Thailand’s Green
International School

Leading the way to provide modern schooling with a low carbon footprint.

The earliest visions of Krabi International School were to be a self-sufficient school and to work together with our environment as much as possible. We had a mission to become a modern green international school with an initial goal to become fully self-sufficient within 5 years of opening.

Now after only 2 years we are already close to accomplishing that goal and therefore want to take green schooling to the next level by heavily mixing in technology and innovation into the heart of our school vision. Schools are often the centre of the local community and we want to take this a step further to be able to literally provide power and organic produce to the surrounding areas.

With the help of some amazing people we are already well on the way to this heightened vision. In April 2017, the Steenbergen family of New York partnered with us to aid the installation of our first Solar Energy power system. As part of this partnership, Krabi International School has opened up another place in the Steenbergen Scholarship program to educate, free of charge, a local Thai child.

Our largest step towards our vision is the installation of our solar power system. However, power is only part of what we are doing to become self-sufficient. We also have a responsibility to pay it forward to the local community and to the next generation, please see below for more details:

Solar Power

With the installation of the 13.25kWp solar power system we can say that we are possibly the first International School in Thailand to use the Sun as its main power source.

The Steenbergen family of New York have provided us with funds to purchase and install a 10kWp power system and Solaris Green Energy. in conjunction with IBC SOLAR who have donated an additional 3.25kWp system to increase the total peak power to 13.25kWp.

Due to school hours we will actually produce far more power over a year than we use. We are working with the local power producers to allow this excess power to be fed back into the grid and thereby helping the surrounding area to also reduce their carbon footprint.

Rain Water Harvesting

Rain Water
As we are based in the tropical country of Thailand we have an abundant amount of rain fall and even during the dry season we have the occasional downpour. We aim to catch and use this rain!

All over the school grounds there is an elaborate network of above and below ground catchment systems using roof and ground gutters, French drains and underground piping to redirect the majority of our rain water into a main underground pipeline that feeds into the main storage reservoir next to our sports pitch.

Water Storage Reservoirs

The main storage point for the rain water will be the 1,500,000-litre reservoir situated at the end of the sports pitch at the lowest point of our property. Additionally, we have a 600,000-litre reservoir higher up on the property that supplies, via gravity to whole school.

The main lower reservoir, once complete will also be populated with fish to help provide nutrients to the water within its own small ecosystem. This nutrient rich water will help irrigate our farm areas and provide water to our hydroponic farm with the aim to become truly organic.

During the day, a solar power pump slowly but constantly pumps water up to the top reservoir. A basic particle filter removes any solids before going into the top reservoir and from there the water either goes in raw form for general irrigation or to the hydroponic farm. At the same time the water takes another route through filter systems so it can be used within the school. Further micro filtering and treatment brings this water to a safe drinkable standard.


Hydroponics Farm

Hydroponic farming reduces water usage by 80% over conventional farming. We are currently experimenting with NFT (Nutrient Flow Technique), Flood and Fill, and Bato Bucket systems.

Our first vegetables have been tomatoes and we are now starting lettuces, cucumbers, peppers, chillies, egg plants, potatoes, onions and carrots.

Once fully operational we will be able to supply our staff and students with freshly grown organic vegetables. Excess vegetables will to available to parents and visitors to purchase in the school Café.
