The Green School in Bali, Indonesia was founded by John and Cynthia Hardy, environmentalists and designers from Bali. The campus spans over 8 hectares divided by the Ayung River, with classrooms on one side and housing on the other. All buildings use sustainable materials like bamboo, mud, and grass roofs. Over 25,000 bamboo poles have been used to construct buildings like the Heart of School, a large bamboo structure connecting the areas divided by the river. The campus aims to be a model of sustainable design with organic gardens and integration with the natural environment.

2. •The Green School with its affiliates the Meranggi Foundation
and PT Bambu were founded by John and Cynthiab Hardy,
designer and enviornmentalists from Bali ,Inodenesia.
•The Green School creates a sustainable campus straddling
both sides of the Ayung River in Sibang Kaja, Bali. The campus
is situated in a lush jungle with native plants and trees along
with sustainable organic gardens.

3. Climatic Conditions
•Lying along the equator, Bali has a tropical climate, with two
distinct monsoonal wet and dry seasons. Average annual rainfall
in the lowlands varies from 70-125 inches.
•Humidity is generally high, averaging about 80%. Temperatures
vary little throughout the year; the average daily temperature
range on the island of Bali is 26-30 °C (79-86 °F). The Green
School site is located at Latitude -8.548 and Longitude 115.136.

4. Building Data
•Total site area -103,142.63 square metres
•Ground floor area - 5,534 square metres
• Total combined floor area (ground floor and upper floors) -
7,542 square metres.
•Green School with its affiliates PT Bambu and Meranggi
Foundation was founded by John and Cynthia Hardy,

Project Description

5. •This project involves multiple communities in the production
and the transformation of bamboo into buildings and later,
peoples behavior.
•Farmers plant and harvest the bamboo; local artisans transform
it into material for construction which then supplies the master
builders.
•The project serves as a model of sustainable ecological building
and replicas are already in planning to benefit other
communities around the world.

6. Evolution of Design Concepts
Response to Physical Constraints -
The Green School is located on both sides of the Ayung River.
Their sustainable approach to both campus planning and
campus building requires greater attention to site infrastructure
and its integration into the physical site. At the Green School,
bridges, pathways and steps traverse the steep hillside linking
various parts of the school programme.
Response to User Requirements -
The Green School campus is a giant laboratory experimenting
with innovative ways to address sustainability
Purely Formal Aspects-
There are many generous roofs and very few walls and windows.
The large roof overhangs protect the spaces from driving rains
and hot sun. The roofs are covered with alang alang which is a
local material used for vernacular domestic buildings.

8. Green School
The buildings on the Green School campus are distributed over 8
hectares of land divided by the Ayung River, whose western bank
supports classrooms, libraries, laboratories and a cultural arena,
while the eastern bank serves as the setting for the school’s
kitchen, faculty housing, and guest villas. The land is designed
throughout the vast campus with shaded walkways, elegantly
curving steps traversing the rugged topography that is blanketed
by farming activities such as aquaculture ponds, rice fields and
organic vegetable gardens.

9. All structures are built with sustainable, natural materials such
as traditional earth walls, bamboo and alangalang grass,
restricting the use of cement to primarily below ground. Up to
this date, about 25,000 Petung (structural bamboo) and 18,000
Tali (roof rafters bamboo) have been used in the Green School
buildings.

10. •The Heart of School is truly an amazing bamboo structure.
Started in October 2008 and completed in May 2009, the building
reflects the expertise acquired throughout earlier projects on
campus and as such is worth being mentioned.
•It is located on the main cross roads of the campus, close to
everything and attracting the passage of many people. On its
poles, more than five hundred and twenty names are carved,
representing the donors supporting the Balinese scholarship
program.
