European transformation of the energy system

All newsEnergyScientificUncategorized

Article from REHVA Journal 5, 2021 – Em. prof. dr. ir. J.L.M. (Jan) Hensen and drs. J.J. (Jan Jaap) Blüm, CLIMA 2022 topic coordinators Energy

CLIMA 2022 is an international congress with energy concerning plant engineering as one of the main topics. To become climate neutral by 2050, Europe must transform its energy system (which accounts for 75% of EU greenhouse gas emissions). The recently adopted EU plans/strategies to integrate energy systems (European Green Deal and NextGenerationEU) must pave the way for a more efficient and interconnected energy sector, driven by the double goal of a cleaner planet and a stronger economy.

The EU strategy for energy system integration will provide the framework for the transition to green energy. The current situation is based on separate energy systems (silos) with different vertical value chains that coexist and closely link energy sources to their specific end-users, e.g. petroleum products as fuel for the transport sector. This model cannot achieve climate neutrality cost-effectively by 2050; the changing costs of innovative solutions must be integrated into the way we operate our energy system. New connections between sectors must be created, and technological advances must be exploited.

Energy system integration means planning and managing the system as a whole, based on the interconnectedness of different energy carriers, infrastructures, and sectors of consumption. Such an interconnected and flexible system will be more efficient and will reduce costs for society. It could, for example, be a system where the electricity for electric cars comes from solar panels on roofs, while buildings are heated with waste heat from a nearby factory, and factories are powered by green hydrogen produced from offshore wind energy.

Short-term political goals and challenges
Firstly, a more ‘circular’ energy system, with energy efficiency at its core. The strategy will identify concrete actions to put the ‘energy efficiency first’ principle into practice and use local energy sources more effectively in our buildings or neighbourhoods. There is signifi[1]cant potential in reusing waste heat from industry, data centres or other sources, and energy produced from bio-waste or in wastewater treatment plants. The ‘Renovatieversneller’ (a Renovation-accelerator, a Dutch governmental initiative to subsidise sustain[1]able restoration projects) will be an important part of these reforms.

Secondly, greater direct electrification of end-use sectors. Because the energy sector has the largest share of renewable energy sources, we need to use more and more electricity wherever possible: for example, for heat pumps in buildings, electric vehicles in transport or electric furnaces in certain industries. A network of one million charging points for electric vehicles will be among the most visible results, along with the increase in solar and wind power.

For those sectors where electrification is difficult, the strategy promotes clean fuels, including renewable hydrogen and sustainable biofuels and biogas. The EU Commission will make a new proposal for a clas[1]sification and certification system for renewable and low-carbon fuels.

The EU strategy comprises 38 actions to create a more integrated energy system. These include the revision of existing legislation, financial support, research and application of new technologies and digital tools, directives for the Member States on fiscal measures and phasing out fossil fuel subsidies, reform of the market governance and infrastructure planning, and improved consumer information. An analysis of the existing obstacles in these areas will be used for concrete proposals, for example, the revision of the Trans-European Networks for Energy (TEN-E) regula[1]tion or the revision of the energy taxation directive and the regulatory framework for the gas market.

CLIMA 2022 focuses on the relationship between the above and the installation technology sector. The development of building management systems that use heat, cold and electricity from renewable sources is accelerating, creating a need for flexibility and, therefore, energy storage and energy exchange between buildings. In addition, there is a need for innovative HVAC products and performance opti[1]misation through improved design, operation and maintenance of the various integrated mechanical and electrical subsystems. Typically, this includes reducing and balancing energy needs for heating, cooling and ventilation. While this is not exactly trivial in the case of new buildings, it poses enormous technical, social, economic and political challenges for existing buildings.

It is evident that solutions differ from country to country. Exchanging experiences and learning from each other are the main objectives of CLIMA 2022. This is not limited to the technical aspects but includes economic, cultural, legal and organisational aspects. The overall energy system becomes more dynamic and is influenced by additional actors with non-traditional roles. When houses become small power plants, when large building complexes start to exchange energy, or when smart data companies control energy con[1]sumption, the government, grid operators, energy companies, financial institutions, and our sector must respond.

