2 ABRACADABRA is a three year long European Project i m p l e m e n t i n g a cost effective, strategy, involving eleven European Countries. COORDINATOR UNIVERSITY OF BOLOGNA PARTNERS ABRACADABRA aims and demonstrating to key the attractiveness of a new renovation strategy based on volumetric Add-Ons and Renewables (AdoRes) intended a set of assistant buildings unit(s) i.e. aside/on top/façade additions, or even entire new building construction that adopt the existing buildings (the assisted buildings) to achieve nearly WITH Zero ZERO Energy. URBAN SPRAWL The creation of these new Assistant Buildings Additions integrated with Renewable Energy Sources aims at reducing the initial investment allocated for the deep renovation of the existing building creating an up-grading synergy between The EU Framework old and new.

4 WHY? THE MOST CHALANGING WHY? IN WHY? ENERGY EFFICIENCY INVOLVES EXISTING BUILDINGS

5 WHY? WHY? CHALLENGE WHY? IN THE CHALLENGES.

6 (Pay back times of the investments range widely) a variation between 5-6 up to years can be observed as a function of the different hypothesised scenarios ---for nzebs up to 40 years---

7 The actual investment gap in the deep renovation sector is due to the fact that high investments are required up-front and they are generally characterized by a high degree of risk, by long payback times and by the general invisibility of the energy benefit..

8 And the problem asks for solutions The estimated costs of energy retrofit options indicate the need for additional tools and measures to be developed at social, legislative and market level, to counterbalance the large pay-back times of EE measures aimed at achieving nzebs in existing buildings.

9 Residential buildings in Europe 1 It has been estimated that over 90% of the buildings we see today will still be standing and occupied in (A. Joyce, Practical Approaches to the Building Renovation Challenge, Brussels, 9th December 2015)

10 Renovation rate in 2016? Yet currently the renovation rate in the construction sector is still 1,4%. It is a market that involves only in Italy over 11 million buildings

11 New construction rate in 2016? In 2016 the new construction rate accounted for more than 2% of the existing building stock in Europe

12 Roadmap for 2020 DENSIFICATION RATHER Could represent an alternative solution to the construction of new buildings, contrasting the consequent urban sprawl

20 WHY? IDEA AIM AMBITION TARGET Groups and stakeholders to involve Case Studies

21 Thus, ABRACADABRA aims at implementing a new, attractive renovation strategy based on a multi-benefit approach (substantial increase in the real estate value) provided by AdoRES Assistant buildings addition and Renewable Energy Sources to create an up-grading synergy between OLD and NEW

22 ABRA can thus result in a Market and legislative earthquake accelerating the revolution towards nearly Zero Energy in existing buildings

23 TO DO THIS ABRACADABRA needs to involve the main stakeholders and prove the potential of the innovative building renovation strategy promoted, based on AdoRES

25 Cashflow with incentives Cashflow without incentives

26 High costs in energy retrofitting have driven some experiences at EU level (i.e. SuRE-Fit, Reshape, Solar Decathlon, etc.) as well as pilot cases (Austria, The Netherlands) to focus on the strategy of rooftop extensions and additional volumes whose economic value in the housing real estate market counterbalances the energy retrofitting costs.

28 WHY? IDEA AIM AMBITION TARGET Groups and stakeholders to involve Case Studies

29 CONDOMINIUMS AND PRIVATE PROPERTIES (major legal obstacles exist in relation to add-ons. They are linked to property rights, tenancy and condominium law as well as local and urban planning rules)

30 TECHNICAL AND CONSTRUCTION COMPANIES there is a lack of confidence on technical feasibility of AdoREs (load bearing of buildings, which were not conceived for these additional volumes)

31 yet AdoREs may assume different configurations, depending on buildings type, structural conditions and urban capacity (aside or façade addition, or entire new buildings -the assisted buildings-)..

32 PUBLIC AND TERRITORIAL BODIES current regulatory environment often does not permit these kinds of interventions. Yet, in some countries public-private agreements and legislative rules have been introduced to incentivize the private market uptake of deep renovation

57 OPEN QUESTIONS FOR POLICY RECOMENDATION We are looking for best practices and counterbalancing measures that could be implemented in the current regulations at national and european level to foster Building Renovation thorugh AdoRes Social measures Neighbourhood services Social mix Services Parkings Enviornmental measures Soil permeability increase Urban nets empower Zero Energy renovation Integration of RES

58 OPEN QUESTIONS FOR POLICY RECOMENDATION How AdoRes could enter the building construction market and represent a wide spread prefabricated technology to be used in Energy Renovation of existing Buildings? Integration with energy savings Integration with RES Social factors customisation Seismic and static improvement

59 OPEN QUESTIONS FOR POLICY RECOMENDATION The strategy has shown a strong impact in the cost analisis evaluation of building renovation. Yet high up-front costs are required. Incentive schemes for AdoRES Assistant building building new to renovate the old Increase confidence in the stakeholders Lower the risks for investors
