Development of optimal (cost) renovation strategies for architecturally and historically valuable blocks in the context of the IST (Agency for Innovation by Science and Technology) experimental 'Housing renovation: innovation in energy-efficient remodelling'.

Based on a specific case study, it is the consortium's ambition to gain insight in determining cost-optimal renovation scenarios and to translate these into tools and guidelines that can be deployed broadly in the renovation of (protected) blocks, both from technical aspects of, the price calculation and the energy-efficiency achieved.
A method is developed by which each step of the process is optimized; from the audit of the building envelope, to a flow chart for hygrothermal risks, and determining a cost-efficient optimum between constructional and technical installation- interventions.

Case: the complete restoration and rebuilding of block 'Kiel Park Tower'
The 3 towers by architect Jos Smolderen, each with 96 housing units, were built in several phases between 1959 and 1961 for the social housing association 'De Goede Woning'. To keep the buildings habitable according to current standards, extensive renovations are necessary. The tower buildings´ physics and comfort no longer comply with current needs.

Specifically, this project was chosen to address a number of recurring questions regarding renovation in detail, and is based on 7 specific, predetermined issues:

  1. Specificity of the architectural renovation of an historically valuable building.
  2. Which energy ambition is feasible, what is cost-efficient? Insulation or installation?
  3. Diversification of the various installations to be placed.
  4. How to achieve air tightness in renovation? Which performance is feasible? What is the cost?
  5. Impact of user behaviour (in general energy consumption and interaction techniques).
  6. Hygrothermal analysis of the building envelope.
  7. Monitoring of different installations, with feedback to the users.
