Source-guided technical practice

Codes, standards, and technical methods

Start with the jurisdiction and adopted source, then choose the question you need to answer. Guides explain the decision sequence; calculators execute a bounded method; official-source links let you verify the controlling text.

Start with the task

Use a focused hub when one exists, or follow the Code & Compliance workflow for a project review sequence.

Model building code

International Building Code

Occupancy, height and area, fire protection, egress, interior environment, and foundations.

Open IBC hub →Federal accessibility

2010 ADA Standards

Accessible-route and elevator questions kept separate from building-code accessibility checks.

Open ADA hub →Energy and thermal methods

Building energy

Envelope, thermal, energy-use, and certification methods with explicit input and scope boundaries.

Open energy hub →Project workflow

Code & Compliance

Move from applicable authorities and occupancy through calculations, review, and documentation.

Each family keeps its own source and scope. A shared topic such as accessibility, ventilation, or fire safety does not make two standards interchangeable.
