“…Given Brazil's high solar irradiation, the use of water solar heaters is an alternative 30% more efficient than electric showers and with much room for growth [32,33]. The solar collectors heat the water by solar energy, which is sent to a boiler, which consists of a thermally insulated tank that keeps the water at a high temperature, making it available to be used in showers or faucets in general.…”

“…During this period, the electrical demand posed by showers might come to account for approximately 60% of a home´s electrical demand (Naspolini, Militão & Rüther, 2010 shower calls for the need to invest approximately US$ 1.000,00 (assumptions resting on the exchange rate during the period the study was published) to increase the electric generation capacity to power them (this figure´s current accuracy requires more refined research that literature does not offer. However, as of Graph 2 one notices that the electrical showers' aggregate demand determines the need for infrastructure to generate, transmit and distribute electricity which during the remaining hours of the day shall remain idle or under-utilized.…”

In Brazil, electricity is the prime energy carrier for bath shower heating purposes. However, since analyses indicate that expansion of the country´s electricity generation capacity shall spruce from an increased non-renewable sources' stake in detriment to that of hydroelectricity, high electricity consumption rates that spring from home end uses of the kind have drawn the attention of those who are involved with local energy planning. Furthermore, massive use of electric showers in a short timeframe largely drive electricity demands to culminate in peak loads.For water heating purposes, this context has favoured an alternative to electricity, deemed feasible from both an efficiency and energy infrastructure standpoint: promote fuel gas consumption (liquefied

RESUMO. Atualmente fontes de energia renováveis são exploradas para o desenvolvimento da sociedade e se destacam por serem mais limpas e menos poluentes. Entre estas fontes de energia renováveis, a energia solar é usada em sistemas de aquecimento solar de água, que tem entre seus objetivos, o de proporcionar economia de energia elétrica, pois fornece água quente sem a necessidade de utilizar sistemas elétricos, como o chuveiro elétrico, o qual é um dos aparelhos que mais consome energia. Para proporcionar economia do consumo de energia elétrica, minimizar impactos ambientais, redirecionar investimentos em novas fontes geradoras de energia elétrica, o Governo do Estado de São Paulo, em conjunto com a Companhia de Desenvolvimento Habitacional e Urbano do Estado de São Paulo -CDHU, como política de habitação, instalaram, nas residências de interesse social o sistema de aquecimento solar de água. O objetivo desta pesquisa foi comparar o consumo de água e energia elétrica, e variáveis socieconômicas entre dois conjuntos habitacionais, sem e com o sistema de aquecimento solar, na cidade de Ourinhos-SP. Os resultados permitiram concluir que existe diferença significativa entre os conjuntos de variáveis de consumo e as socioeconômicas. PALAVRAS-CHAVE:T 2 de Hotelling, consumo, socioeconômico, sistema de aquecimento solar, habitações de interesse social. WATER AND ELECTRICITY CONSUMPTION COMPARISON AND SOCIOECONOMIC INDICATORS ON HOUSING SETS WITH AND WITHOUT SOLAR HEATING SYSTEM.ABSTRACT: Currently, renewable energy sources are used to the society development and stand out for being less polluting. Among the renewable energy sources, the solar energy is used in water heating systems, that has among its objectives, to provide savings of electricity heating water without the need for electrical systems such as the electric shower which is one of the appliances that consume more energy. To provide energy consumption economy, minimize environmental impacts, redirect investment in new sources of electricity, the Government of the State of Sao Paulo, together with the Development Company of Housing and Urban of the State of Sao Paulo -CDHU, installed theses systems in homes of social interest. The objective of this research was to compare the consumption of water and electricity, and socioeconomic variables between two housing projects with and without solar heating system in the city of Ourinhos-SP. The results showed a significant difference between consumption and socioeconomic variables. INTRODUÇÃOOs sistemas de aquecimento solar de água são mais conhecidos e divulgados hoje em dia, seus benefícios são relevantes e a disponibilidade de diversas marcas e modelos no mercado faz com que estes sejam mais acessíveis às diferentes classes sociais.
