Climate Change Impact Costs (KliWaKo)

CLIMATE CHANGE IMPACT COSTS – REASSESSMENT OF BUILDING SYSTEMS

A transformation to sustainable building requires not only research and development of lower-carbon building systems, but also their application in practice. Currently, builders decide mainly on the basis of direct manufacturing and construction costs, which makes novel, sustainable building systems less competitive. However, a future-oriented, sustainable economic assessment should also consider indirect costs, such as the impact of CO₂ on climate change and the resulting societal costs.

The project aims to carry out a comprehensive economic assessment of building systems (such as wood, reinforced concrete, steel, wood hybrid, clay, recycled concrete) taking into account the projected social consequences of climate change. A particular focus is on hybrid constructions of natural origin, minimising new building sites and prioritising existing areas. The aim is to use building materials in a resource-efficient manner and to replace conventional building materials with natural building products in order to achieve both economic and ecological objectives and to meet the climate protection objectives. The project will provide an initial assessment of the climate change impact costs of climate-optimised building systems and develop recommendations for action on how these costs can be implemented in the decision-making processes of builders, in particular the public sector.
