The global push for sustainability has reshaped industries across the board, and technology is no exception. In the simulation hardware and software sector, where energy-intensive computing and rapid hardware cycles have historically left a significant environmental footprint, Aerosimulations stands out as a proactive leader. The company has embedded eco-friendly principles into every layer of its operations — from the materials used in its hardware to the code that powers its software — demonstrating that high-performance simulation does not have to come at the planet’s expense. This article explores the key pillars of Aerosimulations’ sustainability strategy, the concrete steps being taken, and the measurable impact achieved so far.

Eco-Friendly Hardware Initiatives

Aerosimulations recognizes that the physical infrastructure supporting simulation — servers, workstations, peripherals, and networking gear — accounts for a substantial portion of energy consumption and electronic waste. The company’s hardware initiatives are designed to address both the operational energy use and the lifecycle impact of these devices.

Energy-Efficient Servers and Computing Devices

At the core of Aerosimulations’ sustainable hardware approach is a commitment to energy-efficient computing. The company has transitioned its on-premises and co-located data centers to servers featuring the latest low-power processors, such as AMD EPYC “Bergamo” and ARM-based Ampere Altra chips, which deliver comparable performance at a fraction of the wattage of traditional Intel Xeon platforms. This shift has reduced per-server energy consumption by up to 45% in certain high-density simulation workloads.

Beyond the processor, Aerosimulations specifies power supplies that operate at 80 PLUS Titanium efficiency levels (≥96% efficiency at typical loads) and uses solid-state drives (SSDs) over spinning hard disks wherever possible — not only for speed but because SSDs consume roughly 60% less power per terabyte. The company also employs dynamic voltage and frequency scaling (DVFS) and aggressive power management policies that put idle resources into deep sleep states automatically, further lowering the base load.

Aerosimulations has also invested in low-power computing devices for edge simulation scenarios. For example, its portable training modules run on NVIDIA Jetson AGX Orin modules, which deliver high-performance AI inference and graphics rendering at just 15–75 watts — a fraction of the power required by desktop-class GPUs. This makes it feasible to deploy realistic simulation environments in remote or mobile settings without relying on heavy generators or grid connections.

Recyclable and Modular Component Design

To address the end-of-life challenge, Aerosimulations has worked closely with contract manufacturers to design hardware that is easier to repair, upgrade, and recycle. Chassis are constructed from recyclable aluminum and high-grade polymers free of brominated flame retardants. Internal components — memory modules, storage drives, and expansion cards — use standard connectors and are tool-less installable, enabling users to replace or upgrade individual parts rather than discarding entire units.

The company's flagship simulation workstations feature modular power supplies that can be swapped out when they degrade, and the mainboard layout avoids glued or soldered components that are difficult to separate during recycling. This design philosophy extends to the packaging: shipping materials are 100% recyclable, made from post-consumer recycled cardboard with no plastic foam. Aerosimulations reports that over 85% of the weight of each hardware unit can now be recovered and recycled through standard e-waste streams.

Sustainable Manufacturing Partnerships

Hardware sustainability is only as strong as the supply chain behind it. Aerosimulations has established partnerships exclusively with manufacturers that hold ISO 14001 (environmental management) and OHSAS 18001 (occupational health and safety) certifications. These partners are required to report their carbon footprint annually and commit to year-over-year reductions.

One notable collaboration is with Foxconn’s green manufacturing facility in Tianjin, China, which runs on 100% wind and solar energy. This facility produces several of Aerosimulations’ custom server racks using recycled aluminum for the chassis and lead-free solder for all connections. The company also sources raw materials from suppliers that adhere to the Conflict-Free Sourcing Initiative, ensuring that metals such as tin, tantalum, tungsten, and gold are extracted without funding armed conflict or contributing to environmental degradation.

Aerosimulations publishes an annual Environmental, Social, and Governance (ESG) report that includes a detailed supply chain sustainability scorecard. In its most recent report, it noted that 76% of its top-tier suppliers met the company’s stringent environmental criteria, with a target of 95% by 2027.

Comprehensive Recycling and Take-Back Programs

Aerosimulations operates a global e-waste take-back program for both institutional and individual customers. When a customer upgrades hardware, the company provides free shipping labels and arranges for certified e-waste processors to dismantle and recycle the equipment. The program accepts not only Aerosimulations-branded hardware but also any electronics the customer wishes to dispose of responsibly, reducing the burden of managing multiple vendors.

Recycling is performed in compliance with the European WEEE Directive, the U.S. EPA’s Responsible Recycling (R2) practices, and the Basel Convention on transboundary movements of hazardous wastes. Materials recovered — including copper, aluminum, precious metals from circuit boards, and rare earth elements from magnets — are sold back into secondary markets, with proceeds directed toward reforestation projects in partnership with One Tree Planted. In 2024 alone, the program diverted 430 metric tons of electronic waste from landfills.

