"We will have the destiny we deserve" - Albert Einstein

Energy Efficiency and Renewable Energy


The current energy saving policies are motivated by:

  • The fight against climate change,
  • The medium-term decrease of certain natural resources,
  • The expected sharp increase in costs,
  • Geopolitical considerations related to procurement,
  • And the more than ever increasing need of environmental preservation.

The intensive consumption of fossil fuels has led to a scarcity of directly exploitable resources, while their combustion has a very big impact on the environment.

Controlling the demand of energy and diversifying production sources and technical supplies are two main areas of the French energy policy aiming to:


  • Reduce consumption by acting on consumer behaviour, as well as on equipment and systems conception and management.
  • Promote the use of renewable energies (biomass, solar, wind, geothermal, hydro, heat pumps), by improving the profitability of the systems, their technical integration and their appropriation by all stakeholders.


Our position

Alphéeis assists industrials to develop new products, whether they are related to energy demand control or production of renewable energies.

Our actions are also aimed at improving the use of renewable energy in buildings, the adequacy of these solutions to the needs and their appropriation by all stakeholders.

Finally, Alphéeis also assists governments in defining their energy efficiency support and development policy and renewable energy development.

Market and Services


The liberalisation of energy markets has led to a profound change in many economic sectors. Meanwhile, global warming urgently demands new incentive-regulatory measures, and brings many private and public stakeholders, including local authorities, to make environmental protection a major focus of their development strategy.

This new economic and regulatory environment gives all stakeholders an opportunity to revise their position, reevaluate their partnerships, develop new services, and invent new financial mechanisms. It helps them meet the growing demand to take the environment into account and create a favourable economic and social context for the sustainable development of our society.

Our Position

Alphéeis intends to help all stakeholders facing these developments to better understand, define and implement appropriate strategies, to design and launch new offers and build responses to the new energy market requirements.

European Energy Poverty Observatory (EPOV)

The European Energy Poverty Observatory is a 40 month project, starting from December 2016, aimed at engendering transformational change in knowledge about the extent of energy poverty in Europe, and measures to combat it.

Energy poverty can be understood as the inability to secure adequate levels of energy services (such as space heating, cooling, lighting and information technology), and is estimated to affect more than 50 million people in the European Union.

The EPOV project is funded by the European Commission, and is implemented by a consortium of 13 organisations, including universities, advocacy groups, think tanks, and the business sector. The University of Manchester leads the consortium: Dr Harriet Thomson acts as Project Manager, while Professor Stefan Bouzarovski chairs the Steering Committee. 

Among other objectives, EPOV is geared at improving the transparency of information and policy by bringing together the disparate sources of data and knowledge that exist in varying degrees across the whole of the EU. It also provides a user-friendly and open-access resource that promotes public engagement as well as informed decision making by local, national and EU-level decision makers. The Observatory will support the work of interested stakeholders, based on a holistic approach to understanding and addressing energy poverty in the European Union. 

The main EPOV consortium members are:

Smart meters at the service of low-income households

Smart-Up project, submitted by Alphéeis, consortium leader, and its partners (NEA-GB, AISFOR-IT Ecoserveis-ESP, PIM Malta) is part of the 47 projects selected under the H2020 Energy Efficiency program. This project aims to encourage the active use of smart meters and in-house display by vulnerable consumers. 

5,000 vulnerable households will be involved in 5 partner countries.

The project includes actions relating to the training of installers, social workers and other local actors in close contact with vulnerable households.

In addition to the management of the project, Alphéeis will be particularly involved in the assessment of energy savings generated by the set of accompanying actions insecure households.

The first months of work allowed to:

- Develop training for installers or social workers to accompany insecure households for proper use of smart meters (linky in France)

- Train social workers (more than 300 people were trained in 6 countries)

- Develop a monitoring tool consumption, to enable households to monitor their consumption in the days and months to identify the most energy efficient equipment and habits and the most energy consuming behaviors,

- Develop a survey questionnaire to get to know these households and their relation to energy.

- To initiate visits to 5,000 vulnerable households. Visited households respond to the survey and receive advice to take advantage of smart meters and beyond to implement environmentally friendly practices to reduce their energy bills.

The next phase of the study will focus in 2017 on testing support services to a smaller number of households in order to draw lessons on the value of these various forms of support.

Environmental and Sanitary Quality of Buildings


Recent legislative developments and the increasing environmental concerns now require, for all new and existing building projects, to adopt a comprehensive and transversal approach to sustainable development. Achieving the "factor 4" objective lead to the foreshadowing and the construction of positive energy buildings, with very low energy consumption and high environmental quality.

Many steps are implemented nowadays with the aim of limiting the impacts of the development, construction or rehabilitation of buildings on the environment and on the health of the occupants. Furthermore, considering the viability of the project in terms of overall cost is included in all technical choices and management.

Our position

Alphéeis is involved in the design and support of projects in the environmental and sanitary quality of buildings, by helping different stakeholders integrate them into their daily decision-making and operational practices.

