International Seminar «Materials for the XXI Century» MCAS

International Seminar «Flows and Linkages: Materials and Products for the 21st Century» MCAS

The proposed seminar is focused on exposing and discussing the latest international advances in technologies and tools aimed at contributing to the reduction of the carbon footprint currently produced by the building construction sector, trying to advance as far as possible towards the double ecological and digital transition of the building activity.

Based on the objectives set out in the international Paris Agreement – i.e. to ensure that the average increase in global temperature does not exceed 1.5ºC with respect to pre-industrial values – and in the European Green Deal – i.e. to achieve the objective of a decarbonised Europe by 2050 – the seminar will explore the problem of decarbonisation of the construction sector from a triple perspective:

1) from the point of view of technological innovation of materials and products
2) from the point of view of low embodied carbon building design
3) from the point of view of the use of digital tools for impact minimisation

Three reference institutions will be involved in each of these areas: a) Civil Engineering Research and Innovation for Sustainability CERIS. University of Lisbon; b) Sustainable Construction ETH Zurich; and c) Institute of Technology of the Royal Danish Academy in Copenhagen. The seminar aims to exchange knowledge and create the basis for research collaboration between the University of Seville and these prestigious institutions.

Presentation of the Preliminary Seminar
Dr. Reyes Rodríguez García, Dr. Carlos Tapia Martín

16.30 h – 18.30 h
On the Oriented Object and the new materialisms.

Dr. Carlos Tapia 
Contemporary philosophy can be divided (very roughly) between a diverse set of thinkers whose focus is on problems of the subject (such as those questions linked to ideology, language and social praxis) such as Ranciere or Zizek, and a group – much less numerous and less published – whose interest lies in defining a philosophical realism that can transcend any philosophy centred on consciousness, experience, action or existence; a philosophy for an after-finitude (the title of a book by Quentin Meillassoux) that is objectualist, which would be a moniker applicable to thinkers such as Latour and De Landa, within a modern tradition that includes a certain part of Heidegger’s production and that of North Whitehead. In this context, one of its founders – Graham Harman – proposed the expression OOO (Oriented Objects Ontology), within his field of installation, which he calls speculative realism and which aims to analyse the relationship between real objects and intentional objects (which we could qualify as projected) and/or sensible objects (which we could define as any objectology with an aesthetic-communicative will). Although these thinkers accept that the intentional object is subsidiary to the real object with which it tries to establish relations, it would seem that deepening such a real-intentional relation comprises a substantive part of the OOO programme.

19.00 – 21.00
Materiality: The Construction of a Perception.

Dr. José Luis Bezos Alonso

The term materiality associated with the architectural project implies understanding and highlighting the organoleptic, haptic and sensory capacities that the use of material has in the construction of space and in its perception. This conception goes beyond the material when it is understood as an element whose only technical properties or functional requirements are taken into account. From this approach, and with an intentionally holistic, inclusive and generic vision, the exhibition develops this look around materiality from eleven different angles or approaches that highlight the importance of the features of materials and their contribution to the construction of an atmosphere and an appearance that defines the personality of the space. It deals with the construction, in short, of a perception that verifies and integrates a fundamental association: the one between material and space.

Keywords: Materiality, material, space, perception, local dynamics.

Climate neutral and circular built environment – right here, right now –

Dr. Guillaume Habert

The IPCC recommends reaching carbon neutrality in the next 20 years. The challenge seems gigantic, and to be honest, out of reach when the built environment represents 40% of greenhouse gas emissions. However, I believe, buildings and infrastructure should no longer be considered as a problem, but as a gigantic opportunity. They can store carbon emissions and counteract climate change. They also serve as storage for materials that can later be mined. And instead of reducing air quality, buildings can actually increase it thanks to natural clay plaster.

It’s possible to build, right here, right now, climate neutral and circular buildings from year one of construction. CO2 emissions from concrete can be reduced by more than 50% when all stakeholders are engaged, from the cement producers, to concrete manufacturers, structural engineers, architects, demolition companies and waste managers… and rather than oppose massive and lightweight construction we can find synergies where a biobased façade made out of timber framed strawbale is directly compensating the CO2 emissions from the optimised low carbon concrete structure.

