Afrexai Energy Audit

# Energy Audit — Commercial Building Assessment

Run a full energy audit for commercial or industrial facilities. Identifies waste, models savings, and generates a prioritized retrofit roadmap with ROI timelines.

## What It Does

- Collects utility data (electric, gas, water, steam) across 12+ months
- Benchmarks consumption against ASHRAE and ENERGY STAR baselines
- Identifies the top 10 energy conservation measures (ECMs) ranked by payback period
- Calculates simple payback, IRR, and lifecycle cost for each measure
- Generates an ASHRAE Level II audit report with executive summary
- Flags utility rate optimization opportunities (demand response, TOU shifting)
- Maps available rebates and incentive programs by state/region

## How to Use

Tell your agent:
- "Run an energy audit for our 45,000 sq ft office building"
- "Analyze our utility bills and find savings opportunities"
- "Create a retrofit roadmap for our warehouse — budget is $200K"

Provide:
1. **Building type** — office, retail, warehouse, manufacturing, healthcare, education
2. **Square footage** and location (climate zone matters)
3. **12 months of utility bills** (or monthly kWh/therms if summarized)
4. **Operating hours** — shifts, weekend usage, seasonal patterns
5. **Major equipment** — HVAC age/type, lighting, compressed air, process loads

## Audit Framework

### Benchmarking
- EUI (Energy Use Intensity) = total kBtu ÷ sq ft
- Compare against CBECS median by building type
- ENERGY STAR score target: 75+ (top quartile)

### Energy Conservation Measures (ECMs)

| Category | Typical Savings | Payback |
|----------|----------------|---------|
| LED retrofit | 40-60% lighting | 1-3 years |
| HVAC controls/BMS | 15-25% HVAC | 2-4 years |
| VFDs on motors/fans | 20-50% motor | 1-3 years |
| Envelope (insulation, air sealing) | 10-20% heating/cooling | 3-7 years |
| Demand response enrollment | 5-15% peak demand | Immediate |
| Solar PV | 30-70% electric | 5-8 years (with ITC) |
| Heat recovery | 10-30% t...
