A material that has thermal mass is one that has the capacity to absorb store and release the sun s heat energy its density and levels of conductivity help to keep the internal temperature of a building stable.
Thermal mass flooring for passive solar shed.
Very high levels of thermal mass e g.
Objects that have thermal mass have inherent qualities for both heating and cooling.
In simple terms a passive solar home collects heat as the sun shines through south facing windows and retains it in materials that store heat known as thermal mass.
Thermal mass is a property that enables building materials to absorb store and later release significant amounts of heat.
The share of the home s heating load that the passive solar design can meet is called the passive solar fraction and depends on the area of glazing and the amount of thermal mass.

Flooring choices for use over concrete slabs using thermal mass what finish flooring materials are best to use over a concrete floor slab to retain the thermal mass properties of the slab.
Flooring materials for passive solar floor slab designs where direct solar gain and passive solar heat storage are desired.
This is very important in a passive house in terms of heat control from solar gain as it moderates temperature fluctuations.
I was planning on an engineered wood floor but my builder pointed out that this would prevent the sun from heating the slab.

Internally the concrete slab and brick walls provide thermal mass to stabilise temperatures all year round and the long roof extends out over the car port at the west side of the house providing additional shading from the hot afternoon sun in the summer.
