It is essential that the society understands the importance of sustainable development, its implication for the existing living standards and the need to implement management policies that promote sustainability. Rehabilitation assumes a fundamental role in this process; however, we are faced with the lack of specific, adequate and simplified tools for the sustainability assessment in rehabilitation actions. In this paper, the analysis of different sustainability assessment systems was conducted, comparing them in order to identify the adjustments to be made to a Portuguese model taken under consideration. Subsequently, the model was cross-checked with current European and national urban rehabilitation and regeneration policies, analysing their contribution to sustainability, in order to define the assessment criteria and create a Simplified Method for the Sustainability Assessment for rehabilitation in old urban centres, which can be a useful tool, easy to use by all actors in the process and as a way of preserving the history of this areas, and the memory of those who inhabit them. This Method considers five major areas: Water, Energy, Materials, Emissions and Cultural, Economic and Social Environments. For each of these criteria, measurement indicators and levels of assessment were settled, adjusted to the context of old urban centres.

Através de alguns exemplos práticos, pretende-se defender que o conhecimento geométrico e, em particular, o conhecimento das curvas cónicas e suas aplicações, pode potenciar o trabalho projetual dos designers, diminuir os custos de hardware e software no ensino e no trabalho profissional, diminuir a necessidade de recurso a meios sofisticados e caros, reduzir a necessidade de permanente atualização dos meios tecnológicos, e de utilização de software que implique formação especializada e, sobretudo, que necessite de longos períodos de formação. Temos em vista contribuir para o reconhecimento da importância do estudo destas curvas e das superfícies por elas geradas, em especial no ensino da Geometria em cursos de Design. De facto, a partir da sistematização do conhecimento existente em outras áreas, como, por exemplo, a arquitetura e as engenharias, pelo aprofundamento da adaptação de propriedades das cónicas e de conhecimentos de áreas, como a geometria analítica ou a projetiva para a linguagem dos traçados geométricos, e pela contribuição com a sugestão de novos traçados, pode desenvolver-se a capacidade dos designers e estudantes de design resolverem problemas, no âmbito do projeto, na representação técnica e na comunicação externa com não peritos.

Brand Visual Identity is an identification system that, with flexibility, ensures the unity and coherence of visual communication (in multiple media: physical as products, objects, or graphics; architectural and ambiance; audio-visual; digital and virtual). Brand Marks occupy a top place in the good performance of most Brand Visual Identity systems, even when these rely more on imagery and use Brand Marks with less expressiveness. In dynamic Visual Identity systems, the Brand Marks may constitute themselves as systems within the Brand Visual Identity supersystem. This study aims to dissect existing brand marks, focusing on how the graphic components (symbol, logotype) are designed, prioritised, and correlated to achieve differentiation, contrast, recognition, and memorisation. This include an empirical examination based on direct observation and exploration and in survey by questionnaire with a sample of 400 participants, aiming at the definition of design principles to aid the design of Brand Marks and to be considered in the definition of the “map of competitors” tool, which intends to aid in the analysis of multiple visual identities competing in the same market or segment.
