Lessons learnt from monitoring a sample of TVs and entertainment systems in Northern Italy

The use of entertainment devices is changing quickly. A number of different devices are normally connected to the main television set, and these devices change rapidly, and at the same time new behaviours are emerging. Indeed, people are willing to prefer the use of computers, tablets and smartphones instead of the television for their audio-visual entertainment. In order to better identify the number of entertainment devices that is actually used and their energy consumption, in 2017 the measurement campaign HESCA (Home Entertainment System Consumption Analysis) was promoted and developed in some households in Northern Italy. The consumption of 28 main televisions and 14 entertainment systems was measured on a daily basis for at least two weeks. Standby consumption was measured as well. On the basis of outcomes evaluated it results that these devices are responsible for 9.3 % of the total electricity consumption as an average of 5.6 % for televisions and 3.7 % of the attached devices. Standby consumption is still considerable high (3.6 % of the total electricity consumption) especially for satellite decoders. Some interesting correlations were studied highlighting the effect of the introduction of the energy labels or the increasing size of the TVs over time. The main results obtained are compared to those of the previous monitoring campaigns launched in Italy.
