SUSTAINABLE CONSTRUCTIONSUSTAINABLE CONSTRUCTIONNew homes only make up about

2% of the national housing stock so the main challenge is to improve the mass of older housing.

New homes present an easy opportunity to build with minimal environmental impact and maximum health benefit.

SUSTAINABLE CONSTRUCTIONSUSTAINABLE CONSTRUCTIONThis has been recently formalised

in the new Code for Sustainable Homes and in the tightening of building regulations.

The Austrian Supreme Court classed PVC as "an environmental poison".

60% of poly vinyl chloride is produced for use by the construction industry.

Chemical phthalates contained in PVC leak out and are banned from certain baby toys in the UK.

out the use of PVC in their building stock.

In addition, Nike, Volvo and Ikea are taking steps to minimise the use of PVC in their production lines.

Alternative plastics are available.

Less desirable materialsLess desirable materialsIn addition to the chemical

content, PVC also contains heavy metal fillers such as cadmium and lead.

All of these materials give rise to concern about the potential harm in the case of house fires.

CementCement"Cement manufacture is very

polluting and is responsible for between 7% & 10% of all global Co2 emissions.

This is the result of a "double whammy" - firstly the ingredients have to be heated to very high temperatures (1500c), which takes a lot of fossil fuels;

which takes place in the kiln also releases Co2. "In addition, all the big cement companies are now

environmental impact of quarrying the clay.

On the other hand, because brick is very durable it is possible to recycle it to be used again.
