REtrofitting PUBLic spaces in Intelligent MEDiterranean Cities
The REPUBLIC-MED project The role of building and urban physics analyses in energy and environmental
policy making
Presentation in the InSMART kick-off
Project motivation
Design for compliance – National BES tools
Disregarding energy behaviour
The ground floor and the first floor is stone (rubble) wall, while the second floor is a brick wall. The ground floor and the first floor include some coated surfaces surrounding the openings. The openings frames are synthetic double glazing with spacing 12mm, while the ratio of frame/glazing is 20%/80%.

InSMART kick-off
31/2010/EC
New public buildingsNZEB by 2018 and later for New public financed buildings.
27/2012/EC
Existing public buildingsAcceleration of public-buildings renovation: By 2014 onwards 3% of the total usable surface area of buildings owned or occupied by the central government should be renovated each year towards the accomplishment of minimum energy performance requirements set in each MS.
Recent directives
InSMART kick-off
Better than compliance
Design freedom
Improvement of BEP prediction accuracy => Reliable RES/EE investments in new and existing buildings (retrofit)HOW??
Recommendations*:- Account for occupants’ behaviour (questionnaires, smart meters, stochastic
modelling)- Dynamic simulations (max: Hourly time steps)- Extension of boundaries to account for energy grid and microclimate impact- Optimization- Etc.
Directives implementation – Study phase
Design for reliable
predictions
Design for compliance
*Evaluating and Modelling Near-Zero Energy Buildings; Are we ready for 2018?, JRC Technical Reports, Expert meeting 30-31 Jan 2012, Glaskow.

Design for compliance
Methods that respond to new requirements for directives
implementation
Buildings- Indoor-outdoor interactions- Energy behaviour- Retrofit technologies
Open spaces- UHI assessment- New insights on urban
environmental planningOptimizationPilot applications
Enrich design for compliance- Accounting for external microclimate
effects- Accounting for behaviour- Optimization=> Possibilities in cost-
optimal minimum requirements- Train the stakeholders
Plans to introduce approach to policy makers
Training seminars
InSMART kick-off
- Acknowledgement of today’s study methods drawbacks
- Suggestion of holistic methods to enrich design methods for buildings and open spaces retrofit
- Innovation transferring from scientific literature to enrich Design for Compliance
- Guidance to policy makers by providing guidelines to plan retrofit projects & relevant investments
- Influence relevant stakeholders (engineers and architects)

InSMART kick-off
- Innovative methods existing in scientific literature responding to the requirements of the previous flow charts.
- Suggestion of coupling approaches towards the development of integrated and holistic methodologies for buildings and open spaces retrofit.
- Experimentation in 5 pilot sites in Greece, France, Italy, Spain and Croatia.
- End users participation at project implementation level (e.g. questionnaires), Skills’ elevation through training seminars and awareness raising through national and transnational events.
- Identification of DC/DRP bridging potential
