AI-Powered HVAC System Designer

Core Logic

The Master Coordinator implements a directed acyclic graph (DAG) execution model that schedules agent tasks based on data dependencies. It monitors agent health, manages retry logic with exponential backoff, aggregates partial results, and ensures graceful degradation when individual agents encounter issues. The coordinator maintains execution state with full observability through distributed tracing.

Core Logic

The Building Analyst processes raw form inputs including dimensions, construction materials, window specifications, and insulation values. It applies validation rules, calculates derived metrics (volume, surface area, U-values), determines climate zone classifications, and structures the data for downstream agents. The agent handles unit conversions and applies regional building code defaults where applicable.

Core Logic

The Climate Optimizer integrates weather data APIs to retrieve historical temperature extremes, humidity levels, solar radiation patterns, and heating/cooling degree days for the project location. It applies climate correction factors to base load calculations, accounts for urban heat island effects, and adjusts recommendations based on projected climate trends for equipment lifecycle planning.

Core Logic

The Load Calculator implements ASHRAE CLTD (Cooling Load Temperature Difference) methodology combined with Manual J residential load calculation standards. It computes envelope transmission loads, infiltration losses, internal gains from occupants/equipment/lighting, solar heat gain through fenestration, and ventilation requirements. The agent produces both peak loads and annual energy consumption estimates with confidence intervals.

Core Logic

The Product Matcher queries the product catalog using calculated load requirements as primary filters, then applies secondary criteria including SEER/EER ratings, COP values, refrigerant types, noise levels, and dimensional constraints. It builds compatible system configurations (outdoor/indoor units, controllers), checks real-time inventory availability, and ranks alternatives by a weighted score combining efficiency, cost, and delivery timeline.

Core Logic

The Cost Optimizer performs Total Cost of Ownership (TCO) analysis incorporating equipment purchase price, installation labor estimates, annual energy consumption at regional utility rates, and projected maintenance costs based on Weibull reliability curves. It models multiple scenarios (basic/recommended/premium tiers), calculates payback periods, and identifies rebate/incentive eligibility for high-efficiency equipment selections.

Core Logic

The Compliance Validator maintains a rule engine with current French RT2020 thermal regulations, EU Energy Performance Certificate (EPC) standards, F-Gas refrigerant restrictions, and local building code requirements. It validates system efficiency ratios, checks refrigerant charge limits, verifies renewable energy integration requirements, and generates compliance documentation including DPE (Diagnostic de Performance Énergétique) pre-certification estimates.

Core Logic

The Report Generator aggregates outputs from all upstream agents and compiles comprehensive proposal documents. It produces executive summaries with key metrics, detailed equipment specifications with product images, installation diagrams, energy consumption projections with environmental impact (CO2 reduction), financial analysis with financing options, and compliance certifications. Reports are rendered in multiple formats (PDF, interactive HTML) with white-label branding support.
