We create a sunroom in the small rear courtyard in the home. We incorporate vents in the north end to encourage warm air to flow through the sunroom and into the house. This form of passive heating works extremely well in heating the house through the sun for free. In winter, we cover the clear polycarbonate sheeting with shade cloth to keep out unwanted summer heat. The sunroom is also a passive clothes dryer and an ideal spot for a hydroponics garden.

So we are going to build a sunroom here and that will act as a passive solar heater for the house. Construction of the sunroom is fairly simple. The clear polycarbonate roof is supported by a metal frame which is mounted on the courtyard and garage walls.
Well, we have just finished the sunroom by adding a large sheet of polycarbonate and already we can feel the warmth in here. It looks like it is going to work extremely well.
A key aim of the sunroom is to maximise winter warmth being absorbed into the concrete slab on the ground floor.
Well, it’s a sunny July day, the outside air temperature is around 13 degrees, inside it is 23 degrees. The sun room really works, that’s a staggering 10 degrees hotter and it’s already starting to warm the house.
By opening up the sliding door on the rear of the house and the louvers on the north end of the sunroom we allow air in, it warms up and heats the house.
We also increase the heat reaching the polished concrete slab. This heat is then stored in the thermal mass of the concrete helping to keep the house warm after the sun has gone.
The sunroom is also a very effective passive clothes drier so in winter on those wet washing days we actually save electricity as well.
