Title: Watts the Deal? The peer-to-peer energy trading board game
Moderators: Alexandra Schneiders and Michael Fell, UCL Energy Institute

This session will be an opportunity to hear about, and play, our brand new peer-to-peer energy trading board game “Watts the Deal?”. In the game, players have to meet their electricity demand throughout the week by using power from their solar panel or battery, or trading with other players or the wider grid. Depending on the version of the game, aims include making the most profit or minimizing imports from the grid. It is a great way to start discussions about the point of peer-to-peer trading, and well as issues of fairness in such trading schemes and in the electricity system more broadly. We will give a brief introductory talk about how and why we developed the game, how we have been using it in public/policy engagement and teaching (and hopefully research), and our plans for the future. There will then be an opportunity to play the game and have a broader discussion.

Title: Efficient heat decarbonisation in the built environment
Faidra Filippidou, European Commission, Joint Research Centre (JRC)

The energy performance of buildings is so insufficient that the levels of energy consumption place the building sector among the most significant CO2 emission sources in Europe. The decarbonisation of the building sector is highlighted as a priority to achieve the EU long term energy and climate goals. More than 40% of the building stock was built before 1960 and 90% before 1990. The rate at which new buildings either replace the existing stock, or expand it, is very low (about 1% a year). The vast majority of these renovations do not reach the full potential energy savings that can be achieved. In this workshop, we will assess the combination of insulation measures and efficient heating and cooling supply technologies for the EU building stock. The goal of this informal session is to explore evidence in order to enhance energy policy advice on the optimal combination of cost-efficient energy renovations. Specifically, we will focus on heating and cooling solutions for residential buildings in the EU. Our goal is to understand the guidance needed, on a policy level, regarding the optimal strategy for improved thermal insulation and, heating and cooling supply options at Member State level.


Title: "Building regulations and standards for efficiency first, sufficiency and real nZEB"
Moderators: Lorenzo Pagliano and Andrea Roscetti, Politecnico di Milan

The main discussion should start from:    

  • EN ISO 52000 and its definition of nZEB which starts from energy needs for heating and cooling)(enegy efficiency first)   
  • Delivered energy, where to consider the on site renewables in the assessment boundary?
  • Member states, what’s on the making? why some states are removing energy needs from the definition of nZEB?
  • Cost optimal is based on the US concept of NET over a year, rather than on nearly ZEB. How to correct this?
  • Reference building calculation methodology is an obstacle in the design phase: how to remove it?

Title: "Energy Master Planning between Building regulations and standards"
Matthias Haase (SINTEF Building and Infrastructure, Norway), Ruediger Lohse (Climate Protection and Energy Agency, Germany)

The main discussion should start from:    

  • Step-by-step Energy Master Planning (EMP) for communities. Who are the stakeholders?
  • Natural and imposed constraints. How to define the site specific?
  • Relation to EN ISO 52000 and its definition of nZEB. Energy needs for heating and cooling and….?
  • Single owner vs. multi-owner. What makes the impossible?
  • Base case, baseline and useful scenario development?
  • How does the concept of resilience fit into the Energy Master Planning? What are the next steps?

Title: Reducing the environmental impact of data centres
Moderator: Sophia Flucker, Operational Intelligence Ltd

  • Background - what is the environmental impact? Energy consumption, growth, embodied impacts
  • Drivers for change including impact of policies measures
  • Opportunities for waste heat reuse
  • Barriers to change


Title: “Business models for net-zero renovation on an industrial scale using prefabrication
: Sibyl Steuwer and Jonathan Volt, BPIE

In our research for the German Umweltbundesamt, we identified some barriers and success factors to bring so-called industrial renovation solutions (e.g. “Energiesprong”) into the mass market. Besides process barriers, bringing down the costs is one of the most important barriers to tackle.

