Eco Friendly Construction Methods and Materials

posted 14.09.2009
Here at recipro, we have recently come across this intersting article on the Sustainable Build website.  The article looks at eco friendly methods of construction and greener building materials.  Here at recipro, we believe that the reuse of surplus materials can greatly benefit the environment, but there are lots more things people can do.
There is an urgent need to address the great challenges of our times: climate change, resource depletion, pollution, and peak oil. These issues are all accelerating rapidly, and all have strong links with the building industry.
There is a growing consensus from scientists and the oil industry that we are going to reach peak oil in the next twenty years, and that we might have reached this point already. Global demand is soaring, whilst global production is declining, and oil is set to become increasingly expensive and scarce. The building industry is hugely dependent on cheap oil, from the manufacture and transportation of its materials, to the machinery and tools used in demolition and construction. In the UK, it uses vast quantities of fossil fuels, accounting for over half of total carbon emissions that lead to climate change. The built environment is also responsible for significant amounts of air, soil and water pollution, and millions of tonnes of landfill waste. This is a situation that clearly needs to change.
Reducing Energy Consumption
With the inevitability of declining fossil fuels, and the threat of global climate change, reducing our energy consumption is an essential survival strategy. Choosing to build green saves energy. The low embodied energy of green products ensures that very little energy went into their manufacture and production, with a direct reduction in carbon emissions. Eco friendly design methodology can further reduce energy consumption by minimising energy inputs for heating, cooling and light, and incorporating energy efficient appliances. Saving energy for the occupant also saves money - an issue that will become increasingly important as the cost of fossil fuels inevitably rises in the near future.
Building Healthier Homes
Eco-friendly construction can not only help to create a better outdoor environment, it can also help to build a healthier indoor environment. Conventional building materials and methods have been linked to a wide range of health problems. Chemical pollutants from paints, solvents, plastics and composite timbers, along with biological pollutants such as dust mites and moulds are known to cause symptoms such as asthma, headaches, depression, eczema, palpitations and chronic fatigue syndrome. Green buildings eliminate these problems through good ventilation design, breathable walls, and the use of natural, non-toxic products and materials.
There are many good reasons why we should use eco-friendly construction methods and materials. It can improve the health of our planet, and the health of our own lives. It also supports local business and helps strengthen the local economy, which in turn helps to build our communities into vibrant, prosperous and desirable places to live.
A Necessary Choice
Green building is not only a wise choice for our future; it is also a necessary choice. The construction industry must adopt eco-friendly practices and materials that reduce its impacts, before we reach a point of irreversible damage to our life supporting systems. The UK Government is beginning to recognise this urgency, and is committed to integrating green specifications into building regulations and codes, but the process of developing policy is slow. The industry needs to take its own initiative and find alternative ways to build, using green, renewable energy resources, and adopt non-polluting practises and materials that reduce, recycle and reuse, before it is too late.
