Low Impact Materials Essay

Overall there are numerous environmental factors to consider with the construction of the skyscraper from the ‘AllHigh’ company. These factors determine whether or not this proposal is beneficial, whilst also meeting the needs of the society and the environment. Although many disadvantages were present, other alternatives and recommendations are needed to potentially reduce the level of impact and hopefully mitigate some consequences.

Decades ago, sustainable construction was not even a common term for construction processes and uses of construction materials are chosen on how it makes an impact on cost savings

Rammed earth is a building technique which has been used for hundreds of years. The technique involves earth (similar to cob) which is compacted, in-situ, between forms which are created by shuttering (Figure 12 & 13). This creates a monolithic wall which is strong and durable with a variety of colours, depending on the earth within the site. Two or more soil components must be used to create the correct size appropriate wall (Windstorm & Schmidt, 2013:402). The walls are mainly 300 – 600mm thick and can be free-standing and, unlike cob, load bearing (Hall & Djerbib, 2004:281). The final product does not need any further finishing such as plastering and can be left to expose the different layers of earth. Post-industrial materials such as brick, tile and concrete can be recycled by adding it to the mixture, this will enhance the colour and the strength of the walls, the materials can also add to the fire safety of the walls. This method of recycling alongside the use of rammed earth can have an even greater and more positive effect on the environment (Hall & Djerbib, 2004:367). Rammed earth also has the highest density and compression strength of all earth construction techniques and therefore a more efficient material when it comes to structural qualities in construction. To increase the structural qualities of rammed earth, small amounts of concrete (5 – 10%) is added to the mixture (Mačková & Spišáková, 2015:133). Due to the high compressive strength the chances of erosion

Energy consumption and carbon emission data is available from an inventory file containing relevant values for a variety of building materials, which has been given to the author

Due to the environmental impacts of the built environment, there is a developing understanding of the need to improve the sustainability, energy efficiency and the total performance of new and existing buildings. Thus, the construction industry is required to develop its processes to meet the progressively challenging performance targets to encourage and secure sustainable investments, mitigate the impacts on the environment and satisfy buildings occupiers (BSRIA 2014a).

As a Construction Economics student, you need to be aware of the different types of materials used during the construction process. The purpose of this tutorial is to explain what we encountered during our site visit.

Foam balls lightweight concrete (FBLWC) has been a feature in the structural construction owing to its advantages over the normal weight concrete (NWC). It is a concrete weighing substantially less than that is made using gravel or crushed stone aggregates. Lightweight aggregate concrete is usually chosen for structural purposes which its use will lead to a lower overall cost of structure than will be expected with normal weight concrete.

Earthen construction has evolved with mankind and creates housing opportunities world-wide. Building with stabilized compressed earthen bricks (SCEBs) is becoming more popular due to the low cost, relative abundance of materials, and quality product performance. The majority of developing countries are today faced with an ever increasing problem of providing sufficient yet low-cost housing in sufficient numbers. In the last few decades, shelter conditions have been worsening: resources have remained insufficient, housing demand has increased and the urgency to provide immediate practical solutions has become more critical.

This report is only considered on the materials what is available in New Zealand and comply with nz standard and building codes.

The many-sided quality and flexibility to various climatic conditions far and wide necessitates the requirement for cautious nearby plan and obviously the outline of the framework is pivotal for the execution of the building. At the point when planned legitimately they can give both enhanced indoor atmosphere and lessened utilization of vitality in the meantime and when composed and built well, with experts and experienced producers like Thermos ash, the framework is sufficiently adaptable to meet climatic changes for most sorts of building use.

It is common practice in construction of slabs for residential and commercial buildings to use permanent internal formwork, which is the use of nonconcrete materials to reduce the material costs when pouring the slab. Common practice is to use polystyrene blocks to offset the amount of concrete used however it is possible to utilise tyres in the place of polystyrene blocks furthermore it is possible to use site generated waste that would require to be disposed of using other means.

My love for this field began when I interned during my third year of B.Arch. summer holidays in Habitat Technology Group in India. In their buildings, the spaces and walls were made using a method called compressed stabilized rammed earth construction. The construction was cost effective and very energy conscious. Numerous sustainable strategies we could adopt like to have more cluster buildings to open zones and protect natural habitat. Parking area could be limited. Usage of waterless toilets fixtures-low
