Reducing consumption is not enough. What is truly necessary?

Reducing energy consumption is one of the most common goals, regardless of the context. Companies, offices, retail activities and public administrations are all trying to consume less.

However, this approach often starts from the assumption that all consumption has the same value, when in reality this is far from true.

Within any building or infrastructure, very different situations coexist. Some forms of consumption are essential to operations, some can be optimized, while others simply exist because they have never been questioned. They can be summarized as follows:

• Necessary consumption;
• Optimizable consumption;
• Unnecessary consumption.

The limitation of linear strategies

When action is taken uniformly, without this deeper analysis, the result is often only partial improvement. Indiscriminate reduction can negatively impact operations, generate limited benefits and leave real inefficiencies untouched.

On the other hand, identifying what is truly unnecessary allows for far more effective interventions.

Consuming better, not just less

In recent years, a different approach has started to emerge, one based on the quality of consumption. The goal is not simply to reduce energy use, but to use energy in a way that better reflects the actual use of spaces.

This means, for example:

• Providing lighting only when needed;
• Adjusting light levels according to environmental conditions;
• Preventing static systems from operating the same way in every situation.

From numbers to behaviour

Real change happens when consumption is analysed over time, not as an isolated figure, but as a genuine behaviour pattern.

It is through this perspective that anomalies, waste and opportunities emerge — elements that would otherwise remain hidden. Rather than simply asking how much consumption can be reduced, perhaps we should ask ourselves how much of the energy we are using is actually necessary.
