Energy Saving Features
High Performance WindowsAdvanced Wall SystemsIntegrated Heating
High Performance Windows
Glazing – Low-E coating to reduce heat loss
Gas fills– Space between panes is filled with non-
conductive gas (commonly Argon)
Insulating spacers– Insulating spacers between glass panes prevent
heat loss around edges of window

Argon filled space Insulative spacers
High Performance Windows cont’d
Frames– Higher insulation material
Window type– Casement and awning windows generally
provide a tighter seal when closed than vertical or horizontal sliders.

Advanced Wall Systems
Advanced Wood Framing Systems– Fewer wooden studs in the walls reduces thermal
bridging through the wall Insulating Concrete Form (ICF) Systems
– Insulating foam blocks that are filled with steel reinforcing and concrete
Airtight Drywall Approach (ADA)– Drywall and sub-flooring sealed together to
prevent air leakages and painted with vapor-retardant
Insulated concrete

Integrated Heating
Heat Pump Systems– Draw heat from outside or fluid filled coils underground and
pump it inside– Electrically powered
Demand Water Heaters– No hot water tank– Use hot high efficiency heaters whenever the taps are
activated Radiant In-Floor Hydronic Heating
– Water is heated in a boiler and run through tubing embedded in the floor.
