Successful Circular Bio-Based Construction Initiatives: Five Essentials from Case Studies

Abstract:

There are challenges surrounding circularity and the application of bio-based material in construction, but also potentials. This paper aims to identify success and fail factors for the initiation phase of construction projects and shows what is essential to realize affordable circular and bio-based. This was specifically investigated for initiators of construction projects, like real estate professionals, property owners and developers. Based on case studies, we describe what these actors should focus on and pursue before the actual construction starts. For the purpose of this paper, research was done and interviews were held with people involved in exemplary projects (case studies). The interviews focused on choices that were made during the initiation phase that were decisive for the degree of circularity and the extent to which bio-based materials were applied. Motivations and consequences were covered. We found that are five essentials for successful circular bio-based construction. These five essentials form the outline of this paper: 1. AFFORDABLE cost-effective & inclusive reuse; 2. FLEXIBLE prepare for future functions; 3. PASSIVE stay cool & healthy with bio-based materials; 4. INTEGRAL continuously reflect on circular bio-based benefits; 5. TRADITIONAL OWNERSHIP keep it, simple. In one case, all five essentials were put into practice, while in the other cases it was a combination of three or four essentials. The five essentials and cases in this paper can be used as inspiration for product and process and could help realize affordable and feasible circular bio-based constructions. By focusing on the essentials, initiators have guidance to prevent valuable resources (including energy) going to waste, today and in the future.
