Passive row house in the city

Test case for first passive and circular renovation in city centre

Flanders still has many single-family homes to renovate. However, individuals who wish to renovate according to circular principles quickly encounter a wide range of criteria that are not easy to understand with limited knowledge of the subject matter. Moreover, the translation from theory to practice is often lacking, and there are also many challenges on financial and legal levels.

With this project, Pixii (in collaboration with Vibe, Mosart, UHasselt, and Mechelen City) aims to find a solution to support and guide private builders in their circular construction plans. By guiding a concrete project of two private builders in Mechelen, we aim to identify all the bottlenecks (and opportunities) in both the customer journey, the construction practice, and the support process to develop a broader support process.

The support process is mapped out and translated into paper guides (roadmaps) and a website. The results of this project can be integrated by Pixii and Vibe into their training programs for renovation advisors who aim to guide individuals in their circular construction projects.

MOST IMPORTANT
RESULTS

  1. We supported two private builders in their passive terraced house renovation. We examined the construction details and various circular construction methods and conducted a detailed calculation to ensure that the plans comply with passive house standards.
  2. Thanks to the concrete case, we were able to identify all the bottlenecks of a private renovation process in an urban environment, concerning both the customer journey, construction practices, and support processes.
  3. The results and findings of the support process were integrated into our existing training programs, such as the circular construction training we organize in collaboration with Vibe.
  4. We compiled our process and findings into an informative website where architects, contractors, and clients can easily find tips and sample projects.

MOST IMPORTANT
LESSONS LEARNED

  1. A circular construction process unfolds differently than a normal construction process. It's important to involve every partner in the circular narrative beforehand and clearly allocate all roles and responsibilities.
  2. To avoid working at different paces, it's useful to establish a clear timeline that works for all parties. Everyone needs to put their schedule on the table and try to consider the entire scope of the project.
  3. It's easier to determine the circular goals first, and then make specific design choices. Conversely, it's much harder to make certain design choices circular later on. This conceptual thinking beforehand ideally involves multiple parties together.
  4. Aligning vision with needs is important; these two go hand in hand. When outlining a particular vision, consideration must already be given to the needs, knowing that those needs may change over the years.

WHAT DOES
THE FUTURE HOLD?

The two homeowners are continuing to finish their homes. We maintain the website, where new sample projects can always be added. The lessons learned have become a permanent part of our training programs. Our partners and ourselves have honed our knowledge of circular and passive renovation.
