Please, Help

Dear Friends and Readers,
I am writing to ask for your help to support the medical treatment of my younger brother Pierre Roring. He is suffering from a life threatening cancer on his neck. The tumor is very big and he cannot eat solid food.


We are trying to raise fund through gofundme for him so that we could send him to a hospital that has got modern equipment to treat cancer patients in a big city in Indonesia. Here is the link for donations:

We also ask for your prayer to God to help and heal Pierre in his fight against cancer. You could also help by sharing this message to your friends and other people.
Thank you for your donation and message of supports.
Best Wishes,
Charles Roring

Tropical house Ventilation and Air Filter System

How should the ventilation system be installed in a tropical house?
Jalousie Ventilation
In tropical region, the average temperature is usually higher than in sub-tropical region. However, the humidity of the air is high. A tropical house has to have enough ventilation holes to let air flow smoothly into and out of the rooms of the house. The cheapest ventilation system that can be installed or made in a tropical house is the jalousie windows which ensure the passive coolings of the house. Jalousie is the most efficient ventilation system but it has to be covered with mosquito net to prevent mosquitoes from entering the house particularly the bedrooms.


Natural Air Filter
If the house is located near a busy street, the air around the area will be mixed with smoke and dust. Smoke contain toxic gases. If possible, the ventilation holes should not be constructed facing the street. The jalousie windows can be made on both sides of the house. However, such arrangements are often impossible to be implemented. Most of the houses in big cities share wall on both sides of the houses and the only walls that function as ventilation system are the front and the rear ones. To reduce the number of dust from entering the house, finer net has to be installed on the jalousie holes (above the windows) and curtain and be installed on the jalousie glass windows. Another way that is very effective in reducing the amount of dust is by planting flower plants near the windows and decorative trees at the front yard. The leaves, branches and twigs and shrubs of the plants will be able to filter the air creating a healthier living environment.
Today, house design software such as Archicad has been used by architects to design houses that is more integrated to the environment using its eco-designer features.
