Insufficient knowledge of sustainability

Discuss About The Grass Innovations Sustainable Development.

Despite the urge for the promotion of sustainability within the construction sector, there exists a number of challenges affecting construction projects. These challenges include the following:

Insufficient knowledge of sustainability. It was realized by many researchers that most actors within the field of construction possess limited information relating to sustainable behaviors within the sector (Kotabe & Murray, 2014). Nevertheless, effects resulting from evaluation of cultures, poverty, shallow research and engagement in new and emerging ideas and issues are some of the major trends in sustainability implications. According to Warren-Myers, valuation plays a primary role in implicating investments in sustainability as valuers mostly don’t include the aspect of sustainability in their evaluation reports.

Another key challenge is the common behavior of assuming and insufficient implementation of sustainable concepts in the construction field. Since construction is a global practice or activity, individual countries witness distinct implications (Elkington, 2014). It is thus advocated for a joint push of embracing the agenda of sustainability in developing countries due to the rising urbanization and construction activities in these regions.

It entails principles that aim at eliminating negative environmental effects efficiently through the adoption of a skilful and sensitive design entailing high integration levels, the involvement of the neighboring community, adoption of precautionary behavior, equity within and between generations and consistent and continual improvement.

Integrity- adoption of the integrity principle of sustainable design and planning involves the adoption of the below-listed channels of behaviors or actions:

Emphasizes on the human rights and the advantages or importance of mutual existence under a healthy, supportive, sustainable and diverse living conditions

It acknowledges the need of interdependence (Daly, 2010). The human design elements solely depend or relies on the services provided by the natural world with wide and resulting implications for the consumption of the natural resources. Hence, the need for design considerations expansion with an aim of acknowledging the beyond impacts.

Respecting the existing relationship between matter and spirit. All settlement aspects should thus be considered, for example, industry, dwellings, community and trade in the relation to mutual existence and the continued growth in connections involving spiritual and materially soundness.

Taking responsibility for the outcome challenges originating from the decisions relating to design on the wellbeing of the human, existence of the natural component of the environment and their coexisting mandates or rights (Redclift, 2012).

Adoption of sustainable principles

Coming up with objects or structures with ultimately high values so as not to burden the future generations with high maintenance and or danger prediction in protecting the neighboring generations. This is prevented through consistent careful construction and designing of products and structures.

Doing away with the waste concept. Keen analyzing of life cycles of products is required before there use in the construction and come up systems which result in limited or no wastes

Complete understanding of design limitations and complications since no manly creations exists forever and that design phase does not necessarily have to solve all problems.

Sharing of knowledge and information seeking to trigger constant improvement (Girard & Nijkomp, 2013).

Community involvement- the principle of involving the neighboring community during the design of the sustainable housing project assists the society to understand the need and importance of environmental and resource protection. They will eventually facilitate the implementation of the proposed sustainable project objectives as they simultaneously understand and embrace the need for mutual existence.

Precautionary behavior- the adoption of precautionary conduct principle aids in avoiding the consequences that could physically be experienced in the occurrence of a risk. This is achieved through risk assessment technique which is based on the protection of future generations in terms of maintenance and repair expenses.

Equity within and between generations- since one of the main goals of the sustainable construction project is usually ensuring a balance between the current and future generations, it is thus important taking note the principle of equity between both generations so as the future generations do not suffer the environmental consequences caused by the current regime or generation.

Continual improvement – this principle mainly focusses on the consistent improvement of sustainable projects through knowledge and information sharing between all involved parties. It aims at prevention of sudden collapse in sustainable construction projects through continuous and consistent improvement hence reducing the future general costs of repair (Daly, 2015).

Many building materials pose several distinct strengths and weaknesses during the construction phases of a sustainable project. In general, when settling on a material it is more important to choose on a material that suits the prevailing climate of the construction site. Hence, when the selection of building materials should efficiently allow easy and faster thermal efficiency for the prevailing cooling and heating processes within the project.

In addition, a suitable material to be adopted for a construction project should be easy to handle. It should be easily modified to satisfy the contract specifications and desires. Similarly, it should be obtained sufficiently with the budgeted costs and its accessibility to the place of need should be a priority for the designers. Nevertheless, this material must not be in a capacity to allow movement of water or humidity to other regions of the construction structure as this would encourage weakening of the structure (Honey, 2012). The selected material should again pose minimal waste products and in case of little presence of the wastes, it should have the recycling capabilities so as its parts that cannot be used for the intended purpose can be utilized in other activities thus avoiding wastage. The origin of the material should also encourage mutual existence in that acquisition of this material should not lead to permanent destruction of the environment and interference to other components of the environment.

Integrity principle of sustainable design and planning

Finally, the selected material should encourage limited embodied energy and thermal transfer of energy. In extreme conditions, the thermal energy conduction should balance with the embodied energy. The material should also not be a position to react with paints, adhesives and treatments as this would facilitate weakening of the building through the formation of fractures. Despite all these factors, it is of importance identifying the scenarios of adopting a particular material over the other in consideration of the prevailing weather or climate conditions.

