There is an increasing concern regarding the environment. Global warming, caused by the build up of 'greenhouse' gases such as CO2, is one of the most serious threats our planet has ever faced. Most people and organisations are now well aware of the importance of saving energy in the running costs of buildings but what consideration has been given to how much energy is used by the individual materials that go into their construction?
The Timber Research and Development Association (TRADA) has published a report which has revealed some startling facts about the amount of energy required to produce individual building components. Research into a 'Green Building' examined the energy impact of buildings on the environment by comparing the individual elements. It took into account all elements from mining of the original materials, felling the timber and all stages of manufacture right through to the product leaving the factory gates. The resulting total of energy used expressed in kilowatt-hours (kWh), being the same units used on electricity and gas bills, is known as the Product Energy Requirement or PER. Refer to illustration overleaf.
In today's more energy conscious world, timber frame construction methods offer an option which is not only more time and cost effective, but is also more energy efficient. Compared to alternative building materials such as steel, aluminium or concrete, timber requires very little energy to produce, creates no harmful waste and is, above all, the only natural renewable resource.
ALL timber used by R. Brown & Sons is obtained from sustainable managed resources where reforestation programmes ensure that more trees are planted than are felled. New trees actually produce more oxygen than do old trees and also absorb more carbon dioxide thereby helping to create a cleaner and environmentally better world in which to live.
