ABSTRACT

This study aimed to create EI Scal, an environmental impact assessment scal, related to construction materials used in the reinforced concrete structure production. The main reason for that was based on the need to classify the environmental impact levels through indicators to assess the damage level process. The scale allowed converting information to estimate the environmental impact caused. Indicators were defined trough the requirements and classification criteria of impact aspects considering the eco-design theory. Moreover, the scale allowed classifying the materials and processes environmental impact through four score categories which resulted in a single final impact score. It was concluded that the EI scale could be cheap, accessible, and relevant tool for environmental impact controlling and reduction, allowing the planning and material specification to minimize the construction negative effects caused in the environment.

ABSTRACT

Tem como objetivo estimar a funçäo demanda residencial por água para o município de Londrina. Discute a regulaçäo do uso da água bruta no país e no estado do Paraná. Afirma que os resultados obtidos levam a inferir que há um amplo campo de pesquisa na área de regulaçäo do uso da água. Acredita que apenas uma legislaçäo abrangente e bem definida näo é garantia de uma regulaçäo eficiente. Verifica que o aumento do preço da água interferirá no consumo de todas as classes de renda analisadas. Observa que a reduçäo do volume de água demandado pelos usuários afetará a receita total da companhia prestadora de serviços, bem como seus custos de produçäo.
