RGD Building Portfolio Scan

Project > Opportunities for sustainable redevelopment

The RGD manages and maintains all the real estate for the Dutch government. In such a large portfolio, a large number of buildings are suboptimally used. We developed a scan to analyze a specific object, identify potential beneficial uses and plot out a redevelopment plan.

Context

One of the great challenges to achieve long term sustainability consists of converting our existing building stock to a sustainable state. This is often 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. 30 buildings were investigated for the first part of the study. The result was a functional tool for effective, communication and management of conversion projects. 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
The approach creates four categories of evaluation. These are nested in functionality. This allows a clear phasing and selection:

A- User & Management
B- (partial) Systems & Devices
C- Structure & Spatial Configuration
D- Integrated Solution

It subsequently measures the resulting performance in the following categories:

*Energy (EPBD) performance *Flexibility *CO2 emissions *Financing & Management *Health & Quality

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:

*A typical 60’s urban office block (5 stories), empty at time of study. *A large prison complex, built in various era’s. *A large monumental government building *A ’70s office block in the Hague *A ’70 standard typology block, renovated in the ’90s

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 restructuring and reprogramming concepts applied, including partial privatization, urban integration, reconfiguration, zero carbon and autarktic conversion options.

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