ResumenEl diseño de los marcos de aluminio en muros cortina modulares podría ser más eficiente estructuralmente y térmicamente: se podría aprovechar la rigidez de los vidrios para reducir la profundidad estructural y se podrían emplear materiales de menor conductividad térmica que el aluminio. Estas propuestas se han aplicado en el desarrollo de un sistema de muro cortina alternativo en el cual se emplean adhesivos para adherir los montantes al vidrio y conseguir un panel compuesto de gran rigidez. Esto permite reducir la profundidad de los montantes e integralos en el plano del vidrio. La tranmisión térmica se reduce sustituyendo el aluminio por polímeros reforzados de fibra de vidrio. En este artículo se describe el sistema propuesto y se compara su comportamiento térmico con el de un sistema tradicional a través de cálculo analítico y numérico.Palabras clave: Muro cortina; marco; térmico.
AbstractFraming of unitized curtain walls is dimensioned to carry wind load without taking advantage of potential composite contribution of glass. Subsequently, it is unnecessarily deep, occupying valuable space, and protrudes to the inside, causing visual disruption. Moreover, it is generally made of high thermal conductivity metal alloys, contributing to substantial thermal transmission at joints. An innovative frame-integrated unitised curtain wall has been developed that, compared to conventional systems, reduces structural depth significantly, allows an inside flush finish and reduces thermal transmission at joints. The idea is to adhesively bond a Glass Fibre Reinforced Polymer (GFRP) frame to the edge of the Insulated Glass Unit (IGU), thereby achieving low thermal transmittance and composite structural behaviour. The frame is to fit within the glazing cavity depth. This paper provides a description of the proposed system and assesses its thermal transmittance and risk of condensation through comparative analytical and numerical thermal analysis with a conventional system taken as reference.
Sustainable spaces are those that are optimized, accessible, promote user experience and aim to reduce CO2 emissions while enhancing users’ well-being and comfort. The purpose of this paper is to present a methodology that was developed during the COVID-19 pandemic to understand and improve the use of coliving spaces based on remote Post-Occupancy Evaluation (POE) analysis of the digital trail generated by the users. Applying the POE methodology based on data collection from IT infrastructure enabled to identify opportunities to improve the future design of human-centered spaces. The residential market, design-wise traditional for centuries, is now facing a high-speed adaptation to the changing needs, accelerated by the COVID-19 crisis. New ways of living and shared spaces like Coliving are escalating. Technology is both an enabler of this shift in housing and the solution to operating and managing these new buildings. This paper demonstrates, through the case study of a Coliving space located in Madrid, Spain, the benefits of implementing data analysis of the digital trail collected from in-built IT systems such as smart locks, Wi-Fi networks and electric consumption devices. The conclusion is that analysing the available data from the digital infrastructure of coliving buildings can enable practitioners to improve the future design of residential spaces.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
