4 CHAPTER I Introduction Request2Action is a programme across nine European countries, co-funded by the European Commission. Its focus is on how data from Energy Performance Certificates (EPCs), alongside other data, can be used to promote home energy efficiency. The current state of the building stock is being monitored in many European countries and energy related information is collected more and more in regional or national EPC databases. In order to get insight into the development of the energy efficiency in buildings and the acceptance of the recommendations of EPCs, the analysis of the recorded data is necessary. Investigations in the use of EPCs in refurbishment market show that in many countries there is little experience in monitoring the implementation of EPC recommendations. One of the tasks in work package two was to organise a best practice meeting and to invite representatives of the countries with EPC databases to share their experiences on monitoring activities with different stakeholders from the governmental, educational and private organisations. The more comprehensive elaboration on the EPC databases is integrated in the deliverable 2.1 Report on existing monitoring initiatives and databases. 4

5 CHAPTER II Stakeholder/Best Practice Meeting Since the certificates were first introduced in 2007, a number of European countries have stored data from EPCs in monitoring databases. Other countries are just starting to introduce such databases. Less attention has been paid to the potential of mass data gathered together from millions of EPCs. The EPC data could be used for many purposes. In order to show how the information is being used in different countries, an expert workshop was organized in Belgium on November 4 th 2014 (14:00-17:00) in the Auditorium of Vleva (Liaison Agency Flanders-Europe), Kortenberglaan 71 in Brussels. Experts from the following sectors were invited to this Best Practice event: EPC database administrators Companies particularly energy suppliers who have the potential to use EPC data at scale Academics working on energy policy and looking into big data use approaches. Policy makers at national and European level. 48 participants from 11 countries, 14 energy agencies, 8 universities, 5 private enterprises and 3 governmental organizations including CA EPBD attended the Best Practice Meeting. The Meeting was organised by the Request2Action project team, to: Discuss the first results of the internal survey on EPC database systems in the partner countries; Give an overview about the features of existing EPC database systems across Europe and discuss the outcomes of the BPIE study (Title: Energy Performance Certificates (EPC) across the EU: a mapping of national approaches ); Show best practice examples from Italy, Portugal, UK, Ireland and the Netherlands. This meeting offered the opportunity to validate existing information validated and to obtain new information (for example: information about the EPC database systems in Scotland and Ireland). Looking at examples from across Europe presented at this meeting, the participants could see how EPC monitoring databases can be used to: Track the progress of energy improvements key data for governments in complying with the Energy Efficiency Directive; Identify the buildings that most need energy upgrades data that can be used not just by governments but also by legitimate other stakeholders; Enable building owners and occupiers themselves and housing market actors to see the energy performance of entire communities; Monitor the quality of energy performance certificates and assessments. 5

6 CHAPTER III Best practice examples The participants were welcomed by Rui Fragoso from the Portuguese Energy Agency, ADENE. After a short introductory, explaining the context and aims of the meeting, energy experts presented the outcomes of surveys and how the EPC data is being used in exemplary countries. The main points of the presentations are described in the following section. The presentations themselves are provided in the appendix. 1. Energy Performance Certificates across the EU A Mapping of National Approaches: a survey by BPIE By Aleksandra Arcipowska (BPIE) Based on the latest BPIE study, Aleksandra Arcipowska (BPIE) gave an overview of the state of EPC activity and EPC databases across Europe. The BPIE study provides at evaluation of the EPC schemes implementation in Europe by focusing on the quality, availability and usability of EPC data. It builds on BPIE s survey from 2014 on EPCs conducted in cooperation with national experts from 23 Member States and Norway. The study indicates how many EPC databases central or regional exist or are planned across Europe. It also shows the format of the collected data in different countries, how the information is uploaded into the database, and who has access to the data. Some examples (Denmark, the Netherlands, Hungary and Ireland) were shortly introduced to give a better picture of the databases. The presentation concluded that a well-functioning EPC system accompanied by an EPC database can provide a ready-to-use source of information on the building stock. This makes the quality of EPC information crucial. The increasing number of best practices across Europe demonstrates the added value of EPC data for policy making and monitoring as well as for research and analysing. The further support of the Member States in developing and strengthening the central EPC registers, especially in relation to the privacy issues, is needed. The standardised methodologies and formats of data collecting and sharing should be promoted. The EPC schemes as a tool could be used for mapping and monitoring the national and European building stock and, if properly implemented, it could allow for the assessment of real market needs and the potential for energy efficiency improvements in the building sector. 6

