A comparison of building rating systems: Leed, Green Star, BREEAM. A proposal to integrate Biomimicry into Green Star Rating
In the last two decades the western society has gained a greater commitment towards sustainable infrastructure due to the acknowledgment that the sector should not continue to operate “business as usual” in a fashion of neoclassical economics that promotes profit making and the intensive use of natural reserves without internalizing ecological damage.
Furthermore recent improvements in the world’s sustainability agenda have set objectives to promote the diminution of Green House Gas (GHG) releases as an urgent concern. To be able to accomplish this, higher building industry principles have been put into practice in regards to building design and operation to quantify different grades of performance. In this regard, it is important to develop an adequate sustainable building framework in Australia in order to be leveled to international standards.
Additionally, this endeavor attempts to research new strategies for sustainable infrastructure, which are consequential from the Biomimicry principles applicable to building design and building operations. This new discipline must be taken into consideration as it clearly presents innovative solutions for generating a more sustainable architecture in Australia. Biomimicry introduces a new capable resolution to this problematic.
The importance of Biomimicry in the building sector lies on the fact that it is an inspirational fund of valuable new innovation and, consequently, offers a wide range of possibilities to construct a pathway towards a regenerative building industry that co-exist with nature.
* To identify the constraints that Australian sustainable accreditation visages in developing a sustainable infrastructure by making a comparison to international assessment rating techniques, specially from the United States and the United Kingdom frameworks, – LEED (Leadership in Energy and Environmental Design) and BREEAM (Building Research Establishment Environmental Assessment), respectively.
* To develop a framework that takes into account Biomimicry principles in building design and operations in order to foster resilience and innovation in the building sector for sustainable development.
According to Garnaut (2007) the building sector is the largest donor to the world’s greenhouse gas emissions (GHG), utilizing approximately 40 per cent of the world’s energy and producing approximately 30 per cent of the carbon emissions. In Australia, only commercial and residential buildings have a share of 23 per cent of Australia’s national greenhouse gas emissions.
At the same time, sustainable development has become the “buzzword” of both the academic and the business world. In particular it is possible to identify two trends in sustainable buildings in the last two decades. The Period 1990 – 2000: where the concept of sustainable design was mainly based in the notion of buildings being “eco-friendly”, “environmentally friendly” and “unobtrusive”. A crucial element for building performance during this phase was founded on a “cost efficient” evaluation. The Period 2000 – 2010: the start of the 21st century reveals the beginning of “calculating carbon” and “measuring efficiency”. This phase has established the measurements of CO2/m2/year as common factors in assessment of buildings performance. The principal indicator on building performance during this phase was based on a “carbon emission” analysis. The sustainability phenomenon has resulted in an abundance of frameworks around the world to evaluate property development against a collection of “sustainability criteria”. Green Building Councils are members of the World Green Building Council; and on its respective country are conformed by partnerships between government and private organisations that have worked in...
