Evaluation of household electricity savings. Analysis of household electricity demand profile and user activities

摘要

To achieve reduction in electricity consumption, it is vital to have current information about household electricity use. This allows to draw user behaviour profile based on household electricity demand for a specific time of the day. Activities involving the use of electricity for certain purposes, time of use survey and smart metering data of a four people family were analysed in this study. Household energy efficiency performance till 2020 was evaluated based on increase of equipment energy efficiency driven by technological progress. The results of energy efficiency evaluation for particular household shows that 1219 kWh savings can be achieved due to improvements of energy performance of some mostly used appliances until 2020 (i.e., reduction in electricity consumption of 13 % if compared to present scenario). However, the results imply that user behaviour change is also important to implement the measures associated with energy efficiency improvements in households.
