R2000 Houses Energy Saving Features

High Performance Windows Advanced Wall Systems Integrated 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 spaceInsulative 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.