7 2. Status of EPC Databases in Partner Countries A Survey of EPC Databases in the Partner Countries By Naghmeh Altmann-Mavaddat, AEA In this workshop the early findings of the survey which is done in the work package 2 on the EPC databases in the 8 partner countries was presented by the work package leader. There are 7 existing EPC databases and one newly established among the Request2Action partner countries (see Figure 1). Figure 1: The scope of EPC collection in the partner countries The data is mainly being used for statistics, research, strategies and infrastructural planning, subsidies and trend identifications in the building and real estate sector (see Figure 2). 7

8 Figure 2: The use of EPC data in the partner countries In particular, the information was used to verify the effectiveness of some NEEAP (national energy efficiency action plans) measures and to evaluate the impact of energy saving measures. In some countries like Portugal the data was used in redesigning the building codes and defining the baseline of buildings energy performance. The EPC databases have supported the designing and redesigning of funding schemes in many countries. 3. Best practice example: Italy Using Energy Performance Certificate databases: experience of Lombardy By Mauro Alberti FINLOMBARDA Lombardy is one of the first regions which established an EPC database after introducing EPC in Italy. The EPC database in Lombardy was established in Almost all the residential buildings in this region have an EPC all of which are collected in the EPC database. The EPC register is accessible from regional and municipal authorities and is rarely used for statistics and research. This region has its EPC database open to agencies for studies, to notary officials or on demand (also for trades). The CENED register (the EPC register in Lombardy) is referred to building cadastre and is integrated, together with the regional Cadastre of Building Heating/Cooling systems (CURIT) and the Ground Source Heat Pumps cadastre, into a wider Information System for Energy and Environment (SIRENA20). This system feeds and updates the regional energy balance and the regional emission monitoring system. Thousands of building operators, experts, installers and maintainers, managers and authorities use and provide input data into this system, which facilitates dematerialisation and simplification of bureaucracy beyond time and cost savings. Moreover, as a result, the statistical evaluation of these data helps the region in updating its climate goals. The elaboration of scenarios in new Regional Energy and Environmental Plan (PEAR) including the evaluation of the potential energy saving in the residential sector in Lombardy also builds on the inputs of the EPC database, crossed with other information within this regional system intelligence. 8

9 Many municipalities in Lombardy have been able to estimate potential impact of actions on buildings stock in their territories by relying also on EPC data, including public buildings. Access to CENED and use of SIRENA also helped them in drafting the sustainable energy action plans required from signatories of the Covenant of Mayors. Figure 3 shows a typical result based on this data Figure 3: EPCs Open Data: a tool for informing property market in Lombardy 4. Best practice example: Portugal Using Energy Performance Certificate databases: experience of Portugal By Nuno Clímaco ADENE Since 2007 there is a national EPC database system in Portugal. The central EPC database is managed by ADENE. The EPC of almost 10% of the buildings in Portugal are collected in the database. There are monthly or annual targets of EPCs quality assessment numbers to reach, based on: typology (residential/non-residential), type of certificate (new, existing), energy experts covering and other criteria. The EPC is being used to verify the effectiveness of some of the national energy efficiency action plan (NEEAP) measures such as energy efficiency fund. EPC information was used to assist the redesign of the building codes, particularly the new energy performance of the buildings in the building regulations by providing real values of the building elements, technical systems or even adjustments of the scope. Based on about 1.2 million recommendations made by energy experts and stated in EPCs, costs and potential savings on energy efficiency measures could be identified and analysed (see Figure 4). 9

10 Figure 4: Evaluation of impact of energy saving measures Credible information for the real estate market is one of the services made available through the EPC database. Thus the EPC database has become a powerful tool to evaluate buildings performance and to provide information for decision makers but its potential has not yet been depleted. 5. Best practice example: Scotland, UK Targeting domestic energy efficiency, renewable energy and fuel poverty with EPC data By Will Rivers (EST) Using housing data is necessary in Scotland to reach the climate goals and abolish fuel poverty. The old housing stock is inefficient but with easy measures like loft and cavity wall insulation, the efficiency could be raised. The local authorities could benefit from data to plan deliverable area based schemes targeted effectively and develop effective plans and strategies. Approximately 28% of Scottish households have an EPC. EST and the Scottish government have started an EPC modelling project to provide either a real or a modelled EPC for every address in Scotland or make this data easily available for local authorities through an interactive mapping portal. Figure 5 shows a screenshot from this portal. Figure 5: Example of elaboration of data: The average fuel poverty and vulnerability risk of Dandee city 10

