   • Use fire-rated sealants where required by building codes.
4. Junction Sealing:
   • Address air leakage at junctions between different building components (e.g., wall-roof intersections).
   • Implement air barrier systems to ensure continuous air sealing throughout the building envelope.
5. Vestibules and Airlocks:
   • Install vestibules or revolving doors at main entrances to create air locks and reduce air infiltration.
   • Consider air curtains for service entrances or areas with high traffic.

Cool Roofing Implementing cool roof technologies can significantly reduce cooling loads:

1. Reflective Roofing Materials:
   • Apply highly reflective coatings or membranes to existing roof surfaces.
