2. Index A few words about CITyFiED project
Why a novel sustainability procedure?
Existing ones
Sustainability procedure at-a-glance
Application into Spanish demonstrator
Energy evaluation (and economic)
ICT methodologies
Quality control of interventions
Citizen engagement
Life Cycle Analysis (LCA)
Conclusions

3. A few words about CITyFiED
Full title: “RepliCable and InnovaTive Future Efficient Districts and cities”
Grant Agreement #
Aim
Development of a replicable, system and integrated strategy to adapt urban ecosystems into the smart city of the future, focusing on reducing the energy demand and GHG emissions and increasing the use of renewable energy sources by developing and implementing innovative technologies and methodologies for building renovation, smart grid and district heating networks and their interfaces with ICTs and Mobility

4. A few words about CITyFiED

6. Why novel sustainable procedure?
Sustainability concept involves new models of socio-cultural relationships
Challenge in terms of urban environments
New trend in certification of buildings
Current protocols and standards
Difficult to implement
Require experts for the certification
Benchmarking is time-consuming
Increase the cost in their implementation
Missing important pillars: end-users, ICTs and LCA
Two main standards
BREEAM
LEED

7. Why novel sustainable procedure?
Benefits of the new approach
Based on simple KPIs for the evaluation instead of credits
Objective vs subjective
Real measurement data
Avoiding simulation
Inclusion of LCA and ICT tools evaluation
Widen the scope into Smart Cities, not only buildings
Considers the end-user in the loop

8. Sustainability procedure

9. Application in Spanish demo
Located in Laguna de Duero-Valladolid (Spain)
31 buildings
Conditioned area 143,000 m2
Concrete as main element
Gas-fired district heating
Renovation
ETICS with U-value of 0.34 W/m2K
Biomass district heating
HEMS, BEMS, DEMS

10. Application: Energy IPMVP-based assessment New cross-effect concept
Option C
KPIs:
Primary/Final energy demand/consumption
Effects in the economic savings
New cross-effect concept
How energy savings affect in:
Cost savings
LCA
Digital homes
Social acceptance
Quality control

11. Application: ICT solutions
How ICTs help the energy savings
Implementation of HEMS, BEMS and DEMS
Decision making tools
How ICT tools help in energy-user awareness
Changes in the behaviour?

12. Application: Quality control
Proper development and implementation of renovation
Quality in the materials
Conducts to more energy efficiency
Ensure a sustainable process
Low waste/dust/noise implementation of the process
Environmental protection
Materials quality
Final measurements for quality
Blower door tests, thermography…
Documentation and training
BIM-supported

13. Application: Citizens
End-users need to be involved in the loops
Survey-based evaluation
Including log book
Different dimensions
Social
Related to the citizen satisfaction and participation degree
Environmental
How the behaviour of end-user has been influenced
Improvements from subjective perspective vs objective values
Economic aspects
How the bill reduction affects end-users
Technical
Final quality of the renovation project

14. Application: LCA ISO 14040 -based Inventory analysis and assessment
Included within the global methodology and not as an isolated evaluation process
Inventory analysis and assessment
Characterize the environmental baseline
System boundaries definition
Model based on attributes of the systems and materials
Interpretation of results
Impact of the technologies
In terms of environmental footprint

15. Conclusions
Current standards for evaluation are complex and time- consuming
Also, missed some important pillars
Citizen engagement
LCA
ICT solutions
Based on subjective parameters and simulation
New approach reduces complexity
Includes all the elements in the loop
It is based on KPIs (objective measurements)
Sustainability as a concept for Smart Cities
