Abstract

Residential energy consumption monitoring is essential for promoting energy efficiency and managing billable costs. However, many consumers face difficulties in understanding the individual impact of their household appliances on the monthly bill. This paper presents an analysis and development of a software prototype designed to estimate residential electricity consumption and costs, including a complementary module for solar generation simulation. The solution utilizes equipment power ratings, usage time, and tariff parameters to calculate the estimated consumption in kWh and in Brazilian Reais (R\$). Based on a data survey with 26 consumers, the investigation pointed out the lack of time for monitoring, tariff complexity, and the absence of accessible tools as the main obstacles to energy management.The practical demonstration of the prototype evidenced that it offers a viable computational alternative to assist in conscious decision-making, mitigating the dependence on physical meters.
