Building a home that utilizes passive solar for both heat and cooling
The following is word for word as written, and the English isn't perfect, but I have left it in the original format of the writer. You can hear the accent come through in his slightly broken english-written words, but it is nice to feel his story from his perspective. Notice the professional video above uses the same design principles that have been incorporated into many homes in the past, as well as some from the one below. So often, two homes are built next door to each other, and they may be of similar size. The one whose builder may have been wise to passive solar design has an $80 per month electric bill while the other a $200.00 electric bill. The two residents can't figure it out, but there is wisdom behind the madness, and that's what we are here to understand:
I am Japanese and I live in Leyte, Philippines. The normal daytime temperature is average about 33 degrees Celsius (91.4 Farenheit). So that got me thinking... How can I live cooler, how can my house stay cooler especially during the summer months.
Here in the Philippines, there are only two types of houses available. One is the local Nipa Hut, the other one is the concrete type.
Nowadays, wooden houses are almost impossible because It's not find good quality of woods and if we can find some, it's too expensive.
Nipa hut is made of Palm leaves for roofing and coconut lumber or bamboo for walling. This type of house best fits for tropical countries but it's not durable and it needs constant maintenance. On the other hand concrete houses can easily adopts heat during daytime and retain heat at night. So I'm thinking on how to make concrete houses cooler than usual.
To build a Passive Solar House, One big advantage to live in tropical areas is We don't need to think about cold winter season. It might lot easier to make house.
I live in the local area of Leyte and people are not familiar in building a Solar House. Resources here are very limited so simplicity is the best. so I thought of using only conventional ways of building techniques, no high technologies nor sophisticated tool and equipments.
To make it very simple, I decided to make one side sloop roof (heed roof).
Essence of this Solar House
- 1 In front of the house should face to the North side so that sun will not hit north and south side of the house with eaves.
- 2 Double Wall and Roof to protect direct hit from the sun to the building, cover east and west side of the wall and the roof.
- 3 Use airflow, hot air going up and cool air going down, It cools the house effectively.
- 4 Bring cool air into the basement at night and use daytime for cooling rooms.