Eco-Conscious Software Development

While hardware changes are visible, many of the most powerful sustainability interventions happen at the software level. Aerosimulations has made eco-consciousness a foundational design principle for its simulation platforms, optimizing algorithms and infrastructure to reduce energy consumption during development, deployment, and runtime.

Energy-Efficient Architecture and Server Load Reduction

The company’s main simulation engine, SimCore, was re-architected to minimize CPU idle time. It uses an event-driven, non-blocking I/O model that keeps threads busy only when there is work to perform, rather than polling or spinning. This change alone reduced server idle power consumption by 30%. Additionally, SimCore features a “green mode” that dynamically scales simulation fidelity based on the complexity of the scenario: if a simulation involves few dynamic objects, the engine reduces physics tick rate and shading quality, cutting power draw by up to 50% without noticeable degradation in user experience.

Data transfer is another major energy consumer in simulation networks. Aerosimulations has implemented intelligent caching and delta synchronization algorithms. When updating simulation state across multiple clients, only the changes (deltas) are transmitted, often reducing bandwidth usage by 70%. This means less energy expended in routers, switches, and end devices for transmission. The company also uses modern video codecs (H.265 and AV1) for any visual streaming, requiring fewer bits per frame and less processing power on the decoding end.

Green Coding Practices

The software engineering team at Aerosimulations adheres to a strict “green coding” checklist during development. This includes:

  • Algorithmic efficiency – Choosing O(n log n) or O(n) algorithms where possible, avoiding brute-force approaches.
  • Resource deallocation – Explicitly freeing memory and file handles to prevent leaks.
  • Energy-aware threading – Using thread pools sized to the number of physical cores, preventing context-switching overhead.
  • Compiler optimizations – Compiling with -O3 and profile-guided optimizations to produce faster, cooler-running machine code.
  • Lazy loading – Loading textures, meshes, and scripts only when they first appear in the simulation, rather than upfront.

These practices are enforced through automated code reviews and energy profiling tools such as Intel Energy Profiler and NVIDIA Nsight Systems. The company reports that green coding review gates have eliminated an average of 12% of wasteful CPU cycles from new feature releases, directly translating to lower energy bills and carbon emissions at customer sites.

Cloud-Based Solutions and Renewable Energy

Aerosimulations offers its platform as a fully managed cloud service (SimCloud) hosted on AWS, Google Cloud, and Azure. Each of these cloud providers has made public commitments to 100% renewable electricity — AWS aims for 100% by 2025, Google has matched its global electricity consumption with renewables since 2017, and Azure has committed to being carbon negative by 2030. By abstracting away on-premises hardware, SimCloud allows customers to shift their energy consumption to data centers powered by wind, solar, and hydro.

Furthermore, Aerosimulations uses spot instances and reserved capacity bidding to ensure that simulation workloads run during periods of lowest carbon intensity on the grid. The cloud scheduler integrates with Watttime’s Marginal Emissions API to automatically launch batch simulation jobs when the local grid has a higher proportion of renewable energy. In 2023, this feature alone reduced carbon emissions from cloud simulations by an estimated 18% compared to running on-demand at any hour.

For customers who must maintain on-premises deployments, Aerosimulations provides a “cloud-burst” hybrid capability: normal workloads run on local energy-efficient hardware, but spikes in demand are seamlessly offloaded to cloud regions powered by renewables. This ensures that even peak loads are handled with minimal carbon impact.

Impact and Future Goals

Aerosimulations’ sustainability strategy is not just aspirational — it is producing measurable results. The company publishes quarterly environmental impact metrics that are audited by a third-party environmental consultancy. Key achievements include:

  • Energy reduction – A 40% reduction in energy consumption per simulation session across all on-premises hardware since 2021, attributable to both hardware upgrades and software optimizations.
  • Waste diversion – Over 430 tons of e-waste recycled or responsibly processed through the take-back program, with a 95% recovery rate for precious metals.
  • Carbon footprint – Scope 1 and Scope 2 emissions decreased by 33% year-over-year in 2024, with Scope 3 emissions (supply chain) down 12%.

Looking forward, Aerosimulations has set ambitious targets:

  • By 2027, achieve 100% renewable electricity for all owned and leased facilities (currently at 67%).
  • By 2030, reduce absolute carbon emissions (Scopes 1, 2, and 3) by 50% from a 2022 baseline, validated by the Science Based Targets initiative (SBTi).
  • By 2035, all hardware sold must be fully circular — meaning 100% of materials can be recycled, and the company will guarantee a take-back for every unit.
  • Partner with universities to develop open-source tools for measuring and reducing software energy consumption, contributing to the broader green coding movement.

Aerosimulations is also exploring next-generation technologies such as direct liquid cooling for high-density simulation clusters, which can reduce cooling energy by 30% or more compared to air cooling. They are piloting a small-scale hydrogen fuel cell installation at their headquarters to provide backup power without diesel generators, further cutting emissions.