11 The British approach to the use of data in the EPC database is that the raw datasets by themselves are of limited value to deliver programmes and the data is needed on 100% of homes to be valuable. By combining datasets and using statistical modelling a powerful dataset can be created. The continual programme of updates and improvement keeps the data real to life and enables strategies and action plans to be based on accurate information. The statistical models can predict characteristics more accurately than homeowners and the data presentation is the key. The GIS portal engages more decision makers: currently it is used by 28 of 32 Scottish Local Authorities. 6. Best practice example: Ireland Using Energy Performance Certificate databases: experience of Ireland By Chris Hughes (SEAI) Extracts from the BER (Building Energy Rating = EPC) register, comprising BER (EPC) Certificates, provisional BER (EPC) Certificates and accompanying advisory reports of the Irish database are open to public inspection on a restricted basis. The BER (EPC) Certificate, Advisory Report and Xml data file are normally made available to: The BER (EPC) assessor who carried out the relevant BER assessment A BER (EPC) assessor undertaking subsequent BER assessment of the relevant building The building owner or an agent acting on behalf of the owner, via a BER (EPC) assessor The BER (EPC) database has supported the Better Energy Homes scheme which provides grants to homeowners for roof and wall insulation, boiler and heating control upgrades and solar panels. The Better Energy Warmer Homes Scheme aims at improvement of the energy efficiency and comfort conditions of homes occupied by vulnerable households in receipt of the National Fuel Allowance Scheme through the installation of draught proofing, attic insulation, lagging jackets, low energy light bulbs and cavity wall insulation. According to the evaluation and research done (EPC database in combination with other databases) energy efficiency has a significant, positive relationship with list price of the buildings. A 50-point improvement (decline) in the Energy Performance Indicator is associated with a 1.5% higher list price. Figure 6 shows typical results based on this database. 11

12 Figure 6: The daily Evaluation Energy Performance of the Buildings of Irish EPC database 7. Best practice example: The Netherlands The learning of the Dutch Database experience of the Netherlands By Kees Jan Hoogelander (RVO) The Dutch EPC database is owned and operated by the government. It is mandatory to register the EPC. The information about the availability of an EPC is public and free. The data is used to verify if the goals are reached, does the policy needs adjusting and if a subsidy should be granted. The database is being used for the programme Energy Agreement for Sustainable Growth, which includes forty organisations, central, regional and local governments and environmental organisations. The purpose of this programme was to achieve a sustainable energy supply system by The database has been used for National Revolving Fund for Energy Efficiency, which provides loans to landlords and housing associations. This programme is based on the improvement of the energy label to A or A+. Another programmes EIA: Energy Investment Allowance, which is also a funding programme (tax deduction), is also related to the information and improvement of the energy label of the EPCs. There are also scientific research projects on labels and house-pricing. The information comes from database of transactions of the Dutch Association of Real Estate Brokers and National Energy Label Database. Figure 7 shows the effect of green energy label on the price of the Dutch buildings. 12

