Shadow simulation and sun path planning: essential tools for architects

Architectural design with natural light planning

A sun tracking app like Sun Locator gives architects and construction professionals the ability to predict solar movement with accuracy, turning natural light into a design asset. Through sun path planning, shadow simulation, and AR technology, it’s now possible to create spaces that are both visually stunning and energy efficient.

Why sun path planning matters in architecture

The way a building receives sunlight directly impacts comfort, sustainability, and aesthetics. With sun path planning, architects can:

  • Maximize daylight in living spaces;
  • Reduce the need for artificial lighting;
  • Plan facades and overhangs to control heat in summer;
  • Ensure outdoor areas receive the right balance of light and shade;

By anticipating the sun’s position across seasons, architects can design with precision rather than intuition.

Shadow simulation for architectural project

Shadow simulation for smarter design

Shadows can transform how a structure is perceived and how it functions. With shadow simulation, the architects can visualize exactly how a building will cast shadows at different times of the year. This helps in:

  • Preventing unwanted shading on neighboring properties;
  • Designing public spaces like plazas, gardens, and courtyards;
  • Optimizing solar panel placement for maximum efficiency;

Sun Locator makes these insights accessible from a smartphone, supporting both early-stage design and final client presentations.

AR sun tracker on construction cites

An AR sun tracker bridges the gap between design and reality. On-site, builders and engineers can point their device and instantly see the sun’s trajectory over the actual construction. This helps confirm whether theoretical models match real-world conditions and reduces costly adjustments during later stages.

Sustainable and client-focused design

In an era where sustainability is a priority, being able to demonstrate how a project manages natural light is a powerful advantage. Clients appreciate seeing not just blueprints but also dynamic simulations of sunlight and shadows. A photo planner app like Sun Locator can turn abstract data into an engaging visual story.

AR sun tracker used by architect on-site

Architecture is about shaping spaces and light is one of the most important materials you can work with. By combining sun path planning, shadow simulation, and AR sun tracker technology, Sun Locator empowers architects and builders to design smarter, greener, and more human-centered buildings.
