The aim of this project is to support the further development of policy measures in the field of energy efficiency and climate protection in the field of buildings. For this purpose, framework contractors are to be bound to carry out services of data collection, research, evaluation, conception, consulting and assessment in the above-mentioned subject area. The framework contract partners are to support the ministerial work of the BMWSB in the above-mentioned subject area with short-term written elaborations (e.g. expert opinions, studies, concepts, reports, notes, templates, dossiers, statements, sample calculations, etc.) on examination or research issues.

The following service areas will be allocated as lots:

Lot 1 - Energy-saving and subsidy instruments at national level

Lot 2 - Energy efficiency and climate change mitigation at European level

Lot 3 - Embodied energy and life cycle considerations

Lot 4 - Climate-neutral building stock, building databases and CO2 scenarios

Lot 5 - Municipal heat planning and energy supply, neighbourhood solutions

Lot 6 - Smart Building, Building Automation and Low-Tech Approaches

This lot deals with issues relating to current and future energy-saving regulations as well as funding instruments for the building sector, such as: the Building Energy Act, the Heating Cost Ordinance, the CO2 Cost Allocation Act, the Energy Supply Security Measures Ordinance as well as the Federal Funding for Efficient Buildings and the Climate-Friendly New Construction Funding Programme.

This requires accompanying scientific advice for the further development of the instruments and, in particular, for the further development of the associated technical regulations. Incentives must also be further developed in a targeted manner, especially with a view to removing barriers and improving public acceptance.

This lot deals with issues related to European directives and policy instruments related to the building sector, in particular the European Energy Performance of Buildings Directive (EPBD). With the EPBD, Germany is faced with further requirements that must be taken into account in national legislation. In the course of this, the updating of energy-saving requirements and regulations at the European level will have to be followed and further developed by Germany with great attention in the future.

This requires accompanying scientific advice for the further development of national policy instruments (especially in connection with legal regulations) and, in particular, for the further development of the associated European technical regulations. Likewise, the representation of the public law interests of energy-efficient and climate-friendly construction must be perceived at the European level.

Other topics that will also influence the energy-saving requirements in the building sector in the future are "grey energy" and life cycle assessments. This requires practical life cycle assessments, which should be available for future climate protection instruments. To this end, a framework under public law must be created, but funding incentives must also be further developed in a targeted manner, especially with a view to removing barriers and improving public acceptance.

In order to be able to achieve the climate-neutral building stock by 2045, the main focus must be on the existing buildings. The aim is to achieve structured monitoring, with the difficulty that the data situation and knowledge on the energy quality of the building stock (especially in the case of non-residential buildings) is extremely low. This includes scientific advice in connection with databases (e.g. with regard to the collection of data, the development of a building database), existing information on the building stock as well as the conception, implementation and updating of CO2 scenarios for the building sector as well as recommendations for further climate protection measures or for changes to the KSG (e.g. Offsetting of emissions between the KSG sectors).

Energy supply and cross-building energy supply concepts are playing an increasingly important role with regard to energy efficiency and decarbonisation of the building stock. In connection with the new instruments, e.g. scientific advice is needed on municipal heat planning (Heat Planning Act), the planned district heating summit as well as a new solar roof strategy and other instruments for the decarbonisation of the energy supply. Questions about neighbourhood solutions are also to be dealt with in this lot.

Digital solutions from the field of smart building and building automation are playing an increasingly important role when it comes to reconciling the real energy consumption of buildings with the calculated energy demand ("performance gap"). For this reason, European directives contain requirements in this regard (e.g. Smart Readiness Indicator, building automation in non-residential buildings), which must be implemented at national level. In this lot, a consultation is to take place, both on questions of the implementation of European requirements and on the general use of digital solutions in the building sector.

In certain areas of application (e.g. depending on the type of building user), on the other hand, it may be more practicable to dispense with excessive use of technology in the sense of low-tech solutions and to address the performance gap via passive solutions. A consultation is also to take place in this regard.
