Natural Warmth and ColdThe greenhouse on top of the building not only cleans the air, but it also collects a lot of warmth from the sun. Inside it’s at least 5°C warmer then outside. In winter this warmth is very welcome to bring the building on temperature.

in summer, the greenhouse is covered by sunshades to protect from overheating. In addition, underground cooling tubes are used to cool down the air, and dehumidify the humid summer air.

Bringing the sun insideDaylight is not only healthy and nice, but it’s also an inexhaustible lightsource. That’s why the happy healthy school has tall and wide windows, to catch as much light as possible. A happy, healthy and energy-efficient solution.

Sunlight has one disadvantage, on a sunny day it can overheat rooms with much glass in the façade. That’s why a system for blocking direct sunlight is integrated in the façade. Horizontal planks keep the direct sun from coming in, while as much indirect sun in passed through, and also the view to the outside is maintained.

Sustainable materialsIn order to achieve the highest level of sustainability, different materials were considered. Bamboo is a local material in China, so not much energy is used for transportation. Also it’s one of the fastest growing plants on earth; a great example of sustainable forestry.The Bamboo is used in different ways. It’s used in massive rods and pillars for construction, hollow bricks that can be stacked into walls and raw bamboo is used in the façade. A big advantage of using bamboo is that no waste is created. May the building once be deconstructed, the bamboo can easily be composted and return to the biological cycle, or be safely burnt for generating new energy. Also the green concept gets more readable from the building when using bamboo.

Cradle to CradleThe design of the Happy Healthy school has a lot in common with the ‘cradle to cradle’-concept, a method for sustainable design by Michael Braungart and William McDonough. The concept of the building can be summarized as: ‘a building that gives more functionality and happyness to the user, without using brutal force to do so’.The building is built with local materials, which can be reused or transformed into clean energy.Building a Happy Healthy School in Shanghai or any other big city brings a green plot to a concrete environment, in other words: It makes the city more green.