It is through the appropriate combination of materials and technologies and the synergies between actors that we can achieve climate neutral and circular buildings within such a short period of time. To do so, no material war but rather the promotion of a good material diet. No time to wait for the silver bullet that will save us all. It doesn’t exist… or if it does, it will arrive too late.


12.00 h – 14.00 h
Design for Climate Change
Dr. Emanuele Naboni.

The built environment contributes greatly to climate change and the increase of temperature which is linked to several feedback loops. Climate change increases the risk of generating localized and large scale abrupt changes leading to degradation of the ecosystem and people’s health. Some consequences are irreversible such as those related to biogeochemical flows and extinction of species. Whereas in the same specific regions of the world there has been a constant attempt on minimizing damage, this is not enough. Given such circumstances, the communication will display a series of digital and 1:1 built design approaches to climate change. These are thermal resilient and carbon positive examples of achieving a favourable microclimate in future projections, sustaining an ecologically regenerative, and salutogenic, approach.

Keywords: climate change, thermal resiliency, ecology, carbon positive, human health, digital design, 1:1 prototype


16.00 h – 17.30 h
Products and Systems for the 21st century
Dr. Reyes Rodríguez García and Dr. Angela Barrios Padura

The conference pivots between the knowledge and the need to criticise the different materials most commonly used in construction. Two converging points of view are proposed. First, the various degrees of action (presented as levels of knowledge) are shown, from a minimum knowledge acquired through training to the highest attainable level in which, in each project, innovative solutions are investigated and provided.

Second, the groups of materials and products are shown by a classification based on the degree of manipulation and energy needs of each group, which makes it possible to study them from a more environmental dimension than those proposed with traditional study strategies. The materials with the lowest energy consumption and the lowest ecological impact, classified as natural materials, will be studied in depth.

18.00 h – 20.00 h
Innovative Materials
Dr. Guillaume Habert.
In a second presentation, the objective is to dig into more details about the solutions we will need to implement if we want to achieve a just and climate neutral built environment.

This requires for sure a transformation of our current practices as it is obvious that what we are doing now has deleterious impact on the planet as well as on societal cohesion. But in this presentation, we will show that new practices implemented massively (which is the definition of innovation) don’t necessarily mean high tech ground-breaking solutions. Indeed, vernacular technique readapted to our current context in order to make them viable economically and still environmentally friendly can provide grounded solutions.

We will explore how grounded construction techniques with earth, bamboo, grass and other local matter could look like. Fundamentally, we will show that all these elements can be summarized into fibres, grains and a binder and will then be controlled by general physical principles allowing to transfer a global knowledge and adapt it to local material availability and socio-technical context. Think global but act local could be the summary for a grounded but innovative material. Rather than providing an endless of solution, the presentation will illustrate a general methodology, through some specific examples. To conclude we will question the position of robotic fabrication within this sustainability targets and propose options where indeed low carbon materials are merged with digital fabrication.

9.00 h – 11.00 h
Circular Climate Workshop I. Building a 1:1 Carbon Positive and Nature-Based
Design Climate Change in Sevilla. Design with Upcycling. Leverage Nature-Based Solutions 

Dr. Emanuele Naboni

Designers are now aware – and maybe the first generation to be aware – of the global impact that the built environment contributes to climate change, localized abrupt temperature changes, and degradation of the ecosystem with irreversible consequences affecting the ecosystem and health.

The challenge of rethinking design for such complexity is taken in this short Circular Climate Workshop. The workshop envisions the sketching of a 1:1 prototype in Sevilla able to capitalize on climate change dynamics to re-establish a positive microclimate, decarbonization and link between new bio and technical flows.

Attending students will be able to design local microclimates by capitalizing on forms defined by the metabolism of nature-based solutions, recycled and upscaled materials.

