Buildings

• Seal exterior cracks/openings/gaps with caulk, gasketing, weatherstripping, etc.
• Consider new thermal doors, thermal windows, roofing insulation, etc.
• Install windbreaks near exterior doors.
• Replace single-pane glass with insulating glass.
• Consider covering some window and skylight areas with insulated wall panels inside the building.

• Consider tinted glass, reflective glass, coatings, awnings, overhangs, draperies, blinds, and shades for sunlit exterior windows.
• Use landscaping to advantage.
• Add vestibules or revolving doors to primary exterior personnel doors.

conditioned and non-conditioned spaces. Use self-closing doors if possible.
