The building industry has a significant impact on the environment and without great transformations on both design strategies and building techniques the world climate ambitions will be compromised. According to the World Green Building Council, building and construction are responsible for 39% of all carbon emissions in the world.
We believe that to address this issue there we must considered two combined paths. New technologies of digital fabrication applied to the use of natural materials.

Build: from high to low tech is an international congress focused on how the construction industry must adjust to the impact it brings on the environment. We focus on built examples of worldwide buildings where natural materials with high embodied carbon are applied and also new digital fabrication techniques used in order to maximize material usage and waste reduction. We gathered participants from around the world, from Indonesia to Paraguay, with a diverse background that are able to give us a broad vision and solutions of this. The next edition will evolve to a meeting point between architects and material developers to promote workshops complementary to the public talks.
Sustainability
Biogenic Materials
Embodied Carbon
Digital Fabrication
Reuse
The key objectives of our initiative are to publicize and promote the use of Biogenic Materials and Digital Fabrication in the construction industry. Several studies indicate that the built environment is responsible for something between 35% to 45% of the global Co2 emissions. At the current pace if the industry doesn't shift it's focus from oil based materials to biogenic materials it will be impossible to meet the world environmental goals. We are aware that some materials will be unavoidable and that's why it is also indispensable to apply new technologies like the Digital Fabrication in order to optimize material usage and to reduce waste. Our initiative had the specific Portuguese context in mind where the construction industry continues to show high resistance to changes in the established processes regarding construction techniques and new material usages. This is why we decided to invite international renowned specialists that could share their personal experience working with this type of materials and techniques, showing the local community that it is possible to build different and better.
For the next edition the event will move forward in order to gather material producers and promote workshops where people can actually try and experiment with the materials.
Regarding aesthetics and quality of experience there are two different angles.
The first is the technical advantages of the biogenic materials, besides the embodied carbon most of them are extremely effective to introduce thermal comfort, acoustic comfort and also natural humidity control. The fact that a simple material change can promote better interior air quality without the use of mechanical means represent and great improvement to the industry, not only on the production side but also on during the life of the building. Reducing the energy consumption is a key aspect to avoid the rebounding effect of increasing energy use after providing buildings with better insulation.
The second angle is the curatorship of the speakers. One key aspect beside that the building examples must be built is also their undeniable design quality. It's common that buildings that promote ecological approaches are usually so focused on the technical side of the problem that they neglect the general aesthetic. We invited world awarded guests who are able to design beautiful building and address climate issues, solving the problem thru design and promoting better built environments.
One of our main priorities of our initiative is to show a diverse range of contexts. Most of the discussion about the impact of construction on the environment is centered in the western world buildings but the reality is that the territories where we'll see the biggest raise on cities population and construction growth on the following years is in Asia and Africa.
This is why we invited to participate in our first event Yasmeen Lari from Pakistan who talked about her Barefood Social Architecture which calls for urgent solutions on the Least Developed Countries, Wael al Awar from UAE who talked about the impact of desalinization of the water and how we must find a solution for the by byproduct of this process, Minímo Comun from Paraguay or Elora Hardy from Indonesia. We wanted to prove that this kind of solution can be made in Germany or Switzerland but also in harder contexts like Asia or South America.
The built environment is the common ground we hall share. Cities and buildings are the places where societies exchange ideas and construct the future. We strongly believe that the quality of the spaces we inhabit strongly reflect on it's users. This is why we propose a shift to Biogenic Materials, which are able to connect us to earth and it's natural resources at the same time that they provide us a healthier environment to live.
Architecture is a slow process with long lasting impact on the world. In the next 5 years we will build thousands of buildings that will last for 100 or 200 years. It's urgent that we change our approach to construction if we want to improve our legacy for future generations, the buildings will exist, it's up to us to build them better.
For the first edition we had several regional stakeholder involved as institutional partners, such as the Northern Chapter of the Portuguese Architects Association and Porto Municipality. Their contribute was mainly regarding the divulgation of the event. And was financed by a Portugal 2020.
The main knowledge field was architecture. The diversity of the representatives allowed us to have an approach from different fields.
Aris Kafantaris, project manager of Kengo Kuma and Associates explained how the office organizes it's production;
Claudia Pasquero e Marco Poletto founders of ecoLogicStudio described their research about the use of algae in construction;
Elora Hardy, founder of Indonesian Studio IBUKU demonstrated the constructive capacities of bambu;
Fabio Gramazio, founder of the first world digital fabrication lab at ETH Zurich, shared is research about digital process on construction;
Gilles Retsin, co-founder of AUAR Labs shared its research about pre-fab as a way to solve housing shortage;
Hans Drexler, founder of DGJ Architektur, showed us how the office reduces active means and replaces them with passive ones;
Lin Lifeng, founder of Lin Architecture, shared his experience working in China rural context;
Luca Compri, founder of LCA architetti, offered a global vision of his work applying natural materials;
Michael Burchert, professor of sustainability at BAUWENDE talked about the use of straw as insulation;
Seryo Merlo, co-founder of Mínimo Común shared his experience in Paraguay;
Paloma Gormley, co-founder of Material Culture shared their research about biogenic materials in UK;
Sonia Sifflet, partner of Lemoal Lemoal talked about the use of hempcrete block for the first time on a French public building;
Valentina Porceddu from MC A talked about a 3d printed house using raw earth;
Wael al Awar founder of waiwai talk about he use of salt to make a Portland cement substitute;
Yasmeen Lari from the Heritage Foundation of Pakistan shares her Barefoot Social Architecture Method.
On the particular case of Portugal this was the first event ever dedicated to this theme that managed to gather a broad panel of experienced contributes, specially focused on built examples. Because the local industry is still showing some resistance the change, the events related to building sustainability are usually focused on academic contributions. This was the first time that there was an event focused on implemented solutions. We intend to keep this innovative aspect by inviting international renowned architects to share their experiences.
Our initiative is completely replicated or transferred in any context of the world because this event model is universal and the aim is to always invite people from different contexts. If we change location the only difference will be the place where we do it, but the content will always apply.
Our approach is based on a extensive research about the leaded of the field. After a broad selection we organized them by themes, Natural Materials and Digital Fabrication. After this we manage to get the final list and organize the event.
The challenge of the building industry is a global issue. With our local event we try to promote better solution, although it's located in Portugal we had a live streaming online that allowed us to have spectator from all over the world. We hope people get inspired by our guest and start designing better on their daily practice.
The first edition of the international congress created a legacy, specially thru the book published after. The book is being distributed to all the world and we also created an online platform with all the videos from the event to inspire people all over the world.
The successful result of the initiative is that we were invited to organize the next edition on September 2023.
The change of the construction industry to adapt to new materials and technologies will have a huge impact on the competences of the current professionals. This challenges will demand a transition to a greener framework.
