The LCA method evaluates the environmental aspects of a product system at all phases of its life cycle [2].In the construction sector, LCA assesses the impact of a building on the environment in all phases including material manufacturing, material transportation, construction, operation and maintenance, demolition, and construction waste disposal.
This paper outlines a methodology for structuring a generic database of environmental impacts on the end-of-life phase of buildings, which can be used at the national level, in accordance with European standards. A number of different options are also considered for managing construction and demolition waste (CDW), as well as for promoting the circularity …

Life-cycle Cost = I + PV RECURRING COSTS (operations, maintenance, energy, repair, renovation, etc.) + PV DISPOSAL COST – PV Residual Value. In most cases it helpful to separate the building/structure into major systems and run life-cycle costs individually bases upon materials and equipment used.
In last decade, the building life cycle emissions and energy efficiency have been researched widely. Most of the studies focus on the assessment models and emission analysis based on the available ...
The end-of-life of buildings is increasingly involved to improve waste management and environmental concern of the construction sector. A Life Cycle Assessment (LCA) model is suggested in this paper to holistically estimate environmental impacts of the end-of-life of any building. ... Waste transport and waste disposal are of the same order of ...

To accomplish the goal, a rigorous LCA methodology is employed, encompassing the various stages of the building material life cycle, from extraction and manufacturing to transport and eventual disposal. This paper …
Architects are increasingly interested in reducing the environmental impact of the buildings they design. Life Cycle Assessment (LCA) helps answer questions that arise during the design and construction of a green building since it provides scientific justification. ... use, and disposal. This method informs property developers on the cost of ...
The quest for sustainable buildings must also consider the disposal of building materials, describe the new concepts of the life cycle of building materials and secondary use of building components, and assess the recyclability potential of these materials (Vefago and Avellaneda, 2013).
We say 'design for long life, loose fit'. By designing for long life and end-of-life scenarios responsibly, wood is uniquely suited to disassemble. By using loose bolts, pins, and screws, …

But losing space to required systems means giving up rentable square footage, Cross said. That ...
88 demolition offers a fast way of building disposal, its environmental and economic impacts are 89 overwhelming. However, a more sustainable approach to the end-of-life disposal of buildings 90 is building deconstruction, which is the disassembly of buildings piece by piece to maximise 91 material reuse (Kibert, 2008).

Although demolition offers a fast way of building disposal, its environmental and economic impacts are overwhelming. However, a more sustainable approach to the end-of-life disposal of buildings is building deconstruction, which is the …
Life Cycle Cost Analysis (LCCA) is a form of economic evaluation that compares the costs and savings of alternative building designs and systems over the life cycle of a building. Green building features generally have higher initial costs compared to conventional features but offer operational savings over time through decreased resource use ...
products in many fields of human activity, and, specifically, in building materials industry. When life-cycle data is available, there appears an opportunity to make relevant changes in the way of extraction, manufacturing, installation and maintenance of products, and, in the end, disposal, recycling or reuse.
The traditional methods of building disposal require the dismantling and knocking down of buildings using crushing force using bulldozers, wrecking ball, explosives, etc. …

The process of recycling waste material to be made into new products, materials, or substances has become highly important in the construction industry. Glass could be a highly reusable and recyclable material, but is rarely utilized to formulate new glass products.
The built environment is one of the main causes of environmental impacts in Europe [1].The construction, use and renovation activities require significant amounts of energy (about 40 % of the consumed energy) and mineral resources [2].These represent a major source of pollution and consequent noteworthy adverse impacts on the environment, which normally include dust …
end-of-life building disposal to modern methods such as decon-struction. This is because design capabilities on reducing end-of-life impacts of building activities are limited in traditional methods of building disposal such as demolition and landfilling. It has also been argued that deconstruction, which is the disassembly of
Firstly, LCA allows for a thorough evaluation of the environmental impacts associated with construction materials. By considering the entire life cycle of these materials, from extraction to disposal, LCA provides a comprehensive understanding of their environmental footprint [107], [109], [185].This insight enables decision-makers to identify the most significant …