17 AUDITORIUM OF VLEVA (LIAISON AGENCY FLANDERS-EUROPE), KORTENBERGLAAN 71, BRUSSELS. 4 TH OF NOVEMBER 2014 Session 2 - Using Energy Performance Certificate databases turning data into action Europe has impressive ambitions for a nearly zero energy transformation of its housing stock. EPCs are key to realising those ambitions. EPC databases/registers are now in place across most EU countries. These databases, coupled with advancements in big data technology, statistical analysis and GIS mapping, have the power to transform our delivery of energy saving programmes. However, too often theses databases are left to gather dust and are not routinely used by policy makers and delivery bodies. A valuable opportunity is being missed. At this workshop, you will hear about the organisations who are maximising the value of the EPC databases, by placing them at the heart of energy efficiency delivery and policy. Speakers will include: - Ireland Sustainable Energy Authority who have pioneered live, easy access to data from EPCs for a wide range of stakeholders - Energy Saving Trust Scotland presenting their GIS software for the Scottish Government which turns EPC data targeting tools for use by local authorities - ADENE Portugal s EPC administrator who have one of Europe s most powerful EPC registers and who are piloting a programme to use it to monitor on-the-ground retrofit activity - RVO, Netherlands A new project to use data from EPCs with financiers to make the case for large scale investment in energy efficiency programmes We are inviting experts from the following sectors to this event: - EPC database administrators: looking to understand new developments in the use of EPC data - Companies particularly energy suppliers who have the potential to use EPC data at scale - Academics working on energy policy and looking to use big data approaches to understand policy progress and challenges - Policy makers at national and European level who want to understand how they can maximise investment in EPC registers to understand policy impact and progress towards EED targets

22 Session 2 - Using Energy Performance Certificate (EPC) database Why a session on Using EPC databases? Directive 2002/91/EC and 2010/31/EU led to an implementation of Energy Performance Schemes all over EU member states; The EPC has a key role in achieving the goal of the EPBD, which is to support the transition of the real estate sector towards energy efficiency; In addition the EPC includes recommendations for the cost-optimal or cost-effective improvement of the energy performance of a building; Useful, detailed and high amount of data is now stored in central registries preparing the ground to unleash action; Homeowners, real state market, policy makers, investors, etc can now benefit from that information The secret now is How to do it and Learn from best practices. 3

23 Session 2 - Using Energy Performance Certificate (EPC) database What to expect from this session? Possible answers to: How are EPC databases currently being used? What is the potential for using EPC data? Who (companies, local government, policy makers etc) have access to databases? Is the data accessible and useable what is best practice in making information practically useful for policy makers and different market actors? How is the data linked to other sources of information (eg data collected from subsidy schemes) and used by government for market monitoring and track retrofit activity? What are the issues around giving different actors access to the data (especially privacy concerns)? 4

24 Session 2 - Using Energy Performance Certificate (EPC) database Relevant facts known about EPC (based on Concerted Action EPBD book Implementing the EPBD - Featuring Country Reports 2012 EPC are issued by Qualified Experts who undergoes specific Training. In almost Member States training is mandatory plus exams; In most cases EPC are issued after a site visit allowing to collect real data and confirming implemented solutions; EPC are the source for cost-optimal or cost-effective improvements; Nowadays technology allows to easily store large amount of data in EPC Central Databases and share it widely; The effective use of an EPC in advertising and as a supporting tool for financing is very important to increase the demand for energy efficiency buildings on the market. 5

25 Session 2 - Using Energy Performance Certificate (EPC) database But some challenges still exist.. (based on Concerted Action EPBD book Implementing the EPBD - Featuring Country Reports 2012 Confidentiality issues/access to information still prevent to take full advantage of databases; Monitoring of the implementation of recommendations is crucial to keep track of the actual improvements in building performance; Some countries already experienced the EPC as a supporting tool for financing, but its still not a common procedure; EPC in advertising: Consumers reaction and market uptake is still unknown, but member states are making some market researches. There is a need to promote the effective use of the EPC data. Hopefully sessions like this one can raise awareness on the EPC potential. 6

82 VERIFICATION OF ENERGY CERTIFICATES The selection of the ECs to be verified is organized so as to potentially involve all Ecs registered in the database, while at the same time ensuring a more likely control on ECs which have an higher risk of non-compliance in accordance with the following factors: number of certifications made by the energy certifier; proximity to values which separate classes; very high EPh values; class energy efficient. In any EC, at the time of registration into the database, a score is assigned that takes into account the abovementioned identified risk factors In 2012, the analyses led to carry out 153 inspections as follows: 119 Energy Certificates; 27 sale contracts without EC; 7 rental contracts without EC. The regional procedure provides that non-compliance of one or more parameters detected during the inspections do not necessarily lead to a negative outcome of the verification. For the result to be considered negative it is necessary that the value of the penalty function (PF) is higher than 20 NEGATIVE POSITIVE Expert workshop - November 4 th,

109 Home Analytics Scotland Targeting domestic energy efficiency, renewable energy and fuel poverty with EPC data Will Rivers Data Insight Manager

