What is a Glare Assessment?
A Glare Assessment for Building Façades evaluates whether the façade of a new or existing building could cause sunlight reflections that affect neighbouring properties, roads, or infrastructure.
Common scenarios include:
- Modern glass façades or curtain walls;
- Large commercial or office developments;
- High-rise residential buildings; and
- Airports, highways, or transport hubs.
A glare assessment for building façades ensures that reflected sunlight does not cause visual discomfort, hazards, or planning objections.

How buildings can create glare
Reflective surfaces, such as windows, solar panels, or polished cladding, can direct sunlight in ways that affect people, traffic, or surrounding properties. A glint and glare assessment identifies when glare from a building could be an issue, and informs design adjustments to mitigate risks.
When Are Glare Assessments for Building Façades Required?
Glare assessments for building façades are typically requested:
- During planning applications for new commercial, residential, or mixed-use developments;
- When a development includes extensive glazed or reflective surfaces; and
- By authorities concerned with traffic safety, neighbouring properties, or visual amenity.
Early assessment ensures that glare from façade issues are addressed before construction, reducing the risk of planning delays or post-construction complaints.
What Does a Glare Assessment for Building Façades Involve?
Metrica’s glare assessment for building façades include:
Desk Analysis and Modelling
- Assessment of building orientation, façade materials, and reflective surfaces; and
- Identification of sensitive receptors in the vicinity.
Simulation and Evaluation
- Use of 3D models and solar tracking to calculate potential glare zones;
- Analysis of intensity, timing, and duration of reflections; and
- Risk evaluation for pedestrians, drivers, and neighbouring properties.
Mitigation and Reporting
- Recommendations on materials, angles, or shading strategies to ensure adverse impacts are avoided; and
- Clear, planning-ready reporting suitable for submission.
Our approach ensures the visual impact of building reflections is managed effectively.
