all energy on-site without needing to tie to a utility grid. I’m
not intimately familiar, but a number of zero-energy building design challenges
exist in the academic world – you may find a lot of information from
competition entries if that’s what you’re looking for and such information
is archived somewhere. Zero-energy may also refer to “source”
energy (meaning the energy harvested/generated on site meets a higher bar of
energy to include losses of transmission/generation), but I’ve yet to see
that applied to a real project.</span></p>

<p class="MsoNormal">I'm looking for examples and analyses (including LCA) of
energy autarky buildings. As I want to see the differences in design as a
function of the climate, the examples may be fom anywhere. There seems not
to be that much of literature on the subject, so any nice reference is welcome
too!</p>
