The AI Boom Is Rewriting the Energy Equation

From data centers to chip foundries, the AI boom has ignited a new kind of industrial revolution. Major tech firms (such as Nvidia, Microsoft and others) are no longer waiting for the U.S. grid to catch up; they’re building their own power plants. In fact, one analysis finds that electricity costs in some regions near large AI data centre installations have surged up to 267% compared with five years ago. (Bloomberg)

It’s not just abstract. In the U.S., wholesale electricity prices that would have been modest in 2020 are now far higher in data-centre hotspots. (Sandbox)

Why is this relevant?

These high-demand loads strain the grid, making the cost of electricity (and grid services) higher for everyone.
The more power-hungry the infrastructure becomes, the greater the business risk for enterprises that rely on stable, affordable energy.
As grid infrastructure lags behind demand, companies and organizations have to ask: What control do we have over our energy consumption?

When Power Becomes a Premium

Every kilowatt-hour now carries more weight, especially for companies operating large buildings or complex HVAC systems (sound familiar?). Efficiency isn’t just an ESG metric anymore; it’s a business imperative tied directly to cost-control and resilience.

We’re now at a moment where:

Renewables are expanding fast, but demand is rising even faster in some tech/industrial sectors. For example, the International Energy Agency (IEA) projects that electricity demand from data centres will more than double by 2030 to around 945 TWh — “more than four times faster than the growth of total electricity consumption from all other sectors”. (IEA)
Some regions are seeing localized shortages, transmission constraints and higher wholesale power prices. In the U.S., wholesale electricity prices in several markets were up by 40-80 % in 2025 compared with 2024. (Construction Physics)
Organizations that wait for the “grid fix” may find themselves paying a premium (or exposed to reliability risk) in the meantime.

Put simply: If you can’t fully control your energy supply, you must control your energy use. Efficiency becomes the operational hedge.

The Efficiency Imperative

Here’s where the story turns from macro trends into actionable insight. The good news: The same technologies driving smarter AI are also enabling smarter buildings and systems. Intelligent filtration, automation, low-pressure HVAC systems, demand-response strategies — these are the tools to control the energy side of the business.

Here are three reasons why now is the time to focus on performance and efficiency:

Cost Avoidance Becomes Value Creation
With energy prices under pressure and demand growth uncertain, reducing consumption becomes a direct cost-mitigation strategy.– Efficiency improvements often pay back faster when baseline energy costs are rising.
Grid Risk = Business Risk
Relying solely on external supply (even if green) is a vulnerability; the more you rely on the grid, the more you’re exposed to spikes, shortages or regulatory premium pricing.– Being energy-efficient gives you more independence and control.
Sustainability Meets Differentiation
With the global pivot to renewables (for example, the projection that global renewable capacity additions between 2025-2030 will be ~4,600 GW) IEA — the organisations that get ahead now won’t just be “green” — they’ll be efficient green. That matters for brand, operations, risk profile.

When you think about building automation, indoor air quality and HVAC systems, you’re often dealing with the largest energy loads after lighting in a built environment. By focusing on filtration, optimization and smart control, you’re reducing both the peak load and the total energy used, which in the current climate is exactly the kind of strategic leverage organizations need.

Yes: the news about renewables overtaking coal is encouraging — that shift shows progress. But it also hides a key truth: demand is increasing fast, thanks in part to data, AI, buildings and more.
That means supply-side improvements alone aren’t enough. They must be matched by demand-side discipline (i.e., efficiency).
Organizations that act now to optimize their energy consumption will be better positioned, from cost, risk and sustainability standpoints, in the years ahead.

So whether you’re managing a campus, commercial building or industrial facility: don’t wait for the grid to “catch up.” Focus on what you control. Because in this new power era, efficiency is the real currency.

Man using an AQI app on his phone to see what the air quality status is — By understanding the AQI and adhering to the corresponding health recommendations, you can take proactive steps to protect your health and the health of those around you.

Air quality has a significant impact on our overall health and well-being. As wildfires and other sources of air pollution become more prevalent, understanding the Air Quality Index (AQI) becomes increasingly important.

The AQI is a valuable tool that helps individuals determine the quality of the air they breathe and take necessary precautions to protect their health. In this blog, we will explore what AQI is, how it's calculated, and its impact on health, providing you with the knowledge to make informed decisions about your indoor and outdoor activities.

Understanding the Air Quality Index (AQI)?

