In International cooperation and development, SERA’s work focuses on the Sustainable Development Goals of the United Nations. Collaboration with universities generates cutting-edge input for our work.


We support in the implementation of European law. With a holistic view, we are able to identify synergies and make use of them in order to actually achieve the goals of the Energy Union and tap the full potential of positive effects without placing an additional burden on the administration.

We assist public administration in achieving real improvements in terms of energy efficiency and user comfort, CO2 reduction, and reduction of environmental loadings in general. Therefore, creating or improving a sound data basis and checking procedures are always an important part of our work.

  • Salzburg Provincial Government, Department Energy management and consulting
  • City of Vienna, Department Energy planning
  • NECP for Albania and Montenegro (integrated National Energy and Climate Plan according to Governance Regulation)

We assist with strategic decisions in the area of energy and natural resources, for example by tackling the following questions together with companies interested in making truly sustainable decisions, for the own company and beyond:

  • What is technically feasible, but is currently failing economically due to the general conditions?

  • What is legally possible, but fails due to lack of will and misinformation?

  • What is economically successful, but has negative social and ecological impacts locally and/or abroad?

  • Where is there medium-term economic potential due to changing framework conditions?

Together we will find the right balance for your company and the path to a sustainable future.

We certainly get the best out of your team. Even for very well running projects, there is usually room for improvement. Reviews and evaluations by uninvolved third parties support you in continuously improving your performance.

  • Project reviews and project evaluations: e.g. SOLTRAIN (SADC)
  • Evaluations of project proposals: e.g. H2020

Our work focuses on Sustainable Development Goal 11 (SDG11) Sustainable Cities and Communities, and Sustainable Development Goal 7 (SDG7) aiming at ensuring access to affordable, reliable, sustainable and modern energy for all. Both have a key role in achieving other Sustainable Development Goals.

Sustainable Energy and Resources Availability - This is how it can be made a reality: People understand what is at stake and support politics. Policy makers and administrations act transparently on the basis of reliable data. To this end, we offer explanatory videos, apps for data analysis and visualization, and navigation guides.

Short videos (approx. 5 minutes) explain complex issues and contexts in an easily understandable way. The Sustainable Development Goals of the United Nations form the thematic framework of the SERA videos. Central are the topics of economic models, energy, raw materials, climate change and related phenomena.

You can see an example here: The "Integrated National Climate and Energy Plan" briefly explained.


We create explanatory videos tailored to your needs. With regard to graphic realisation and animation, various styles are possible. Please contact us if you would like more information at office@sera.global.

Data analysis and visualization are important for decision-making in project development, for the evaluation of policies and the unerring development of effective new policy instruments. We are specialised in climate, energy and buildings and deliver GDPR compliant solutions.

You can see an example here: "Evaluation and visualization of the purchase price collection of Viennese real estate".


We create tools for data analysis and visualisation tailored to your needs. Please contact us if you would like more information at office@sera.global.

The framework conditions and requirements in the field of climate, energy and raw materials are changing rapidly and the complexity is increasing. SERA guides are short virtual training units (approx. 20 min) that help navigate through complex topics and focus on the essentials. They are created based on our experience from numerous consulting and research projects.

You can see an example here: "Energy Performance Certificate, Governance Regulation and Sustainable Financing". (Coming soon)

With transFORMAT to plus-energy neighbourhood: The transFORMAT Analyser (transFORMAT-A) presents selected information of the spatial planning laws of the Austrian provinces in a comparative way. It supports the identification of possible approaches to increase energy and resource efficiency as well as to reduce environmental impacts, especially with regard to the necessary transformation process at municipal level. transFORMAT-A is available here.

Are we getting closer to Sustainable Energy and Resources Availability? Here we assess the state of play in our areas of work, this time focusing on land use and the decarbonization of Austrian municipalities.

Efficient use of energy
— within reach

Solar energy is converted into usable energy by means of collectors. Collectors need space. Availability of land is limited. The efficiency of solar energy use is therefore also determined by the efficiency of land use. The goal is the multiple use of surfaces, such as the covering of noise barriers and the roofing of car parks in front of shopping centres with photovoltaic modules. Good examples are available.

A current example is the legally required sealing of the Müllnern landfill near Villach in the province of Carinthia, which is achieved by means of a solar electricity generation plant. The Müllnern photovoltaic plant is to be designed in such a way that it simultaneously acts as a roofing and final sealing of the landfill. At 35,000 square metres, the plant will be one of the largest in the province of Carinthia. This project is the first of its kind in Austria; there is already good experience with such projects in Germany.

Sustainable settlement development
— put on track

Sustainable settlement development must be resource-efficient, favour the use of renewable energy sources and ensure a high quality of life even in times of climate change. Although concepts and methods have been the focus of research for many years, and informational materials, planning principles, and assessment tools are available, implementation efforts lag behind.

