Window framing
10 of 12 from Photos: A Passive House in the making
In a superinsulated house, insulation can be put on the outside walls, which means that windows need some special treatment. The plan here is to create shutters that can retain heat during colder times. The placement of windows was done with thought, too. The north side here has a small window while there are large glass doors in the back on the first and second floors. Those south-facing windows will bring in heat from sunlight during day hours to help heat the building. A concrete floor will serve as "thermal mass" to store some of that heat.
