Resumo(s)
A União Europeia (UE) definiu, em paralelo ao Acordo de Paris, um conjunto de metas a serem alcançadas de 2021 até 2030. Dentre essas, redução nas emissões de Gases de Efeito Estufa (GEEs), aumento em energia instalada proveniente de fontes renováveis e um acréscimo em eficiência energética. Nesse sentido, a atual equipa de gestão da Herdade São Lourenço do Barrocal a partir do seu plano de sustentabilidade evidencia uma preocupação social e ambiental em suas atividades.
Em contrapartida, os hotéis estão entre as instalações turísticas com maior consumo de energia e água per capita. Esses insumos são responsáveis por grande parte dos custos operacionais e seu elevado consumo é essencial para manter o nível de conforto exigido pelos hóspedes em hotéis de luxo. Assim sendo, é fundamental atuar o quanto antes nesse segmento hoteleiro para atingir os objetivos de longo prazo impostos pela União Europeia.
Dito isto, esse trabalho faz um diagnóstico energético acerca do consumo de energia elétrica da Herdade São Lourenço do Barrocal, com o objetivo de: introduzir um Sistema de Gestão de Energia Elétrica (SGEE) baseado nos requisitos da norma ISO 50001:2018, sugerir medidas de eficiência energética e elaborar um Projeto de Instalação Solar Fotovoltaico para autoconsumo. Além disso, foi possivel: estabelecer um framework para efetuar melhorias contínuas no desempenho energético, desagregar os consumos, identificar os Usos Significativos de Energia (USE), fragmentar os consumos por categorias e setores, identificar variáveis que afetam consumo e, finalmente, construir um dashboard de gestão.
Com os resultados do diagnóstico energético, foi observado que os quartos, as casas e a cozinha foram os setores de maior consumo, a representar respectivamente 31,54%, 13,10% e 9,12% do consumo médio total. Em outra análise foi possível concluir que as categorias AVAC, iluminação e bombagem representam respectivamente 18,53%, 17,68% e 14,04% do consumo médio total. O projeto solar fotovoltaico desenvolvido indicou como melhor opção um sistema com potência instalada de 175,05 kWp, uma taxa interna de rentabilidade de 23,31%, autoconsumo de 92,63% e um payback de 5 anos.
The European Union (EU) defined, in parallel with the Paris Agreement, a set of goals to be achieved from 2021 to 2030. Among these, reduction in Greenhouse Gas (GHG) emissions, increase in installed energy from renewable sources and an increase in energy efficiency. In this sense, the current energy management of Herdade São Lourenço do Barrocal based on its sustainability plan demonstrates a social and environmental concern in its activities. In contrast, hotels are among the tourist facilities with the highest consumption of en-ergy and water per capita. These inputs are responsible for a large part of operating costs and their high consumption is essential to maintain the level of comfort required by guests in lux-ury hotels. Therefore, it is essential to act as soon as possible in this hotel segment to achieve the long-term goals imposed by the European Union. That said, this work makes an energy diagnosis about the electricity consumption of Herdade São Lourenço do Barrocal, with the objective of: introducing an Electric Energy Man-agement System (SGEE) based on the requirements of the ISO 50001:2018 standard, suggest-ing measures energy efficiency and prepare a Solar Photovoltaic Installation Project for self-consumption. In addition, it was possible to: establish a framework to make continuous im-provements in energy performance, disaggregate consumption, identify Significant Uses of Energy (USE), fragment consumption by categories and sectors, identify variables that affect consumption and, finally, build a management dashboard. As a result of the energy diagnosis, it was observed that the bedrooms, houses and kitchen were the sectors with the highest consumption, representing respectively 31.54%, 13.10% and 9.12% of the total average consumption. In another analysis, it was possible to conclude that the HVAC, lighting and pumping categories represent respectively 18.53%, 17.68% and 14.04% of the total average consumption. The solar photovoltaic project devel-oped indicated as the best option a system with an installed power of 175.05 kWp, an internal rate of return of 23.31%, self-consumption of 92.63% and a 5-year payback.
