Replication considerations for the full scale deployment throughout Europe of the REnnovates concept. In Europe, differences in climate conditions, building typology, energy regulations, home ownership, citizen association or financial mechanisms, lead to varied housing scenarios where single rigid solutions are difficult to implement. The objective is to present the audience the challenges faced for the industrialization and full-scale deployment of the REnnovates concept and some possible approaches to overcome these differences.

Editor's Notes
- Thank the audience, the partners for giving me the opportunity to present part of the work. Thank the Commission. Short TOC Introduction Process Results Conclusions
- Present what the presentation will be about
- Primary production of energy by resource - 1 000 tonnes of oil equivalent Short Description: Any kind of extraction of energy products from natural sources to a usable form is called primary production. Primary production takes place when the natural sources are exploited, for example in coal mines, crude oil fields, hydro power plants or fabrication of biofuels. Transformation of energy from one form to another, like electricity or heat generation in thermal power plants or coke production in coke ovens is not primary production. Electricity consumption by industry, transport activities and households/services (GWH) - GWh Short Description: This consumption stands for final energy consumption. This means that the consumption in industry covers all industrial sectors with the exception of the energy sector, like power stations, oil refineries, coke ovens and all other installations transforming energy products into another form. Final energy consumption in transport covers mainly the consumption by railways and electrified urban transport systems. Final energy consumption in households/services covers quantities consumed by private households, small-scale industry, crafts, commerce, administrative bodies, services with the exception of transportation, agriculture and fishing.
- Final energy consumption in households by fuel - % Short Description: This indicator presents the share of six types of fuel to the final residential energy consumption: solid fuels, total petroleum fuels, gas, electrical energy, derived heat and renewable energies. The share of each fuel is expressed in per cent of the total consumption. The indicator has been chosen as a proxy for indicators in the key area 'Improving buildings' of the resource efficiency initiative. This area focuses on the energy spent in households for heating purposes and how the amelioration of buildings can contribute to energy-saving plans. Eurostat collects data on total energy consumption in households split by fuel category. More detailed data for energy consumption in households (e.g. energy for space heating, space cooling, water heating and cooking) will be collected in the future under the Commission Regulation (EU) No 431/2014 of 24 April 2014 amending Regulation (EC) No 1099/2008 of the European Parliament and of the Council on energy statistics, as regards the implementation of annual statistics on energy consumption in households. See also indicator 'Final energy consumption in households (t2020_rk200)'.
- Share of renewable energy in gross final energy consumption - % Short Description: This indicator is based on the definitions included in the Directive 2009/28/EC(Renewable Energy Directive) on the promotion of the use of energy from renewable sources. It is calculated on the basis of data collected in the framework of Regulation (EC) No 1099/2008 on energy statistics and complemented by specific supplementary data transmitted by national administrations to Eurostat. This indicator measures how extensive is the use of renewable energy and, by implication, the degree to which renewable fuels have substituted fossil and/or nuclear fuels and therefore contributed to the decarbonisation of the EU economy. It also show what is the progress on EU level towards Europe 2020 target for renewable energies of increasing the share of renewable energy in gross final energy consumption to 20% by 2020. More information about the renewable energy shares calculation methodology can be found on the Eurostat website. More information on renewable energies can be found on the DG Energy website.
- Present the business model as today with the different Stakeholders Talk about blockage
- Indicate the key factors
- Possible solution Rennovates
- Benefits The Rennovates concept has been thought for an specific context But how does this concept adapt to other countries?
- Indicate that the approach to conduct the presentation was not clear. We have several demonstrators with different implementations and results. Not sure if it is wise to present all of them one by one or follow a different approach. We have thought that the best is to focus on the process
- In each country we developed business Models. We analysed the market. So we confronted different Stakeholders (neighbourghs, electricians, energy cooperative, DSOs…) and like good engineers they analyse the situation with many BUTs (cost, reliability of the systems, maintenance, ROI, Space, …) Stakeholders (owners) wanted guarantees. Building conditions were also analysed Competitors More importantly norms and regulations both for building renovation and in the energy field. Main conclusions for each country (NL, Poland and Spain)
- For each country we built the SWOT canvas for the Rennovates concept in those cases. Explain breifly the Spanish case
- We also drew the stakeholder maps Explain briefly the stakeholder map for the Polish case.