CLIMA 2022, therefore, welcomes original contri[1]butions that introduce, share, broaden and improve scientific and practical knowledge and experience on the following sub-topics:

• Renewable and smart energy solutions for buildings and sites: energy storage; energy exchange; energy flexibility; renewable energy production;
• Designing innovative HVAC systems for optimised operational performance: high-performance HVAC systems and components; smart technologies; opti[1]mised control; optimised maintenance; data-driven operation; digital twins; reducing and balancing the energy demand in buildings: energy transition; technological breakthroughs in insulation; ventila[1]tion; shading; systemic innovations;
• Legislation, business models and shifting responsi[1]bilities: new legislation; public-private partnerships; market initiatives; new business models; new players in the energy market.

14th REHVA HVAC World Congress has its EYE ON 2030

All newsScientific

Article from REHVA Journal 3, 2021 – by Laure Itard (Delft University of Technology(TUD)), Lada Hensen Centnerová (Eindhoven University of Technology (TU/e)),  Atze Boerstra (TUD & CEO BBA Binnenmilieu)


EYE ON 2030
The 14th REHVA HVAC World Congress CLIMA 2022 (22-25 May 2022, Rotterdam, The Netherlands) challenges advances in technologies and standards for a smart energy transition, digitization, circularity and, most important, people’s well-being and health in buildings.

  • How can we create circular buildings, fully heated, cooled and powered by renewable energy?
  • How can we design human-centered indoor environments while mastering life-cycle costs?
  • Systems and techniques are changing rapidly, and more people must be educated to realize this transition. How can we accelerate the uptake and sharing of knowledge in our sector?

The focus is on buildings, the occupants, and the energy and comfort & indoor climate systems. It also includes integration into infrastructures for energy, health, data and education. 

The challenges relating to energy transition, healthy buildings, digitization, circularity and learning are enormous and we need new perspectives, and integration of perspectives. This REHVA World Congress is yours, let’s build the future together!

Call for abstracts
The call for abstracts, which was open until June 18, has been extended until September 15 2021, to answer the demand of many academics and professionals. Contributions may be scientific and technical papers, interactive sessions (discussion forums, seminars/webinars and courses) and invited sponsored CLIMA workshops. Submit your abstract as soon as possible!


Submit abstract


All accepted papers will be compiled into the Digital Conference Proceedings. Agreements are also being made for additional publications in indexed journals.

Exciting mix
Building on a long and fruitful tradition of REHVA World congresses bringing professionals, policy makers  and researchers together in an enthusiastic and energizing environment, CLIMA 2022 will enable you to discuss the latest insights in science, technology and standardization  and find answers to the questions society and our sector are dealing with. The congress will consist of a mixture of keynote speakers, scientific and technical sessions as well as interactive sessions, student activities, technical tours and sponsored REHVA workshops. Executive  Scientific Committee members Marcel Loomans (TU/e), Martin Tenpierik (TUD), Froukje van Dijken (bba- binnenmilieu) and Lada Hensen Centnerová (TU/e) are working on an exciting mix of COVID-19-proof sessions – both in-person and online, with a lot of attention to interaction in discussion forums, webinars & seminars and courses, for which you can also submit an abstract.

For each of the congress themes, the executive scientific organization is in hands of a tandem representing both academia and HVAC professionals.

Theme 1: Energy
Prof. Jan Hensen (TU/e) & Jan Jaap Blüm (CEO at Alba Concept): ‘CLIMA 2022 considers fossil-free energy use in the built environment of vital importance. Development of building services systems using heat, cold and electricity from renewable resources is accelerating, creating a need for flexibility and therefore for energy storage and inter-building energy exchanges. Following this there is also a need for innovative HVAC products  and for performance optimization via improved design, operation and maintenance of the various integrated mechanical and electrical sub-systems. This typically includes reduction and balancing of the energy demands for heating, cooling and ventilation. While this is not exactly trivial in new buildings, it poses huge technical, social, economic and political challenges for existing buildings. Obviously the solutions will vary across countries. Exchanging experiences and learning from each other are the main objectives of CLIMA 2022. This is not limited to the technical aspects, but also includes economic, cultural, juridical and organizational aspects. The overall energy system is becoming more dynamic and is influenced by additional actors with non-traditional roles.  When homes become small energy plants, or when large building complexes start to exchange energy, or when smart data companies control energy consumption,  then the government, grid operators, energy companies, financial institutions and our sector need to respond.’


