Construction and construction practices and their effects on the environment
Construction involves the planning, design, and building of structures. It begins with planning and design then continues until the structure is ready for occupancy. There are nine main types of construction including residential, commercial, multi-family, healthcare, industrial, institutional, and heavy civil construction. New construction techniques focus on sustainability, efficiency, and reducing waste through advances like 3D printing and new materials and building methods. Construction impacts the environment through consuming resources and creating pollutants, but sustainable approaches aim to reduce this impact.
Sustainable Construction
Sustainable construction focuses on reducing environmental impact through techniques like using low-VOC paints and formaldehyde-free plywood. It also aims to integrate energy and water efficiency into building design and operations. The key principles are to reduce consumption, reuse materials, and recycle where possible. Sustainable construction evaluates projects based on innovation, social inclusion, environmental performance, economic viability, and contextual design impact. Corporate responsibility is also important, with considerations for minimizing impacts on the environment, fair treatment of workers, community engagement, and ethical business practices.

Construction and Demolition Waste Recycling
This document summarizes a presentation on construction and demolition waste recycling and provides legislative comparisons from Denmark, Hong Kong, and Queensland. It finds that Queensland is recycling only 42% of construction waste, compared to over 90% in Denmark and other countries. The presentation recommends that Queensland implement policies like landfill levies, recycling bans, and mandates for source separation to increase recycling rates as done successfully in other regions.
Sustainability in Construction Sector
This document discusses sustainability in the construction sector. It begins by defining sustainability and its three pillars - environmental, economic, and social. It then discusses sustainability at various scales from global to local. Sustainable development strategies aim to balance these three pillars through principles like respecting environmental limits and improving quality of life. The construction sector has significant environmental impacts through resource use and pollution, but can also support economic and social sustainability through jobs and infrastructure. Sustainable construction approaches like green building aim to minimize these environmental impacts over the full building lifecycle from construction to demolition.

Adoption of Green Building Practice in Commercial Properties in Lagos, Nigeria
Buildings account for a sizeable amount of total
energy consumption and total greenhouse gas emissions
around the world. Green building has consequently emerged
as innovative building concept to lessen the environmental
impact of these buildings. This survey-based study therefore,
evaluates stakeholder’s perception of possible adoption of
green building practices and application in commercial
properties in Lagos, Nigeria. The survey was conducted in
Lagos, using a random and purposive sampling technique
with a well-structured questionnaire to gather data from175
respondent comprising 52 property developers and
123Registered Estate Surveyors and Valuers. Data collected
was analyzed using descriptive and inferential statistics with
the aid of SPSS. The result of the findings revealed that
respondents have a low level awareness of green building in
general. The study further reveal that green features that
would be mostly adopted by stakeholders include: careful
orientation and low-energy lighting design, the use of
renewable energy e.g maximum use of natural day lightening
and the use of energy efficient and eco-friendly equipment.
The study advocated for increased sensitization of benefits of
green building among built environment practitioner. By so
doing it will deepen the adoption of green building practice in
the study area. The study recommends widespread supply of
green features in commercial properties. Also Professional
bodies should train and educate their members on the
importance of green so as to incorporate the lofty practice in
their daily practices. Overall, public enlightenment,
awareness, and better enabling green building practice can be
improved in Nigeria.
Sustainable Development of Green Building on Design Efficiency
Green building aims to reduce environmental impact through sustainable design, construction, and operation. The design stage significantly impacts costs and performance by minimizing total environmental impact over the building's lifecycle. Benefits include reduced operating costs, improved occupant health and productivity, and protection of biodiversity. However, implementing green building faces challenges like lack of government incentives, low public awareness, and high initial costs. Suggestions are provided to address issues like poor maintenance, unsuitable locations, and unqualified architects.
The shaping of new sustainable housing concepts

Solid Waste Management
This document discusses solid waste management and identifies three basic approaches: source reduction, recycling, and composting. It defines solid waste and describes source reduction as changing products/packaging to reduce amount/toxicity of waste before it becomes solid waste. Recycling recovers materials like paper, plastic and metal from trash to make new products. Composting involves collecting organic waste and storing it to naturally break down into fertilizer. The most sustainable approach is source reduction as it saves resources and reduces toxicity.
Sustainable building designs
This document discusses sustainable building design, policy, legislation, and environmental building assessments. It provides an overview of key concepts in green building and sustainable construction, including the importance of material selection and addressing environmental, performance, and cost implications. The document also outlines the development of policies and legislation related to sustainability in both the UK and Malaysia, and discusses various tools for assessing the environmental performance of buildings, including BREEAM, LEED, and the Green Building Index.
A Theoretical Study on Green Concrete Construction
Concrete which are taken from the demolished structures or from concrete waste which are considered to be eco friendly and using it for the purpose of another building construction is called as green concrete construction. This helps to make the future construction eco friendly and also reduce the emission of CO2. Now a days global warming is the major drawback of whole world which is directly or indirectly caused by the civil engineering field. The world consumes concrete more next to water. So it is the duty of every civil engineer to go along the disadvantages of green house gas emission and to reduce their effects in environment. This can be sought by using the eco friendly materials and also the eco friendly waste concrete available in earth. This journal paper would provide the ideas of green construction and also helps to induce the engineers choice of construction.

