Civil Engineering Environmental Impact & Benefits To The Economy (2024)

Civil Engineering Environmental Impact: Civil engineers can contribute to the growing global concern over the environment. Lagan Construction Group, a global civil engineering and construction company, provides essential environmental considerations for civil engineers. Since the need for infrastructure is expected to increase shortly, civil engineers have the power to make significant changes that will reduce carbon emissions.

There can be no doubt that this necessitates a radical shift in sustainable thinking and quick action.Civil engineerscan make a few environmental considerations to lessen the environmental impact of construction.

Enhance Energy Efficiency

Energy is heavily used in the construction sector. Building and construction alone account for 40% of all energy consumption in the U.S. The U.S. Department of Energy has provided statistics that support this.

• The entire building cycle, including the extraction of construction materials, transportation of those materials, use of equipment and tool installations, and even disposal of waste materials, requires energy. Since there is so much energy, it accounts for almost 6% of construction costs.
• Although it is nearly impossible to know how much energy will be used throughout the construction process cycle, everycivilengineermust prioritize energy efficiency in every stage of construction, especially when using non-renewable energy sources like oil and gas.

Among the wayscivil engineerscan cut back on energy use or waste during the building process are as follows:

1. It was updating machinery and equipment and fixing it as soon as it broke. Using outdated, worn-out, or damaged tools and equipment takes much more energy and slows down building projects. Energy consumption increases with the speed of construction.
2. They are building houses that use less energy.
3. Employing construction methods and designs that use less energy.
4. Utilize construction vehicles and heavy machinery that are energy-efficient and are built to perform well while using less energy. Using a wheeled excavator instead of a tracked one, for instance, since they are more fuel-efficient
5. installing H.V. systems, lighting fixtures, and other utilities that use less energy.
6. Retro-commissioning of the structures to enhance system performance and effectiveness.
7. We are utilizing and putting in place renewable energy sources.

Constructing Less Waste

The construction sector is responsible for 50% of landfill waste. This makes it clear that proper planning, resource tracking, and monitoring are required to reduce waste. These wastes cause faster resource depletion and environmental damage.

• Civil engineers have many options for reducing construction waste and, consequently, the amount of debris disposed of in landfills. Before any construction work starts, ensure an adequate waste management plan has been created.
• Second, think about establishing waste reduction objectives that all parties can meet. Finding ways to maximize the use of a few of the materials as well as recycle and reuse the construction equipment

Other methods comprise:

1. We are minimizing the scrap pile on construction sites through careful planning. Everything needs to be accurately measured, cut out, and ordered in the proper quantities and sizes.
2. Keeping materials safely stored will prevent the need to replace lost or stolen items.
3. Utilizing durable materials and alternative building techniques to promote recycling and reuse. For instance, instead of using plywood or lumber for the formwork, you can use modular metal form processes that can be reused.
4. Select eco-friendly or minimally packaged products to reduce the waste you produce and need to dispose of.
5. Obtain construction supplies from vendors who recognize returns or pay for unused materials.

Green Materials Utilization

Sustainable constructionentails incorporating eco-friendly materials into all phases of the building process, including design, material extraction, construction, and operation. Green materials are made of renewable resources whose long-term effects on the environment have been carefully considered.

• Given that the cost of materials is rising daily and these materials are not only cost-effective but also environmentally friendly, civil engineers may consider going green. Green materials aid in energy conservation. They lessen the costs associated with building maintenance and the adverse effects of construction on the environment up until the point of disposal.
• Green building materials will significantly lower the nearly 3 billion metric tons of raw materials that the global building and construction industry consumes annually.
• Bamboo trees, rammed earth, straw bells, reclaimed steel, recyclable plastic, precast slab concrete, reclaimed wood, hempcrete, and others are environmentally friendly building materials that can be used for residential and commercial structures.

Almost Energy-zero Buildings

A more recent term is nearly zero-energy buildings (NZEBs). Fortunately, the idea spread quickly. The idea was developed in Europe and just recently made its way to the American construction industry, and it appears to have been around for a while.

• An advanced idea known as “nearly zero” basically states that buildings should be planned and constructed with low energy costs close to matching the site’s renewable energy production. As a result, the structure will have a lower carbon footprint than a conventional structure.
• The construction industry significantly contributes to soil, water, and air pollution. These pollutants can pose a significant threat to the environment, and if the appropriate controls and mitigation strategies are not implemented, adverse environmental effects may result. Civil engineerscan plan and build more environmentally friendly buildings without adding to the already high levels of pollution. These things will contribute to a cleaner environment and a better future.

Buildings Significantly Impact Climate Change

More than 40% of the energy we use worldwide and a third of the greenhouse gas emissions come from our buildings. Both developed and developing parts of the world can attest to this.

Most of these emissions are caused by the buildings’ ongoing use of electricity, lighting, heating, and cooling. Buildings also produce some non-CO2 emissions, such as halocarbons. In the past, developed countries accounted for the majority of emissions.

Still, developing nations are quickly catching up, and it is anticipated that emissions from buildings in recently emerging countries will soon surpass those from developed countries.

Governments Can Also Assist

Governments have a responsibility to ensure that new construction considers the future. They must prioritize the construction and civil engineering industries in their climate change policies and plans. Each nation’s government can support the construction industry by establishing reliable, attainable, and measurable energy performance standards and objectives.

Additionally, training needs to be offered so that some skilled workers and adjudicators can evaluate the energy efficiency of buildings and guarantee that all techniques and technologies are being used. Education is essential in getting the building industry involved and motivated to meet emissions targets.

Civil Engineering Benefits to the Economy

Reduced emissions from buildings are beneficial to the economy and its inhabitants. Globally, the building, renovation, and maintenance of commercial and residential structures account for approximately 25% of a country’s GDP and employ approximately 10% of the workforce.

There is a massive opportunity for new employment and companies to serve these drives and development objectives by increasing the quantity of measures to make buildings greener.

Conclusion

Despite making great strides in recent years to reduce carbon emissions, the construction industry still has a significant negative impact on the environment. Buildings are thought to be responsible for close to 40% of CO2 emissions.

This accounts for over a third of all emissions worldwide. Building operations make up 28% of these, with construction materials and buildings making up the remainder. The primary sources of these emissions are lighting, heating, cooling, and electricity, with most of the remaining emissions coming from the three most common building materials—steel, concrete, and aluminum.

Civil engineers must work to reduce all emissions so that the pre-industrial level limit of 2°C (or ideally a 1.5°C target) is met by 2040 to meet the net-zero target set forth by the International Energy Agency (IEA). If we want to reach net zero by 2050, that means a 6% annual decline. You should be able to understand the most crucial environmental factors for civil engineers after reading this article.
