This is the inside of one of the units of the Medford house. The south-facing side of the house has many windows to let in light, cutting down on the need for artificial lighting. In the winter, the sun is also a source of heat. This brick wall acts as a thermal mass to collect and store that heat. The floors are built with gypsum concrete to collect and store solar heat as well. The wood on the staircase landing and many other locations is fir planks from the house before the deep energy retrofit.
