Solar Reflectivity Studies

Quantifying buildings’ interaction with the sun to ensure safety, efficiency and comfort

Some recent high-profile skyscraper designs that employ extensive exterior glass paneling have generated solar reflectivity, causing negative outcomes, such as melting plastic car parts and creating hazardous glare to neighboring buildings and nearby traffic. Solar reflectivity can also raise surface temperatures on adjacent properties and kill vegetation. Building energy modeling can be invalidated if light reflected from neighbor­ing buildings is not taken into account.

With Solar Reflectivity Studies we can help the design team:

  • Determine whether reflected glare will present problems for motorists, pedestrians and adjacent buildings.
  • Identify the path of solar reflections, shadowing and glare intensity.
  • Develop glare mitigation strategies that are sensitive to overall design goals and reduce negative impacts on adjacent buildings, vegetation, motorists and pedestrians.

NEAPOLI performs detailed engineering analysis via Computational Fluid Dynamics (CFD) to address the angle and intensity of reflected sunlight from a building’s facade. NEAPOLI can predict not only the location of reflected light, but also the intensity of  these reflections and the related temperature increase originated by the reflected light.

With this deep understanding of how a design will interact with the sun, the design team can quickly and accurately quantify impacts and assess the need for and effectiveness of mitigation measures.