CLIMA 2022 therefore welcomes original contributions that introduce, share, broaden and improve scientific and practical knowledge and experiences in these areas:

  • Renewable and smart energy solutions for buildings and sites
  • Design of Innovative HVAC systems for optimized operational performances
  • Reduction and balancing of building energy demand:
  • Legislation, business models and shifting responsibilities

Theme 2: Digitization
Associate Prof. Pieter Pauwels (TU/e) & Jan Kerdèl (Senior consultant Building Automation at  Kerdèl Business Development): ‘CLIMA 2022 considers digital solutions that encourage the energy transition in the built environment as a very important theme. Solutions are expected in the areas of (predictive) digital twinning, data-driven smart buildings, data management, and continuous commissioning.  Nowadays digital solutions must be capable of handling a wide variety of HVAC systems and even be self-learning in detecting trends and process anomalies. Stand-alone (add-on) or embedded solutions are possible, but system architectures must include large scale deployment (wired and wireless solutions, IoT, cloud solutions, blockchain technologies). Monitoring strategies are needed that also bridge the gap between Building Automation and Control Systems (BACS) and Building Information Modeling (BIM), and enable lifetime-cost control using system and building-contextual data. Large-scale monitoring of energy, comfort and life-cycle cost performances at an affordable cost level are needed in support of business cases and policies. Finally, the recent COVID pandemic has triggered research on digital-focused design, monitoring and control of ventilation systems, in relation to overall comfort and health. This includes AI algorithms for fault detection and diagnosis, pattern recognition and anomaly detection. ‘

CLIMA 2022 therefore welcomes original  contributions on digital solutions supporting the building upgrading process and building (energy) management’ .

 Building Management Systems for Energy, Carbon, Comfort and Cost Performance:

    • Design for Automation: From BIM Models to BACS
    • Digitization in HVAC control & Health Monitoring
    • Digitization for integration & Building upgrading


Theme 3: Health & Comfort
Prof. Philomena Bluyssen (TUD) & AnneMarie Eijkelenboom (EGM Architects): ‘The achievement of health and comfort of people in the built environment, whether at home, at work, at school, or enjoying free time, is a complex subject that involves physics, behaviour, physiology, energy conservation, climate change, architecture, engineering and technology. The way people feel, experience and behave in their environment is related to the quality of their environment, described by the thermal, air, lighting and sound qualities, but also to the ability of the buildings and systems to respond to people’s changing needs and preferences and the ability of people to respond to new buildings and systems. As shown by the outbreak of the Covid-19 pandemic, building systems have to provide a resilient environment not only on the long term (as climate change is evolving) but also in the short term (for example during a pandemic).  CLIMA 2022 challenges advances in intelligent interfaces and interaction between building, indoor climate systems and humans and welcomes contributions seeking to new approaches to health & comfort in relation to low-energy buildings and energy-efficient retrofit’:

  • Ventilation to reduce infectious diseases
  • Indoor Environmental Quality for well-being in energy-efficient & retrofitted buildings:
  • Thermal comfort in energy-efficient buildings & retrofitted buildings
  • Resilience and climate change


Theme 4: Circularity
Prof. Tillmann Klein (TUD), Bob Geldermans (TUD) & Olaf Oosting (Managing director at Valstar-Simonis): As a result of a growing population worldwide and the need for comfortable and healthy indoor environments, a massive building challenge lies ahead with the development of new building projects as well as the need to upgrade the existing building stock. To ensure a future-proof, sustainable economy for future generations,  the reduction of the use of primary resources is essential. Circularity aims at closing and connecting material, water and energy flows while eliminating waste and reducing the demand for primary resources. The HVAC sector has a particularly high potential to contribute to circularity. Cycling energy, air and water flows is its core business. Components are frequently subject to upgrades and change. The retention and reuse of valuable materials and components offer business opportunities. However, the associated benefits have not yet translated into a large-scale market breakthrough. The sector needs a clear vision on how to achieve circularity goals, based on innovative strategies and an integrated approach with regard to circular design, product technology, business models, and management. CLIMA 2022 considers circularity as a primary challenge for the coming decade. It is therefore inviting contributions that initiate, share, and improve scientific and practical knowledge and best practice examples in the following areas:’