- We also run simulations for the expected energy production, consumption, savings through optimization, comfort, etc Different standard tools were used for this Modelica, Energy Plus, Design Builder, TRNSYS, … The objective is to contrast the simulation results with the demonstrator results. Another objective is to use those simulation models as designing tools for new implementations. Consequently they need to be contrasted with the real scenarios
- With the simulations and the business case analysis we withdrew business KPIs (ROI)
- We also identify and estimated KPIs on energy (savings demand), production with renewables and confort.
- The next step is to test the technologies and implementations in real demonstrators. Explain Dutch case (large demonstrators): Several sites (Soesteberg and Heerhugowaard) Prefabricated façades and EM Bulding level optimization (with and without batteries) District level optimization (district batteries)
- In some demonstrators the results of the business model analysis condition the implementation. For example the building typology condition the implementation in the Spanish case. For its implementation the Spanish demonstrator considered the following requirements: Implement interventions compliant to the REnnovates concept. Assess a block of houses constructed previous to the establishment of the technical code (CT 79) in 1979. The building should be 3-stores height at most. Target houses where the impact of renewables is higher. Houses with electrical heating systems or without any heating. Design and build a Centralized energy module. This centralized energy module will to be shared among several dwellings. This is a new concept in REnnovates and becomes key in the Spanish pilot. Evaluate External Thermal Insulation Composite System (ETICS) as a general solution for façade retrofitting. The demonstrator looks for local optimization at building level (similar to the Dutch case). That is, optimization of self-consumption for domestic hot water and spatial heating
- Similarly the Polish case is conditioned by the sources of energy available at household level (DH difficult to substitute) and the building topology. Thus a different approach is proposed combining renewables and CHP
- The architecture proposed and the scope (large set of buildings) sometimes increase complexity to the implementation of the demonstrators.
- We started by selecting the best location according to requirements identified during the business case. Buiding target. Ownership Type of energy used
- Started talking to stakeholders So I confronted different Stakeholders (my neighbourghs, electricians, energy cooperative…) and like good engineers they analyse the situation with many BUTs (cost, reliability of the systems, maintenance, ROI, Space, …) They wanted guarantees.
- When I first heard about Rennovates I said I want this solution for my house. My neighbourghs place many BUTs and still I am preparing numbers to convince them. If a local “controlled” place we found many engineers you can imaging when we approach owners
- After the building selection process, negotiations with owners, agreements and permits, rehabilitation of the building started. For the implementation process in Spain we must highlight two key interventions: Façade retrofitting using ETICS Centralized Energy Module To start with FAÇADE RETROFITTING For façade retrofitting, we use External Thermal Insulation Composite System, short ETICS. ETICS offers high resistance to impacts, algae, fungi and cracking. It also offers high thermal insulation and resistance to atmospheric loads, and has high permeability. On the contrary, ETICS Industrialized systems are still not enough developed to be competitive in Spain. However, it is interesting to keep an eye on its development in the near future.
- The second significant component for the Spanish implementation is the Energy Module We have designed and built a centralized energy module more appropriate for the Spanish housing typology which are buildings with several apartments/studio’s The module has similar components to those used in the Netherlands, but we equipped the Spanish ones with higher capacity vessels, more pipping connections and a more powerful heat pump. The module is plug and play making it easy to install from an engineering perspective. Its potential to be used for ‘cooling’ under hot climate conditions climate control in tropical conditions is yet to be tested Its potential to be used for ‘cooling’ in warm weather conditions is to be tested.
- Roof installation of PV is another intervention. The renewable contribution comes from this element. While in some cases the roof Surface is associated to an EM for an individual house, in other cases the whole roof Surface is used for an EM servicing several dwellings. Mainly we have used energy contribution from renewables for heating and DHW. Energy from the PV panels can be also used for electricity inside the house. This improves selfconsumption inside the dwellings which has been one of the objectives. Sharing a PV installation and being able to use the energy inside the dwellings can be an improvement in selfconsumption (not posible with actual regulation).