We would like to discuss the following topics

  • How to get the costs down: What are experiences and ideas from experts around Europe? What kind of costs are most important? How to bring them down? (Labor vs. Material costs; role of automation on and off-site in bringing down costs, appropriate project size, etc.)
  • What is the role of the state to bring costs down: What are appropriate support instruments and what legal barriers need to be removed? (e.g. tender schemes, loan and grant schemes)

The session will be a joint innovation lab aiming at prioritising the drivers that can bring down the costs.


Title: Energy Demand Science in a De-Carbonized Society
Moderators: Yoshiyuki Shimoda and Alan Meier

Now is the time to assemble our stock of knowledge from many disciplines so as to manage energy demand and greatly reduce carbon emissions.  We will discuss methods to synthetize this stock of knowledge and to create a “Demand Science”.  We will tackle this issue from Japanese, European, and American perspectives in order to highlight how knowledge stock differs across different nations.

Title: Join a new DSM TCP Task on Hard-to-Reach (HTR) Energy Users in the Residential and Commercial sectors
Dr Sea Rotmann, Dr Aimee Ambrose, Dr Katy Janda, Kira Ashby

DSM TCP Task 24 was the first global research collaboration on behaviour change in Demand-Side Management. It ran from 2012-19 and incorporated feedback and input from over 400 behaviour change experts around the world. We are now onto the next phase in our research, with a new DSM TCP Task on HTR energy users in both the residential and commercial sectors. This kick-off meeting will focus on the many, highly varied definitions of what is a hard-to-reach (or -engage or -motivate) energy user in these two sectors, how they have been addressed in research, policy and programmes to date and what successes and insights we can gather from the eceee community about this hugely important (and largely overlooked) user group. Please join us to learn more about how to reach the hard-to-reach!


Title: The social dimension(s) of the energy transition
Faidra Filippidou

The transition towards a cleaner and low-carbon energy system will require complex transformations that will impact our communities and society. The social and political dimensions of the energy transition are the basis for fairness, quality of life, and fundamental social rights. On top of that, they are of crucial importance for the public acceptance of energy policy measures as the energy transition will redefine the role of all parties involved, including citizens.

The social aspects of the energy transition range from acceptance & awareness (e.g. social acceptance of new technologies, consumer behaviour), over energy justice, inclusion, employment, to ownership issues (consumer co-ownership, partnerships, social innovations in energy). In this workshop, we will discuss those social aspects of the energy transition.

  • How can we avoid creating new inequalities when devising new climate measures − so that Europe’s citizens are not divided into winners and losers?
  • What instruments − from social policy, tax, regional policies and other fields − can be developed to support vulnerable citizens, at risk of lagging behind, in the transition to a climate-neutral economy?


Title: Building bridges in research on sufficiency
Moderators: Edouard Toulouse, Anja Bierwirth, Marlyne Sahakian, Lorenzo Pagliano (ENOUGH network).

The main objective of this session is to bring together scholars interested in energy sufficiency, and discuss research priorities and ideas to better support policy making. The session will build on the experience of ENOUGH (International network for sufficiency research & policy), established two years ago with the goal to  increase the visiblility on sufficiency and facilitate exchanges between experts.

After some updates about the network, a brainstorming will follow with the participants to gather and discuss expectations on sufficiency research, opportunities to increase focus and networking, and ways to inform policy making on sufficiency.

The session is opened to academics and experts - especially those who are already members of ENOUGH -, but also to any other interested colleague.