We work on actions which, sometimes only concerning actual buildings are structured and opened to a larger scale, allowing the consideration of the global stakes of the project.

Quantitative infrared thermography for thermal conduction coefficient determination

The FaHeBA project was led by Alphéeis, CERTES (University Paris-Est Créteil) and Maisons Paysannes de France (a french association which strives to disseminate and preserve skills and know-how in the restoration of built rural heritage). The aim of tthe project xas to develop a methodology using quantitative infrared thermography for measuring and analysing thermal characteristics of old builings. This methodology will be non-invase to preserve the building.

The purpose of quantitative thermography is to use thermal camera as a temperature measuring device. Associated with modeling tools, it aims to determine physical characteristics of the studied system, such as thermal conduction coefficient of a wall.

The FaHeBA project comes as a follow-up to previous work carried out by Alphéeis on infrared thermography. The objective was to develop non-invasive and non-destructive methods to measure the thermal characteristics of building walls, while gradually approaching conditions compatible with the current constraints of diagnostics and audits.

This project was structured around 4 technical tasks. The first two tasks aimed to understand thermal behavior of heterogeneous façade walls and to develop suitable theoretical models. They were based on a characterization of old buildings exterior walls ; a modelling of theese walles ; a definition of a measurement protocol. Then a fast method to determine thermal conduction coefficient of a wall was developped in accordance with the previously defined measurement protocole. 

Finally, a guide has been written on quantitative infrared thermography (available in French on the Alphéeis’ website).

The project was selected in 2014 as part of a call for research proposals related to energy-efficient building launched by the french Agency for Environment and Energy (ADEME).

Development of a training offer for Picardy Building professionals in the field of energy efficiency

Alphéeis accompanies the Picardy Regional Council and ADEME Picardie in the development of a new range of training courses on energy efficiency intended for building professionals.

The regional climate-air-energy scheme of the Picardy Region, which took effect in 2012, identified the construction sector as the largest contributor to the reduction of GHG emissions by 2020 and 2050 (both in volume and in percentage ). Among the guidelines for the building sector to achieve the greenhouse gas reduction targets, the region wishes to implement a massive plan to retrofit the building and structuring a dynamic and innovative offer rehabilitation and construction including developing local construction skills courses for better energy performance.

Despite the development of a regional agreement for the development of vocational training signed in 2011 and the deployment of PRAXIBAT® system, today we see that the mobilisation of professionals (workers and artisans) to attend training on the energy efficiency is insufficient in order to meet the objectives of energy retrofits in homes.

The services of Alphéeis aim to establish an action plan for the development of a new training offer adapted to the regional context by realising an appraisal of the training actions currently in place in the regional territory, identifying needs (technical and educational) of building sector professionals and analysing innovative training both nationally and internationally.

Behaviour and energy consumption


Household energy consumption practices and, more generally, the role they play in the supply-demand balance are likely to evolve.

Energy and services suppliers need to build new relationships with them and offer innovative solutions in the context of evolving energy markets and new patterns of consumption and production. The attractiveness and capacity to contribute to the ongoing energy transition depend on the implications of the stakeholders.

On their part, governments, civil societies and local stakeholders, including communities and donors need to address the challenge of assisting households during these rapid and potentially destabilizing changes in the social welfare interests.

However, household related measures cannot be effectively implemented without a detailed understanding of their needs and expectations, that keep on evolving with domestic energy decisions and actions. Likewise, the development of a product or service for households requires a detailed understanding of its success and limit during the different stages of development.

This requires a complete understanding of the logical decisions of different households, and how their needs are evolving.

Our Position

Alphéeis assists public and private stakeholders in understanding the practices and emerging needs of all types of households, in order to develop projects for them. The firm provides its expertise for research, action research or operational projects as well as for multi-level offers, services or support development projects, in order to calibrate actions that are in the testing or deployment phase, to assess their ownership and success factors, and finally, provide feedback.

The approach developed by Alphéeis is voluntarily pragmatic and easily applied in order to be efficient

How to encourage, without force, tenants of social housing to adopt more efficient energy consumption behaviours, via the concept of 'nudge'?

How to bring people, without forcing them, to new, more energy-efficient behaviours and to ensure that these changes are sustainable over time? What are the prospects offered in this field by the green 'nudges'? These are the questions that Alphéeis sought to answer in the context of an action research.

The first step of this research showed that outside of the first research conducted in the US and the UK, very little work was conducted on the application of nudges in the energy field. Secondly, Alphéeis developed several possible reflections to identify actions that can be implemented.

These initial results were presented and discussed during a day of reflection, to which social agencies, energy companies and experts in behavioural incentives were invited. Taking advantage of these exchanges, Alphéeis built several nudges implementation scenarios in social housing to boost mastery of energy consumption in everyday behaviour of resident and tenants of all housing projects.

Evaluation of a mobile device to raise the awareness of social housing tenants to save energy

Alphéeis was asked EDF to conduct a qualitative assessment of the Mobile Pedagogical Habitat (HAPI).

