LowEx-Bestand Analysis

LowEx-Concepts for the Heat Supply of Existing Multi-Family Houses

Funding code: 03SBE0001 A/B/C

Funding period: 06/2016 until 05/2020

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
