【Sunlight Calculator - Home Sun Exposure Analysis Tool】
Sunlight Calculator is a professional home sun exposure analysis tool that helps you objectively evaluate lighting conditions when choosing a property. Through 3D modeling and solar trajectory simulation, it provides visualized sunlight data for your reference.
Core Features
【Multiple Modeling Methods】
Floor Plan Modeling: Import residential community floor plans to quickly build a 3D model
Map Modeling: Select the community location on a map to automatically obtain geographic coordinates
Building Spacing Modeling: Enter building spacing and height parameters to simulate shading conditions
Unit Layout Simulation: Simulate sunlight distribution and shadow changes at different times of day on the floor plan
Model Editing: Adjust floor height, building orientation, and other parameters
Save & Share: Models can be saved locally or shared with family and friends
【Professional Sun Exposure Analysis】
Solar Trajectory Simulation: Display the sun's path at any date and time throughout the year
Sunlight Duration Statistics: Calculate cumulative daily sunlight hours at each location
Time-Period Analysis: View lighting conditions in the morning, afternoon, and throughout the full day
Winter/Summer Comparison: Compare lighting differences on key dates such as the winter and summer solstices
Sampling Point Analysis: Select specific locations to view detailed sunlight data
Dynamic Playback: Play full-day sunlight change animations to intuitively understand lighting patterns
【3D Heatmap Display】
Color Grading: Red–orange–yellow–green–blue gradient representing lighting from excellent to poor
Layer-by-Layer Display: View sunlight distribution for each floor individually
Multi-Building Comparison: Display heatmaps for multiple buildings simultaneously for easy side-by-side comparison
Precision Settings: Adjust calculation precision to balance speed and accuracy
Data Labeling: Display sunlight duration values directly on the 3D model
【Window View Simulation】
Perspective Switching: Simulate the field of view looking outward from different floors
Obstruction Analysis: Show the degree to which buildings ahead obstruct the view
Landscape Assessment: Determine whether greenery, water features, and other scenic resources are visible
Floor Comparison: Compare view differences across different floors
Distance Measurement: Calculate the actual distance from a window to the building ahead
Height Annotation: Display the relationship between line-of-sight height and the height of obstructing structures
【Report Generation & Export】
Single-Floor Report: Generate a detailed sun exposure analysis report for an individual floor
Batch Reports: Generate comparison reports for multiple buildings or floors with a single tap
Multiple Formats: Supports export as PDF, PNG image, or CSV data spreadsheet
Custom Templates: Choose from different report styles and content modules
Print Optimization: PDFs are automatically paginated to fit standard A4 paper
Usage Tips
【Data Accuracy】
Calculation results are based on theoretical models; actual sunlight is subject to weather conditions
Entering accurate building parameters is recommended to improve simulation precision
The model does not account for temporary obstructions such as trees or billboards
Results are for reference only and should not be used as the basis for legal or commercial decisions
【Best Practices】
Recommended to combine tool analysis with in-person visits, observing actual lighting at different times of day
Take on-site photos to compare and verify against simulation results
Pay special attention to winter lighting — sunlight hours are shortest on the winter solstice
