Sustainable Housing and Urban Construction

Since the beginning of time, the build milieu has been an integral part in providing shelter take for men, women and children. Maslow (1943) formulate that shelter is a basic requirement of humans. In the future, humans testament beget to construct sustainable shelter otherwise would they would risk depleting resources for subsequent generations. Construction is an example of a multitasking activity. The lifecycle of face can be unkept into phases. Achieving bodily structure sustain might in modern environment requires a better apprehensiveness of environmental impacts.Impacts much(prenominal) as climate stir, associated costs, as well as utilising benchmarking scale to measure across a whole range of make types and occupancies. This report will discuss building sustainability, the constraints that stake holders of built environment face, and the role of architects in the process of constructing sustainable buildings. Conceptually, sustainability is allowing present gen eration to garner its pick ups without depriving later generations of a way to visualise theirs. jibe to Meckler (2004), building sustainability means to yield a safe, healthy, comfortable indoor environment plot of land simultaneously limit the reduction of the earths natural resources. Architects, with their strange position within the built environment, atomic number 18 well equipped to meet the challenges of sustainability in the built environment. The building and kink industry possesses a proud ability to be innovative (Meckler 2004), and through this innovation that it would create refreshing methods and processes resulting in constructing improved sustainable buildings that can be serve as subsequent years benchmark to beat.The expression industry has invested in research and development into sustainability in order to gain a cle ber brain the effect of building on the environment and reducing the impact of buildings on the environment. The common goal is to be expertness efficient. Being zero efficient does not equate to being cipher sustainable. The nada from the handed-down fogey sources cannot be supplied without using further considerable amount of energy in supplying it.The efficiency of the energy lifecycle starting from the raw declension of resources, preparation, transport, conversion and distribution to application may be up to 20%. To equate this in simple terms is that it takes approximately 5kWh to deliver 1kWh of energy for employment. So in order to consume 1kWh of energy, the real term consumption is actually 6kWh. Numerous studies internationally have shown that operational energy consumes the primary(prenominal) amount of total energy use in buildings during a natural service lifespan of approximately 50 years.This accounts for about 8595% of total energy use (Thormark, 2005). From a residential perspective, there should be a focus more on the sustainable development of the residential buildings and urban constr uctions. The fundamental reason overbold and more energy-efficient technologies continue to be ignored and the technologies that are applied rarely perform as efficiently as they should is because of a lack of accountability for building energy murder in current building bod and operation practices.The building and construction industry in Australia has made significant progress forward in the last 5 years to improve their environmental performance. This improvement has been in response to increased attention from topical anaesthetic and state government policies regarding to ecologic sustainable Development (ESD), as well as the availability of holistic environmental rating tools much(prenominal) as the young Building Council of Australias Green Star rating tools. Architects factor in climatic variables into their thoughts as they design and plan houses, premises and buildings (Alnaser & Flanagan 2007).In hot dry regions such(prenominal) as in the Northern Territory, the b uilt environment should be intend compactly to reduce the amount of surfaces exposed to solar radiation. In fiery humid regions such as in Queensland, buildings should be openly set-apart to maximize air movement between individual buildings. This would reduce the structure operational energy consumption and maximise Green Star rating. Green building is a tremendous growth area in design, construction and building corporeals. Green building has gained momentum due to the rise in energy costs and cost of building materials.The happy medium is just aboutplace between a combination of passive measures through optimal building design and active measures achieved through efficient mechanical system intentional to control the indoor climate. These active measures mentioned above include utilizing renewable energy, such as solar energy, wind energy and geothermic energy, improving thermic performance of building structure, utilising daylight and energy efficient lightings, and devel oping new sustainable building materials (Thormark, 2005).Another aspect of sustainability that is often neglected is favorable sustainability. Social sustainability can be thought of as qualitative indicators that equilibrate the development process. Some social sustainability marks are to provide adequate local services and facilities to serve the development, to provide housing to meet the needs of the population, to provide postgraduate tincture, habitable developments and where possible to preserve local culture and heritage. In any actual development, there is a need for other reinforcement elements to make it appealing and sustainable.An integral part of the development is to provide high quality energy efficient buildings for community activities such as musicals and outdoor(a) space for open markets. By having such gatherings, the community will give-up the ghost a sense of ownership and will utilise the facility frequently. A salient aspect of sustainable developme nt is to provide a swagger of housing structures of all different types (Zhu & Lin, 2003). In order to achieve the objective of providing affordable housing designs and construction must be of high quality and yet utilises minimal resources.Wherever possible, cultural heritage should be keep through the reutilising of local valued buildings. If cultural preservation is achieved, the architectural design for the developments will reflect local heritage and use local materials. According to Williams and Dair (2007), there are 9 commonly identifiable barriers to achieving sustainability. Some of these barriers are 1. Sustainability measure was not considered by stakeholders 2. Sustainability measure was not required by client (includes purchasers, tenants and end users) 3. The sustainability measure cost too much (in some cases the investor would not fund)Unless sustainability is on the agenda of the local planning government, stakeholders are marvelous to voluntarily put sustainabil ity measures on their agenda. Stakeholders were simply bypassing sustainability issues altogether. As with most local government planning policies, there are strict guidelines regarding social objectives, such as meeting housing needs. If a policy is active at the forefront of development then they appeared on stakeholders agendas. Many architects have the ability to succeed in achieving a higher star rating for energy efficiency for their built environment projects.They have been doing so for a while. The challenges of sustainability in the future should not be construed as extra attachments to how architects have intentional in the past. Architects have the inherent ability to go back to the selective service board and to reinvent the design process to reflect the buildings needed for the future. Architects have a vital role to play. They are a part of place decision making mechanism in the building and construction industry. waiver forward, their role will be inextricably lin ked to producing sustainable outcomes. at that place are many indicators for sustainable building design (Smith 2001). (a)Identifying possible sources to soften renewable electricity on location, i. e. like Building-Integrating Photovoltaic (BIPV). (b)Minimal usage of fossil fuel energy sources used during the lifetime of the building. (c)Ensuring that building management systems are user friendly simple to operate. (d)Implementing passive or active solar energy while employing heating system and cooling systems which are fine tuned to the needs of the occupants with air-conditioning used only in exceptional circumstances.As we progress into the future, the need to provide shelter increases due to population growth. The building structures needed for this developing demand have to be environmentally and socially sustainable. There is a global increase in awareness of the diminishing supply of tralatitious fossil fuel resources. Fossil fuels make up the core heating and cooling e nergy consumption presently. In order to achieve sustainability and grant the next generation able to meet their needs, there are concisely term increased economic costs as the transition from conventional dependent on fossil fuels to alternative energy sources.These barriers have to be overcome and the role of the architect in the overall schema is exceedingly important. They possess the necessary design skills to adapt to the changing needs and conjure sustainable commercial and residential . REFERENCES N. W. Alnaser_, R. Flanagan (2007).
