10 dez sustainable construction and sustainability background
Background on the goals The Sustainable Development Goals (SDGs) were born at the United Nations Conference on Sustainable Development in Rio de Janeiro in 2012. This has also led to an evolution of standards and criteria, particular schemes for assessing and certifying construction processes and products (Dickie and Howard, 2000). 8, November 2010. And that’s where sustainable construction comes in. The use of recycled aggregates for the partial replacement of natural aggregate also contributes to increase the sustainability of this type of product. It is broadly described as the judicious and equitable use of the world’s natural resources without compromising the needs of future generations (Dickie and Howard, 2000). Through the programme, all major sustainable construction activities can be brought together under the same umbrella. Another effective method is recycling, which besides minimizing the construction waste also reduces the requests for new resources, lessens the amount of energy for transportation and production, and use waste which would otherwise be lost to landfill sites (Pullen, 2013; Tam V. & Tam C., 2006). It can de defined as “the creation and responsible management of a healthy built environment based on resource efficient and … , define sustainability as meeting society’s present needs without compromising the ability of future generations to meet their own needs. Durability of concrete affects its service life highly. There is a waterproof membrane placed between the building and vegetation to support the vegetation as well as to discourage water leakage (Gaffin et al., 2009; Piro et al., 2017; Taylor, 2007). It is important to know that people working in green certified buildings were found to have a higher sleep quality, cognitive performance, and lower health symptoms as compared to conventional buildings (MacNaughton et al., 2017, 2016). The Earth has a finite number of resources, an growing population, and a need for sustainable construction. Specific actions have since been recommended, leading to increased legislation and regulation of sectors with the highest potential of contributing to the attainment of these objectives. With the above, a sustainable and acceptable IEQ can be achieved by employing passive procedures or techniques in construction such as using green roof in construction, employing natural ventilation method, fitting energy-efficient windows that are treated (e.g., window shading) to conserve heat in the cold and warm seasons by reducing heat loss and heat gain, respectively (Taleb, 2014; Wang et al., 2016). Carbon dioxide emissions are the main greenhouse gas emissions affecting the sustainable development. While the foundation of knowledge in this field is continuously expanding, sustainable construction is … Kibert (1994, 2013), Hussin et al. Sustainable construction mainly aims to reduce the negative environmental impacts generated by construction industry. Lafarge develops building solutions that are as forward-thinking as they are effective. Even though no concrete targets (on European level) are set yet, legal requirements on sustainable material use and on the environmental impact thresholds of new NZEB is expected in the near future. From Calkins, M., 2009. (2012) adaptive reuse is already widely applied in the United States, Australia, and across the Asia Pacific region for refunctioning facilities and buildings including important heritage monuments. Sustainable Development ties together concern for the carrying capacity of natural systems with the social challenges faced by humanity. this has progressed over the last four decades. If this regulation is passed, we will have a carbon and energy consumption limit for NZEB in Europe for the first time. A standard guideline proposal. This is because natural ventilation is difficult to adjust (ventilation rate mostly depends on outdoor airspeed and climatic condition) and ventilation is inversely related to temperature (Norbäck and Nordström, 2008; Toyinbo et al., 2016a). Mineral admixtures of concrete can play the most important role for this pursuit. From Calkins, M., 2009. Also, early integration of materials selection in the project planning stage is necessary. Transportation and Sustainability Best Practices Background ... definition states that sustainable development “meets the needs of the present without ... due to the lesser impact to natural resources and construction costs. As put by Tam and Tam (2006) “construction by its nature is not an environmental-friendly activity.” Nevertheless, it is quite clear that construction industry has to support a world of continuing population growth and economic development and cannot afford to apply a cradle-to-grave approach (where the raw materials are extracted, manufactured, used for a lifespan, and finally disposed). Over 90 classroom and online courses, including HQM & BREEAM assessor, starting from just £10. Furthermore, a new proposed design model involving NFC laminate for shear strengthening of reinforced concrete (RC) beams is also included in this chapter. USGBC currently boasts 77 chapters, over 13,000 member companies and organizations, and 188,000 professionals who hold LEED credentials. Forum 33, 209–224; Brabant P., 2010. France is one of the leading countries to set a new regulation seeking low carbon in nZEB and NZEB. Materials for Sustainable Sites: a Complete Guide to the Evaluation, Selection, and Use of Sustainable Construction