In the built environment we have reached such low energy consumption that energy conservation no longer should have the highest priority. On the contrary, investigations have shown that further decreasing the Energy Performance Coefficient (EPC) does not result in lower energy consumption. This is mainly due to the behaviour of the consumers. So, only if we succeed in changing the mentality of the consumers it would make sense to promote measures to lower fossil or other energy consumption. A further substantial limitation of the environmental impact can better be achieved by strongly reducing the quantity of construction waste. This is not only of importance for the demolition phase; the construction and exploitation phases are equally important. In the year 2000 the total amount of construction waste in The Netherlands reached the record value of 22 million tons. This means almost 1.5 ton per citizen per year! Of these 22 million tons about 6 million were ‘produced’ during the construction phase. Roughly speaking this is 10% of the new building materials paid for by the contractor (and the owner). They ended up in the waste container. A rigorous solution of the waste problem would also have a positive effect on other environmental factors. This is especially true if we consider the depletion of natural resources and energy consumption. A very good contribution to such a solution is given by IFD technology: which stands for Industrial, Flexible and Demountable.’
