Architects design buildings according to the needs of their clients; every building is constructed with a specific objective. It is imperative to ascertain whether a building has been able to achieve the desired objective or not. It is understood that construction of buildings and other structures involves utilisation of materials that are responsible for environment pollution. Of late, due to global awareness on preservation of environment, role of buildings in carbon emission has been investigated.In only 3 hours we’ll deliver a custom Achieving Sustainable Building essay written 100% from scratch Learn more
Global environmental scenario is deteriorating day by day. Construction industry is one of the major contributors to environment pollution. It is reported that nearly half of the carbon emissions are caused by construction sites and concrete structures around the globe. It has become crucial to invent ways and means to decrease such carbon emission. Another problem that is escalating is use of energy resources by the construction industry. Water and electricity are the two main energy resources without which the construction industry would come to a standstill. Since construction is an industry, owners, builders, contractors, and other people and agencies involved in this field want to earn profit from their construction ventures. Latest technology is used in order to reduce carbon emissions and utilization of energy resources and this involves huge funds. The three main issues i.e., increasing profits, maintaining sustainability and reducing carbon emissions can be achieved by adopting appropriate sustainability features in the construction industry.
In pursuing the guidelines of green buildings, cost factor is a major hindrance. As such, owners of new buildings demand new construction methods that are cost-effective (Tolson 2011). New construction methods have allowed buildings to comply with the guidelines of the green building concept but at the same time, cost of construction has increased manifold.
Strategic innovation is a venture adopted by the global construction industry in order to cope with rising costs of construction. Such innovation includes carbon-green technology that aims at reducing carbon emission in new buildings being constructed (GVA 2011). Inclusion of carbon-green innovation in government guidelines becomes more important due to the fact that it serves a dual purpose: low cost of construction and adherence to carbon emission restrictions. Buildings that adopt this innovative measure qualify for government incentives and subsidies (in various nations) that also include tax-cuts (Chan & Cooper 2011; Adamson & Pollington 2006). Such measures by the government reduce financial burden on owners and contractors.
Rationale of the study
Construction sector plays an important role in the positive growth of economy of any nation and contributes substantially to its GDP (Zhou & Lowe 2003). Construction sustainability is an important aspect in the current undertaking of construction projects throughout the world. An up to date and efficient infrastructure works significantly towards promoting growth, with the construction sector playing a key role in ensuring that built structures are not only inventive, but also effective in terms of cost. Sustainable construction involves ensuring sustainable development during construction. It is the process of applying appropriate practices in selection of materials to be used, their sources, design and method of construction, as a way of improving performance, reducing environmental project burden, minimizing waste and enhancing ecological friendliness (HM Government 2008).
According to Bon and Hutchinson (2000), main methods of dealing with various challenges include; ensuring governance through set standards, regulatory and legal practices as well as developing and implementing policies that are market-focused. Successful completion of any project requires that all quality measures are put in place (Khalfan 2002). Such factors necessitated to conduct this study.Academic experts

How can sustainability be achieved by buildings while maintaining minimum cost of construction?
Starting with a brief introduction, the problem faced by the construction industry and the rationale of the study were discussed. The author identified the research problem and formulated a research question. Scholarly articles and journals were referred on the subject and a literature analysis was done that incorporated some of the works of eminent scholars. Subsequently, the methodology of the study was discussed. Since this study is based on the green building concept, it was important to include a case study. The author researched about such buildings and selected 60L Green Building located in Australia. A thorough research was done on the building and a case study was prepared. The case study discusses the important factors related to the selected building such as design, cost-effectiveness, compliance of government guidelines, etc. Finally, the limits and constraints of the study were discussed before writing the conclusion.
Case Study: 60L Green Building
The 60L green building is an example of highest level of construction of commercial buildings, especially those that adhere to the green building concept. The building is located at 60-66 Leicester Street, Carlton, Victoria and houses the office of Australian Conservation Foundation (ACF), in addition to other tenants. The building was initially a warehouse (during the 19th century). The warehouse was renovated into the present unique structure. Most of the material was reused during the renovation process. 60L green building depicts commercial feasibility of a structure designed and operated in such a way that it has minimum possible impact on the environment. The building specifies the manner in which an intelligent builder can attain objectives. The building also shows how occupants can augment productivity.

How is 60L Green Building different?
The 60L Green Building has set noteworthy standards for environment friendly buildings as far as utilization of energy and water and greenhouse emissions are concerned. Use of electricity for lighting purpose has been reduced by more than 80 percent, consumption of electricity by equipments has been reduced by 2/3rd and that for heating and cooling has been reduced by almost 60 percent. In comparison to a usual commercial building, long-term cutback is 65 to 70 percent on an annual basis. As a result of using non-fossil based fuel sources CO2 emission savings reached 100 annually. Rainwater harvesting has resulted in an annual accumulation of 500 kL of water to be used for shower, utensils and other washing needs. Employing appropriate and energy efficient appliances and fixtures, utilization of water in toilets has been reduced by almost 60 percent. The used water is recycled within the building premises to be used for flushing and irrigation purposes. Such intelligent measures have resulted in annual water saving of 90 to 95 percent. The following figure depicts the flow of air and how it has been used for positive effects in the 60L Green Building.
The 60L Green Building has a negligible impact on the environment due to its adherence to all the guidelines prescribed by the Australian government. Since the building lays stress on minimum of use of energy resources and maximises reutilization of such resources, it is considered to be a very cost-effective building. The following figures depict the potable water and sewage treatment systems being followed at 60L Green Building (Farrelly & Davis 2009).
