The Construction Industry Is Getting Greener: Why, How, And What’s Changing?
Environmental sustainability and the energy-intensive construction industry don’t often go hand-in-hand. The construction industry is a massive consumer of raw materials and natural resources, and it generates an estimated 39% of the world’s carbon emissions according to the World Green Building Council.
However, there is some good news. The sector is gradually becoming more sustainable despite many conflicting goals and complex challenges.
In a recent global survey across multiple sectors, we have seen that executives in the engineering and construction industries have made the most progress toward sustainability in the design phase, where 47% of respondents said sustainability is top-of-mind or a major concern.
Sustainable design will be critical as construction companies seek to reduce their energy consumption in completed buildings. However, the survey also revealed that executives are more likely to have set sustainability goals rather than to have taken concrete action to achieve those goals, according to the survey of 1,000 respondents from industries globally.
Sustainability: A Complex Issue for Construction Companies
Sustainability is just one aspect of the deeply complex construction industry that grapples with increasingly stringent regulations on health and safety and sustainability.
Engineering and construction leaders face a number of competing pressures as they try to control costs and maintain efficient processes with multiple suppliers and subcontractors, and also focus on reducing energy costs and carbon footprint while using energy-intensive heavy equipment.
All of this is on top of trying to develop structures that are scalable, taller, greener, healthier and more technologically advanced than ever before.
The industry recognizes the need to address these urgent and often competing issues, especially within their supply chains. According to the survey, 59% said a sustainable supply chain is a competitive differentiator, but 47% said increased process complexity is an obstacle to meeting their sustainability goals.
Managing the complexity of construction projects is challenging throughout the lifecycle starting right from when a company is awarded a project, through to hiring the right people, getting the right materials, supplies, and equipment to the site, and building the structure to completion on time. Then there is ongoing operation and maintenance of the finished project. Trying to incorporate sustainable practices into all of these areas is an escalating challenge.
Three Factors Influencing Sustainable Change
- Increasing government regulations: New regulations, such as the Construction Products Regulation (CPR) and the European Green Deal, are demanding increased environmental measures, which place more scrutiny on how projects are designed, constructed, and maintained. The United Nations has announced several ambitious targets for sustainability in construction. For example, the target reduction rate for energy intensity per square meter in buildings will be approximately 30% by 2030, as defined by the Paris Agreement. Increased regulations are pushing engineering and construction companies to look for more circular and sustainable solutions.
- Controlling costs: Cost-efficiency is still a key consideration for most engineering and construction companies. As the cost of raw materials continues to climb, business leaders need to plan and manage construction projects using the most cost-effective products and raw materials possible, while ensuring workers and heavy machinery are not sitting idle. If sustainable materials or processes are too expensive, decision-makers may choose not to use them. In the survey, half of the engineering and construction respondents said lowering the cost of sustainable products would make the biggest difference in helping them meet their sustainability goals. On the other hand, reducing the high cost of energy consumption will lower costs while also improving sustainability efforts for this energy-intensive industry.
- Expanding environmental concerns: A growing number of customers and owners are pressuring engineering and construction companies to design and build more eco-friendly structures. As demand for environmental considerations builds, a growing number of investors, and even employees are questioning traditional construction methods and pushing for more sustainable business practices.
The Biggest Challenge: A Lack of Visibility
While many engineering and construction companies have made sustainability plans and commitments, the survey shows that few have taken concrete steps to realize their sustainability goals. That’s because a lack of visibility is a major issue when it comes to monitoring sustainable practices in their own processes as well as with their subcontractors and supply chains.
For instance, when it comes to sustainable sourcing of required raw materials, just over half (55%) of engineering and construction companies have significant or complete visibility into their own processes, and only 16% have the same visibility into their suppliers’ processes.
And when it comes to the ethical sourcing of necessary labor, only 50% have significant or complete visibility into their own processes, and just 17% have the same level of visibility into their suppliers’ labor-related processes.
There are some areas, however, where the construction industry is making progress. For example, 58% of engineering and construction firms said they have reduced overall energy consumption, and some innovative companies are developing sustainable building materials that release lower carbon emissions and actually absorb carbon dioxide and heat from the environment.
Sustainability By Design
Architects and engineers are designing more energy-efficient buildings with the help of technology, and that is putting increasing pressure on construction companies to digitize. For example, Honeywell are transforming how buildings are managed and Costain has invested in solutions that will help to create more sustainable and cost-effective infrastructure management.
Even though the industry may lag behind other industries when it comes to adopting sustainable practices, engineering and construction companies are actually more advanced than many other industries when it comes to using technology during the design process by using digital twins and Building Information Modelling (BIM).
More than half (51%) of engineering and construction respondents use mobile technology during the design phase, and 37% use mobile in maintenance processes. Many respondents (46%) said this results in increased visibility into suppliers, which is a vitally important aspect of sustainability. More than half (55%) also use 3D printing in the manufacturing process, and 51% reported increased visibility from their use of 3D printing as well.
How the Construction Industry Can Become More Sustainable
- Create a long-term strategy that considers sustainability in every process from start to finish.
- Source materials ethically and ensure labor standards and fair humanitarian practices are in place with all subcontractors and suppliers.
- Implement sustainable design, engineering, and construction practices powered by relevant data to track, measure, and reduce emissions and waste throughout the project lifecycle.
- Use logistics processes that optimize deliveries to reduce mileage, emissions, and carbon footprint.
- Operate assets and equipment in an energy-efficient manner that is safe for the environment and for the workforce.
A Sustainable Future is Good for Business And For Our Planet
As more executives realize that sustainable choices are actually good for business, more engineering and construction companies will set sustainability commitments and adopt sustainable practices into more aspects of their business. Now is the time to take action to balance the bottom line with the green line in the engineering and construction industry.
