Local resources, traditional construction methods and sustainable materials are crucial for ecological development in the construction sector. In order to utilise this valuable knowledge for modern construction projects, a database has been developed that provides information on local resources, materials and traditional techniques.

Material
Concrete
Short description
Concrete is a versatile building material made of cement, water, aggregates, and often additives. It is moldable, hardens over time, and is widely used in the construction industry, especially for bridges, roads, flood protection structures, and buildings. In the Danube region, concrete is frequently used for construction projects due to the availability of raw materials like gravel and sand along the Danube.
How does it support the green transformation?
Concrete can support the green transformation in the Danube region in various ways. By developing more sustainable types of concrete, such as CO2-reduced concrete or recycled concrete, the environmental impact can be reduced. In addition, innovative construction methods such as the integration of plants or photovoltaic systems in concrete surfaces can improve energy efficiency and biodiversity. Concrete can also be used in infrastructure to strengthen flood protection, which is particularly important in regions along the Danube in order to better cope with climate-related extreme events.

Tool
The Cradle-to-Cradle toolbox
Short description
The Cradle-to-Cradle toolbox developed by the Cradle ALP project will encompass a series of tools enabling business support organisations and businesses to better implement a circular transformation along the entire value chain, from product design until end of life valorisation.
How does it support the green transformation?
The Cradle-to-Cradle toolbox will encompass a series of tools enabling business support organisations and businesses to better implement a circular transformation along the entire value chain, from product design until end of life valorisation. Examples of tools are: Value proposition canvas, business model development, capacity and technology maturity assessment, roadmap development and business model canvas, value chain generator.
Digital Twin
Short description
A digital twin is a digital replica of a physical object or system that evaluates and simulates data in real time. In the context of the green transformation in the construction sector, this technology can play a central role by promoting sustainability and resource efficiency.
How does it support the green transformation?
A Digital Twin is a powerful tool for driving the green transformation of the construction sector. From planning to construction, operation, and material reuse, this technology can conserve resources, reduce emissions, and extend the lifecycle of buildings. Integrating Digital Twins into the construction industry will not only improve sustainability but also enhance efficiency and reduce costs in the long run.
METABULDING Labs Platform
Short description
EU wide network of Testing facilities & Innovation services for new building envelope technologies & products
How does it support the green transformation?
It serves as a Virtual Single-Entry Point, giving access to a powerful innovation ecosystem, including a wide network of testing facilities: Laboratories / Test Benches Pilot Buildings / Living Labs allowing stakeholders to develop and test innovative systems and solutions for next generation buildings
The Multi-Criteria Decision Support System (MCDSS)
Short description
Innovative tool designed to help forestry stakeholders make informed, long-term strategic decisions tailored to their specific objectives
How does it support the green transformation?
A multi-criteria decision support system that will assess sustainable forest management, synergies and trade-offs between forest ecosystem services, reliable wood supply and stakeholder interests based on indicators for the forest-wood value chain, taking into account social, economic and environmental dimensions, thereby facilitating decision making.
Steel
Short description
Steel is a solid metal made of iron and carbon, known for its strength and durability. In the Danube region, steel is mainly used in construction, for bridges, infrastructure projects, and mechanical engineering.
How does it support the green transformation?
Steel can support the green transformation by being produced through more environmentally friendly processes, such as using hydrogen instead of carbon for iron reduction. Additionally, recycled steel can be used to conserve resources and reduce energy consumption. Steel is durable and recyclable, making it an important material for sustainable construction projects, renewable energy, and the development of eco-friendly infrastructure.

Material
Wood
Short description
Wood is a natural, sustainable building material that is light, robust and versatile. It is widely used in the construction sector in the Danube region for building houses, bridges and interiors, especially in regions with abundant forest resources.
How does it support the green transformation?
Wood can support the green transformation in the Danube region, as it is a renewable, CO2-storing building material. Its use reduces the need for more energy-intensive materials such as concrete and steel. Wood enables sustainable construction and promotes a circular economy through reuse and recycling. In addition, the regional timber industry supports jobs and short transport routes, which further reduces the environmental impact.
