aeclib: Building Code Compliance Library

Open-source automated code compliance building codes and standards.

aeclib translates building code provisions into executable and testable logic.

Installation

pip install aeclib

Intent

The goal of aeclib is to provide a unified "Logic Layer" for the AEC industry to support automated compliance and computational design.

Usage

aeclib is designed as a Stateless Logic Layer. It provides the atomic building blocks of architectural compliance without dictating a specific data schema.

Atomic Logic

Each function in aeclib maps to a specific engineering or code requirement. You are responsible for mapping your own data (JSON, BIM, or Database) to the function's parameters.

Compositional Compliance

The library is designed to be composed into your own application logic. Below is an example of how a user might bring their own JSON design data and map it to a custom Python class to run a specific chapter's compliance check:

{
  "space_id": "RM-101",
  "function_type": "business",
  "gross_area": 1500.0,
  "net_area": 1200.0,
  "design_occupancy_count": 12
}

from aeclib.occupancy import validate_occupant_load_without_fixed_seating, validate_increased_occupant_load

class OccupancyValidator:
    def check_space_occupancy(self, data: dict):
        # 1. Check required minimum occupant load (Section 1004.5)
        is_load_valid = validate_occupant_load_without_fixed_seating(
            function_type=data["function_type"],
            gross_area=data["gross_area"],
            net_area=data["net_area"],
            design_occupancy_count=data["design_occupancy_count"]
        )

        # 2. Check maximum density limit (Section 1004.5.1)
        is_density_valid = validate_increased_occupant_load(
            area=data["gross_area"],
            occupant_count=data["design_occupancy_count"]
        )

        return is_load_valid and is_density_valid

Expected Output

When a design fact fails to comply, the library will return FAIL and log a detailed warning:

WARNING:aeclib:[FAIL] Design occupancy (35) is less than required minimum of 40 for educational_classroom (net area: 800.0, factor: 20).

When a design is compliant, the function returns PASS.
