The Role of Data Centres and Smart Community in Illinois

Aurora, Illinois is building a model that connects community sustainability with the realities of data centre expansion, combining energy-efficient housing with firm regulatory controls on digital infrastructure.

The city’s approach reflects a broader challenge – how to balance rising demand for compute capacity with local energy systems, water resources and community impact. While Aurora develops smart homes powered by renewable energy, it is also setting boundaries for how data centres operate within its limits.

This dual focus places energy management at the centre of both residential and digital infrastructure planning.

Energy efficiency from homes to infrastructure

Aurora’s housing developments prioritise reducing energy demand through advanced construction and integrated technologies. Insulating concrete form walls – a building method using reinforced concrete and insulation – alongside spray foam insulation and high-efficiency windows, limit heat loss and reduce the energy required for heating and cooling.

Heat recovery ventilation systems, which capture and reuse heat from outgoing air, further cut energy consumption while maintaining indoor air quality. Homes also include smart thermostats, energy-efficient appliances and tankless water heaters, allowing residents to manage energy use in real time.

Solar panels and battery storage systems extend this model by generating and storing electricity on site. This creates a decentralised energy system where homes can operate with greater independence from the grid, particularly during peak demand or outages.

Electric vehicle chargers and smart electrical panels add another layer, enabling residents to track how energy is produced stored and consumed across the home.

John Laesch, Mayor of Aurora, Illinois, connects these initiatives to wider policy ambitions. “These innovative ordinances will help establish significant safeguards for our residents and the environment moving forward,” he says.

“With these local regulations now in place, it’s time for the State of Illinois to follow suit and pass the Illinois POWER Act.

“This piece of common-sense legislation will assist Illinoisians who are suffering from high electricity bills, while helping to enhance of life for communities across the state.”

Data centre regulation takes shape

Alongside residential development, Aurora is addressing the growing presence of data centres, which introduce new pressures on energy infrastructure and resources. Facilities of this kind require large volumes of electricity for compute workloads and cooling systems, often placing strain on local grids.

In response to increasing development proposals, the city has introduced a moratorium on new data centre projects while it develops a regulatory framework. New ordinances now require conditional use approval, including public hearings, before construction can begin.

These rules place energy performance at the centre of approval criteria. Data centres must meet strict power usage effectiveness targets.

Developers are also required to include on-site renewable energy generation or battery storage, alongside detailed modelling of energy consumption. This ensures that projects account for long-term demand on the grid before approval is granted.

Water usage is another key factor. Cooling systems in data centres can rely heavily on water, so the city mandates impact studies limits on water usage effectiveness and the adoption of more sustainable cooling technologies.

Noise and vibration are addressed through baseline assessments, continuous monitoring and defined limits – with additional requirements for setbacks from residential areas.

Alison Lindburg, Director of Sustainability at the City of Aurora, Illinois, outlines how these measures are developed.

“These new regulations are the result of months of work from City staff, who conducted extensive research and engaged the public to gather feedback on the future of data centre development in Aurora,” she says.

“We will continue to keep our residents’ needs front and centre as we work with developers who are committed to meeting these standards.”

Managing demand and community impact

Aurora’s framework reflects wider pressures on energy and water systems in northern Illinois. Declining groundwater levels and rising electricity demand are shaping how new infrastructure is approved and operated.

By requiring annual reporting on energy, water and noise performance, the city ensures ongoing accountability for data centre operators. Non-compliance can lead to financial penalties, reinforcing the importance of meeting defined standards.

The city has also introduced rules around data privacy and AI, requiring written consent and clear policies for data use. While not directly linked to energy, these measures reflect broader concerns about the social impact of digital infrastructure.

Through this combined approach, Aurora is aligning energy-efficient housing with stricter oversight of data centres, ensuring that both forms of development operate within defined environmental and infrastructure limits.
