Fields of Expertise

e7 is a research, consulting and planning office on the topics of energy efficiency, energy economy and energy and climate policy.

With our technical and economic know-how we cover a wide range of topics. We see ourselves as a comprehensive provider of energy technology expertise in all aspects of real estate and neighbourhood development as well as facility optimisation. In addition, we support decision-makers in ministries, institutions and companies in Austria and abroad in the development of energy and climate policy framework conditions.

Energy Efficiency and Operational Optimization

Depending on the initial situation in the building (new buildings, existing buildings, degree of mechanisation, documentation of the building operation) and the organisation, we adapt our consulting and engineering services to suit requirements. Years of experience and our knowledge in handling different tools and methods enable us to identify fast and cost-efficient measures as well as to develop long-term optimization strategies.

Energy Audit and Energy Management

The Energy Efficiency Act (EEffG) makes energy audits mandatory for large companies. The companies can decide whether they want to carry out an external energy audit every four years or introduce an energy management system (EnMS) according to ISO 50001.


New Construction and Renovation Consulting

We accompany your project from the initial idea to ongoing operation and see ourselves as mediators between research and practice as well as between client and planners. We check the client's objectives for technical and economic feasibility, formulate them clearly and verifiably for the further planning process and ensure that they are adhered to during planning, implementation and operation.

Energy Innovations and Demonstration Projects

New paths must be taken to successfully implement the energy system transformation. This also requires new processes, business models, tools and technologies. Demonstration projects in which we test and evaluate innovations play an important role.


Lifecycle Costs and Economic Efficiency

e7 calculates life cycle costs already in the project initiation phase and accompanies the client in every project phase so that he has a sound basis for his investment decisions.



Smart Cities and Energy Concepts

e7 supports property developers, municipalities and cities throughout the entire process in the development of renewable energy supply solutions and the integration of e-mobility, PlusEnergy neighbourhoods and smart city concepts.


Energy Services and Business Models

The legal framework for the implementation of the energy system transformation is constantly changing and allows new approaches and opportunities for companies. e7 has years of experience in developing new business models for innovative energy services and can help companies to position themselves well in the future.


Policy Advice and Energy Economics

On the basis of our many years of experience in the analysis of energy industry issues, we advise politicians and companies on future energy strategies.