- The objective for the district battery implementation is to be able the impact of that solution to: Reduce grid investment for the DSO Reduce outage (imbalance regulation) Contribute to the national grid reserve
- In parallel to the site or demonstrator interventions a platform was built to accommodate data and tools necessary for optimization, data aggregation and interoperability (USEF). Data from all the demonstrators is acquired and store there. Data analysis can be performed at platform level. The platform is essential for evaluation of the interventions and optimization approaches implemented. The platform also enables the collaboration with other partners. For example for the negotiation of the electricity flexibility with the DSO using USEF (interoperability protocol)
- Data collected from the demonstrators can be analysed at platform level. HMI and plots are available for that purpose. Data collection and storage follows several steps: Sensors measure different parameters at EM and dwelling level. Data is collected at the Gateway using interoparable and standard protocols (EEBus). Data is transferred to the platform where it is stored for analysis, optimization calculations or visualization.
- The platform presents a multilanguage Portal with dashboards, API for consumption, … for the different needs of the stakeholders (residents, aggregators, …)
- Evaluation has also been performed by means of simulation. Simulation results have been compared to real data collected at platform level. The figure shows the software used and the evaluation schemes used in Poland
- In the first part the most relevant results are: Business case analysis in several countries SWOT Stakeholder maps Modelling tools for designing and dimensioning solutions Simulations
- Complete solution for NL. Valid for similar markets and conditions Belgium, UK,… Elements for adaptation of the concept in other countries (façade with ETICS, Centralized EM, CHP, …) Demonstrators for Spain and Poland Technological platform (data management, tools …) Providing devices for data acquisition, analysis, tools (PV forecast, energy savings …) Interoperability and standardization (EEBus, USEF) Collaboration (win – win) between different agents Smart control-Optimization (flexibility – Energy management)
- Find room for collaboration among stakeholders (win – win) Able to deploy several demonstrators to validate the Rennovates concept Technological platform prepare for the energy market (aggregation, interoperability, analysis, optimization …) Interoperability and standardization (EEBus, USEF) Smart control-Optimization (flexibility – Energy management)
- The main challenges to overcome in Spain are: Regulation restrictions: The Spanish energy regulation is very restrictive and does not encourage the introduction of renewables. Toll fees make the investment on renewables not interesting for the possible prosumer. Changes of the current regulations are necessary to stimulate the production of clean energy. Currently the policy makers are sending contradictory messages and actions on how to move forward in the energy transition Energy flow between prosumers and DSO should be stimulated by regulations. After positive regulation changes, additional values like energy flexibility (enhanced by district batteries of shared installations) will become more relevant. Return on Investment: The current estimated return of the investment is too long to seduce house owners. We need to find ways to shorten the ROI period. Sharing capacity could reduce the capacity fee considerably. Owners should see Rennovates as an opportunity to increase the property value. Funding opportunities need to be explored looking for win-win situations between stakeholders (owner, construction company, aggregator and DSO). Social acceptance: For a building with several dwellings, the implementation of the REnnovates concept has to be accepted for at least 2/3 of the owners. We need facilitators who are trained move people to embrace the concept. These facilitators could also seek funding opportunities for each project. Administrative Processes: During the implementation of the project, we were faced with difficult administrative processes Usually engineering companies deal with matters related to the construction or retrofitting of a building. In Rennovates they must record administration processes related to energy management with the DSO the drafting of contracts and quota’sand they have to provide additional connections,). This requires expertise with permits and subcontracting Technical challenges: Refers to works being performed while tenants in the houses, size of EM, battery inclusion in the house, … Stakeholders need to be informed all the time about the technical implementations and their consequences.
- Continue evaluating demonstrators District batteries Central Energy Module optimisation. Address cooling Stronger Involvement of Financial entities Stronger Involvement of DSO, BRP and Energy aggregators Follow closely regulation evolution and disseminate results towards public administration and regulators Use renewables and the Technological Platform in other contexts (public administration, industry …)
- Example of a demonstrator for public administrator that integrates data in the same platform as the data obtained for the residential demonstrators.
