Energy efficiency: what it is, how to improve it
Energy efficiency is increasingly a central topic in public debate.
But what is meant by energy efficiency and how can we improve it to make our contribution to the environment?
What is meant by energy efficiency?
Energy efficiency refers to the ability to obtain maximum performance with minimum energy consumption . It's about using energy more intelligently and efficiently, reducing waste and optimizing the use of available resources.
Difference between energy efficiency and energy efficiency
Energy efficiency and energy efficiency are often confused, or used interchangeably, but there is a difference. Specifically, energy efficiency is about the optimal use of energy. For example, in the case of a property, energy efficiency refers to the amount of energy the house needs for its operation. energy efficiency focuses on actions and interventions to improve the use of energy , for example through the installation of more efficient devices or the thermal insulation of buildings.
Energy efficiency classes: what are they?
From 2021, the European Union has standardized and revised the indications for energy efficiency classes , commonly indicated with energy labels , now ranging from A (more efficient) to G (less efficient) . These ratings provide insights into the energy consumption and performance of equipment and devices, allowing consumers to make informed choices.
How to improve energy efficiency at home
Improve energy efficiency of a house does not only mean carrying out large efficiency works, such as the coat, but also making small, but decisive, measures.
Here are some examples:
- Use low consumption energy or LED light bulbs
- Install programmable thermostats to better manage heating and cooling
- Insulate walls, floors and roofs to reduce heat losses
- Replace old and inefficient appliances with newer, energy-efficient models
Energy efficiency and boiler: why do the overhaul
Although boiler overhaul is often seen as a cost, in reality the inefficient boilers can consume more energy than necessary and increase operating costs . Regular maintenance and overhaul ensures optimal operation, reducing heating consumption and prolonging the life of the device.

Adjust the temperature of your home for better energy efficiency
Even the use of a chronothermostat , instead of a normal thermostat , helps reduce consumption and costs related to heating.
The possibility of setting a comfort temperature and a reduction temperature on an hourly basis allows you to reduce energy consumption by avoiding heating rooms when it is not necessary.
In this regard, what temperature should we have in the house in winter? According to WHO guidelines, ideal temperature is around 20-21 °C . For further advice on how to save with the thermostat you can read our in-depth analysis dedicated to this topic .
