciels Perrenoud does

Logiciels Perrenoud (legal name LOGICIELS CLAUDE PERRENOUD) is a privately held French SARL headquartered in Belfort that has developed thermal calculation and building energy simulation software for over 40 years (founded circa 1984 per company communications; firmographic records reference 1969). The company sells a vertically specialized software suite to French building professionals, with flagship products including DPEWin for Energy Performance Certificates (Diagnostic de Performance Énergétique), BatiAudit for energy audits covering incentive-based, regulatory, and Tertiary Decree compliance, BatiSol for underfloor heating calculations, and Ath-CREATOR for RT2012/RE2020 compliance attestations. The portfolio also encompasses modular calculation tools spanning RT2012/RE2020 regulations, RT RENOVATION, heat loss/gain calculations under EN12831, dynamic thermal simulation (STD/SED), network calculations for air/water/gas/sanitation, life cycle assessment (ACV), and BIM digital model linkage.

Underlying technology centers on proprietary thermal calculation algorithms tuned to French building norms, with recent AI integration via Mistral for automated comment drafting in Ath-CREATOR. All products are sold through a direct online boutique with downloadable delivery, multi-seat installation options, and free telephone support; the firm has obtained QUALIOPI certification enabling paid professional training as an adjacent revenue stream. Customers are segmented across bureaux d'études (engineering firms), construction companies (entreprises), HVAC installers (installateurs), building material distributors (négociants), and diagnostiqueurs performing DPE, gas, and electrical diagnostics. Distribution is France-only and supplemented by a co-marketing partnership with BIMEO, which extends reach through BIM platform integration and joint presence at industry events such as ENERJ-MEETING, BIMWORLD, RENODAYS, and RENOV'ACTEUR. The company operates with 1–10 employees, is founder/family-controlled, has raised no external capital, and carries €750,000 in share capital.

Core offering

Logiciels Perrenoud develops and sells thermal calculation and building energy simulation software used by French building industry professionals. The product suite covers regulatory thermal calculations (RE2020, RT2012, RT RENOVATION), Energy Performance Certificates (DPE), energy audits, dynamic thermal simulation, network calculations, and underfloor heating system design. Customers include engineering firms, construction companies, installers, distributors, and diagnosticians who purchase licenses directly through the company's online boutique.

Product overview

Logiciels Perrenoud is a specialized software publisher offering a comprehensive suite of thermal calculation software for building professionals, developed over 40 years. The portfolio centers on three flagship products: DPEWin for Energy Performance Certificates, BatiAudit for energy audits (incentive-based, regulatory, and tertiary decree), and the newly launched BatiSol for heated floor calculations. Additional products include Ath-CREATOR with embedded Mistral AI for RT2012/RE2020 compliance attestations. The offering also encompasses modular calculation tools for RT2012/RE2020 regulations, RT RENOVATION, heat loss/gain calculations (EN12831), network calculations (air, water, gas, sanitation), air conditioning, dynamic thermal simulation, energy consumption balance, diagnostic modules (DPE, gas, electricity), building life cycle assessment, and BIM digital model integration. All software is designed for climate engineering professionals including engineering firms, contractors, installers, distributors, and diagnosticians.

Direct peers

• DesignBuilder Software: UK-based developer of DesignBuilder for dynamic thermal simulation and building energy modeling. Closely comparable product category (STD/SED-style thermal modeling for HVAC engineers and energy consultants) with overlapping engineering audience.
• BBS Slama: French independent software publisher offering thermal calculation and energy audit tools (e.g., Climaudit, Perrenoud-adjacent naming), targeting the same bureaux d'études and diagnostiqueurs in France. Direct head-to-head competitor for RE2020/RT2012 calculations and DPE generation.
• Integrated Environmental Solutions (IES): UK-headquartered provider of the IESVE suite for building performance simulation, including thermal, energy, daylighting, and CFD analysis. Direct peer in dynamic thermal simulation and energy compliance, targeting building services engineers internationally.

Broad incumbents

• Autodesk (Revit / Insight): Global BIM/design incumbent; Revit hosts energy modeling and thermal analysis capabilities that compete with Perrenoud at the high end and increasingly absorb mid-market demand from architectural and MEP firms.
• Nemetschek Group: Parent of Graphisoft (ArchiCAD), Solibri, Allplan and other AEC brands; its design and BIM portfolio embeds thermal/energy capabilities and competes for the same engineering/architecture buyer purchasing Perrenoud modules.
• Trimble (Sefaira / Tekla): Global construction technology provider; Sefaira offers early-stage energy and daylight modeling within Revit/SketchUp, while Tekla covers structural/MEP detailing. Broad incumbent overlap with Perrenoud's energy modeling and MEP calculation scope.

Emerging players

• SimScale: Cloud-native simulation platform offering thermal/CFD and HVAC analysis in browser; not a direct compliance-software peer but increasingly substitutes for traditional desktop thermal calculation tools for performance-driven engineering teams.

Regional players

• CYPE Ingenieros: Spanish developer of building engineering software including CYPETHERM for HVAC load calculations, energy simulation, and code compliance (CTE). Same thermal/energy calculation category as Perrenoud, but oriented to Spanish regulations and Mediterranean markets.
