6 Designing a passive house building

7 Passive house requirements Compactness: Two buildings the same floor area!

8 Passive house requirements Compactness: Two buildings the same floor area! Junctions!

9 Passive house requirements Compactness: Two buildings the same floor area! Equal glass area Junctions!

10 Passive house requirements Compactness: Two buildings the same floor area! Solar shading Equal glass area Junctions!

11 Architectural results Compactness Minimal entrances Optimal placement on the site Solar shading