110 Why is housing data necessary in Scotland? Policy drivers Carbon targets Fuel poverty Renewable energy generation Housing stock challenges UK has an old inefficient housing stock Easy measures (loft insulation, cavity wall insulation) nearly done More expensive measures need to be targeted Local authorities would benefit from data to Plan deliverable area based schemes targeted effectively 2 Develop effective plans and strategies

111 Using EPC data to target programmes Full EPC data available for approximately 28% of Scottish households However, used in isolation, this does not provide sufficient data to meet the challenge EPC data can be: Out of date Biased towards particular sectors Contain inaccuracies It is necessary to have data on all households in order to deliver programmes effectively and develop long term strategies for improving the housing stock Combination of statistical modelling capable of producing accurate results 3

112 EST and Scottish Government EPC modelling Objectives: 1. Provide either a real or a modelled EPC for every address in Scotland 2. Make this data easily available for local authorities through an interactive mapping portal By bringing together: EPC data Installations data Customer data Mapping data

113 Home Analytics Scotland v3.0 Home Analytics Scotland EPC modelling list of variables UPRN, address and location Property tenure Main fuel type Property age of construction Boiler efficiency band (A- G) Wall construction Loft insulation Energy Efficiency Rating band (A-G) Estimated RDAP fuel bill ( per annum) HTTC - Exposure to wind driven rain zone 5 Property type Habitable rooms Total floor area (m2) Number of dwellings within building (blocks of flats) Wall insulation Glazing type Environmental Impact Rating band (A-G) Estimated RDSAP Co2 emissions (tco2 per annum) Hard to Treat Cavity wall risk Distance to nearest gas meter Listed Building grade Roof orientation (E, SE, S, SW, W) Distance to nearest biofuels supplier Solar PV potential output Distance to nearest dwelling ECO CSCO eligibility Likelihood of income deprivation High fuel cost, low income indicator Wind speed at 10m above ground level Garden size ECO HHCRO eligibility ECO CSCO Rural eligibility Fuel bill (percentage of median) High fuel cost, low income, vulnerable circumstances indicator

120 EPC modelling: Priorities for 2014/15 Priorities for 2014/15 1. Full integration of non-domestic data and EPCs 2. Targeting District Heating 3. Targeting heat pumps use of BGS data 4. Geo-thermal energy potential 5 Full integration of non-domestic data and EPCs

121 Conclusion Raw datasets by themselves are of limited value to deliver programmes Our premise is that data is needed on 100% of homes to be valuable you can t leave homes out just because they don t have an EPC By combining datasets and using statistical modelling you can create a powerful dataset Continual programme of updates and improvement keeps the data real to life Currently used by 28 of 32 Scottish Local Authorities Enables strategies and action plans to be based on accurate information Statistical models can predict characteristics more accurately than homeowners Data presentation is key - the GIS portal engages more decision makers 13

126 Data Protection Act 1998 & Amendment 2003 Data Protection Act (DPA) was initially enacted to protect personal information that was held on electronic media. Personal information is data that can be directly related to a living individual. In 2003 the scope of the Act was broadened to cover paper-based information and also to expand the information that is covered under the Act. For example an address is now considered to be a personally identifiable piece of information and is therefore covered under the Act. If you have access to personal information you must ensure that it was obtained fairly, is accurate, protected against unauthorised disclosure, used only for the purpose(s) for which it was collected and is held no longer than is necessary for that purpose(s).

127 Access to BER Databases Section 27 of S.I. 243 of 2012 provides the basis for deciding who is permitted access to the BER databases Extracts from the register of BER assessors, comprising the name of each current BER assessor, employer and contact details are open to public inspection Extracts from the BER register, comprising BER Certificates, provisional BER Certificates where applicable, and accompanying Advisory Reports are open to public inspection on a restricted basis The BER Certificate, Advisory Report and Xml data file are normally made available to: 1) The BER assessor who carried out the relevant BER assessment, or his or her then employer 2) A BER assessor undertaking subsequent BER assessment of the relevant building, or his or her employer 3) The building owner or an agent acting on behalf of the owner, via a BER assessor Section 10 of the BER Assessor s Code of Practice details the obligations on BER Assessors in relation to BER data confidentiality and data protection
