Exterior low-e storm windows were added to historic Halligan Hall on the U.S. Naval Academy campus in Annapolis, Maryland; frames were custom colored to match the existing seafoam green window trim
Image
Extreme weather, such as wind, fire, flood, or extreme heat (included in the Severe Weather category above) causes most large electric disturbance events in the U.S (defined as affecting at least 50,000 customers) (data from 2000-2016)
Image
Image
Ice dams form when warmth from the attic causes roof snow to melt and flow to roof eaves where it refreezes at the colder overhang and forms a buildup of ice causing more snowmelt to puddle where it can wick back through shingles and leak into the attic
Image
Ice dams formed by melting of snow on roofs can affect roofs, walls, ceilings, siding, and insulation.
Image
Installation of permanent exterior low-E storm windows is simple and easy, requiring a few basic tools and about 20 minutes of labor
Image
Interior storm windows have very little impact on the appearance of the window, although the window frame may appear slightly wider

Image
Modern interior storm windows include new technology and sleek design features that offer an easy-to-install, cost-effective method for upgrading the energy efficiency of existing windows
Image
Modern Low-E storm windows are typically kept up year-round but can be removed without damage to the existing window frame, an important consideration for historic preservation projects
Image
Modern low-E storm windows can significantly improve the energy performance of the home by reducing both air infiltration and thermal conductance through the window assemblies
Image
Image
Right - A dimpled-plastic geotextile mat covers the below-grade insulated concrete form (ICF) foundation to help keep water out of the foundation and to reduce hydrostatic pressure on the foundation during freeze-thaw cycles in winter.
Image
Right - The high-efficiency wood stove is located on an interior wall in this home to provide a secondary heating source in cold climates.

Image
The goal of foundation moisture management is to construct the basement, crawlspace, or slab in a way that keeps moisture from getting in in the first place
Image
The icicles and the bare spot along the left roof ridge indicate that heat from the second-story room may be heating the underside of the roof deck, melting the snow and likely leading to ice dam formation.
Image
Image
The polyethylene ceiling vapor barrier is sealed to form an air barrier around the exhaust fan in this very cold climate location (≥ CZ 6).
Image
The ventilation space in this vented over-roof keeps the roof cool to prevent ice dams over the unvented attic
Image
These interior storm windows have low-emissivity coatings to let in light while keeping out heat in the summer and keeping heat in in the winter
Image
These snow guards help to keep snow from sliding off the roof and injuring people below.