The Air Quality Index (AQI) is a standardized system used by government agencies, environmental organizations, and health authorities to communicate the level of air pollution to the public.

The AQI converts complex air quality data into a single number and colour-coded scale, making it easier for people to understand the air quality in their area and its potential health effects.

The AQI scale ranges from 0 to 500 and is divided into six categories:

Good (Green): AQI 0-50
Moderate (Yellow): AQI 51-100
Unhealthy for Sensitive Groups (Orange): AQI 101-150
Unhealthy (Red): AQI 151-200
Very Unhealthy (Purple): AQI 201-300
Hazardous (Maroon): AQI 301-500

How is the AQI Calculated?

The AQI is calculated based on the concentrations of five major air pollutants regulated by the Clean Air Act:

Ground-level ozone (O3)
Particulate Matter (PM10 and PM2.5)
Carbon Monoxide (CO)
Sulphur Dioxide (SO2)
Nitrogen Dioxide (NO2)

Each pollutant has its own sub-index, which is calculated from its concentration in the air over a specified averaging period (e.g., 1 hour, 8 hours, or 24 hours). The highest of these sub-indices determines the overall AQI for that location on a given day.

For example, during wildfire events, PM2.5 levels often dominate the AQI due to the abundance of fine smoke particles in the air.

AQI Categories and Health Recommendations

To help you interpret the AQI and understand its implications, let's break down each category and the corresponding health recommendations:

Air Quality index chart as per the US Environmental Protection Agency — The Air Quality Index includes AQI categories and colors, corresponding index values and cautionary statements for different levels of health concern.

Good (Green): AQI 0-50
1. Air Quality: Satisfactory; air pollution poses little or no risk.
2. Health Recommendations: No special precautions are needed.
Moderate (Yellow): AQI 51-100
1. Air Quality: Acceptable; however, for some pollutants, there may be a moderate health concern for a very small number of people who are sensitive to air pollution.
2. Health Recommendations: Unusually sensitive individuals should consider reducing prolonged outdoor exertion.
Unhealthy for Sensitive Groups (Orange): AQI 101-150
1. Air Quality: Members of sensitive groups may experience health effects. The general public is less likely to be affected.
2. Health Recommendations: Children, the elderly, and individuals with respiratory or heart conditions should limit prolonged outdoor exertion.
Unhealthy (Red): AQI 151-200
1. Air Quality: Everyone may begin to experience health effects; members of sensitive groups may experience more serious health effects.
2. Health Recommendations: All individuals should limit prolonged outdoor exertion; sensitive groups should avoid outdoor activity.
Very Unhealthy (Purple): AQI 201-300
1. Air Quality: Health alert; everyone may experience more serious health effects.
2. Health Recommendations: Limit outdoor activities; sensitive groups should remain indoors and keep windows closed.
Hazardous (Maroon): AQI 301-500
1. Air Quality: Health warning of emergency conditions; the entire population is more likely to be affected.
2. Health Recommendations: Avoid all outdoor activity; stay indoors with windows and doors closed.

The Health Impact of Different Pollutants

The AQI focuses on five major pollutants, each of which affects health in specific ways:

Ground-level Ozone (O3)
1. Sources: Motor vehicle emissions, industrial facilities, chemical solvents.
2. Health Effects: Respiratory problems, reduced lung function, aggravated asthma, throat irritation.
Particulate Matter (PM10 and PM2.5)
1. Sources: Construction sites, unpaved roads, fields, smokestacks, fires.
2. Health Effects: Cardiopulmonary diseases, aggravated asthma, diminished lung function, respiratory infections, heart attacks, strokes.
Carbon Monoxide (CO)
1. Sources: Motor vehicle emissions, industrial processes, residential heating sources.
2. Health Effects: Reduced oxygen delivery to the body’s organs and tissues, fatigue, chest pain, impaired vision, and reduced brain function, at high levels may cause death.
Sulphur Dioxide (SO2)
1. Sources: Fossil fuel combustion at power plants and industrial facilities.
2. Health Effects: Irritation of lungs and airways, increased asthma symptoms, reduced lung function.
Nitrogen Dioxide (NO2)
1. Sources: Motor vehicle emissions, power plants, industrial facilities.
2. Health Effects: Lung irritation, respiratory infections, increased asthma symptoms.

Monitoring and Reducing Exposure to Poor Air Quality

Understanding the AQI and its implications is the first step in protecting your health from air pollution. Here are some practical steps to monitor air quality and minimize exposure:

Monitoring Air Quality
