3 MAIN IDEAS
- Temperature
- Light (Sunlight has disinfectant qualities)
- Strength
Q: How is using cement and steel (common building materials) a problem?
A: The problem is due to industrial carbon emissions. The single material responsibke for the most emission is steel productions which produce 25% of the carbon emissions, followed by cement, which produces 19% of carbon emissions.
5 SUSTAINABLE MATERIALS
1. WOOL BRICKS
2. SOLAR TILES
3. SUSTAINABLE LIVING (hemcrete?)
4. PAPER INSULATION
5. TRIPLE-GLAZED WINDOWS (there is air between the three layers. and because air is a poor conductor of heat, not much heat passes through.
ALTERNATIVE: Timber
HEMPTECHNOLOGIES
- Hem is the crushed stems of a plant called "hemp". It can grow up to 4 metres high and it dries naturally the sun.When it grows, it takes in carbon dioxide.
- It is baled and transported to the factory.
- fibre is seprated from the shiv in the factory
-"hemcrete" is mixed and lined between the tiles.
- coated with like to prevent hemp from decaying.
- the hem can then take in carbon dioxide from the surrounding air (( hem will not release carbon dioxide as it wont decompose as it has already been coated with lime))
- walls are left to dry
