Two significant challenges in future-proofing the sector are the needs to substantially reduce resource use together with embodied and whole life carbon emissions, particularly of new buildings, through both industry decarbonization measures as well as effective building design strategies and related policy frameworks. Here, we present the Global Building Data Initiative (GBDI), set up for advancing open data to inform action for reducing resource use and upfront embodied carbon of new buildings globally. By empowering decision-makers in industry and policy, GBDI aims to drive decarbonization action for buildings considering a whole life-cycle approach. GBDI and partners developed a coordinated, open, and scalable data protocol as well as the technical infrastructure, a web-based application for global data collection and analysis. In this contribution we present the open building data format (openBDF) and how leading industry organizations are implementing it to improve comparability and advance exchange of WLC data across platforms. Furthermore, we present the global building data hub, an open-source platform for managing and assessing building life cycle data. Since its launch in early 2024, GBDI has positioned itself amongst the leading initiatives driving open data on whole life carbon of buildings as a means for assessing and reducing life cycle emissions of new construction globally. GBDI now proceeds to compile and assess, aiming to establish a global building dataset comprising information on at least 10.000 buildings. The insights from these data will be used to inform the setting reduction targets and context-specific reference decarbonization pathways.

Additionally, a transition from prescriptive to performance specifications must occur. As examples, concerns with tests such as the loss on ignition and strength activity index have led to the development of tests such as the foam index test and the R3 tests. However, these new tests are only beginning to be included in standard specifications and the user community will need to develop familiarity with a performance-based approach to specifying materials. In this talk, integration of new tests are discussed. An overview of new standards and specifications in progress is presented, including new performance-based specifications.

Speaker: Anupama V.A, Indian Institute of Technology Madras, India Title: Understanding Salt Weathering in Combined Brick-Mortar Masonry Systems Salt weathering poses a substantial threat to India's architectural heritage, particularly affecting coastal monuments built predominantly from brick masonry. This deterioration process impacts both the aesthetics and durability of these structures, as they are continually exposed to a dynamic environment characterized by fluctuations in moisture, temperature, salinity, wind, and humidity, all of which accelerate their decay. Beyond mechanical damage through wear and tear, the porous materials of these buildings are susceptible to chemical effects like dissolution, hydrolysis, and the damaging cycles of salt crystallization precipitated by repeated episodes of moisture ingress and evaporation. Salt crystallization, in particular, has been identified as highly detrimental, with the capacity to inflict damage that penetrates beyond the superficial layer, compromising material cohesion and structural integrity. This deep-seated damage necessitates focused research to develop effective conservation methods that ensure the longevity and functionality of heritage structures. Conservation efforts prioritize the selection of repair materials that not only support the structural integrity but are also compatible with the original materials to preserve historical authenticity. In laboratory settings, accelerated weathering cycles that alternate between wetting and drying are utilized to simulate real-world environmental conditions. These tests are crucial for evaluating the durability of different substrates and mortar compositions under salt exposure. This talk specifically investigates the performance of bricks and mortar formulations, exploring both individual and combined responses to these simulated salt weathering cycles. It also considers the impact of wind on their durability. The research methodically examines the resilience of both composite brick-mortar samples and individual specimens of bricks and various mortars composed of cement, hydrated lime, fly ash, and limestone. Following a systematic weathering protocol, the study assesses their resistance to salt damage, monitoring mass changes throughout the cycles and conducting comprehensive physicomechanical, microstructural, mineralogical, and morphological characterizations to gauge their salt weathering resistance.

Speaker: Kirushnapillai Kopitha, PhD Student, Swinburne University of Technology Title: Towards amine-based CO2 capture in cement-based materials This research aims to enhance CO2 sequestration in cement-based materials by integrating amines, which are organic compounds with nitrogen atoms capable of bonding with CO2. The study examines how these amines improve CO2 capture within essential hydrated phases like portlandite and Calcium-Silicate-Hydrate (C-S-H). Findings indicate that amines significantly accelerate CO2 mineralisation, leading to notable microstructural changes and increased calcite formation. By advancing the development of sustainable construction materials, this work positions buildings to function as "synthetic trees," offering an innovative approach to reducing atmospheric CO2 and mitigating global warming.
