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

StreetBondSR and Urban Heat Island Mitigation

Urban Heat Island (UHI) effect costs Canadian cities in cooling energy, public health outcomes, 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 offers a measurable, specification-ready intervention.

How Solar-Reflective Coatings Work

StreetBondSR incorporates advanced UV-stable, solar-reflective pigments that reflect a significantly higher percentage of solar radiation back into the atmosphere rather than absorbing it into the pavement mass. Field measurements confirm surface temperature reductions of up to 30°F (17°C) compared to standard black asphalt — a meaningful shift in the thermal environment of plazas, pathways, and pedestrian zones.

The water-based, low-VOC formulation meets the most stringent provincial environmental regulations and is fully compatible with existing asphalt substrates and StreetPrint stamped installations.

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 deployed in 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 solar reflectance doesn't require sacrificing design intent.
