Zero Carbon Design Technology Samples †MyAssignmenthelp.com

Question: Discuss about the Zero Carbon Design Technology. Answer: Introduction: The report aims to analyse the various aspects of Zero/low-carbon design technology. This technology focuses on the transformation of the energy, agriculture, industry and forestry systems to reduce the rising of carbon emissions. The pressing challenge of climate change is addressed through such technologies and paves the way for achieving net zero carbon emission society. The report discusses the usage of low carbon materials in construction of zero carbon buildings, innovative construction methods and method of management of energy consumption. The design opts for renewable energy resources and reusing as well as recycling of greenhouse gases. Zero/low-carbon design technology low carbon construction materials: low carbon building products has been used in innovative constructions. These are mainly recycled materials and by products. Low-carbon bricks: this material has been implemented in mass production since 2009. Fly ash helps in reduction of embodied carbon that cane be found in normal bricks. it is fine glass powder consisted of silica, alumina and iron. Fly ash is a by-product of burnt coal from electricity production and is usually disposed after separation from flue gas (Allwood et al. 2012) Green concrete: The raw materials that are used to form the conventional concrete are substituted with the recycled materials and by-products of industrial. granulated blast-furnace slag and fly ash can substitute carbon intensive cement. Washed copper slag can substitute sand and granite can be substituted by recycled granite. Green tiles: this is a ceramic material made of minerals and recycled glass. This product transforms the waste glass to tiles that are used in building floors and cladding. Recycled metals: the process of producing metal products is very carbon intensive. This life cycle procedures of metal outcome can reduce energy consumptions (Williams et al. 2012). Repeated recycling of metals does not hamper the properties of the metals. Beside this the metals can be re-melted and new products can be formed by re-moulding. For example, shipping containers can be reused in building construction. Innovative construction process: In introducing energy efficiency improvement in constructing buildings, it involves in forming the idea that the carbon emission through the supply chain can form a larger proportion of that building's lifetime footprint (Cabeza et al. 2013) There are some methods such as- Reduction of material quantity used Selection of materials, which are associated with low emissions factors for example recycled materials Selection of material suppliers available near to the construction area Diversion of demolition wastes to recycling Management of carbon emission throughout the construction supply chains measuring the footprints of every product to identify the carbon intensive areas and focusing the efforts on reduction carbon emission. building a carbon strategy as well as implementation plan (Verbong, Beemsterboer and Sengers 2013). introducing plan for sustainability throughout the life of the building. Management of operative energy consumption and consumption behaviour: In zero carbon design of a building, the energy consumption is reduced through building construction strategies. The sustainable designing of building construction includes- air tightness replacement and upgradation of window that help in high level of insulation maximisation of natural ventilation by using openable windows that will both reduce overheating and increase ventilation. Use of solar shading and controlled glazing to reduce solar gains Reduction of artificial lighting. Energy efficiency can be increased by using energy efficient lighting, underfloor heating, creating management system to monitor lighting, heating, cooling and ventilation. The renewable energy generation can help in management of operative energy consumption (De Jong et al. 2015). The zero carbon design technology aims to produce same quantity of energy that is consumed. It can be applied in all new as well as existing buildings. It can be also applied on the buildings those have limited on-site renewable energy capacity like the buildings having dense urban setting. Thus the design offers net zero energy property and eliminates energy bills. Concerns of increasing energy wastes and carbon emission reduction are fast growing among the consumers therefore, the developers are also taking interest in building such constructions (Shafiei and Salim 2014). The prices of zero energy model homes are marginally higher than its normal counterparts but its energy saving concept has created the platform for a fast growing market. Choice of renewable energy systems: Many institutions and companies are viewing green electricity or powers from renewable energy sources the best way to reduce atmospheric impacts of their activities. It is a complex issue to determine that which renewable energy resource will be more beneficial on climate change, which includes political as well as environmental aspects (Budzianowski 2012). Low carbon power is a technology or process that produces power with emitting lesser amounts of carbon dioxide than that of conventional fossil fuel power generation. The zero or low carbon design technology includes such assolar power,wind power,hydropowerandnuclear power as low carbon power generation sources. . It also includes fuel preparation and decommissioning. The design excludes fossil fuel plant sources but describes a particular subset of operating conventional power systems, which are successfully coupled with aflue gascarbon capture and storagesystem. Recycle and reuse: The petrochemical sector and chemical sector are the largest energy user. They are accountable for 10% of total energy demand and 7% greenhouse gas emission. 95%v manufactured products depend on chemical and petrochemical industry (Tavoni et al. 2012). The chemical technologies as well as products are used in energy saving appliances therefore these industries also have important role in saving greenhouse gas or carbon emission. These are used in insulation, lighter materials of automobiles, efficient lighting and advanced products for renewable technologies (Aresta 2013). The scientists therefore are currently working on identifying the methods of scaling up carbon reductions in the chemical industries and increase the reuse on greenhouse gases. The technologies chiefly focus on carbon dioxide conversion. To the researchers, CO2 reduction has posed a great challenge because of its molecular inertness. The usage of Nano needles helps to attract CO2 and speeds up reduction of carbon mono oxide (Leung, Caramanna and Maroto-Valer 2014). The low or zero carbon technology offers a considerable way to produce renewable as well as carbon neutral fuels by recycling CO2 to Dimethyl Ether and Methanol. Conclusion: Therefore, form the above analysis it can be deducted that the low and zero carbon design technology addresses both the problems of mounting energy need as well as solving energy challenges. The technology opens up possibilities of storing the alternative energies and increased usage of renewable energies such as wind and solar energies instead of conventional fossil fuel power generation.
