Sustainable construction techniques
Sustainable construction is a building method that promotes resource efficiency and the minimisation of environmental disturbance. Also known as green building this type of construction considers a lifecycle approach to the entire process, from design and construction through to the actual running of the building. It also promotes the use of sustainable materials to be used in an efficient manner and designs that minimise the use of energy, water and other resources over the entire life of the building.
The sustainable construction movement has evolved from the knowledge that the ecological footprint of a building can be substantial and it is necessary to reduce the negative environmental impacts caused during construction and operation. Although many residential homes are now becoming more sustainable, green building techniques initially began in the commercial sector. Green buildings were better for the environment, but they also provided greater financial returns and improved working conditions for the people using it. Sustainable construction has subsequently permeated all types of buildings with many governments now regulating the need for its use in all new buildings.
There are a range of sustainable construction techniques now available, each suited to a different type of building application. The following techniques will focus on residential buildings but many can be applied to other building forms. As material use is a significant cause of environmental impacts addressing this element of construction is important. Sustainable construction techniques promote the use of renewable or recycled materials whenever possible. Materials should also contain less harmful substances such as volatile organic compounds (VOCs), which create a healthier environment inside a building. Sourcing materials locally can reduce the amount of greenhouse gases produced by transportation and support local businesses.
Another technique adopted is the minimisation of resource use during the buildings eventual operation. This starts at the design stage, which should utilise the surrounding natural environment, such as solar energy and breezes. Building eaves that block the summer sun keeps a building cooler, while still allowing the winter sun to enter. Insulation will also provide a more stable interior temperature throughout the day and night. This will reduce the need for additional heating and cooling, saving money and greenhouse emissions.
The techniques described above are only a fraction of the types of sustainable construction methods now used in the residential building sector. If you are building a new home, remember to start thinking about sustainability from the beginning. Ask your architect and builder for their input and make sure they adopt sustainable construction techniques during both the design and building process. By incorporating sustainable construction your new home will be better for the environment and provide a safer and more comfortable place in which to live.
