1.BRICKS

y B y the middle of the 16th century,brick making had become a distinctindustry competing with stone as astructural material.

y

Reuseabley Durabley Negligible embodied energy if

sourced locally y No toxic emissions from a

manufacturing processy Diverts demolition waste from

landfilly Issues concerning quality assurancey The Demolition Protocol states that

bricks have a recovery potential of 10% - rising to 100% in somebuildings.



2.RAMMED EARTH

y Rammed earth walls (aka pise) are constructed by thecompacting (ramming) of moistened subsoil intoplace between temporary formwork panels. Whendried, the result is a dense, hard monolithic wall.

y In recent years, rammed earth has become popularamongst environmentally-conscious architects

y Distinct appearancey Natural and readily availabley Low embodied energy (a level similar to brick veneer

construction)y Unstablised earth is reuseable post-demolitiony High moisture mass, hygroscopic - helps regulate

humidity y Use of local soils supports sustainability practices.y High thermal mass (though work is still underway to

quantify its extent)y

Airtight construction achievabley Traditional form of constructiony Modern methods are widely tried and tested overseas

eg Australiay Concerns over durability requires careful detailingy Poor thermal resistance external walls require

additional insulationy Not all soil types are appropriatey High levels of construction quality control are

required



3. bambooy As wood becomes more scarce

bamboo construction will holdmore and more value outside of thetropical climates where the benefitsof its use have been known forcenturies.

y Bamboo construction falls into thecategory of being environmentally friendly as the plants are extremely fast growing in comparison to trees.

y Being such an extremely fastgrowing grass means that

harvesting takes place every 3-5 years as opposed to more than 25 years for softwoods and over 50 years for many hardwoods tomature.



Cork

y Cork material is harvested from the cork oak(querbus?) tree

y the bark (or outer skin) of the tree is peeled off, andthe tree is left to regenerate,so no need to cut down

whole tree.y when applied as flooring, does not look like a "memo

board" at all, but has sleek lines with a strong

durability.y A perfect alternative for heavily used areas like

playrooms and work areas.y A s Thermal Insulation, cork historically was used in

refrigeration applications, such as in the walls of freezers

y Impermeability Since the inter-connected pocketsof air are truly so tiny and microscopic,

y Softness the pockets of air compress and thenexpand again, never collapsing within the product

core, giving the cork a resilience and memory.y Design Flexibility the beauty of the cork raw

material is that it can be cut in numerous ways thatenable veneers of differing aesthetics to be made intohighly decorative surfaces.

y Slip resistance cork, due to the softness andbounce-back, is very slip resistant



Engineered lumbery A product created from small-diameter,

fast-growing trees rather than old-growth timber

y It turns small pieces of wood, combined with adhesives under heat and pressure,

into strong, light, straight structuralmaterials with good characteristicsy There's no need to use whole trees, large

trees, or old trees to produce engineeredlumber products

y In fact, engineered lumber is made withabout half the wood fiber of solid-sawn

wood

y it's not necessary for a builder tocombine multiple, standard-size lengthsto create a beam that stretches across atall wall, a wide ceiling, or the floor of ahuge room as engineered lumber isstrong which means less cutting on siteand less waste heading to landfills.



Conclusion

y So for the benefits of our own welfare, environmentalfriendly decisions in selecting materials are important

in order to preserve the balance of the nature, toprotect the living creatures, and also to protect yourheath. All of us do have this responsibility,

It starts by YOU
