Effectiveness of this System

(1) > (2) > (3) > (4) Cost of this System

(1) < (2) < (3) < (4)

The above illustrations mean Essence (1) is cheapest and most effective. If you practice (1) and (2) then you have best cost performance



Actually (1) and (2) are so effective, building can keep night time temparture even during day time. (3) and (4) uses temperature difference day and night so become not so effective. Our temperature difference day and night are 5 to 6 degrees, need more difference for (3) and (4). There is merit to have (3) and (4), I'm happy with I could make it, But cost performance are not good.



My recommendation is just practice (1) and (2). Those are amazingly effective.



Anybody can come up with those ideas but nobody actually tries yet. So I think I should do that. Because any idea not tried actually are not practical. I volunteer to become a scapegoat for this project.



My house has become rather big and odd looking so based on my experiment ,I made a plane which I think ,best passive solar house fit for tropical areas.



People here are making concrete house with plan copy from Western countries which are not fit for tropical areas so end up using much energy to cool their house or just bear in hotness.That is rather ridiculous. We should make standard for tropical areas.



I'm now out of budget so somebody should build this house for trial. Be a next scapegoat, but I'm quite confident that you can make the next generation of the standard Passive Solar House for Tropical Areas.
