A new home built with
an energy efficient building envelope can pretty easily become a net zero home by adding on PV.
However, a new home that does not have
an energy efficient building envelope may meet some arbitrary current code requirement, but will never become a net zero home — unless it later has the additional expense of undergoing a DER.
According to building professionals, the solution to achieving
an energy efficient building envelope is to focus more on the roof.
The cottages are built using structural insulated panels for floor, walls and roof, creating an extremely
energy efficient building envelope.
Fox Blocks Insulating Concrete Form Wall Systems provide an extremely
energy efficient building envelope offering superior strength, sound, air quality, and well insulated walls.

Ventilation is particularly important in
energy efficient buildings with tight
envelopes.
More than three decades ago, Craig was designing and

efficient to begin with.
From an exergy efficiency perspective,
building technologies which rely on solar, wind and biomass
energy sources, coupled to thermally
efficient envelopes, appropriate fenestration strategies [where we put what kind and size of windows] and natural ventilation / cooling are truly more elegant than «cutting butter with a chainsaw.»
The air - tight
building envelope is paired with an
energy recovery ventilation system, which ensures a flow of clean air for improved ventilation,
