Natural Light Estimator MCP Connector for Claude

The Challenge of Passive Design

Designing a habitable space requires more than just square footage; it demands sufficient natural light and cross-ventilation. Current building codes (like NBR 15575) mandate specific area ratios for openings, but translating these abstract minimums into physically buildable window dimensions is difficult.

How This System Works

The Natural Light Estimator addresses this gap by providing a structured workflow that connects code requirements to actionable architectural specifications. It uses specialized tools:

1. estimate_light_level: Calculates the theoretical lux level based on input window and room areas, helping assess immediate light impact.
2. normalizeAreaToWindowDimensions: This core tool takes a required minimum area (e.g., 1/6 of floor space) and calculates optimal width and height dimensions that are structurally plausible for US/EU markets.
3. classify_lighting: Provides context by classifying the resulting lux level into categories like 'adequate' or 'dim', helping pinpoint specific areas needing attention.

The Advantage

The system synthesizes these calculations using generateRoomSpecificationReport to produce a single, comprehensive report. This report gives architects and builders not just theoretical minimums, but concrete, dimensioned window specifications that meet code while remaining physically feasible for construction.