Materials. Paulo R. Lopes Lima, ... Joaquim A.O. M.A. A. Hamood, J.M. Sustainability is sometimes termed the ‘triple Karl Desai, senior adviser for Advancing Net Zero at the UK Green Building Council, takes a look. A vernacular dwelling in old area of Mirbat town of Dhofar region in Sultanate of Oman has been selected as a case study to depict our integrated ICOMOS + C2C approach. A passive ventilation system (natural ventilation) for green building involves the opening of windows and doors for air circulation or the use of passive stack ventilation (PSV) system (Tong et al., 2017; Zhai et al., 2015). During construction projects, care must be taken to reduce waste and energy consumption where possible and protect the natural environment around the site. This helps to reduce carbon footprint that can affect the environment (Tong et al., 2016). The Sustainable Buildings and Construction Programme (SBC) aims at improving the knowledge of sustainable construction and to support and mainstream sustainable building solutions. The cement industry alone is estimated to be responsible for about 6–7% of all generated carbon dioxide. He considers that “Keeping buildings out of landfill dumps by not demolishing them is, ipso facto, an environmental benefit.”. The essence of sustainable construction would benefit from the inclusion of careful consideration of the healthiness of building materials. It doesn’t endorse or recommend any particular products or methodologies; instead, it aims to provide a basis for making informed decisions on how to make construction-related activities more sustainable. According to ASHRAE standard 55, 80% of building occupants should always be thermally comfortable (Olesen and Brager, 2004). With the high airtightness of NZEB and with the raised awareness of indoor air quality, the developments for the use of third party certificates, such as REACH, Green Screen, Health Product Declaration (HPD), are already in progress and in an advanced phase. Sustainability is avoiding the depletion of natural resources to maintain the ecological balance, and that’s what most businesses and industries mean when they talk about sustainability. Use minimal energy and generate minimum waste over the course of its lifecycle. For each ton of cement produced, nearly 1 ton of carbon dioxide is released into the atmosphere. So the concept of sustainable construction goes far beyond installing energy-efficient mechanical systems or making sure the client chooses LCD lighting for their new building. The certainty of global warming and, consequently, climate change urges for planners’ actions to create low carbon cities and, therefore, reduce the carbon emissions (Yung and Chan, 2012). This contributes to acid rains which affect ecosystems through a dry or wet deposition process. To achieve this, there is a need for a revolution in the manner in which construction is delivered and managed. There is approximately about 670 kg carbon dioxide per ton difference between emissions for PC and GGBFS. The tests carried out demonstrated these new elements have much higher load carrying and deflection performance than the ones of conventional ceramic filler blocks. Referring to Conejos et al. Experimental tests with prototypes of one-way prefabricated slabs with the new composite and ceramic filler blocks were also carried out to demonstrate the feasibility of the technology and the appropriate structural behavior of the proposed solution. In driving an innovation, awareness is fundamental. Sustainable construction, on the other hand, has no solitary definition that is accepted worldwide. He defines it as “a significant change to an existing building function when the former function has become obsolete.” Bullen and Love (2010) describe adaptive reuse as ‘‘a process that changes a disused or ineffective item into a new item that can be used for a different purpose” or a process that “involves converting a building to undertake a change of use required by new or existing owners” (Bullen and Love, 2011).

Research has shown that LEED buildings may have a slightly higher initial cost but offer savings over the life cycle of the building. As a sustainability specialist, you will identify ways to improve the sustainability of construction projects. In another study by Lu et al. The major durability problems in concrete include AAR, sulfate attack, steel corrosion, and freeze–thaw. Katie Thornburrow Cambridge City Council executive councillor for Planning Policy and Open Spaces The adopted 2018 Cambridge and South Cambridgeshire Local Plans contains a suite of policies setting out where and how new developments should be built in a sustainable and 46, 1133–1140; DETR, 2000; Dickie and Howard, 2000; Opoku and Ahmed, 2014, Potentialities of cement-based recycled materials reinforced with sisal fibers as a filler component of precast concrete slabs, Paulo R. Lopes Lima, ... Joaquim A.O. This is because air recirculation is sometimes done in mechanically ventilated buildings by blocking outdoor air in order to quickly achieve indoor air conditioning and save energy (Joshi, 2008). This video was first broadcast at CN Decarbonising Construction 2020. As part of its certification, evaluations of 11 groups of building materials and components are undertaken (floor coverings and suspended ceilings from timber, other timber materials, doors, sockets, paint, parquet overcoat, sealing materials, body filler, tile adhesive, gypsum boards, plaster, concrete parts, and movable dividing walls).
