Dictionary: describes a product that has been designed to do the least possible damage to the environment
US EPA – EPP program defines as: “ products or services that have a lesser or reduced effect on human health and the environment when compared with competing products or services that serve the same purpose...”
Waste from construction and demolition produces a massive, virtually untapped, sustainable resource. Salvo estimate that only 1% of building materials are currently from reclaimed sources. Whereas some 5-10% of the building materials demand could potentially be met from reclaimed. (Salvo, A Reclamation Protocol, 1995). Diverting and re-using salvaged materials from the waste stream maintains them as a high grade resource instead of down grading them by crushing or chipping.
A study commissioned by the nanotechnology group of the UK's Department for Environment Food and Rural Affairs (Defra) looked into the policy implications of nanotechnologies that will benefit the environment.
Five nanotechnology applications were subject to detailed investigation: fuel additives, solar cells, the hydrogen economy, batteries and insulation.
No easy methods for insulating solid walled buildings, which currently make up approximately one third of the UK’s housing stock.
Nanotechnology may provide a solution which, if an effective insulation could be found with similar properties to standard cavity insulation, could result in emission reductions equivalent to a maxim potential of 3 Mte per year.
Ultra thin films on windows to reduce heat loss already exist on the market. There are claims that nano-enabled windows are up to twice as efficient as required by current building standards.
However, industry believes that significant further insulative savings in glass maybe made instead using aerogels, which themselves are nanostructures.
The ISSE is evaluating and commissioning research via nanotechnology and reclaimed materials technologies for a solution to the increasing level of environmental damage caused by the construction industry
