Abstract(s)
O recurso às energias renováveis é na actualidade um tema que atinge um grau de importância primordial face á crescente preocupação com o meio ambiente e o impacto negativo, que a produção de energia com base em combustíveis fósseis tem.
Esta importância aliada a uma tendência cada vez maior para a criação de soluções de produção sustentável de energia, tem obrigado ao desenvolvimento desta vertente do sector energético e ao estudo e consequentemente implementação de soluções integradas que permitam uma economia competitiva.
Os hotéis, sendo estabelecimentos comerciais que desenvolvem uma actividade que envolve, na generalidade, um nível de consumo energético considerável para garantir os seus serviços básicos de acomodação e lazer, tornam-se por excelência alvos primordiais no que concerne ao seu elevado potencial de poupança de energia. O ramo da hotelaria, dada a sua especificidade e a natureza dos edifícios que comporta, torna-os em excelentes candidatos para análise e optimização energética, e como tal um
alvo de negócio para as empresas de comercialização de poupanças energéticas.
As empresas dedicadas aos serviços de energia são conhecidas por ESCO (Energy Service Company ou Energy Savings Company). A sua actividade tem por base apresentar soluções de energia, nomeadamente a implementação de projectos de poupança energética que podem englobar produção, conservação e fornecimento de energia, bem como gestão de risco associada. O objectivo principal é apresentar soluções de optimização e eficiência energética levando á sua implementação em casos reais de exploração em edifícios ou sectores específicos, rentabilizando o investimento e partilhando o lucro dessa rentabilização com os clientes. No caso específico dos hotéis, mais concretamente um complexo de hotéis, como o estudado neste trabalho, esta análise pretende elaborar uma caracterização das necessidades energéticas do sector e apresentar um conjunto de soluções energéticas adequadas à realidade hoteleira. É também objecto de análise, toda a aproximação de um modelo de negócio energético a explorar por uma ESCO.
O presente trabalho, realizado no âmbito da parceria entre a Gebio e a Confraria do Bom Jesus, tem por objectivo demonstrar as bases do contracto de performance entre uma empresa ESCO (Gebio – empresa concessionária do projecto) e um complexo de hotéis (constituído pelo Hotel do Lago, Hotel do Parque e Hotel do Templo), com vista a optimizar os consumos energéticos para a produção de energia térmica capaz de corresponder às necessidades do complexo. Foi desenvolvido um estudo completo das
necessidades térmicas do complexo, com vista a projectar uma solução integrada de produção de energia térmica, com recurso a uma caldeira de biomassa, para os hotéis. Foi realizado um levantamento extensivo dos consumos e custos energético do complexo, nomeadamente para as águas quentes sanitárias. Desta análise obtiveram-se os custos reais do sistema e com os mesmos foi possível, numa primeira fase, elaborar os diversos projectos, hidráulico, eléctricos e civil, de forma a se definir a solução base e quais os orçamentos previstos para a instalação de um sistema de produção a biomassa, e numa segunda fase foi estudada a viabilidade da assinatura de um contracto de performance entre a ESCO e o complexo de hotéis.
The use of renewable energies is today a theme that reaches a level of paramount importance given the growing concern for the environment and the negative impact that energy production from fossil fuels has. This importance, combined with a growing trend towards the creation of sustainable energy production solutions, has forced the development of this area of the energy sector and to the study and therefore implementation of integrated solutions to achieve a competitive economy. Hotels, being commercial establishments that develop an activity that involves, in general, a considerable energy consumption level to ensure their basic services of accommodation and leisure, become primary targets, for excellence, in terms of its potencial high energy savings. The branch of the hotel industry, given its specificity and the nature of its comprising buildings, makes them excellent candidates for energy analysis optimization, and because of this, a business target for companies marketing energy saving solutions. The companies dedicated to energy services are known as ESCO (Energy Service Company or Energy Savings Company). Their activity is based on presenting energy solutions, including the implementation of energy saving projects which may include production, conservation and energy supply, as well as associated risk management. The main objective is to provide optimization solutions and energy efficiency leading to its implementation in real cases of exploitation in buildings or specific sectors, maximizing investment and profit, sharing this profitability with customers. In the specific case of hotels or a complex of hotels, as studied in this work, this analysis aims to develop a characterization of the energy needs of the sector and present a set of appropriate energy solutions to the hotel industry reality. It is also analyzed, the whole approach of an energy business model to explore by an ESCO. The present work, conducted in partnership between Gebio and the Comradeship of Bom Jesus, aims to demonstrate the basis of a performance contract between an ESCO company (Gebio - concessionaire of the project) and a hotel complex (consisting of the Hotel do Lago, Hotel do Parque e Hotel do Templo) in order to optimize the energy consumption for the production of thermal energy capable of meeting the needs of the complex. It was developed a complete study of the thermal complex needs in order to design an integrated solution for thermal energy production for the hotels, using a biomass boiler. An extensive survey of consumptions and energy complex costs was made, particularly for hot water. From this analysis, the actual system costs were obtained, and with this elements it was possible, in a first fase, to elaborate the various projects, hydraulic, electrical and civil, in order to set the base solution and the planned budgets for the installation of a biomass production system, and in the second stage was studied the feasibility of signing a performance contract between the ESCO and the hotel complex.
