References
Hard to justify ambitious building retrofits by energy savings only Return on investment to divide energy consumption of a building by two is more than 25 years DECADIESE methodology to capture the sustainable value of a building with an original focus
beyond the scope of classical analytic methods by extending the perimeter of associated stakeholders in order to allow ambitious building projects.
Context
Make the methodology more reliable by Going further in scientific validation Testing the methodology in more extrem case studies
Develop professional DECADIESE software to support the methodology For different types of applications (offices, housing, hospitals, schools…) For different businesses (building owner, engineering contractor…)
Implement DECADIESE methodology on on-going buildings projects
Perspectives
ANR (French research agency) project
Externalities domain (not detailed here)
Functional performance domain Usage function costs domain
Prototype tools developed to support DECADIESE methodology
DECADIESE methodology partially applied onSkyline building in Nantes (France)
Building designed, constructed, operated andpartially occupied by Bouygues subsidiaries all data available Good results obtained by applying functioncosts and externalities parts DECADIESE is feasible
Serious game developed and run for one day to test appropriation of the methodology by real building sector’s actors
High interest from these actors New directions for future developments
Application & first results
DECADIESE objectives
Aiding decision for buildings’ project owners
thanks to:
• A functional perspective centered on users
• Externalities elicitation to identify new value creations
Approach based on Value Management andFunctional Analysis [NF EN 12973:2000, Ehrlenspiel et al. 2006]
Building Space
Comfort
Protection
Goods & tools
Relationship
Site
Semiotics
Usage functions[Gobin 2006]
Systems & components
Repartition keys
Costs breakdown by
usage functions
Approach based on a list of 95 functional performance criteria and fuzzy logic to aggregate
functional performance on usage functions
Preferences transcripted by the
building’s project owner
User preferences
Willingness to pay
Functional performance
criteria
Aggregated functional performance
Usage functions
Aggregated functional
performance on qualitative scales Identification of fuzzy
logic expert rulesArbitration

project
Elementary functional performance
Perceived value
Selection of adapted criteria
Evaluation of selected criteria
Examples of criteria : winter/summer temperature, surface/occupant, distance between parking and entrance, feeling of well-being, appraisal of colors…
