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%.

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

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
