1 Assistant Buildings addition to Retrofit, Adopt, Cure And Develop the Actual Buildings up to zero energy, Activating a market for deep renovation ABRACADABRA Buildings: 40% energy consumption 36% CO 2 emission in the EU Investments need to be scaled up in order to achieve the EU climate and energy 2030 goals

2 THE LARGEST CHALLENGE IS IN EXISTING BUILDINGS new buildings increase the building stock by around 1-1.7% every year

3 and... CHALLENGE IN THE CHALLENGES. WHY?

4 Pay back times of the investments up years can be observed as a function of the different hypothesised scenarios ---for nzebs up to 40 years CHALLENGING up-front investments, high degree of risk, long payback times and the general invisibility of the energy benefit.. 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.

5 5 High costs in energy retrofitting have driven some experiences at EU level (i.e. SuRE-Fit, Reshape, Solar Decathlon, etc.) 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.

6 Assistant Buildings addition to Retrofit, Adopt, Cure And Develop the Actual Buildings up to zero energy, Activating a market for deep renovation

7 AIM-AMBITION ABRACADABRA aims at implementing a new, attractive renovation strategy based on a multibenefit approach (substantial increase in the real estate value) (NON-ENERGY RELATED FACTORS for nzeb!) provided by AdoRES (new Assistant buildings addition and Renewable Energy Sources) to create an up-grading synergy between OLD AND NEW...

8 Densification A densification strategy could help providing an alternative solution to the construction of new buildings in natural areas, contrasting the consequent urban sprawl At legislative urban level ABRA = punctual densification policy fostering the investments in nzeb while preserving the natural areas around the cities...

9 TO DO THIS ABRACADABRA needs to involve the main stakeholders and convince them of the attractive potential of this renovation strategy based AdoRES in: Design (WP2), Share (WP3), Discuss, (WP3, WP4), and amend (WP3, WP4) technical, legislative and financial toolkits (involving STAKEHOLDERS and using CASE STUDIES) to achieve nzebs through AdoRES + Communicate and Disseminate (WP5)

11 Barriers: 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) 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) 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-)..

14 PUBLIC AND TERRITORIAL BODIES current regulatory environment often does not permit these kinds of interventions. Yet, in some countries public-private agreements have been introduced to incentivize the private market uptake of deep renovation To sum up: Need to struggle against the general lack of dialogue among the stakeholders. To react to the Technical, Legislative, Financial and Social gaps, ABRACADABRA will: enhance the architectural and estate asset value of the selected case studies and future promising ones, and will virtuously promote policy-led, market-led, social-led actions

19 Why do we believe in the nzeb feasibility through AdoRES? High transformations in EE retrofitting operations Against higher initial costs can balance the economic investment Up to set to zero the costs of standard energy retrofitting Other advantages - not quantified here- still remain

20 Which are more dependable on the social and psycological concernings of humans.. Attaining a more attractive environment
