Validates campaign configuration parameters, dispatches data collection requests, monitors agent progress and dependencies, coordinates parallel execution where possible (parallelization factor 0.65), and synthesizes final recommendations. Maintains comprehensive session metrics including token usage, API calls, cache hit rates, and cost tracking.
Data Collector Agent
Portfolio analysis requires aggregating consumption data, meter readings, and building characteristics from multiple sources across potentially hundreds of properties.
Core Logic
Uses GPT-4 Turbo with temperature 0.1 for reliable data retrieval. Connects to meter data warehouses, queries consumption data for configurable analysis periods, retrieves building characteristics from property databases, and aggregates monthly consumption patterns. Handles 175,200+ records (8,760 hourly readings Γ 20 buildings) with data quality validation.
Data Quality Validator Agent
Analysis quality depends on data completeness and accuracy. Missing readings, outliers, and sensor malfunctions can skew results and lead to incorrect recommendations.
Core Logic
Uses GPT-4o with temperature 0.0 for deterministic validation. Analyzes data completeness across all meters, identifies anomalies and outliers, detects data gaps requiring interpolation, validates readings against expected ranges, and calculates data quality scores (0-100%). Reports confidence levels (HIGH/MEDIUM/LOW) based on quality assessment.
Energy Analyst Agent
Identifying energy efficiency opportunities requires sophisticated pattern recognition, benchmark comparison, and domain expertise across HVAC, lighting, building envelope, and controls systems.
Core Logic
Applies ML models using Claude 3.5 Sonnet with temperature 0.5 for comprehensive analysis. Compares consumption to ENERGY STAR benchmarks, identifies efficiency opportunities across 7 intervention categories (HVAC, lighting, envelope, controls, water, renewable, behavioral), analyzes HVAC performance indicators, and cross-references with ASHRAE 90.1 standards and industry best practices.
Financial Modeler Agent
Investment decisions require rigorous financial analysis including NPV, IRR, payback periods, and sensitivity analysis. Manual calculations are time-consuming and may not consider all variables.
Core Logic
Uses GPT-4 Turbo with temperature 0.0 for precise financial calculations. Computes investment costs using regional pricing data, calculates NPV with configurable discount rates, models cash flows over configurable horizons, performs sensitivity analysis on key variables, and compares Conservative, Balanced, and Aggressive scenarios. Reports IRR, payback periods, and risk-adjusted returns.
Risk Assessor Agent
Energy efficiency projects carry implementation risks including vendor reliability, supply chain issues, technology performance, and regulatory changes. Without risk assessment, projects may fail or underperform.
Core Logic
Evaluates implementation complexity using Claude 3.5 Sonnet with temperature 0.2. Assesses vendor and supply chain risks, calculates confidence intervals for savings estimates, identifies items requiring human review, and generates risk mitigation recommendations. Categorizes risks by probability and impact, flagging high-risk items for stakeholder attention.
Recommendation Engine Agent
Converting analysis findings into actionable, prioritized recommendations requires balancing multiple criteria (ROI, payback, CO2 reduction, tenant comfort, disruption) according to stakeholder preferences.
Core Logic
Uses Claude 3 Opus with temperature 0.7 for creative recommendation generation. Prioritizes opportunities based on configurable weighted criteria, generates implementation roadmaps with dependencies, creates executive summaries with key findings, compiles evidence links for all recommendations, and structures outputs across implementation phases with timeline coordination.
Anomaly Detection Agent
Portfolio-wide anomaly detection requires scanning multiple buildings simultaneously for consumption spikes, potential leaks, equipment failures, and unusual usage patterns.
Core Logic
Scans real-time data streams using Claude 3.5 Sonnet with statistical deviation analysis (3-sigma rule). Detects anomalies across building portfolio, cross-references with historical baselines for validation, identifies potential water leaks requiring investigation, and calculates estimated cost impact. Classifies by severity (low/medium/high/critical) and type (consumption_spike, potential_leak, equipment_failure).
Predictive Maintenance Agent
Reactive maintenance is costly and disruptive. Predicting equipment failures before they occur enables preventive scheduling, reduces downtime, and extends equipment life.
Core Logic
Loads IoT sensor health data and runs ML failure prediction models using GPT-4o with temperature 0.2. Identifies equipment with degradation patterns, calculates remaining useful life (RUL) estimates, generates maintenance schedules with priority ranking, and estimates repair vs. downtime costs. Covers HVAC, boilers, chillers, pumps, motors, meters, and sensors.
Weather Impact Agent
Weather significantly impacts building energy consumption. Without weather normalization, performance comparisons between periods or buildings can be misleading.
Core Logic
Fetches historical weather data using GPT-4 Turbo with temperature 0.1. Calculates heating degree days (HDD) and cooling degree days (CDD), correlates consumption patterns with temperature variations, generates weather-normalized baselines, and determines weather impact percentages on total consumption. Rates building efficiency (excellent/good/average/poor/critical) relative to weather conditions.
Regulatory Compliance Agent
Property portfolios must comply with multiple regulations including HeizKVO, EED, GDPR, ISO 50001, EPBD, DIN, EnEV, and GEG. Non-compliance can result in penalties and operational restrictions.
Core Logic
Uses Claude 3 Opus with temperature 0.0 for precise compliance checking.
