The Problem & Requirements

Residential and commercial building managers needed a tool to compute thermal loads and energy consumption based on room dimensions, sunlight exposure, and occupancy to make cost-effective hardware purchases.

My Personal Contributions & Responsibilities

✓Implemented Bloc state management to process multi-variable mathematical formulas in real-time.
✓Designed dynamic form wizards using go_router to capture room dimensions, window orientations, and insulation metrics.
✓Built interactive recommendation cards displaying projected kilowatt-hour savings and return on investment (ROI).
✓Delivered clean, responsive mobile layouts adhering to Material Design principles.

Technical Challenges & Problem Solving

Challenge #1•

Ensuring instant calculation updates without freezing the main UI thread during complex thermal capacity calculations.

Architectural Solution:Offloaded heavier math iterations to Dart compute isolates or pure domain utility classes, emitting calculation states cleanly via BLoC events.

Architecture & System Design

Architecture BlueprintBloc State-Driven Clean Architecture

Events triggered by user dimension changes yield state mutations containing calculated energy efficiency ratings.

Data & Control Flow:

Dimension Input Forms -> Bloc Events -> Calculation Engine -> Energy Recommendation State

Features Implemented

•Room dimension & environmental parameter input wizard

•Instant BTU and tonnage recommendation engine for air conditioning

•LED vs traditional lighting consumption cost comparison graphs

•Exportable energy audit summary reports

Conceptual Energy Calculator Layout

[1] Input & Event Stream

User gestures & socket events handled with debounced controllers.

[2] State Transformation

Computed by Bloc without touching database models directly.

[3] Reactive Projection

Widgets rebuild conditionally via target selectors for optimal frame rates.
