As a knowledge base, the Historic Building Retrofit Atlas (www.HiBERatlas.com) emerged from the project. In the HiBERatlas more than 55 best practice examples are documented. In addition to the management of Subtask A (Knowledge Base) and Subtask C (Conservation compatible retrofit solutions & strategies), innovative technical and organizational retrofit solutions, which have already been applied in national demonstration projects and tested in practice, have been incorporated and further developed through the Austrian participation.
IEA-DHC Annex TS2: Implementation of Low Temperature District Heating Systems
The potential of alternative heat sources is highest at low system temperatures, but current district heating networks are usually high-temperature systems. The aim of the IEA DHC Annex TS2 is to support the transformation of district heating networks towards lower temperatures (the so-called 4th generation). For this purpose, Annex TS2 forms an international platform that enables an exchange on the topics of technology, system, demonstration and competitiveness.
IEA EBC Annex 75: Cost-effective Building Renovation at District Level Combining Energy Efficiency & Renewables
For the conversion of existing buildings into low(st) energy buildings with low greenhouse gas emissions, it is important to know which strategies are most cost-effective to reduce emissions and primary energy consumption of the buildings. In particular, it is important to find the right balance between energy efficiency measures and renewable energy measures. This question is addressed in this project.