A good number of this techniques revolves around the evolution or developments in materials acquisition that is aimed at waste, energy and varying difficulties at the construction sites (Dempsey et al, 2014). The following are techniques that tend to have high impacts amounts in achieving sustainable construction project goals:

Prior fabrication of construction materials in particular conditions of the environment. Fabrication of construction materials after careful cutting and shaping of the materials which is aimed at limiting the waste products aids in minimizing lots of losses which be experienced such as a constant change in shape which frequently results from the cold weather conditions. Similarly is the insulation of the panels used in the construction project.

Construction waste management. Management of waste products through its reduction and avoidance is this day almost an easy task for contractors. Proper management of waste creation helps in minimizing the cost of construction as the obtained limited waste products are applied in other uses within the construction site relieving the contractors the cost of obtaining a material for a similar purpose.

Site management for improvement of the environment. Proper handling of the construction site has progressively achieved in the construction sector. It has led to controlled water, air and environmental pollution as emissions and waste products are controllably emitted to the environment (Rahman, 2013). Specific policies have been enacted to regulate the exploitation of certain materials with an aim of managing their effects on the environment relating to pollution. Policies have also been generated requiring for silt fencing of the construction site in order to prevent runoff pollution. Organic waste control is also regulated through the use of garbage containers.

Lean manufacturing aimed at reducing energy. This is focused on identifying the activities in a construction site that encourages waste production to inform of both energy and resources or materials and doing away with them. This technique has resulted to procedures within the construction site that aims at performing certain tasks and processes in a shortened duration of time in relation to the normal way of conducting the same process for a similar output. The technique is also applied in informing all sub-contractors and site operators of their duties prior to the task in order to prevent wastage of time and confusion. The desired materials are also delivered in appropriate time and condition eliminating losses from damages, time wastage and theft at the site.

Community involvement

Material selection. Architects are encouraged to obtain materials that have been developed from the recycling of products and local sources. These materials are commonly generated from the renewable sources hence limits the cost of construction. They are commonly used in the installation of water saving flush toilets and other water features which in turn reduces the water consumption. Similarly, sustainable materials are obtained and utilized for the construction purposes (Seyfang & Smith, 2017). The products should conform to the good thermal requirements and satisfy environmental sustainability. During the acquisition of a new equipment, a special operator should be available who understands how to use the equipment. This is achieved through training of the available workforce on the constant changes and rise in the equipment’s use which should also be environmental protective oriented. Introduction of new equipment must again conform to the policies involving material and equipment used in a construction site. Eventually, the cost of obtaining the new material should be affordable and efficient to both involved parties (Hopwood et al, 2015).

This mainly concentrates on water and energy consumption.  A sustainable construction project needs to focus on the utilization of renewable sources of energy rather than non-renewable energy sources. The following are the most encouraged sources of energy to be adopted:

Solar power energy. Energy generated from the sun is highly recommended since it is cheaper to harvest through the erection of solar panels at the roof of the construction project. Secondly, solar energy is reliable as it can be exploited easily. In addition, sustainable construction projects should be equipped with solar hot water heaters for the heating purposes.

Wind power. In addition to solar power, wind power forms another good option for generating energy. This is achieved through the construction of windmills which generates electric power from the wind action. The energy is stored through the use of capacitors as wind may not be frequent (Welford, 2015). This source of energy might be somehow slightly expensive to implement.

Hydropower. This forms the electricity obtained from a high speed moving water. The water in motion is used in rolling and turning turbines thereby generating electricity. This is the most exploited source of energy but for large-scale purposes.

Ocean power. This is also known as marine power. It refers to a renewable source of energy generated from the ocean tides and waves or ocean differences in temperature. The ocean water movement generates a kinetic energy which is in turn transformed into electric energy consumed in most of the sustainable settlements.

Precautionary behavior

Geothermal energy. A geothermal power is a power that is obtained from the ground by the geothermal technologies (Campbell, 2016). It also forms a good source of renewable electric energy for sustainability.

Cogeneration energy. This is an efficient and ecological power generating method entailing the use of wasted heat in power production to generate a renewable source of energy known as cogeneration.

Bioenergy. This forms a generation of energy from domestic animals wastes and plant manure. It is an efficient source of renewable energy mainly used for cooking and lighting purposes

When constructing a sustainable housing project, it is important to utilize the daylighting through the construction of windows and openings in regards to the normal positioning of the sun hence lighting the room while reducing on the energy consumption (Folke et al, 2012).

Rainwater. This forms the water utility collected from the rain. This water is harvested through the erection of water tanks. Rainwater can be used for all household responsibilities including bathing and drinking as the water is treated making it safe for consumption.

Greywater. This is water obtained from households from wastes which lacks contamination from faeces, I.e. sinks and showers. Since it is not extremely contaminated, it can be reused for toilet flushing and irrigation purposes after treatment (Berke & Beatley, 2017).

Blackwater. Blackwater mainly entails water obtained from toilets. This is the most contaminated waste inform of water as it contains more pathogens. It is normally treated and reused for mainly the purposes of irrigation.

In sustainable housing developments, wastes resulting from water usage should be minimized through using the exact amount of water to achieve the desired obligation. The resulting water waste should be efficiently collected, treated and reused appropriately (Irwin, 2015).
