βœ…Part V: Calculation Logic Implementation

Status: βœ… Complete and Available Implementation Focus: VM0033 emission reduction calculations, Guardian Tools architecture, and comprehensive testing frameworks

This part covers the implementation of calculation logic in Guardian environmental methodologies, with VM0033 as the primary example and AR Tool 14 demonstrating Guardian's Tools architecture.

Part Overview

Part V provides comprehensive guidance on implementing and testing calculation logic for environmental methodologies in Guardian:

Complete implementation of VM0033 emission reduction calculations using Guardian's customLogicBlock, including baseline emissions, project emissions, leakage calculations, and final net emission reductions with real JavaScript production code.

Foundation concepts and architectural framework for parameter relationships and dependencies in environmental methodologies, establishing patterns for future FLD implementation.

Complete guide to building Guardian Tools using AR Tool 14 as practical example, covering the extractDataBlock β†’ customLogicBlock β†’ extractDataBlock mini-policy pattern for standardized calculation tools.

Comprehensive testing framework using Guardian's dry-run mode and customLogicBlock testing interface, with validation against VM0033 test artifacts at every calculation stage.

Key Artifacts and Resources

Prerequisites for Part V

  • Completed Parts I-IV: Foundation through Policy Workflow Implementation

  • Understanding of Guardian's Policy Workflow Engine (PWE)

  • Basic JavaScript programming knowledge

  • Familiarity with environmental methodology calculations

Learning Outcomes

After completing Part V, you will be able to:

βœ… Implement calculation logic using Guardian's customLogicBlock with real production examples βœ… Build Guardian Tools using the extractDataBlock and customLogicBlock pattern βœ… Test and validate calculations using Guardian's dry-run mode and testing interfaces βœ… Debug calculation issues using Guardian's built-in debugging tools βœ… Create production-ready environmental methodology implementations

Next Steps

Part V completes the core implementation knowledge needed for Guardian methodology digitization. Future parts will cover:

  • Part VI: Integration and Testing - End-to-end policy testing and API automation

  • Part VII: Deployment and Maintenance - Production deployment and user management

  • Part VIII: Advanced Topics - External system integration and troubleshooting
