Commercial Building Envelope Energy Solutions

Window air conditioning units typically have gaps and holes around window sashes and around the unit itself that are often some of the largest direct connection points between the interior environment and the outdoors in a building. Left in year-round, window AC units can be a significant source of wasted energy.

The primary surface that separates the conditioned spaces from the unconditioned attic is used as the air barrier in a building where insulating the flat attic surface is optimal and can be a major source of energy inefficiency. Bypasses that connect the conditioned space and unconditioned attic need to be blocked and sealed to create an effective air barrier.

One of the most impactful solutions to improving energy efficiency is ensuring proper insulation in a building. Building insulation products such as spray foam, blown-in and batt insulation can help maintain energy efficiency and lower heating and cooling costs, making buildings more efficient and comfortable year round.

Doors, windows, and wall assemblies are installed in rough openings in the shell of the building. Installers often do not properly seal the perimeter of the window in the rough opening prior to installing the finish casing and trim. The pathway between the perimeter of the unit and the rough opening in the shell of the building is often large because doors and windows are regularly “shimmed” into place in out-of-square openings.

Often, installers do not properly seal the perimeters of doors, windows, and other wall assemblies that are installed in rough openings in the shell of the building prior to installing finish casing and trim.

Doors are often installed out of square or out of plum. Installation weaknesses, poor weather-stripping product selection, and deterioration of weather-stripping products create air leakage pathways around doorways. Proper weather-stripping materials and installation practices can provide a durable seal. Along with energy benefits, improving weather-stripping is often a deferred maintenance item and can have comfort benefits for occupants.

When windows are installed out of square or out of plum, installation weaknesses as well as wear and tear from many years of service create air leakage pathways around windows. Weather-stripping products available today provide a durable long-term seal.

Since Hopper windows are designed so that the top of the sash will swing inward from the wall when opened, it can create operable and energy efficiency issues. V-seal weatherstripping can be installed to minimize those issues.

The roof-wall intersection is a significant contributor to overall building air leakage. The top of the building is critically important because pressure differentials between the inside and outside are greatest at the top of the building. The roof-wall joint is one of the largest air leakage pathways and wraps the entire perimeter of the top of the building. The roof-wall intersection is often accessible above suspended ceilings and as a result, sealing this intersection can be an extremely cost-effective measure (high savings potential and relatively low cost).

Window film can strengthen the insulating properties of windows to create a more efficient barrier to external temperatures. By adding window film, occupants increase efficiency by turning a single-pane window into a double pane and a double-pane window into a triple pane. This improved insulation ensures occupants stay warm during the winter and cool during the summer.
