What is sustainable construction and why is it important?
Sustainable construction takes account of these objectives in a balanced way at all stages of a construction project. Sustainability should be considered when first deciding whether a new building or piece of infrastructure is needed, throughout the specification and design, on the construction. sustainable construction. A range of models detailing principles of sustainable construction will now be briefly reviewed. Hill and Bowen  aggregated the principles of sustainable construction into four pillars - social, economic, biophysical, and technical. These are supplemented with a set of over-arching, process-oriented syairtogel.co Size: KB.
The construction industry, by its very nature, is a big user of natural resources. But with growing concerns over climate change and the finite nature of these resources, there is increasing pressure on construction firms to reduce their environmental impact.
While there are challenges involved in adopting sustainable construction methods, there are also great benefits too. Sustainable construction means using renewable and recyclable materials when building new structures, as well as reducing energy consumption and waste. These can include proper insulation to prevent heat loss, solar panels to reduce energy consumption, and building materials with a long lifespan.
From energy usage to emissions, the construction industry has a huge impact on the environment. Aside from the potential for building over wild habitats, the construction industry energy use is high. The heavy machinery used in construction still leans heavily on fossil fuels, and even inefficient electricity use can result in the unnecessary burning of fossil fuels further down the energy supply line. The fabrication and shipping of materials can have a great impact on carbon emissions.
Mining for raw materials can result in the pollution of local water tables. The manufacture of concrete has resulted in over 2. Construction can also result what are good pick up lines hazardous waste, and the improper disposal of such waste can result in pollution that affects not just the environment, but also the health of people living in that area.
There have been great strides made towards bringing renewable energy to construction sites. A popular solution is a modular battery system that can be deployed on-site and recharges via included solar panels. These batteries can power electric tools and vehicles, as well as as security equipment. Some of these systems can offset one tonne of CO2 per week and litres of diesel, resulting in a significant impact when they are used on large construction projects.
Adopting sustainable construction methods is not an overnight process; there are challenges to face, the greatest of which is cost. There will always be pressure on construction organisations to reduce costs where possible, but there are still concerns that sustainable construction methods will cost an organisation more.
But there are more tangible benefits too which will help you demonstrate the value of sustainable construction beyond environmental concerns. Construction firms can cite this data in tenders and help offset any additional costs that might result from a sustainable construction.
And building owners can look forward to a more valuable addition to their property portfolios, as well as the kudos that comes with operating a green building. And that potential kudos is greater than ever, with growing awareness and interest what is the price of a cadillac srx CSR, the idea that businesses should support good causes. And sustainable construction results in increased CSR for everyone.
The building owner is operating a green building. The people or businesses taking up residence in the building can point to their reduced impact on the environment. Sustainable construction methods can demonstrate CSR for a construction firm too, and it can be shared amongst the supply chain.
If your organisation only contracted suppliers that were committed to reducing their carbon footprint, for instance, this is positive PR for your organisation. The truth of the matter is that green buildings do come with lower operating costs. There are also direct savings available for your organisation; by reducing waste, for instance, you will reduce the fees charged by your waste management company. By adopting more efficient vehicles, you will save on fuel costs.

What is sustainable construction?
Sustainable construction can be viewed as a subset of sustainable development applied to the construction industry. It can de defined as “the creation and responsible management of a healthy built environment based on resource efficient and ecological principles” (Kibert, ). Concerns over the environment deterioration date back to. Sustainable Construction aims to apply the principles of sustainable development to the construction industry. Within LEED New Construction and Major Renovation, energy makes up the most points, though other aspects that create a sustainable building are very important. Understanding the major components of the Rating System and what they encompass is important for passing the test.
Papers People. An investigation on recycling potential of sulfur concrete. The rising concerns about the environment and sustainability are leading towards the need of recyclable materials to protect the environment and help in resource conservation. Sulfur concrete SC is a unique composite that does not Sulfur concrete SC is a unique composite that does not utilize water and energy intensively produced cement. As a substitute to cement, molten sulfur firmly binds aggregates upon hardening.
The sulfur concrete is recyclable and can be easily remolded in new applications. Moreover, sulfur is a by-product of the petroleum industry with almost zero carbon footprint. In this study, the mechanical compressive strength and modulus of rupture and durability properties water absorption, salt attack-resistance, acid attack-resistance and alkali attack-resistance of SC were evaluated after recasting without the addition of a new binder.
However, there is a drastic decrease in strength and durability performance after the second recasting. Save to Library. Low-grade glued laminated timber reinforced with FRP plate. Fibre-reinforced polymers FRPs are an accepted material by structural engineers for the strengthening of structural elements. With increasing environmental concerns, further emphasis is being placed on the use of sustainable With increasing environmental concerns, further emphasis is being placed on the use of sustainable construction materials such as timber.
This paper describes an experimental programme which examines the reinforcement in flexure of low-grade glued laminated timber glulam with a commercially attractive recyclable FRP. Unreinforced glulam beams, FRP plate reinforced glulam beams, unreinforced glulam beams incorporating an additional sacrificial lamination and FRP plate reinforced glulam beams, which had a sacrificial lamination bonded beneath the FRP plate, were fabricated and tested in flexure.
The unreinforced glulam demonstrated linear elastic behaviour and exhibited brittle tensile-flexural failures in comparison to the pseudo-ductile behaviour of the reinforced beams. The addition of reasonable reinforcement percentages strategically located in the tension zone resulted in moderate enhancements in the stiffness while more significant improvements in the ultimate moment capacity were obtained.
Strain profiles illustrated that increased utilisation of the compression strength of the timber is obtained when FRP reinforcement is included.
There is a strong premonition that a future successful sustainable construction implementation pivots partly upon a manifestation of sustainable construction understanding among the professionals in the industry. This research stands to This research stands to advocate that a distinct manifestation of sustainable construction concept by AEC professionals reflects the knowledge kept, which mirrors the understanding thus provides a plausible starting point for future successful implementation of sustainable construction practices.
Research data was gathered via a survey carried out on construction professionals. Findings from the structural model developed showed seven latent factors which includes awareness, political, passive culture, knowledge, demand, financial and attitude. The latent factors derived from this research provide a context-specific understanding of sustainable construction concept by AEC professionals in its indigenous setting as a basis for future implementation of sustainable construction practices.
The swiftly mounting world energy consumption has sparked questions regarding supply constraints, the collapse of energy resources, and dense environmental effects. Although the construction industry has much developed, yet construction Although the construction industry has much developed, yet construction is still a difficult, and costly process.
Consequently, there is a necessity to find additional energy-efficient and cost-saving substitutes to sustain the urbanization of houses at a reasonable price to low-income groups. This study aims to provide an energy-efficient proposal for a housing scheme with strict control over cost allowing the low-income groups to enjoy livability stemming from the thermally comfortable and cost-saving technology.
For this purpose, visits and surveys were carried out to critically analyze the respective housing scheme. Two proposals were suggested i. Proposal A by applying a low-cost technique called a Rat-trap bond to the walls and Proposal B, by designing an architectural plan for proficient utilization of space along with Rat-trap bond.
Summarized results were prepared from cost analysis and Ecotect analysis which ascertains the proposal to be energy efficient in addition to low cost. It is recommended to invest in cost-effective and energy-efficient technologies at the governmental level so that the challenge of inadequate housing can be answered once and for all.

