Early Planning Can Reduce Environmental Impact in Construction Projects

Early planning ensures compliance with ever-stricter environmental regulations. It allows time for devising the most efficient building processes, reduces waste generation and minimizes a project’s overall carbon footprint. Any construction project can become more sustainable and cost-effective with strategic early planning. 

The Construction Industry, Total Greenhouse Gas Emissions and Waste

According to the United Nations, the construction industry is the largest emitter of global greenhouse gases, adding 37 percent to the total from the production and use of steel, cement and aluminum. The pollution comes from several sources, including:

• The fossil fuels used in converting raw materials to usable products and delivering them to the job site
• The emissions created from fossil fuel burning on job sites from various equipment 
• The waste created, which ends up in landfills and contributes to methane release, a greenhouse gas heavier than carbon dioxide 

A glance at this list reveals the importance of early planning in reducing a construction project’s environmental impact. The most immediate savings come from reduced waste, which also keeps more money in your firm’s pocket. However, you also save the emissions created when delivering unnecessary goods to the job site. Sufficient early planning at all levels also keeps raw materials in the ground until needed. 

Sustainability in Construction: A Delicate Balancing Act 

While it may seem like reducing the environmental impact of construction projects through early planning is a simple, straightforward practice, it entails a delicate balancing act. Reality dictates that you must work within the scope of the resources available, which can add a twist to your processes as you strive to save money and improve sustainability. 

For example, your ultimate goal might be a net-zero design — a building that produces sufficient energy from renewable sources to meet its needs without drawing from the grid. However, relatively few of these structures exist because of how new the concept is and the current cost prohibitions on certain materials. 

Do you think solar panels will do the work? They aren’t sufficient alone. You must pair them with energy-efficient building designs and materials to maximize efficiency. For example, a plan lacking adequate insulation can bleed power through its walls. Choosing the right doors, windows and insulating materials keeps extreme outdoor temperatures and wind from affecting the indoor environment much, minimizing heating and cooling needs. 

Such tradeoffs matter, especially in places that don’t see much sunlight — another consideration in the early planning stages. Buildings in extreme northern or southern latitudes might benefit more from geothermal heat pumps, using the heat stored within the earth to run the HVAC system. 

Sustainability in construction is a delicate balancing act that requires sufficient early planning in these core areas: 

• Water use: What’s the nearest available water source? How feasible is it to use rainwater collection for irrigation purposes? If this commodity is scarce in the region, is it cost-effective to include an on-site gray water treatment facility for recycling it or rely on standard systems? 

• Energy production: Does the region get sufficient sunlight to make independent solar power feasible? If not, is another sustainable energy source available? 

• Building orientation: Does the building’s layout allow for maximum use of passive solar for heating, cooling and lighting? If not, how can you alter the design to take advantage of what nature provides? 

• Appliances and fixtures: What are the most energy-efficient options you have within your budget? For example, an Energy Star-rated HVAC system reduces fuel use even if the building doesn’t rely on renewable energy sources. Low-flow toilets and faucets minimize water needs, as do washers and dishwashers that keep H₂0 demands low. 

• Insulation: Which materials are readily available and sustainably sourced? If they aren’t sustainably sourced, like straw bales, are they readily recyclable? For example, while you can recycle the polystyrene in many commercial insulation brands, it isn’t cost-effective, meaning it usually ends up in landfills. 

It’s equally vital to keep up with the latest research and development to make the best choices in the early planning stages of a construction project. For example, a new method of recycling polystyrene produces a material that markets for 10 times more, creating an economic incentive to build sufficient infrastructure. If widely adopted, this material will become a more sustainable choice. 

Questions to Ask Yourself During the Early Planning Stage

Asking yourself the following questions during your project’s early planning stages smooths the decision-making process and gives you greater confidence that your project treads lightly on the planet. It also reassures you that you’ve maximized cost-effectiveness. 

1. What Is the Scope and Planned Use of Your Project? 

What are the site and size requirements? Do those funding the project foresee the need for future additions? What vibe do they want people to feel when coming into the space? How much time and leeway do you have? For example, a creative arts building might embrace repurposed materials, coveting them for adding charm. 

Consider drafting a preconstruction checklist that determines a timeline for the scope of your project, as well as potential plans. Having all your details in order before beginning action items ensures all finances and materials are put to good use.  

2. What Is Your Budget? 

You must ask this question in every project, as it will entail tradeoffs. For example, mineral wool is one of the most sustainably sourced insulation materials, but it’s expensive. Although you can generally save money by choosing batt-style insulation over blown-in, that dynamic may change if you already possess the necessary equipment. Sustainability means making the best choices with the resources available, which necessitates knowing what each option costs.

3. What Materials Will You Use? What Is Their Source? How Reusable Are They?

Remember, choosing the most sustainable materials means considering their entire life cycle, from raw materials to building demolition. For example, hemp, bamboo and cork readily regrow and don’t require heavy deforestation to harvest and use. Although steel takes considerable energy to forge, it’s nearly infinitely recyclable without losing structural integrity. Many plastics take relatively little energy to produce but can only withstand one or two recycling cycles. 

Environmental Regulations and Construction Project Planning 

Early planning is crucial for avoiding environmental regulation violations that can cost a small fortune to remedy and further bury your organization with fines. For example, the Biden administration recently announced changes to the Clean Water Act and Endangered Species Act and updated rules for chemical use. 

Precise rules vary by jurisdiction. Many construction companies hire environmental consultants to keep them abreast of changes in regulations, as a pound of prevention is far more cost-effective than the cure. Additionally, building things that violate the standard creates more environmental devastation when you must tear down and replace materials. 

Even working in a green industry doesn’t provide immunity from oversight. For example, Swinerton, a U.S. construction firm that builds solar farms across the country, recently agreed to pay $2.3 million in penalties for alleged Clean Water Act violations. Early planning matters no matter your niche.  

Reducing the Environmental Impact of Construction Projects Through Strategic Early Planning 

The construction sector generates a considerable environmental impact from manufacturing raw materials into goods to transport, installation and eventual demolition. Solving the climate crisis means firms must proactively reduce their footprints, beginning with early planning. 

Strategic early planning maximizes energy efficiency in building design while minimizing material use and waste. Taking your time to find the most sustainable approach also keeps money in your pocket, so going green pays off.