Based on the available information the Austrian Conference on Spatial Planning (ÖROK - Österreichische Raumordnungskonferenz) develops guidelines that can then be adopted by the provinces in their spatial planning laws. The spatial planning laws specify the legal scope that the municipalities have in drawing up zoning plans, development plans and local development concepts. The legal frameworks of the provinces differ considerably in some cases. In practice, however, the legal scope at the municipal level for optimizing energy and resource efficiency is often not used due to a lack of capacity, and for political reasons.

Dealing with climate change and migration
— put on track

Climate change and migration are also taking place in Austria and require a fundamental rethinking of land use. There are prolonged hot spells with temperatures above 30°C in Vienna, parts of Lower Austria and Burgenland, among other places. At the same time, there is out-migration from certain communities and in-migration to other ones. This makes it necessary to completely rethink planning, building and renovation, and initiatives are needed to support the transformation process at neighbourhod level.

Green spaces, ventilation and climate-friendly cooling concepts are in demand. Initiatives to plant greenery on buildings are a step in the right direction, but it must not stop there. Bold steps are needed to optimise land use in transformational areas with vacant and outdated building stock: It is imperative to take advantage of opportunities to redesign and redevelop neighborhoods by applying plus-energy criteria.

EU LIFE Programme for Research and Innovation, grant agreement no 101077169

easySRI aims to enable a smooth and extendable web platform that offers services for the automated calculation of the SRI according to the Final report on the technical support to the development of a smart readiness indicator for buildings accomplished under the authority of the European Commission DG Energy ENER that will act as a basis for an effective implementation of the SRI and allow further testing at Member State level. easySRI aims to introduce additional parameters that address energy efficiency and financial dimensions in view of making the acquired information more understandable and quantitative for the user of the building. Furthermore, easySRI will support the implementation of a number of ML services (i.e. ML-based core engine and wizard tool for performance and smartness upgrades and SRT interventions), which will assist the evaluation and assessment of the building system’s performance and smartness in more than one normalised metrics as per the SRI framework, and provide customised recommendations for upgrades, considering the cost of investment. Furthermore, novel business strategies will promote adoption and engage stakeholders towards evaluating and upgrading smartness in their facilities, while dedicated workshops and training material will facilitate deployment. Finally, the project aspires the update of current standards as well as the inclusion of its outcomes in new or future standards and will investigate links with other EU initiatives such as EPCs, B-Logs and renovation passports in order to maximize the use of SRI concept in EU policies in the fields of energy and buildings.

Funded by EU LIFE Programme, easySRI project has started in November 2022 and will end in October 2025.

Vienna´s Urban Lake Side stands for one of the largest urban development projects in Europe and also for one of the largest smart city demonstration projects in Austria. Supported by the Climate and Energy Fund, Aspern Smart City Research GmbH (ASCR) as consortium leader and the project partners have created a test area on three building plots - kindergarten/classroom, student dormitory and residential building - in which questions about the future of energy efficiency are answered.

ASCR leads a research team consisting of several organizations developing new services and products in the field of sustainable building energy supply. It is the objective to contribute to the Smart City of the future with secure, reliable, and affordable state of the art technology.

A central component of the flagship project Smart City Demo Aspern was the involvement of residents and users. Only with them can the optimal use of energy and the potential savings in CO2 emissions be further developed.

We have worked together with the users of selected buildings in Seestadt Aspern to better understand consumer habits and users’ requirements and expectations regarding products and services related with energy efficiency and renewable energy use in buildings. Based on our findings, we have provided input for technical research and development as well as input for the development of sustainable energy-related services for the future.

Energy savings can also be achieved through behavioural changes. The more differentiated the users, their motives and options for action are known, the better this potential can be tapped. In the development of the Plus energy building, users will become active prosumers who not only consume electricity but also supply electricity to the grid. By using the building accordingly, they can play a decisive role in balancing energy consumption.

The study examined the influence of user behaviour on the operation of low-energy and plus-energy buildings, differentiated according to social, societal and intercultural aspects as well as gender aspects in particular. This resulted in more tailor-made solutions for product development and communication as well as for the planningprocess.

A broad spectrum of building typologies was investigated (large volume residential buildings, office and administration buildings, school buildings, kindergartens, educational campuses), which have been newly built in the last five years to the passive/plus energy house standard or renovated to the lowest energy standard. The entire process, from the start of planning to the current operation, was taken into account.

From this, findings for planning and construction as well as for product development were derived: During planning and construction, conclusions are drawn on the timely involvement of users in the run-up to the project and on adequate advice and information for operation and use. With regard to input for product development, the focus was on building services equipment and control engineering.

The results of the two year project were prepared for different target groups in order to make the highlights interesting for the respective group easily accessible.
