Based on the three dimensions model of sustainability, different studies that address the integration of the culture and sustainability concepts from a theoretical field propose that culture should be included as another sustainability dimension to a greater degree. This approach has not been put into practice to date. In fact, when sustainability application is examined in cultural activities such as museums and exhibitions, in most cases it is associated with only one dimension and evaluation methodologies based on a holistic approach; the Life Cycle Sustainability Assessment (LCSA) is used in very few cases. In this work, a methodological framework is proposed to add the cultural dimension to the study of the environmental, economic, and social dimensions of sustainability. A sequence of phases in line with the LCSA methodology is used to achieve the simultaneous evaluation of impacts associated with a sustainability approach based on four dimensions. A thorough literature review revealed cultural indicators, which were classified and organized in order to facilitate the cultural impact assessment and complement the indicators already used to evaluate other dimensions. Additionally, the approaches and methods proposed are put into practice in a case study, which consists of an experimental exhibition room. The different phases of the methodology have been successively developed, and indicators for all sustainability dimensions have been obtained. Thus, the theoretical contribution of this work is embellished with the development of a practical case, which demonstrate that cultural dimensions can be evaluated together with the rest of the dimensions in order to obtain a multidimensional assessment of sustainability.

The growing tendency for end users to get involved in the design and manufacturing phase of their own products has led to the proliferation of makers and prosumers. The tools available for this have been adapted to be used by non-specialized users who seek to meet their own needs and wants. Modular design offers a series of advantages directly related to the needs of current users, but which has hardly been used to benefit them. Instead, its development has geared towards aspects that are hidden to the consumer, such as flexible production.This work presents a survey, part of a wider research, whose objective is to develop a methodological model for the prosumer to benefit from modular design. The survey was open for several months and was only aimed at makers, prosumers and designers. A dissemination plan was drawn up where the current communication channels of these users were taken into account. The results show what the current prosumer is like, what their needs are and how they relate to modular design. Finally, the conclusions provide information on how to develop a model proposal to ensure its correct usability and acceptance.

Modular design is the design based on independent and connectable modules to achieve product variety. It is an ideal tool that could facilitate the inclusion of prosumers in the creative process. However, its evolution has focused on product development and not on end users. The creation of a new modular design model for prosumers could respond to their needs while exploiting the advantages of modularity. The present work analyzes the applicability of modular design in the prosumer scope and defines a guideline for the creation of the new model. To this end, prosumer and modular design methods are collected and analyzed throughout the previously defined design process. The intersection between both terms is analyzed through a series of real cases and design methods that show what the objectives of prosumers are and if the present products and methods meet their needs. These results will establish the current and potential link between modular design and prosumers. Finally, the objectives and stages to develop the design model based on previous results are presented. The paper presents relevant findings such as the lack of methods in the conceptual design phases and a guideline to ensure that the prosumer benefits from modular design.

Product design is a process developed by specialized profiles such as designers or engineers. For this reason, most of product design and/or manufacturing methods developed are aimed at experienced professionals. However, in the current social and technological context, we observe that the number ofprosumers, users who partially produce the products they consume, is increasing. These users are involved in design, manufacturing or assembly phases of the product to obtain final results that respond to specific needs and desires. Given this emerging trend, we wonder if there are methodologies focused on these users in particular, both in the academic field and in practice. This work aims to clarify this issue through a review of research papers and real cases. The results obtained differentiate between the methodologies that have been defined in the academic field and those that have not been compiled but whose repeated use has agreed its application and existence in practice. The methodologies identified are analyzed in two tables that summarize how they are applied and what their main objective is. The results and conclusions offer both the scientific community and the prosumers a series of product design and manufacturing methods focused on non-specialized profiles.
