The awareness of the environmental impact of buildings during their entire whole life cycle has seen a growing interest in recent years. In fact, as buildings become more energy-efficient, life cycle impacts become increasingly important. Investors in the building sector are becoming aware of the direct and indirect benefits of a design process that enables the control of the impact of the building, ensuring the higher quality, intrinsic value of materials under a circular economy point of view. The durability is, together with reusability and recyclability, one of the main characteristics of construction materials. In this framework, the purpose of this paper is to describe a BIM-based approach to life cycle assessment (LCA) from the initial stages of the design of the Socrates Building in Viladecans. For this scope, a digital model in the TCQi GMA software was created to assist in the evaluation, optimization, and comparison of different design and construction alternatives. An integrated project delivery contract was adopted. These aspects altogether showed the potential of increasing the real estate value and the profitability of the building. This paper discusses problems that emerged during the digital project management, assessing criticalities and opportunities.

RESUMENEl presente artículo analiza diversas celosías cerámicas, realizadas por el equipo de arquitectura Pich-Aguilera en colaboración con diversas industrias, tratando de ilustrar particularidades en su comportamiento ambiental y su desarrollo tecnológico.Mediante dicho análisis el trabajo trata de reflexionar sobre el sistema constructivo de la celosía cerámica como el resultado de la combinación de componentes y sistemas cerámicos muy diversos, implementados a lo largo del tiempo en distintas tipologías constructivas y funcionales. Paralelamente el estudio apunta algunas hipótesis acerca de las invariantes esenciales del propio sistema y de posibles evoluciones futuras.Palabras clave: celosía cerámica; comportamiento ambiental; desarrollo tecnológico; producción industrial. ABSTRACT This paper analyzes several ceramic lattices, designed and developed by the architectural firm Picharchitects together with different industries. The paper tries to point out some of this construction system's particularities in relation with its environmental behavior and technological development.At the same time the paper introduces some reflections about the lattices as a combination of different and diverse components that have been implemented along several construction technics and architectural functionalities. Moreover the paper tries to introduce some hypothesis about the construction system invariabilities (as an essences of the system itself) and some of its possible evolutions.
