Roof reflectivity—commonly referred to as “cool roofing”—significantly influences a building’s energy consumption by affecting how much solar heat the roof absorbs In commercial and industrial facilities with large roof areas, choosing roofing materials with high reflectivity can lead to substantial reductions in cooling loads and operational costs.
Procurement and facilities managers benefit from understanding how roofing reflectivity impacts energy efficiency and sustainability.
What is Roofing Reflectivity?
The percentage of solar energy reflected by the roof surface.
Higher reflectivity means less heat absorption, keeping buildings cooler.
Measured as Solar Reflectance Index (SRI), combining reflectivity and thermal emittance.
Energy Impacts of High Reflectivity Roofs
Reduced Cooling Loads: Reflective roofs lower interior temperatures, decreasing HVAC energy use.
Extended Roof Lifespan: Lower temperatures reduce thermal expansion and material degradation.
Urban Heat Island Mitigation: Reflective roofs help cool cities and reduce ambient temperatures.
Materials with High Reflectivity
White or light-colored single-ply membranes (TPO, PVC).
Reflective coatings applied over existing roofs.
Cool metal roofing with reflective finishes.
Elastomeric roof coatings with reflective pigments.
Cost Savings
Energy savings vary by climate but can reach up to 20% on cooling costs in hot climates.
Return on investment through reduced utility bills and longer roof service life.
Considerations
Balance reflectivity with insulation and ventilation.
Maintenance to retain reflectivity, such as cleaning.
Compliance with ENERGY STAR and LEED requirements.
Conclusion
Roofing reflectivity is a powerful lever for reducing energy costs and enhancing sustainability.

Large format tiles—measuring 24 inches or more on one side—have become a popular choice for commercial and high-end residential projects due to their sleek aesthetics and fewer grout lines However, their size presents challenges in achieving precise alignment and flatness during installation.

HVAC systems are essential for comfort but can also be significant sources of noise within buildings, especially in commercial and institutional settings Poorly designed duct systems transmit mechanical sounds and airflow noise into occupied spaces, compromising occupant comfort and productivity.

Large commercial fenestration systems—spanning curtain walls, storefronts, and atriums—play a vital role in building aesthetics and occupant comfort However, expansive glazing can be a major source of heat gain and loss if not properly specified.

High-vibration environments—common in manufacturing plants, transportation hubs, and industrial facilities—pose significant challenges for adhesive performance Standard adhesives may fail prematurely due to continuous stress, leading to bond failure, equipment downtime, and costly repairs.
