Energy management for buildings
Management system for the solar-based energy supply of residential buildings

In the “iHEM” research project, an integrated energy supply using solar energy is being developed for residential construction. A specially developed energy management system coordinates the systems for generating solar power and solar heat with electricity and thermal storage systems...

Phase change materials in buildings
Performance of heat storage systems with PCMs

Phase change materials (PCMs) are only used sporadically in construction, although various products and systems have been available on the market for several years now. The PCM Demo II research project therefore intends to test and scientifically evaluate the practicality of PCMs in buildings.

Increasing the flexibility of CHP plants
Use of heat storage systems and power-to-heat plants in district heating generation

CHP plants can be made more flexible by integrating thermal storage systems in district heating networks, as this enables temporal decoupling of the electricity and heat provision so that the electricity generated by CHP plants can be better adapted to the power requirement or residual load.

Lifecycle cost analysis
Software analyses lifecycle costs

In this research project, software for calculating lifecycle costs was developed as a planning and decision aid for architects, specialist planners and energy consultants. The underlying calculation method is suitable for generally analysing the lifecycle costs of buildings or individual components.

Energy self-sufficient living
Single-family homes with renewable electricity and heating supply

In Freiberg, the performance of two single-family homes conceived as energy self-sufficient buildings is being scientifically investigated. The buildings’ very low heating requirements are met by generously sized solar collectors and heat storage tanks, supplemented in each home...
