Abstract
Buildings consume more than one-third of the world's primary energy. Therefore, as the population grows, so will the demand for energy. There are two approaches to this scenario: generate more energy in a clean and renewable way or reduce energy consumption in buildings through an energy efficiency strategy. The key question is how far energy efficiency measures will go in terms of economic benefits. In this context, the general objective of the study is to investigate the balance between reducing energy consumption and generating photovoltaic energy in single-family homes of social interest. The consumption avoided by energy efficiency measures was used to size the photovoltaic systems, so that the performance and economic profitability of both systems were compared, leading to a reduction in energy demand and the generation of clean energy. The results show that efficiency measures are not economically efficient compared to photovoltaic systems. In all assumed scenarios, photovoltaic systems are better from a financial point of view.