11.30 h – 13.30 h
Sustainable Building Materials
Dr. José Silvestre

The construction, use and rehabilitation of buildings generate substantial environmental impacts, namely due to the significant consumption of energy resources and environmental emissions. Eco-innovation can support however the reduction of these impacts to mitigate climate change.

In fact, eco-design (ecologic design) of products and the creation of information and stimulus for the efficient use of more ecologic products should be motivated. The implementation of this strategy at a European level is giving rise to the birth of criteria for ecologic purchases (green procurement). The use of this type of criteria in public purchases, in particular, can lead to a positive differentiation of the products that comply with the requirements demanded, and to the implementation of environmental improvements in the production processes of the products with the worst performance.

Available environmental databases of environmental impacts of construction products at an international level include: Environmental Product Declarations (EPD) registration systems with site-specific data from each producer; generic databases developed for specific regional contexts; research studies for innovative construction materials.

Researchers from the PositiveCycle group from CERIS (Civil Engineering Research and Innovation for Sustainability) centre at Instituto Superior Técnico – Universidade de Lisboa, Portugal, already made important contributions for the body of knowledge related with Eco-innovation in product development, including thermal insulation materials, construction materials with recycled content, and composite and bio-based construction products. This lecture will present some of these results, and available data at the international level for the sustainability assessment of buildings and other construction works.

Keywords: Eco-innovation, environmental impacts, costs, multi-criteria analysis, building materials.

16.00 h – 17.30 h
Life Cycle Assessment of Construction Materials
Dr. José Silvestre

LCA is an important tool to identify, quantify and prevent environmental impacts over the life cycle of buildings. The application of LCA to the construction materials’ industries makes manufacturers look at the processes from the production stage until the end-of-life of a product, and acknowledge and reduce their global environmental, social and/or economic impacts. Besides improving their processes, manufacturers are also challenged to choose more sustainable raw materials and energy sources, to reduce transport distance, and to improve their products’ performance at installation, during operation and at end-of-life.

The application of environmental (LCA) and economic (or LCC) LCA to Construction are methodologies recognized and standardized at the European level, which are becoming more and more important, and which are being increasingly used in this sector. The LC paradigm emerges, and construction materials and buildings now represent the sum of all impacts and costs in the respective LC (no longer seen as an individual impact and cost).

The application of a detailed LCA approach to construction works is a complex, onerous and extensive task. This also happens because of the quantity of products and processes included in this industry, the long-life cycle of these products when finished, the different service life of the components of the building and the dynamic that differentiates buildings from other standard industrial products, namely during execution, use and end-of-life phases.

This lecture will focus on the Environmental LCA methodology, and on how it can support eco-innovation, circular economy, thermal retrofit of buildings and construction digitalization.

Keywords: Life Cycle Assessment, environmental impacts, construction, life cycle costs, buildings.

16.00 h – 18.30 h
Ecolabels and environmental declarations
Dr. Ángela Barrios Padura and Dr. Reyes Rodríguez Garcia

The Ecolabels of construction materials help us certify the sustainability of architectural interventions. They are the guarantee of the limitation of negative impacts on the environment and people of construction products, and of the communication of environmental information by companies. To Acquire knowledge about the European directives on environmental labelling is essential to understand the scope of the guarantees and prescribe or recommend among producers those that demonstrate better environmental performance. In the seminar, a critical analysis of eco-labels and environmental declarations of construction products will be carried out, in order to train students in decision-making in sustainable construction processes. In addition to, it will insist on the need to know and characterize the various materials and products from the knowledge of their composition and manufacturing processes, to carry out more appropriate decisions from an ecological point of view.

Key words: Ecolabel, environmental declaration, construction materials, sustainable construction.

19.00 h – 20.30 h
Present and future of construction materials
Dr. Reyes Rodríguez García

This conference will be a corollary to the seminar, prior to the conclusions. It will present the most relevant observations from the panel discussions and colloquiums, as well as the interventions most closely linked to the applications and properties of the materials and products.

The aim is also to propose the most appropriate strategies and provide an environment in which to define ways of doing things and, above all, ways of moving forward with
