Ensuring Sustainability in Brownfield Revitalisation as PDF

Information that can be assigned to three groups was requested for all six
areas of appraisal:
■ Technical building data
■ User behaviour and user involvement
■ Surrounding conditions and/or infrastructure (which cannot be
influenced by the building).
A significant amount of the requested information cannot be verified by
applicable regulations and standards (e.g. energy saving certificate
pursuant to German legislation EnEV), but is at the discretion of the
handling clerk (e.g. Point 1.3.1, ‘Ensure good operating instructions’).
Furthermore, detailed measures for saving energy and reducing
consumption are requested (e.g. Point 4.1.2, ‘Installation of water-saving
shower heads’), but any installations may change significantly during use.
The trial run is made using four alternatives for the constructed sample
object, particularly in order to be able to examine the effects of the
installations which can be changed or modified by the user of the building:
Sustainable Building Design
1. Entering the actual building data
2. Optimising the data in the area of energy (user behaviour) while
retaining the technical characteristics, and in the quality of living
conditions (surrounding conditions)
3. Optimising the technical characteristics in the areas of energy
and material
4. Optimising all areas
While Alternative 1 (entering the actual data) attained an appraisal of 2.5
stars and was certified with a CO2 reduction of 66 % per flat and year
(although the question could be posed: 66 % of what?), Alternative 4
(optimising the data entries in all six areas) was able to attain an appraisal
of 3.5 stars with the same CO2 reduction. The reason for the different
appraisal can mainly be found in the areas of water, health and quality of
living conditions. These are, however, particularly determined by data given
for detailed technical measures and assessments of behaviour.