Incorporating construction and demolition waste in walling technologies for s...
Waste management and slum formation are two major problems worldwide; they can be seen as interrelated problems in the sense that the more slums are formed, the more wastes are accumulated which raises the bar for reaching a solution to urbanization and waste management problems. Hence, the products of construction waste recycling can be the stimulating factor for slum upgrading which will give dual benefits to the city.
130 waste management
The document discusses waste management practices for construction sites. It outlines the waste management hierarchy of reduce, reuse, recycle, recover, disposal. It emphasizes identifying and separating waste streams. Regulations require a waste management plan and proper handling, transport, and disposal of waste, including hazardous waste. Good practices include designating a waste manager, separating waste, and using prefabricated materials to reduce waste. Metrics like the BRE SMARTWaste tool can benchmark waste.
Mechanical Properties of Recycled Aggregate
This document discusses the use of recycled aggregates in concrete. It begins by outlining the large amounts of construction waste produced annually in India and globally, and the environmental benefits of using recycled aggregates to reduce dumping. It then reviews the mechanical properties of recycled aggregates compared to natural aggregates, finding generally lower compressive strength but also improved drying shrinkage and porosity. The methodology section describes testing recycled concrete collected from demolition sites. The expected findings are that recycled aggregates can partially substitute for natural aggregates in building applications while saving costs on transportation and reducing environmental impacts. References are provided on the topic of recycled aggregate use.
Construction & Demolition Waste
Construction industry is one of the biggest sector in India with increasing demand. We need to take certain actions and precautions on site to reduce construction waste. Metro cities like Pune, Mumbai and Bangalore etc. are most congested cities. So, the need of flats, apartments, row houses etc. is increasing with higher rate. We need to demolish the existing old structures and build new structures to have the maximum space for environmental purpose. So, there is increasing in demolition waste as compared with construction waste.
There should be certain provisions for the checking of this waste management cycle to prevent its impact on environment. Construction and demolition waste can be classified into 2 components; major components include cement concrete, bricks, cement plaster, steel from RCC, doors & windows, roofing support systems, rubble, stones, timber etc. and minor components includes conduits, GI pipes/Iron pipes/Plastic pipes, electrical fixtures, panels, glass etc.

Green
Green manufacturing aims to make products and processes safer for the environment and human health by using less toxic materials, recycled content, locally sourced materials, and renewable energy. Deconstruction is the careful dismantling of buildings to maximize reuse and recycling of materials while minimizing landfill waste. Reuse programs redistribute still-usable goods and materials from demolition to further reduce waste and preserve embodied energy from original manufacturing. Together, these practices help promote sustainability across manufacturing, construction, and waste management.

Reuse programs redistribute still-usable items and materials from demolition to keep them out of the waste stream and reduce the need for new production.
Building materials and environmental impact
building materials have considerable impact on environment. so choosing the right material and knowledge about modern materials is equally important in modern day construction and technology
Construction and Demolition Waste as a Resource
This document discusses construction and demolition (C&D) waste in India. It notes that C&D waste makes up a large portion of India's solid waste and estimates that 165-175 million tonnes of C&D waste are generated per year. It discusses government initiatives to increase recycling and use of recycled C&D waste in construction. These include guidelines from agencies like CPWD and BMTPC, as well as the C&D Waste Management Rules of 2016 which require segregation and processing of C&D waste. The document advocates increasing recycling and reuse of C&D waste to reduce impacts on landfills and natural resource extraction.
HRP FINAL PIECE
This document summarizes a research journal on whether building conservation policy in England has gone too far in restricting the beneficial reuse of buildings in urban areas. It begins with an introduction noting the rise of listed buildings and conservation areas creating a paradox between protective legislation and demands of urban growth. A literature review found that while building conservation is important for preserving history, current policies may restrict efficient land usage and development opportunities. Interviews with industry professionals aimed to discuss current thinking on these issues and how policy could be adapted to allow more efficient redevelopment while still protecting heritage assets.

Appropriate technology part 1
- There is a need for alternative and appropriate technologies in construction due to the large housing shortage and constraints on materials and resources. Labor-based construction programs using local materials can help address this need.
- Appropriate technologies should follow principles like energy conservation, using local and renewable materials, and minimizing environmental impact. Waste materials from industries can be used to make building materials.
- Low-cost and appropriate technologies do not compromise on quality or strength while using less capital and resources. They are developed based on local needs and capabilities.
- Research institutions are developing appropriate technologies like stabilized mud blocks, mud plasters, and vaulted roofs that utilize local materials and labor to lower costs.

Green architecture aims to reduce negative impacts on the climate, health, and environment through resource efficient and low emission building designs. It can save money over the lifetime of a building. Some challenges of green architecture include the high initial costs of sustainable materials and technologies like solar panels. Historically, architects like Frank Lloyd Wright designed buildings to work with nature instead of dominate it. In the 1970s-1980s, green architecture emerged focusing on natural materials and reducing pollution. Benefits include cost savings on utility bills. Locally sourced materials also help the local economy and reduce emissions from transportation.
Wicked problems, Gayle De Bruyn
The document discusses strategies for applying design thinking and circular economy principles to challenges in the building industry. It highlights wicked problems, introduces concepts like design thinking and circular economy, and provides examples of organizations applying these approaches. Specific initiatives mentioned include efforts to recycle materials like fishing nets, cigarette butts, and construction debris. The role of standards, pre-design, and considering whole lifecycles are also discussed as important to transitioning to more sustainable and circular building practices.
New Forms of Shared Value Resulting from Valuing Natural Capital as Business ...
Dow Chemical has established 2025 sustainability goals that include valuing nature through business decisions. Their goal is to deliver $1 billion in business and natural capital value through projects that benefit both. By 2020, Dow will screen all projects using a Nature's Future Value tool developed with The Nature Conservancy to measure ecosystem services. Examples of past projects include constructed wetlands that saved over $48 million by providing wastewater treatment for $1.4 million, and land conservation that protects natural areas and wildlife habitats while reducing costs. Moving forward, Dow will quantify projects' impacts on nature using this tool to identify ecosystem services and measure their value in engineering terms to evaluate project cost-effectiveness.
