Icon & Proverb
This icon represents energy being stored in a container for use later on, while the proverb “make hay while the sun shines” reminds us that we have a limited time to catch and store energy.
Photo Story
Aldinga Arts EcoVillage, near Adelaide in South Australia, has some excellent examples of passive solar passive design.
This terrace house has a bluestone ‘Trombe’ wall on the inside of the building, which stores heat from the sun while it is low in the sky (during the cooler months). Cool air from inside the house flows in through a vent at the base, heats up and returns inside via a vent at the top. The one-way flaps in the vents can prevent cooling at night and are closed off in the summer when the heat is not needed.
Another example of this principle is the catching and storing of rainwater from the roof of the house into the tank on the right of the picture. This tank is tall, so that gravity can provide water pressure, and it is placed near the garden to reduce the hoses and pipes needed for irrigating. The garden itself stores energy too, in the form of food, which can be eaten straight away, or preserved for later on.
See photolog for other illustrations of this principle |
