Compactness vs. solar gain: Minergie vs. Passiv-Solar
- courtyard types (Innenhof) max favor alternative to Minergie-P buildings -> preferably Minergie-A
- Compact buildings with low room depts = good use of daylight
- basically, the current building codes and Minergie today still promote a compact construction
- the importance of lighting energy also shows that overly compact buildings are increasingly inefficient overall
- Consequently it is possible to realize a building with a comparatively poorly insulated building shell, yet still achieving a very low primary energy requirement thanks to efficient building technology
