The ultimate guide to reducing construction’s environmental impacts
Deepen your understanding of how to improve sustainability throughout project lifecycles using building and construction technologies.
Construction stakeholders, from owners to contractors, are under pressure to reduce construction’s environmental impact. Material selection and design innovation are essential but not enough on their own. To build a greener future, we must embrace a holistic sustainability approach to minimizing inefficiencies, rework, and waste through every project phase. These three approaches from The Ultimate Guide to Sustainable Construction Technology will help you improve communication across construction teams and choose the building technology that's right for you.
A connected outlook
An estimated 20% of construction materials go to waste. How can we transform workflows to reduce emissions and unnecessary consumption? By providing essential tech and interconnectivity to teams, a connected construction approach gives the right people the right data at the right time, reducing rework and errors.
Your strategic priorities, budget, team capabilities, and client/user expectations all play a role in determining which tech you adopt. Only invest in new resources that enhance your current abilities and make processes more efficient. Here are the good, better, and best tools in the market and how each contributes to improvements in sustainability.

1. A good start
While reducing construction’s environmental impact is mission critical, you must begin with a solid foundation of essential tools. Otherwise, you may be overpowered by tech instead of empowered by it. These three tools will help close gaps between siloed construction teams, setting the groundwork for better communication, workflow management, and decision-making.

3D modeling software
Use 3D modeling software to iterate and spot conflicts early on in the project quickly. From estimating to earthmoving, import point cloud data in modeling software to support accurate and efficient workflows. Share easy-to-digest data across teams and throughout the project lifecycle.
Common data environment (CDE)
Access data across stakeholders, log tasks, and document project details into a cloud-based system — your single source of truth. We recommend you follow these best practices to make the most of your CDE.
- Give the right people the right access at the right time
- Support the need for individual CDEs
- Look for one-to-one data mapping
- Automate workflows using APIs
- Capture only the data you need
- Leverage open sharing standards
- Work from a single continuous model
Project management system
Project management systems give construction teams significant control over the risks that commonly lead to waste and inefficiencies. Automated project updates, approvals, and alerts minimize friction between stakeholders. A sound management system provides real-time numbers to evaluate project performance strategies and empowers teams to predict the impact of change orders.
The construction ecosystem is responsible for 25% of global greenhouse emissions, 600 million tons of yearly waste, and 14.5% of particulate matter in big cities.

2. Getting better
Once your foundational systems are in place, adopt technologies that leverage centralized project data to perform more sophisticated tasks. These collaborative platforms give stakeholders the right data to make better decisions faster.
Building information modeling (BIM) tools
Connect multidisciplinary teams from pre-construction through operations and maintenance. BIM software offers automated clash detection and supports accurate performance measurements for sustainability goals.
Feasibility planning software
Combine environmental, community, cultural, engineering, and cost factors into a single analysis with feasibility planning software — your civil engineers will thank you. They can use this tech to inform engineering decisions and share environmental considerations with key stakeholders.
Extended reality technologies
Simulate sustainable design strategies with realistic detail. Extended reality tools use mixed and augmented reality to visualize models in real-world environments. They reduce errors and rework, including showing where critical systems are behind walls before drilling begins.

Building performance analysis & environmental modeling software
Use this software to understand how your building performance measures up against building code baselines, climate change objectives, and sustainability certifications. Perform early assessments of energy needs and capabilities with pre-design performance insights.
Machine control systems
Correcting earthwork failures is exceptionally resource-intensive. Getting it right the first time reduces material use and fuel consumption. Use 2D drawings and 3D models, along with global positioning systems (GPS), to position equipment accurately. If you don’t want to purchase new equipment, you can outfit existing equipment with machine control technology.

Positioning technologies offer broad sustainability gains in both building renovations and new infrastructure projects. Designers and engineers can use this software to assess resiliency assets and explore the feasibility of renovations. Harnessing ecological change and environmental data to make informed cause-and-effect decisions puts you one step closer to reducing your footprint.
Asset management software/building management software
Meeting ambitious goals for sustainability requires energy efficiency at scale. Take advantage of data to manage integrated tech that supports life cycle modeling and analytics, maintenance schedules, and real-time reporting. Doing so means you extend the life of your buildings and reduce maintenance bills.
Fleet & equipment management systems
Preventing idle time and conserving fuel often comes second to the reality that a vehicle needs to be at the right place at the right time, or else it will derail the project schedule. The right fleet tech can increase operational efficiency. Keeping tabs on your commercial vehicle fleet with real-time tracking minimizes idling, optimizes driving routes, and promotes driving habits that improve fuel efficiency.
