The NonHazCity guide for design & construction of tox-free, circular & climate friendly municipal buildings
15 September 2025
This guide presents practical insights from pilot projects conducted under the NonHazCity3 initiative and includes the technical implementation process for construction or renovation work. It emphasizes a systematic approach to the entire building process—from early concept development to final verification. Following this approach helps municipalities align with tox-free, circular, and climate-friendly goals, even when national legislation only sets minimum standards.
The guide features detailed descriptions of pilot activities, individual case profiles, and the construction phases tested, along with the associated results and economic considerations. It showcases best practices, drawing on real-world case studies to illustrate both successful outcomes and lessons learned.
The intended audience is other municipalities interested in applying a tox-free, circular, and climate-friendly approach to ensure long-term relevance. The guide contains adaptable elements suited to local conditions and offers practical advice and methods for implementation.
Municipalities can learn from the experiences of NHC3 pilot partner municipalities—how they operated, the practical knowledge they gained, and what can be achieved with dedicated teams and resources. This information will be highly educational and inspiring. The outcomes of these pilots can challenge traditional construction practices, fostering a more sustainability-focused mindset and encouraging the adoption of innovative ideas.