  • Circular Design
  • Product Technology
  • Business Models
  • Management


 Theme 5: Learning & Education
Prof. Christian Struck (Saxion University) & Prof. Laure Itard (TUD): ‘The European targets around the energy transition in the built environment are huge.  To realize the transition towards an energy-efficient, circular, digitized and healthy built environment, an upscaling of solutions is urgently needed. Dissemination of technical innovations and proven knowledge and approaches is needed. The building services sector is essential for realizing this transition: next to delivering the workforce for designing, placing and maintaining all energy and indoor climate equipment in buildings and neighborhoods, the sector also acts as innovator and is the axis between the construction, energy, IT and health sectors, integrating knowledge from these fields. Rapid changes in energy and HVAC engineering techniques and systems and in contracts and processes make it necessary to accelerate the uptake of knowledge in these areas. This means that continuous professional development of the current workforce and  the education of new employees is necessary. There is a growing need for in-company, sectoral and cross-sectoral learning communities. CLIMA 2022 considers advances in Learning & Education as being essential to the sector and therefore welcomes original  contributions demonstrating novel approaches and good practices in developing learning communities and curricula to attract and educate young professionals as well as train experienced practitioners digitally and on the job’.

  • Learning communities
  • Digital education
  • Development of curricula
  • Business models for Learning & Education

CLIMA 2022 measures the temperature of the global installation sector

All newsOrganisingProgram

Anyone who wants to measure the temperature of the international world of installation should register for CLIMA 2022. The REHVA HVAC World Congress, which takes place once every three years, is coming to Rotterdam Ahoy in May. It is the first time in history that this conference is being held in the Netherlands, and TVVL is organising it. “This is the event where science and practice meet, and current knowledge is exchanged. If you want to know what is going on, what new insights there are and how the installation sector is developing, this is the place to be.”


Atze Boerstra, president of CLIMA 2022, is already audibly enthusiastic when he thinks of the many different people who will participate from all over the world and the broad range of topics that will be discussed. Together with Laure ltard and Lada Hensen Centnerová, he is in charge of the content of this prestigious international congress they are setting up together with TVVL in a short time frame. “You could say that this REHVA congress is the European Championship for the installation world. Here, once every three years, we bring together the best people and all the current topics that our sector has to offer. It is a unique opportunity for the Dutch installation and construction industry to have such close and accessible access to it”, says Boerstra, director of BBA Binnenmilieu and recently connected to TU Delft.

Mix of science and practice
Laure ltard, working at TU Delft, and Lada Hensen Centnerová, working at TU Eindhoven, are both vice presidents of CLIMA 2022 and, in that role, responsible for an important part of the content of the congress, namely the papers and workshops. Besides the not to be underestimated social aspect, the CLIMA congress is primarily a scientific event in the field of heating, cooling, ventilation, and air conditioning. This means that a huge amount of new knowledge and practical cases are brought to light to give a strong boost to the knowledge level in the European installation world.

“The congress attracts scientists from all over the world”, says Laure ltard. “But the nice thing is that, here, they also get to meet people from the field in a fairly accessible way. Installers, designers, consultants, manufacturers, but also students and media will be present in large numbers. It is this whole mix of professionals that makes this an event you definitely want to be at.”


Vice Presidents Laure ltard (TU Delft) and Lada Hensen Centnerová (TU!e) and President Atze Boerstra (BBA Binnenmilieu) of CLIMA 2022.


Knowledge exchange around five topics
“You can bet that there will be a lot of start-ups here; companies and researchers who are working on digitalisation, for example: what benefits can monitoring air quality provide, but also how can we monitor energy use and manage it in real time. Everyone has an opportunity to give or participate in workshops and presentations here to enhance their knowledge”, says Lada Hensen Centnerová. “This congress really sets the agenda in our sector. And that’s what makes it so fantastic “, adds ltard.

“A few important subjects will determine the trends”, Boerstra continues. “Of course, they relate to the energy transition. For example, the ‘green deal’ – which the EU is now prominently bringing to the public – for a great part determines the direction in which the installation world is developing. But the COVID-19 pandemic and the phenomenon health, ventilation and healthy buildings is a topic that will continue to be in the spotlight next year. Digitisation is another topic that will be given extensive attention at this conference.”