Exploring sustainable construction: implications from Latin America. The outcomes and implications from the regional Latin America and the Caribbean Conference on Sustainable Building SB04 are considered in conjunction with the current regional context. To understand the development of a Latin American To understand the development of a Latin American approach to Buildings are an integral part for development in any sector of economic growth and they consume resources not only during their construction but also for operation throughout their life.
The design, construction, operation, maintenance, The design, construction, operation, maintenance, and ultimately the removal of buildings consume large amounts of energy, water, and building materials, and generate large quantities of waste, and pollute the air and water. The amount of resources consumed, waste generated can be judged from the fact that in any development project, the component of construction is quite large.
It is high time that the above said issues about the use of recycled material in construction in our country be addressed so as to achieve economy in construction coupled with easing burden on natural resources thereby resulting in cleaner environment. With the rapid development and modernisation, cities are growing at a very fast pace and the buildings are the main component of cities.
The manufacturing process of building material contributes to Green House Gases such as CO2 to the atmosphere to a great extent. The natural disasters like global warming, ozone layer depletion, unexpected seasonal variations and decreasing land surface have now moved the centre of attraction from development to sustainable development.
Since we have limited resources and energy, our development should focus on conserving the energy. Due to the continuous exploitation of natural resources, there is an urge to produce environmentally responsive building material for the construction of new buildings to meet the rapid urban growth.
Sustainable buildings are designed, constructed, maintained, rehabilitated, and demolished with an emphasis throughout their life cycle on using natural resources efficiently while also protecting global ecosystems. Selection of appropriate building material helps to use the energy efficiently. In the rapidly changing scenario of building sector, planners, architects, engineers and builders are looking for new materials and technologies to adopt in future constructions that benefits like energy efficiency, resources and water conservation, improved indoor air quality, life cycle cost reduction and durability.
This paper presents a brief study of sustainable aspects of building materials and a tool for Life Cycle Assessment criteria that helps in selecting proper building materials.
The process of development brought the revolution in the construction industry by innovation of new and advance building materials. The inventions were implemented until the environmental impacts disturbed and shivered the human life. Generally, energy is used for the extraction, transportation, processing of the building materials and assembling of the structures. Therefore, it is of great concern to reduce the GHG emission into environment in order to control adverse ecological effect. Assessment of the contributions of different flat roof types to achieving sustainable development.

This research was carried out to evaluate the effects of bentonite clay and wheat straw ash as a partial substitution for cement in SSC. Fresh characteristics were evaluated based on its passing ability and flowability using slump flow, slump T50, L-box, and V-funnel tests. After 7 days, 14 days, and 28 days of curing, cylinders of standard size were cast and tested for compressive and split tensile strength.
The test results indicate that bentonite clay and wheat straw ash decrease the passing ability and filling ability of SCC. Response surface methodology statistical models is used to optimize the combined dosage of wheat straw ash and bentonite clay and is verified through experimental tests. It can also be suggested that bentonite and wheat straw ash are successfully neutralized in concrete instead of cement. Recurring problems in the delivery of construction projects have been time and cost overruns, poor quality, poor health and safety, waste and loss of value.
This situation is worsened by the reluctance of construction organisations to This situation is worsened by the reluctance of construction organisations to fully implement lean construction technique which has proved to be an innovative solution to these problems. This study assessed construction professionals' perception of the awareness, adoption and benefits of lean construction in remedying poor construction project performance in the south-south region of Nigeria.
A well-structure questionnaire distributed by hand and electronically using the snowball sampling technique were used to gather data from the participants from both the private and public organisations. Frequency, percentage and factor analysis were used to analyse the collected data. It was found that the level of awareness of lean construction is high but it s adoption is low. Lean construction is a panacea for poor construction project performance because of it s cost related benefits, value and relationship benefits, environmental benefits, quality improvement benefits, motivation and productivity benefits, profitability and market benefits, time and work flow benefits, waste reduction benefits, and HS and rework reduction benefits.
