Resumo O design biofílico proporciona soluções de integração da natureza com os ambientes construídos, promovendo agradabilidade (pleasantness) e bem-estar para os usuários. Este trabalho tem como objetivo identificar emoções positivas dos usuários, associadas aos atributos do design biofílico na avaliação do ambiente construído do novo campus Unisinos, em Porto Alegre. O método proposto abrange uma etapa qualitativa e outra quantitativa, partindo da pesquisa de satisfação com os usuários. Por meio da estruturação de questionário, são aferidas maiores informações a respeito das emoções positivas elicitadas pelos atributos da edificação, assim como da intensidade em que essas emoções são percebidas pelos alunos na interação com o espaço. Os resultados demonstram a contribuição positiva do campo de estudo do design e emoção, bem como do design biofílico, para avaliação do ambiente construído.

Abstract Biophilic design has brought nature integration solutions with built-in environments, promoting pleasantness and well-being for users. This paper aims to identify users’ positive emotions associated to the attributes of biophilic design in the evaluation of the built environment of the new Unisinos campus, in Porto Alegre. The proposed method includes a qualitative and a quantitative step, starting with satisfaction survey with the users. A questionnaire was developed to gain more information about the positive emotions elicited by the attributes of the building and the intensity by which those attributes are perceived by the students in interaction with the space. The results demonstrate the positive contribution of the study of design and emotion, as well as biophilic design, to evaluate the built environment.

ABSTRACT Concerns for the environment are recurrent in our society, and research on low impact materials such as those produced from waste is an alternative. This work is based on the reuse of scrap paper and rice hulls aiming to increase the life cycle of these waste products and to find better destination. Composites with a volumetric filler content (dispersed phase) of 80% were produced via compression molding using polyurethane (PU) based on castor oil or polyester resin as matrix, in four distinct families: polyester/rice hulls, PU/rice hulls, polyester/paper and PU/paper. The following tests were performed: water sorption, contact angle, hardness, impact and tensile testing. Scanning electron microscopy (SEM) was used for fracture morphology study. Basic visual analysis showed greater void content for the rice hull composites, making them less aesthetically appealing compared to paper. It was observed in the case of PU matrix the filler greatly influenced the rigidity since this pure material was more flexible compared to pure polyester. Filler incorporation decreased tensile strength of the polyester matrix but significantly increased that of the PU matrix.

ABSTRACT This study aimed to analyze the waterproofing MDF with different coatings. For this, a comparative study was conducted with the following coatings on MDF: Vegetable polyurethane resin on castor oil-based, acrylic lacquer and marine varnish. To carry out the research, sewed up the samples in sequence, they received the coatings, and then we performed the test water absorption. As a result, the polyurethane resin to castor oil-based coating was presented the best results, that is, lower levels of water absorption lower thickness swelling and volume. Finally, it is believed that the study of waterproofing MDF plant originated from polyurethane castor oil is beneficial because it is a renewable source of material.
