On Tuesday, October 21,\u00a0Arquitectes per la Sostenibilitat<\/em>\u00a0(AuS<\/a>), together with the\u00a0Col\u00b7legi d\u2019Arquitectes de Catalunya<\/em>\u00a0(COAC<\/a>), the CSCAE<\/a> and the ACE-CAE<\/a>, organized the fourth edition of the conference\u00a0\u201cDecarbonizing Architecture<\/a>\u201d<\/strong>, a key event for discussing the ecological transition of the architectural sector and of great importance for the AuS group.<\/p>\n

Once again presented by meteorologist Francesc Mauri, the conference brought together leading professionals and institutions to share visions and strategies toward a fairer, more responsible, and decarbonized architecture. The opening session featured remarks from Guillem Costa Calsamiglia (COAC), Greta Tresserra (President of AuS), Marta Vall-llossera (CSCAE), Carl B\u00e4ckstrand (ACE-CAE), and I\u00f1aqui Carnicero\u00a0(MIVAU- Ministerio de Vivienda y Agenda Urbana<\/a>).<\/p>\n<\/div><\/div>

One of the most remarkable aspects of this edition was the collective and committed participation of AuS members. The first rows were filled, becoming a true intergenerational meeting point for the group. The new board \u2014Greta Tresserra (President), Jade Serra and Albert Sagrera (Vice Presidents), S\u00f2nia Hern\u00e1ndez-Monta\u00f1o (Secretary), Toni Escud\u00e9 (Treasurer), and board members Bea de Diego, \u00c0ngels Castellarnau, Sander Laudy, Licinio Alfaro, and Marta Galisteo\u2014 played an active role both in the preparation and as speakers, alongside a large number of members. This reinforced the group\u2019s role as a driving force for change within COAC. Their presence symbolizes a shared commitment to decarbonization and to an architecture aligned with climate and social objectives.<\/p>\n<\/div><\/div>

Program<\/h3>\n<\/div><\/div>

Before the sessions began, the conference opened with the keynote lecture\u00a0\u201cThe Climate Emergency in Europe\u201d<\/strong>, delivered by Mar Santamar\u00eda, co-founder of 300.000 Km\/s<\/a>, and Albert Soret from the\u00a0Barcelona Supercomputing Center (BSC)<\/em><\/a>. Their talk provided data and a scientific and forward-looking perspective on the climate crisis across the continent.<\/p>\n<\/div><\/div>

<\/h5>\n
Session 1 \u00b7 Agendas for Change<\/h5>\n

Moderated by Dolores Huerta (GBCe<\/a>), the first session analyzed how decarbonization policies are being integrated with housing access policies, through a strategic and territorial planning perspective. It also addressed instruments of the EPBD and the potential of their transposition at the national level, such as the CTE, the National Renovation Plan, and the Renovation Passport. Participants included Marcos Ros (European Parliament), Albert Cuch\u00ed (former president of AuS), Mar\u00eda Teresa Verd\u00fa (MIVAU), Albert Sagrera, and Joaquim Arcas, current Vice President and member of AuS, respectively. Together, they offered complementary technical and political perspectives on how to make the decarbonization of architecture a reality.<\/p>\n<\/div><\/div>

<\/h5>\n
Session 2 \u00b7 Renovation: Improving Our Lives, Homes, and Cities<\/h5>\n

Moderated by Sandra Bestraten, Barcelona President of the COAC and member of AuS, this session showcased transformative projects such as La Bombeta<\/em>\u00a0(Lacol<\/a> and Societat Org\u00e0nica<\/a>),\u00a0The Cosmopolitan<\/em>\u00a0(&bogdan<\/a>), rural housing renovations in Alt Pirineu (Coop d\u2019Era<\/a>), and the\u00a0Prodis Foundation<\/em><\/a>\u00a0(Harquitectes<\/a>). Each project demonstrated how renovation goes far beyond energy efficiency, contributing to inclusion, health, and quality of life.<\/p>\n<\/div><\/div>

\"\"<\/div><\/div>
<\/h5>\n
Session 3 \u00b7 The \u201cNew\u201d New Construction<\/h5>\n

Moderated by Albert Sagrera, Vice President of AuS, this session presented outstanding practices in biomaterials, circularity, and energy efficiency. Highlights included projects by Jade Serra (Slowstudio<\/a>), Vice President of AuS, together with Jes\u00fas Alonso and Figueras (ALFI biocons SL<\/a>), focusing on bioclimatic design and responsible single-family housing construction. The Hortus Building<\/em>\u00a0and\u00a0Ricola Warehouse<\/em>\u00a0were presented by Alexander Franz (Herzog & de Meuron<\/a>); 17 social housing units featuring local biomaterial innovation by Sara Ferran (taller11<\/em><\/a>); and a talk on circularity by Juan Pablo Herrero (EFFEKT Arkitekter<\/em><\/a>).<\/p>\n
