Technical and scientific monitoring on two levels
• Evaluation of the Fraunhofer Institute of Building Physics (IBP)
• Socio-scientific monitoring for selected projects of the Institute of socio-scientific-
research of Berlin (BIS) in the field of „Human and technology“
Aim: Development of Efficiency Houses Plus and renewable energies

• Life in the Efficiency House Plus has felt comfortable
• The families didn`t have to change their behavior
• The rooms felt comfortable to live in
• Ventilation is very powerful, manual regulation is important
• Control of the technology was not problematic
• There have been no negative changes to health or well being

Technical-scientific-results
• More than 90% of the projects reached an economical acceptable Plus of energy
• Typical time of amortization of extra costs is 20-25 years
• Energy demand was measured 10% higher than projected during 1st year of research
• Energy demand was adapted to 1% deviation during the 2nd year of research
• Battery storages provide autarky-degrees of 30-50%
• Measurement & control of technology have high energy demands
