BTTAB - Broad-based testing of energy-efficient demonstration buildings with thermally activated building components

Buildings with thermal building component activation that have not yet been researched in as many federal states and application categories as possible will be monitored, which will include operating data as well as the experiences of those involved. The aim of this study is to take a general look at the various applications of the thermal building component activation technology and to evaluate and compare the pilot projects with the help of suitable evaluation criteria.

Short Description

Starting point / motivation

The expansion of renewable energy generation as well as extensive possibilities for energy storage are central cornerstones of the necessary energy transition. Thermal building component activation can be a key component here, as it can be used multifunctionally as a heating and cooling delivery system and as a storage system for fluctuating renewables. These applications not only offer enormous potential for the integration of renewable energies and waste heat, but they also promise high economic attractiveness and impress with their simplicity in implementation, operation and use.

Contents and goals

In order to accelerate the market introduction of thermal component activation in this still very new application, the service in question is intended to provide information about the performance of the storage and energy flexibility potential on the one hand, and to generate essential findings with regard to user comfort, user satisfaction, economic aspects in construction and operation as well as functionality of the process flows on the other.

A portfolio of about 40 component activation demonstration buildings was generated from the network of the applying consortium, with the owner's consent to participate in a one-year monitoring.

The portfolio is characterized by high diversity, e.g. harmonized regional distribution, different building uses and sizes (residential, office & administration, accommodation, education, health care, manufacturing, warehouse, etc.), different construction methods and activated materials (concrete, brick, wood, clay), different ways of integrating renewable energies as well as different initial situations (new construction, renovation of existing buildings). From this, the project consortium has created a qualified proposal for the required 18 demonstration buildings (two per region), whereby the entire portfolio is available in the final selection process with the client.


Based on the existing equipment of the demonstration buildings with sensor technology, a monitoring concept was already developed in the application, which is also interesting from an economic point of view, and which will be adapted in detail for each demonstration building after the final building determination at the beginning of the project.

During at least one year of monitoring, the project team will, on the one hand, deal intensively with the energy balance and the recording of temperature profiles (at least in 15-minute resolution) and, on the other hand, devote itself to the question of comfort and user comfort (temperature, sound, humidity).

Complementary to the energy and comfort monitoring, a special concept was developed to query and analyze the subjective satisfaction of the building users, which will be applied to the 18 demonstration buildings. Targeted surveys of stakeholders (investors, planners, executors) complete the creation of a comprehensive and well-founded knowledge base.

Expected results

The findings and recommendations will be summarized in a comprehensive publishable study and additionally aggregated in a special form (e.g. as a guide) for potential decision makers.

The project team submitting the application has brought together players who have excellent networks in the industry and already have years of experience in the planning, implementation and scientific monitoring of component-activated buildings as well as field measurements in general.

The consortium is also supported by a total of 10 relevant industry representatives, who have committed via LOI to support work on the content and dissemination of the project results.