Title: Subsidies for Energy Efficient Appliances: Program Design and Consumer Response (Buettner, T., Madzharova, B. (2019))
Norbert Herzog

This paper provides empirical evidence on the effects of subsidies for appliances with low energy consumption on sales and prices of subsidized products and their non-subsidized substitutes.
It explores a number of subsidy programs implemented by EU member states in recent years. The empirical identification strategy exploits the trading of individual products within the EU common market. Counterfactuals for the sales and prices of a product before, during and after programs are constructed from the contemporaneous observations for exactly the same product in other EU countries, where purchases are not subsidized.
Our findings suggest that replacement programs with subsidies for energy efficient products exert 
strong positive sales effects, which are mainly driven by intertemporal substitution with consumers 
bringing forward purchases from the following months.
Little price effects are found, indicating that subsidies are mostly passed through to the consumers. Our results indicate that repeated programs tend to be less effective in stimulating purchases and may even exert adverse intertemporal substitution effects in the sense that consumers postpone purchases of subsidized products to take advantage of the subsidy. The results do not indicate significant adverse effects on non-subsidized products.


Title: The Paris Agreement 1.5 C Target and the Role of Energy Efficiency: which Policies and Measures are needed to get us there?
Moderator: Paolo Bertoldi 

Description: The recent IPCC Special Report on 1.5 C has highlighted the need to reach carbon neutrality at global level by mid-century in order to meet the Paris Agreement goal of limiting the temperature raise of 1.5 C by the end of the century. GHG emissions must peak and decline as soon as possible to avoid the adoption of massive carbon removal options in the second part of the century. 2030 predicted GHG emissions under current NDCs are not compatible with 1.5 degree pathways. Energy Efficiency, including sufficiency, can reduce global energy consumption in a short time span and at lower cost than other technologies such as renewables. The informal session will discuss the major finding of the IPCC Special Report on 1.5 C and in particular the role of Energy Efficiency in decarbonisation pathways. The focus of the discussion in the informal session will be on the energy efficiency and sufficiency policies and measures needed to reduce energy consumption at the global level in line with the Paris Agreement. The informal session will also present the outline of the recently started IPCC WG III Assessment Report 6 and highlight research gap on the contribution of energy efficiency technologies and policies.

Title: Let’s make networks more energy efficient — Regulatory Policy Options
Moderators: Paul Ryan (EnergyConsult), Anson Wu (Hansheng) and Terence Smith (Mississippi Consulting)

Since 2015, the European Union has required a range of network connected equipment to comply with the “Networked standby” regulation. However, most network equipment used in Local Area Networks (LAN), including those of the wireless variety, would have difficulty complying. The Total Energy Model developed for IEA 4E-EDNA reveals that energy consumed by LANs located on the edge of the internet is higher than that of WANs and DCs. Ways exist to increase the energy efficiency of wired LANs (Ethernet) but could be more widely used. While wireless LANs (Wi-Fi) presently have little opportunity to save energy. To enable networks to be more energy efficient, the relevant standards and industry representative bodies need to be encouraged to include efficiency in the scope. This session offers us an opportunity to explore how best to engage these organizations so that standards may be developed that can subsequently be called upon in mandatory and/or self-regulatory measures. Also, to discuss avenues of engagement with these organizations.

Title: Competitive tenders for energy efficiency
Eva Geilinger

Competitive tenders are a relatively new way to grant subsidies. They are becoming more and more popular. The difference to the traditional “watering can” approach is as follows: Companies offer to improve their energy efficiency in return for a financial contribution. They decide themselves how much contribution they ask for. Every offer competes and only the offers that save the most kWh per contributed Euro receive a subsidy. The idea is to spend financial incentives as cost-effective as possible. Germany and Switzerland are holding competitive tenders for energy efficiency since 6 - 10 years now. There are other examples from across the globe like Portugal, Brazil and USA.

This informal session gives interested persons the opportunity to learn about the experiences from Germany, Switzerland and others. Persons already involved with competitive tenders can discuss recent developments or challenges that they are dealing with. Proposed agenda for the session: 10 minutes introduction each to the tenders in Germany, Switzerland and possibly others, followed by open questions and discussion.


Title:  Professional Appliances

In contrast to domestic appliances and ICT equipment, commercial appliances often lack energy consumption information. The only appliance category with mandatory EU labelling is professional refrigerated storage cabinets. Refrigerated display cabinets and vending machines will follow in 2021. In addition, there are a number of voluntary initiatives like procurement guidelines and subsidy programs across Europe. Nonetheless, there is still a large savings potential that is not yet sufficiently addressed.

