No. of bitstreams: 1 000401161-Texto+Completo-0.pdf: 3203510 bytes, checksum: 5f982969daeb4904827ef17bc67ef11c (MD5) Previous issue date: 2008 / This study aimed to assess the potential for energy saving in the Hospital Sector in the South Region of Brazil and its impact on the mitigation of carbon dioxide emission to the atmosphere, achieved through the reduction in the consumption of electricity. The study analyzed sixteen hospitals where energy saving projects has been implemented. Each hospital has been monitored before and after the implementation of energy saving projects through energy audits conducted by the Research Group on Energy Efficiency from PUCRS. Moreover, the study used data from the IBGE and DATASUS. The estimation of energy saving and other values of interest was carried out according to methodologies based on population statistics. As the first step, it was calculated the mean values of consumption and demand before energy efficiency projects, reductions in consumption and demand after energy efficiency projects, and the necessary financial investments. All relevant data have been normalized using the number of available beds on each hospital. As a second step, through the calculation of the linear regression, it was found the estimated consumption of each of the hospitals in the South Region of Brazil. Summing up the individual data, it was possible to obtain the values for the whole population, which was in the sequence compared to the mean values in order to verify its coherence. As a result, for the whole population, it was found an annual consumption of 548 GWh of energy and a power demand of 112 MW, which could be achieved with projects aiming to improve the efficiency of the use of electrical energy. It was also found that such projects could lead to a reduction of 171. 54 GWh on the energy consumption and 43. 5 MW of power demand. However, this would also require an investment of R$ 157. 08 million. Taking into account the avoided costs for the expansion of the electrical system to meet the same power demand, this investment would be paid in 3. 6 years. Concerning environmental impacts, such energy conservation actions would allows avoiding the emission of 164 thousand tones of CO2 per year. Finally, this study shows the great importance of energy saving in the hospital sector and the benefits that actions of energy conservation would have to the society. / Este trabalho teve como objetivo avaliar o potencial de economia de energia no Setor Hospitalar da Região Sul do Brasil, bem como os impactos quanto à mitigação de dióxido de carbono na atmosfera, alcançados através das reduções no consumo de eletricidade. Para tanto a pesquisa contou com dezesseis hospitais, cada qual com seu diagnóstico energético elaborado pelo Grupo de Eficiência Energética da PUCRS. Além disso, o trabalho utilizou dados do DATASUS e do IBGE. Os cálculos para a estimação dos valores populacionais seguiram metodologias baseadas na estatística, onde, primeiramente, calcularam-se as médias aritméticas de: consumo e demanda antes de projetos de eficiência energética, reduções de consumo e demanda após as ações de eficiência energética e investimento, todos relacionados com o número de leitos disponível à internação. Posteriormente, através do cálculo da regressão linear, foi encontrado o consumo estimado de cada um dos hospitais da Região Sul do país e, somados os dados individuais, obtiveram-se os valores para a população. Estes valores foram comparados com os encontrados por meio da média a fim de se verificar a pertinência dos mesmos. Como resultados, encontrou-se para a população um consumo anual de 548 GWh e uma demanda de energia de 112 MW, onde, realizando ações de eficiência energética alcança-se uma redução de 171,5 GWh de consumo e 43,5 MW de demanda, necessitando-se de um investimento de R$ 157,08 milhões. Levando em conta os custos evitados para a ampliação do sistema elétrico no intuito de atender a mesma demanda, este investimento seria pago em 3,6 anos. No que tange aos impactos ambientais, com tais ações de conservação de energia, evita-se a emissão de 164 mil toneladas de CO2 por ano. Assim, este trabalho mostra a grande importância de se combater o desperdício de energia elétrica no setor e os benefícios que as ações de conservação de energia trariam para a sociedade.
