A guide to StreetBondSR and urban heat island mitigation

Mar 22, 20261 min read

How solar-reflective pavement coatings contribute to LEED credits, reduce surface temperatures by up to 17°C (30°F), and support sustainable urban design in Canadian municipalities and commercial developments.

The urban heat island (UHI) effect costs Canadian cities in cooling energy, public health and pedestrian comfort. Traditional black asphalt, with a solar reflectance index (SRI) near zero, absorbs and re-radiates solar energy, elevating ambient temperatures in urban cores by 2–8°C above surrounding areas.

For landscape architects, urban designers, and LEED project teams, StreetBondSR is an answer they can measure and specify.

How solar-reflective coatings work

StreetBondSR uses UV-stable, solar-reflective pigments that reflect more of the sun's radiation instead of absorbing it into the pavement. Field measurements confirm surface temperature reductions of up to 30°F (17°C) compared to standard black asphalt on plazas, pathways and pedestrian zones.

The water-based, low-VOC formulation goes on existing asphalt and on StreetPrint stamped asphalt.

LEED Credit Pathways

StreetBondSR contributes to multiple LEED v4 credit categories:

  • SS Credit: Heat Island Reduction. Non-roof surfaces with SRI ≥ 29 qualify for performance
  • EA Credit: Optimize Energy Performance. Reduced cooling loads in adjacent buildings
  • SS Credit: Site Assessment. Documented UHI mitigation as part of site sustainability narrative

HUB provides full technical documentation, SRI test data, and specification language for LEED submissions.

Applications in Canadian Urban Design

StreetBondSR has been used on plazas, pathways, and recreational surfaces across Canada where UHI mitigation, pedestrian comfort, and LEED certification are project requirements. Its extensive colour palette, including custom Pantone matching, means a reflective surface can still carry the design's colour.

Specifying StreetBondSR

HUB Surface Systems provides direct technical support for landscape architects and LEED project teams. Contact your regional representative for SRI documentation, specification templates, and colour consultation.