This informal session is about exchanging experiences from different initiatives, learning from each other and coordinating. Possible discussion points:

  • New initiatives or resources, new product groups worth addressing
  • Professional kitchen and catering equipment / health care equipment: green public procurement criteria by the EU and other guides for procurers in the Netherlands, Germany, Sweden, etc. à implementation in other countries, coordination?; voluntary testing protocols for energy performance (like HKI CERT in Germany and ENAK in Switzerland) à advance into EN or ISO standards?
  • Welding machines (draft EU ecodesign requirements), hand driers (EU preparatory study) à a chance for new projects?
  • Subsidy programs for BAT professional appliances (commercial refrigerators, professional induction stoves, dishwashers, heat-pump laundry driers, etc.)


Title: “Leveraging experience on Energy Savings Programmes in order to maximize energy savings”

Moderators: Cédric Jeanneret, Energy Transition Expert, Services Industriels de Genève, Switzerland;

Bram van Megen, Research Assistant, Chair for Energy Efficiency, University of Geneva, Switzerland;

Patricia Gorin, Energy Transition Project Manager, Case Study Feedback (CSF) ambassador, Consultant, Switzerland.

Many European energy utilities and other actors have implemented Energy Savings Programmes (ESP) with the objective of saving energy complementary to or under mandate of existing (e.g. national) energy efficiency policies. However, the experience made is typically not shared and the collaborations between European energy actors to implement energy efficiency measures are still at a very early stage. This workshop will serve to share experiences in implementing Energy Savings Programmes and create a community of energy actors that work together to unleash energy savings among their clients.

Main goals of the session

In order to develop skills to increase the ability of energy actors to implement massive energy savings, we will:

  • Initiate an “energy savings cooperation” to promote science-based case study feedback (CSF), case study sharing (CSS) and work on a harmonized evaluation measurement & verification (EM&V) framework;
  • Discuss the opportunity to create a community of practice to reinforce energy efficiency and sufficiency internationally

Title: "Excess:  How Much Is More then Enough?"
Moderators:  Tim Chatterton and Jillian Anable

Much of the discussion around energy sufficiency and energy justice works from the bottom up - working out how much energy is needed or is sufficient for everyday life.  In this session, contributing to work by the Centre for Research into Enenergy Demand Soulutions,  we want to explore the often controversial topic of 'over consumption':

  • How much energy is 'too much' to be using? 
  • Is excess consumption all the same? 
  • Can it be categorised into different types of overuse (e.g. Accidental, Careless, Discretionary, Frivolous, Decadent, Potlatch)? 
  • Is the role of the state simply to facilitate as much energy supply as is demanded to ensure the lights don't go out?
  • Or should policy intervene to reduce demand to prevent harms caused by unequal access to energy supplies or through environmental impacts of energy generation and use? 
  • Where do the boundaries of 'choice' lie with excess consumption - are people as bound into patterns of consumption by social expectation as they are by the efficiency of infrastructure?
  • And how might answers to these questions affect how and where the levers of policy are applied?

Come and join us to explore whether high-end consumption has the potential to be a valid and acceptable target for policies to reduce energy demand furthest and fastest.

Title: Efficiency and fairness: carbon revenues for a just transition
Louise Sunderland

We will not achieve the Paris goals without significant renovation of buildings, but current policies are not delivering. Visible progress on delivering healthier buildings and lower bills, particularly in social housing and for vulnerable households will help to meet the growing call for a more just clean-energy transition. New reforms to the EU Emissions Trading Scheme offer a bold new opportunity to leverage carbon revenues to deliver significant energy efficiency benefits to households and businesses. Carbon prices have already tripled in the past year, and are expected to stay above €20 for the next decade. Member States control most of this revenue, and will now receive as much as €16 Billion per year collectively. Leveraging a large fraction of the new ETS revenues would produce funds sufficient to transform European buildings. It would help Europe to meet the goals of a decarbonised building stock by 2050, efficient electrification, and alleviating energy poverty.

