“De woningcrisis biedt kansen. De kans om een duurzaam en langdurig gezond woonklimaat te realiseren.”

Woningnood is geen nieuw verschijnsel in ons land. Al in de negentiende eeuw leidde snelle bevolkingsgroei en verstedelijking tot een huisvestingstekort; de woningwet van 1901 moest daar een eind aan maken. In de wederopbouwjaren na de tweede wereldoorlog kwam de woningbouw maar langzaam op gang. En in de jaren 80 van de vorige eeuw was ‘geen woning, geen kroning’ de leus van demonstranten die aandacht vroegen voor woningnood.@en

The Netherlands aims to achieve climate resilience and water robustness by 2050, necessitating an interdisciplinary approach to spatial planning due to the complex nature of climate adaptation. A critical need exists for subsurface data, especially for interventions related to underground elements like water storage, soil infiltration, and subsurface management. This need became particularly relevant when the Dutch government adopted 'water and soil guiding' as a core principle for spatial planning in 2022 (Ministerie van Infrastructuur en Waterstaat, 2022). Translating this principle into practical solutions is complex, requiring detailed knowledge of subsurface characteristics. The absence of such information can lead to issues like groundwater contamination and high-maintenance parks.

Despite the necessity for interdisciplinary and subsurface data, organizational, technological, and institutional barriers hinder the use of information models and standards in climate adaptation design. Currently, even though there are many subsurface models and standards available, the Netherlands lacks an integrated approach linking subsurface information models with local climate adaptation design. It also lacks an example of the use of standards to exchange planning information containing climate adaptation design interventions.

This research explores how subsurface data models can enhance urban climate adaptation design. By assessing existing models, it identifies data requirements for effective interventions based on Dutch policy documents. The paper introduces CLIMACAT, an online tool integrating subsurface information models and other crucial data in one online catalogue following FAIR (findable, accessible, interoperable, and reusable) data principles, tested in four Utrecht neighborhoods.

The findings emphasize the importance of integrating subsurface information models into urban planning to achieve more effective and context-sensitive climate adaptation interventions. Significant barriers include data accessibility and standardization. New spatial plans were standardized using Land Administration Domain Model (LADM) Part 5 (ISO 19152-5), tailoring some attributes for climate adaptation design, facilitating cross-border information exchange. This approach addresses specific challenges in the Netherlands and provides a framework for international adoption, contributing to global urban climate adaptation efforts. The research highlights the need for accessible subsurface data and interdisciplinary collaboration, supported by continuous technological and policy advancements.@en

The concept of circular economy (CE) is high on the agenda of many planning agencies in European countries. It has also become a prominent issue in European academic education institutions. It is expected that spatial planning and design can support and add the spatial quality dimension of such a transition towards CE. However, incorporating the concept of CE in an integrative manner in urban design and planning courses is challenging because of its metabolic and complex nature. This article presents the first results of integrating design-teaching activities at a faculty of architecture with an H2020-financed research project. The integration of research and design education provided the students with a situated and indeed transdisciplinary learning environment. Students understood that they needed to address challenges from a systemic perspective rather early in the design process, meaning to understand what the relations between different subsystems and their spatial structures are. Furthermore, the experiment provided evidence that the eco-innovative solutions developed by the students are seen as an effective option to achieve objectives for a transition towards CE by stakeholders.@en
