LowEx-Concepts for the Heat Supply of Existing Multi-Family Houses
Funding code: 03SBE0001 A/B/C
Funding period: 06/2016 until 02/2022
Project partner: INATECH – Uni Freiburg, Fraunhofer ISE, KIT
Description
- Overarching research project as a scientific link connecting all works carried out in the thematic project LowEx-Bestand
- Ensuring a close exchange of information between the three pillars of the project network: “Analysis”, “Technology” and “Demonstration”
Objectives
- Development and demonstration of LowEx systems with heat pumps for the energetic renovation of multi-family houses
- (Further) development of electric and gas driven heat pumps as well as heat transfer and ventilation systems
- Rise of profitability and acceleration of the market launch
- Significant contribution to CO2 objectives in the building sector
Work plan
AP 1: Analysis of the existing multi-family houses and the renovation processes
Systematization of the building types, players and processes
AP 2: Technology and system development
Innovative LowEx components and systems for energetically renovated multi-family houses, typing of system concepts, optimisation by type of building
AP 3: System evaluation
Detailed simulation and derivation of recommendations
AP 4: Demonstration and Monitoring
Innovative LowEx systems for selected multi-family houses, comprehensive data collection and analysis
AP 5: Economic evaluation
