UNICO heating and cooling


If you look very carefully you can see the heating/cooling system in the ceiling of the dining room (Top left and the rectangular slot ... click the picture to get a bigger view). This time I've 'boxed in' the ducting.

This shot was taken hours after the walls got their plaster skim. In my system, the UNICO system uses a single hydroponic radiator in front of fan and ducting system to heat the house.

On days when it is too hot the system blows cool air from the shaded north wall. A further modification to the UNICO system (under development) is a CO2 control system to add fresh air when needed. So far the CO2 levels are too low to trigger a control valve. Another addition to add is a passive heat exchanger to transfer the heat from exiting stale air to the incoming fresh air. The heat exchanger and Co2 monitor can be green thing 8 out of my 10 and we shall call it "Only change the air when you have to".

So when I have finished the UNICO system will provide:
  • Heating
  • Cooling
  • Air quality control
  • Passive heat distribution

Green thing 7, no skips


It's been a while since I uploaded a current picture of the SIP (structural Insulated Panels) house, so here is a picture. We could call this green thing 7 as its shows no skips. Where possible I use everything. For example, where I use to two layers of plaster board to create wiring channels, the first layer is all the off cuts. Broken tiles are used for rubble under the decking and the list goes on. It is time consuming, but I guess thats why people create so much waste. We are all in a hurry.
