Reflective building materials pose risk to birds

Heating and cooling buildings has been identified as a major contributor to emissions from the building sector. To increase insulation and save energy, reflective materials are being applied to building surfaces. These new insulation techniques could pose a risk to birds, as reflective surfaces on buildings have been linked to many bird collision deaths.

Reflective building materials pose risk to birds

Heating and cooling buildings has been identified as a major contributor to emissions from the building sector. To increase insulation and save energy, reflective materials are being applied to building surfaces. These new insulation techniques could pose a risk to birds, as reflective surfaces on buildings have been linked to many bird collision deaths.

A study has shown that bird collisions with buildings are a common and widespread phenomenon in Argentina and that the reflection of windows has a major influence on the number of collisions. This suggests that other reflective materials on buildings, such as reflective insulation material, could also lead to more bird collisions.