The trio indicated that they will make CLIMA 2022 into a broad and very diverse congress, where everyone in the sector will find topics that appeal to them. “For example, in addition to the three topics Atze mentioned, circularity is another important one. It is truly a defining issue for the future, one to which the EU is also firmly committed. In this respect, installation technology still lags behind compared to architecture and construction. And the fifth topic is learning & education, which includes new forms of knowledge dissemination,” says ltard. “The congress will therefore also take place in a hybrid form; in addition to the many live sessions, we will stream some of the presentations, workshops, and lectures via the internet.”

Workshops and papers
During the conference, a variety of presentations and workshops will be held, both in plenary sessions and in many sub-sessions. “It goes without saying that we will provide appealing keynotes. It is too early to announce names at this stage, but the presentations will be related to the five topics mentioned. Our aim is to organise the subjects per overarching topic on fixed days during the congress days between 22 and 25 May,” Boerstra says. “Attendees will be able to pick out the day or days that appeal to them most. At the same time, I think that many people will not limit this unique opportunity to just one day. Who wouldn’t want to spend three consecutive days in a stimulating environment, networking with the top European experts in our field.”

“We strongly encourage all market participants to submit topics for interactive sessions,” says Hensen Centnerová. “Our goal is to offer a very wide range of subjects. These can come in the form of discussion forums, seminars or webinars, as well as courses or workshops. We call on specialists, scientists and, in particular, practitioners to submit their proposals before the summer.

Please check here for more information on dates and rules.

ltard continues: “The same goes for our call for papers. Traditionally, a REHVA congress is accompanied by a comprehensive volume containing a wide range of publications. If you want to submit such a contribution, please send us your abstract before 15 September 2021. If the topic is accepted, you can develop the paper and it will be included in the congress proceedings and website. The contribution might also be published in the REHVA Journal or the TVVL Magazine.”

Striving for diversity
The great diversity of CLIMA 2022 is also reflected in the opportunities for companies to offer sponsored workshops; sessions that visitors can attend both live and online. Organisations and companies can also present themselves with a booth at the congress. “There will be a lot to experience”, says Boerstra. “For example, TVVL’s Swiss sister organisation will be celebrating its 50th anniversary at the congress. And the award ceremony for the REVHA student competition will be held here, too. In addition, the winners of the new Healthy Hornes Design competition, created jointly by REHVA and Velux, will be announced during the venue. Of course, there will also be various get-togethers, the conference dinner on Tuesday, and other social events. All this makes CLIMA 2022 a unique event. Truly a ‘once in a lifetime’ experience; and a first for it to be held in the Netherlands.”

“People should definitely not think that of it as an old boys network,” adds ltard. “One of our main goals is to bring together our students, national and international. That is why Young TVVL (see box) is also developing its own activities at this congress. We badly need this generation to meet the challenges that lie ahead in each of the mentioned areas in the years up to 2030.”

Hensen Centnerová concludes: “Apart from the fact that the content of the congress promises to be extremely varied, we also want CLIMA 2022 to be as diverse as possible. Perhaps it will not be quite as diverse as the visitors of the Eurovision Song Contest, which took place at Ahoy last month, but at CLIMA 2022 we also expect to see a lot of young people and women.”

REHVA Journal – CLIMA 2022 announcement

All newsOrganising

Even in these unusual times, preparations for CLIMA 2022 are up to speed. In REHVA Journal 6, 2020 three members of the Organising Committee were interviewed and gave a short update on the status quo. These three persons are Olaf Oosting (TVVL board representative) , Lada Hensen Cntnerova (congress vice-president) and Atze Boerstra (congress president).


‘We are determined to make a succes out of the CLIMA 2022 congress, no matter what.’


What kind of preparation work have you been involved in over the last couple of months?
‘One of the main issues was the congress location. We have been in close contact with the Rotterdam Ahoy Convention Center (RACC) since autumn 2019. Their new entrance building is more or less ready now and can be visited virtually here: WebVR – Ahoy ( We have not signed the final contract yet, as with the corona pandemic things are far from normal. luckily, they have been flexible with us. They, like us, are determined to make a succes of the CLIMA congress, no matter what.’

Any ideas on how the corona pandemic will impact the 2022 edition of the CLIMA congress?
Atze: ‘Apart from all the impracticalities and uncertainties coused by COVID-19: this pandemic has, of course led to all kinds of new questions about the transmission of airborne infectious diseases that are of utmost importance to our field.
