  6. 6. www.grow-smarter.eu Final Conference I GrowSmarter I 03.12.2019 Need to include other indicators besides energy and emission savings on the evaluation of energy refurbishment Technical and Economic Indicators I-Scope II-KPI‘s III-Lessons learnt IV-Replication CANYELLES TER 31 LOPE DE VEGA MELON DISTRICT  12% in Final Energy  40 % in Primary Energy  61% heating 39% cooling  33% in Electricity  61 % in Gas  20% in Primary Energy  10-60% Air Leakage  Increase in confort (questionnaires)  13% property value  41% heating  20% in Final Energy  41% in Primary Energy  30-63% Air Leakage  Increase in confort (questionnaires)  35% heating  17% in Final Energy  35% in Primary Energy  39-48% Air Leakage  Increase in confort (questionnaires)
  7. 7. www.grow-smarter.eu Final Conference I GrowSmarter I 03.12.2019 A number of barriers have been identified that need to be solved for the residential refurbishment to be fully deployed in mild climates Learnings and conclusions I-Scope II-KPI‘s III-Lessons learnt IV-Replication  Type of property: large part of dwellings are in multifamily houses and ownership is really fragmented. There are in average 15-25 family units per building.  Income levels: 45% of all dwellings is lower than 1,500€. Different incomes on all dwellings and different willingness to pay within a building.  No planning for long-term on multifamily buildings: need to include energy aspects on the technical building inspections. National Context Technical barriers  Complex norms and ordinances: interventions on the façades are considered as an increase of volume, hence higher license procedure. Local ordinances do not account for rooftops as energy generators spaces.  Lack of accuracy on the works implementation. Need to include performance contracts into the contractors bid. Economic barriers  Large paybacks in mild climates: paybacks can reach 30 years or in case no heatin demand on the baseline, there will be directly no payback.Need to value other factors than energy savings  Difficulty to access financing: ownership communities struggle to apply jointly for finance. High interests for a consumer loan and not able to apply for a mortgage loan.  Subsidies need to be restructured and be designed to dynamize the market

  9. 9. www.grow-smarter.eu Final Conference I GrowSmarter I 03.12.2019 Large market to exploit but need to establish sound and secure business models for the private sector to invest Roll out of residential refurbishment services I-Scope II-KPI‘s III-Lessons learnt IV-Replication  The National Enery & Climate Plan (2021-2030) establishes 1.2M of residential building to be refurbished in the coming 10 years with a budget of 44M€ (80% coming for the private sector)  On the Photovoltaic self consumption: an objective of 300-700MW per year to 2030 at Spanish level and 200MW per year to 2030 at Catalan level. Potential market Naturgy actions  Public and Private stakeholder discussions (contractors, manufacturers, administration, engineering and architecture, financing, etc.) to build a sound business model for different housing typologies.  Definition of different level interventions to build an off-the shelve product for residential refurbishment
