1. 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

2. 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%. Prediction inaccuracies, especially during summer for cooling purposes.

3. Disregarding UHI effects Project motivation *J. Bouyer et al., Microclimatic coupling as a solution to improve building energy simulation in an urban context, Energy and Buildings 43 (2011) 1549-1559. Design for compliance – National BES tools InSMART kick-off

4. Traditional open-space architectural design Project motivation Urban physics assessment failures BEFORE AFTER Intense heat island after the bioclimatic retrofit InSMART kick-off

5. 31/2010/EC New public buildings New NZEB by 2018 and later for New public financed buildings.27/2012/EC Existing public buildings 3% of the total usable surface area Acceleration 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

6. Better than compliance Design freedom Improvement of BEP prediction accuracy => Reliable RES/EE investments in new and existing buildings (retrofit) HOW?? Recommendations: 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.