What are we waiting for?

Join RAP, EuroACE/Renovate Europe and the Coalition for Energy Savings to explore how we build on best practices in carbon revenue recycling and make the case both in Brussels and in Member States for this game changing investment.

Title: Solar generation and self-consumption in the residential sector: overcoming the empirical data evidence-gap
Moderator: Eoghan McKenna

Solar PV has an important role in achieving the goal of net-zero emissions. There are, however, some problems that need to be addressed before this role can be realised: grid-balancing challenges, stalled adoption, lack of empirical evidence to support solar policy, and unquantified behavioural effects. To address these problems there is a need for good-quality empirical data on energy generation and consumption in households with solar PV, yet this is not available because metering of distributed generation is not required by regulation. This information session follows a similarly themed session at the previous summer study and aims to bring together people with interest and knowledge on solar self-consumption to discuss how to overcome this empirical data evidence-gap.

Title: Design Workshop: Energy sufficiency policies to optimise and complement energy efficiency in buildings
Moderators: Tanja Kenkmann and Corinna Fischer (Öko-Institut), Anja Bierwirth and Johannes Thema (Wuppertal Institut)

The design workshop seeks to collect, create and discuss existing and new ideas on energy sufficiency policies in the buildings sector. We are seeking for ideas to plug the holes in efficiency policies as well as for sufficiency policies complementing the existing framework. Starting with the options elaborated so far in projects and publications we’d like to invite the participants to be creative in developing regulatory, financial, informational, and other kinds of instruments and programmes to support and foster energy and emission reduction in the buildings sector. Be smart! Be courageous! Be innovative! (All material will be handled confidentially ;-) In the end we will be voting for the most promising, innovative, and easy to implement ideas.


Title: " Can smart meter data be a game-changer for research and innovation?"
Moderators: Simon Elam, Ellen Webborn, Eoghan McKenna. UCL Energy Institute

Smart meters are being rolled out in large volumes across Europe and beyond. The high quality, high resolution energy data generated by smart meters could be hugely valuable for research and innovation. In the UK, we are developing a Smart Energy Research Lab to utilise smart meter data linked to relevant contextual data about households and domestic buildings. In this session we would like to share knowledge, experience, challenges and best practices with others who are using (or will be using) smart meter data (or similar) across the globe. Topics for discussion include:

  • What are the big questions we can answer through using smart meter data?
    • Academic research
    • Other research and innovation
  • What new methods, techniques, analysis, solutions do we need to realise the value in smart meter data? E.g. Machine learning, AI etc.
  • Smart meter data is a start but what’s next? E.g. Smart Homes, Internet of Things etc.
  • Data quality issues
  • Challenges in accessing data

Title: Experimenting with energy sufficiency: a set of hypothesis for explaining reduced energy usage through living lab experimentation

Moderators: Marlyne Sahakian and Grégoire Wallenborn (University of Geneva)

How and in what way do people change their everyday practices, towards ruptures in routines which use energy services? Please join us for an informal session where we will discuss a set of hypotheses on how to explain change, based on the preliminary results of the ENERGISE project. Through ENERGISE, we engaged in changing social practices through « living lab » experimentation and among 300 households in Europe. In 2018, living labs were rolled out in eight countries (Denmark, Hungary, Ireland, Finland, Germany, the Netherlands, Switzerland, and the UK). The households aimed towards absolute and relative reductions in relation to two consumption domains: they were challenged to reduce indoor temperatures to 18 degrees over a 4 week period in the winter, and to reduce their laundry cycles by half during the same period. We have a set of ideas on what were the deterrents and catalysts for change, which we would like to discuss with a broader group. Contact details:, +4179 393 8733.
