Climate-proof and resource efficient building requires new construction solutions and collaboration between governments, organizations in the construction sector and knowledge institutions. This work package is the social impact of various building solutions (including emerging technologies) over the life cycle transparent, as input for a sound business case.
This work package is organized against three different conceptual levels that differ in scale, stakeholders, and investment related questions:
The first level targets difficult soil conditions and its relevance for city planning and design for new construction assignments and for large redevelopments. Due to a growing population, cities are being developed on land with poor soil condition. Improper design and planning results in all kinds of problems that are costly, poor in resource efficiency, and vulnerable for climate change. Chapter 2 describes these issues and gives an inventory of technologies and assessment models that can be used.
The next level targets the main material flow for buildings and infrastructures, being mineral building materials. Besides that fact that this is the largest material flow for the construction of buildings and infrastructures (both in resource need as well in waste), mineral building materials are also dominant in the ‘hard surface’ in cities (that is relevant for potential impact of heat and rainfall). The building envelope (façade and roof) is also a great influence on the energy efficiency of a building. Chapter 3 describes circular economy for mineral building materials, and what technologies and methods are available to design products that contribute to climate resilient cities.
The last level targets roofs. Roofs are a building component that impact the building itself as well as the area. Chapter 4 describes the differentiating roof top solutions, what the impact is and how tools to assess impacts can be used for decision making on roof top investments.
The last chapter, chapter 5, describes ‘cases’ where investments in buildings and infrastructure are made, or have to be made, and where the knowledge that is combined in this contribute may be useful for decision making.
