A Passivhaus with NO South facing Windows??!

[Robyn Berry]

Has anyone ever built a Passivhaus with absolutely no south facing windows?
Seems like sacrilage to me but i've been posed the question by another so am hoping the knowledgable amoungst you may be able to answer this question?

I'm not talking about on a big build where communal heating contributes a lot, but on a single plot in its own right.  Thanks for any responses given!

In the southern hemisphere?

Very good Dave!!

I believe there are examples in Germany but will be larger buildings or terraces to get a very favourable form factor. Whilst Passivhaus is not heavily reliant on solar gain it is part of the energy ballance.

With phpp it it very quick to get an answer to such questions for a specific site and building.

Another concern woukd be how to get the daylight without lots of east and west glazing (winter heat loss and summer overheating issue) or excess North glazing (lots of heat loss and some summer overheating risk from late pm sun.

Passivhaus asside, not ideal.

Just visited Mike Whitfield's latest passivhaus project which has road to South. Still went for the windows and will use internal blinds. Nice to have that winter sun even if there is no nice view that side.

Haha thanks Dave- if only we could relocate the site! Thank you Nick for the advice also, i will get to modelling some scenarios!
