Heat Waves and Energy Use: How Extreme Heat Drives Up Business Costs
Heat waves are getting more frequent and more intense, and their effects reach well beyond the obvious. Alongside droughts, wildfire risk and lower agricultural output, they have a direct and growing impact on energy consumption, and therefore on business costs. Since every sign points to the phenomenon intensifying, it is worth understanding how it hits and what you can do about it.
What exactly is a heat wave
A heat wave is usually defined as several consecutive days in which a meaningful share of a region's weather stations record high temperatures well above normal for the season. It is an increasingly common event: in Europe the first major extreme heat wave arrived in the early 2000s, and for several years now they have recurred almost every summer. Much of the United States sees the same pattern, especially in warmer states.
How heat waves drive up energy use
Two things happen at once. Cooling systems, air conditioning and ventilation, spike across offices and industrial plants. And a lot of industrial equipment has to work harder to stay within its recommended temperature range, pushing consumption up sharply during heat peaks. That surge in electricity demand also raises the emissions tied to generation, particularly in systems that still lean on non-renewable sources to cover peak load. In the US, those same peaks are what push up demand charges, the part of a commercial bill tied to your highest interval of use, so a heat wave can hit the bill twice: more kWh, and a higher demand peak.
How to reduce the impact of heat waves on your energy use
Organizations need tools that keep consumption under control at all times, including against external factors like a heat wave. Cooling can carry serious weight during peak-demand periods, and with hotter summers that pressure is only likely to grow.
That is why it helps to bring in solutions that improve efficiency and cut consumption without sacrificing comfort. Smarkia's energy management system applies AI and machine learning to HVAC and cold-chain processes. The platform monitors and analyzes consumption data in real time, anticipating the energy demand that different factors, weather included, will create, so companies can make informed decisions ahead of time instead of reacting on the fly.
In real client cases applying this approach to HVAC and cold chain, the savings reach up to 20% on cooling-related electricity and up to 40% on cold chain, figures in line with what is seen consistently across industry and commercial settings. Companies such as Repsol and CBRE, both Smarkia clients, have applied this kind of solution across their sites to gain control over energy use at the most demanding moments.
The data is clear: heat waves will keep getting more extreme and more frequent, in Spain and the United States alike. Smarkia keeps working to help companies control their energy use, cut emissions and hold the balance between operations and sustainability, wherever the heat comes from.
