Efficient Air Conditioning

Project CETIEB – Cost-Effective Tools for Better Indoor Environments in Retrofitted Energy Efficient Buildings

About 40 percent of the energy used in Germany is consumed in buildings. The energy-related refurbishment of older buildings is therefore part of the political agenda. However, improved insulation of buildings is usually accompanied by a poorer indoor climate.

In the EU project CETIEB, scientists are working on solutions to optimize the overall indoor climate by combining networked sensors with active and passive systems to improve indoor air quality. In this project, Fraunhofer IPM and its industrial partner Infratec GmbH are developing a novel sensor for the simultaneous determination of the CO2 content and volatile organic compounds (VOCs) in indoor spaces.