Resulting from a partnership between EDF, the AR Hlm PACA and Corsica and the La Varappe Group, the HAPI aims to educate tenants of social housing residents to save energy. This mobile educational container brings in a playful way and at the heart of neighbourhoods tips and tricks to save energy everyday using concrete and numerical examples. A host greets visitors, help them learn through the an EcoQuizz and provides personalized advice, based on their specific demands.

To achieve the qualitative evaluation of the device, Alphéeis has chosen to organize discussion workshops with residents of neighbourhoods that hosted the container to gather their opinions. These workshops will be held on the first 3 places that have hosted the container: Achards and Les Souléiès residences at Draguignan, the Moulins neighbourhood at Nice and the Pins neighbourhood at Vitrolles.

The objective of these workshops is, firstly, to assess the impact of the device on energy consumption practices of the inhabitants (knowledge and newly acquired habits, discussions raised in households or in the residences,...) and, secondly, to identify the success factors and areas for improvement.

The SoEcoMDE project: International study on the factors that are involved in the use and adoption of dynamically MDE solutions by households

The objectives of reducing CO2 emissions and increasing the share of RES in the French energy mix call for the development of new socially acceptable and economically sustainable solutions, to manage peak demand and constraints of intermittent renewable energy. In this context, Alphéeis conducted a research project to better understand the socio-economic factors that come into play in the use and appropriation of the dynamic Energy Demand Management solutions by households, be it the display of consumption, dynamic pricing or remote management of equipment.

The project was based on the analysis of the most significant work conducted on these subjects by different teams of international research, especially those conducted by sociological research teams. It was supported by ADEME as part of the call for projects "optimised integration of renewable energies and control of electricity demand" of February 2012.

The results were presented at debate workshops organized by Alphéeis on the 10 and 11 February 2014 in Paris. These workshops, which brought together 'Smartgrids' projects developers, service and hardware providers as well as French sociologists, allowed to share the feedback from experiments conducted in France. They also help to reflect on the "best" responses to reach Energy Demand Management solutions and dynamic management of consumption that are actually adopted by households and which bring the expected benefits to the community, households, energy suppliers and grid operators.

Smart Grid - Smart City & Éco-quartiers


Communities are directly involved in more than 12% of the national emissions of greenhouse gas (GHGs). Besides the properties they manage, communities can promote the implementation of a sustainable energy policy through their expertise in land development. Energy poverty, urban services management, informing citizens, diversity of activities, local production management, risk prevention, adaptation to climate change (CFEP), reduction of greenhouse gas (carbon footprint).

For optimal energy solutions, focus should be put more on a neighbourhood as a whole rather than on individual buildings. This optimises the installations and networks, hence expanding local consumption and production.


Technological information and communication are the solutions as they have the capacity to collect, process and exchange information among all the different stakeholders.

The development of Eco-District or Smart City projects follows this logic: integrating the requirements of sustainable development and improving the quality of urban services or reducing their costs. Nonetheless, the creation of a sustainable development project raises many questions due to the diversity and multiplicity of the stakeholders.

Our Position

The scale of the district or territory extending beyond individual buildings represents real opportunities to strengthen the integration of energy and environmental issues, as well as the development of services around the concepts of Smart Grid and Smart City.

Alphéeis brings its expertise in these two areas to develop new methodologies and tools as well as to enable local authorities and stakeholders involved in Eco-Districts operations or urban zones planning to develop an approach combining sustainable development and information technologies.

Study of possible developments of the Programmed Operation for the Thermal Improvement of Buildings (OPATB) concept based on feedback

The Ministry of Sustainable Development launched a concerted observation and monitoring program "exemplary buildings" in 2009 through the PUCA. The purpose of this program is to establish a list of references on buildings in different areas (energetic, environmental, economic, social and organizational) and to analyses the reasons of progress or observed shortcomings.

As part of this program, Alphéeis conducted a study on energy renovation of buildings during local operations. This study aims to analyse the feedback from the stakeholders involved in the implementation of local renovation operations of building stock, particularly in OPATB (Programmed Operation for the Thermal Improvement of Buildings), and identify lessons to define the success conditions of local actions to improve energy efficiency.

Alphéeis study also allowed to analyse the experience feedback from developers who benefited from these local operations through the analysis of various building= renovation projects.

Finally, given the sustained development of Territorial Climate Energy Plans (CFEP), it seemed timely to assess how OPATB could contribute to the establishment of CFEP to facilitate and strengthen the recognition of "buildings "in these operations. The Communities of all sizes and territories now need to acquire new knowledge and skills and share best practices. The experience gained under the OPATB and the tools developed could be invaluable throughout the conceptual planning to action assessment phase of the CFEP approach.

If these contributions cannot be direct, they could easily consider to adapt the tools developed under the OPATB to offer generic methodology sheets obtained from the OPATB and the firsts PCET experience that handled the construction industry to share experiments conducted by some communities on the entire original features.
