Sustainable Conversion of Existing Buildings

One of the great challenges to achieve long term sustainability goals consists of converting our existing building stock to a sustainable state. This is complicated by existing managerial, economic and physical structures that do not let themselves be converted easily.

The Government Building Agency (Rijksgebouwendienst) of the Netherlands commissioned Oneplanetarchitecture institute (OPAi) in cooperation with Except to perform a study about this issue, with 30 buildings, mostly in city of the Hague. The study was subsequently trialed on five example buildings.


 

 

Methodology:
The team developed a methodology that performs the following functions:

  • Streamlines communication between client, designer, consultants and builder
  • Presents a clear approach method to evaluate the different possibilities and stadia of conversion
  • Allows for integrated, innovative and progressive solutions that interact with urban, social, financial and physical parameters
  • Creates an easy to understand communication tool for all parties involved
   
 
 
 

Conversion Projects:

After a quick-scan of 30 buildings, five buildings were selected, for which comprehensive re-development schemes were developed. The buildings were selected for their diverse typologies. They consist of:

  • Korte Voorhout: A typical 60's urban office block (5 stories), empty at time of study.
  • A large prison complex in Scheveningen, built in various era's.
  • The palace of Justice in Amsterdam, a partial monument.
  • Bezuidenhoutseweg: A '70s office block in the Hague, home to the ministery of Economic Affairs.
  • The central office of the National Ombudsman in the Hague.
   
 
 
 

Results:

The communication tool developed allowed clear communication about various stages and approaches of intervention. Some buildings were only energetically optimized, while others had complete restrucuring concepts applied, including partial privatization, reconfiguration, zero carbon and autarktic conversion options.

We continue to refine the methdology developed, and to apply various approaches to converting our existing building stock.

A slide presentation of the approach can be downloaded below in PDF format (5mb).
