IEA SHC Task 61/EBC Annex 77: Integrated Solutions for Daylighting and Electric Lighting

Lighting accounts for around 15% of global electricity consumption - intelligent coordination of daylighting and electric lighting solutions together with integral lighting controls enable significant energy savings. At the same time, the solutions must be optimally planned in a user-centered approach based on the visual and non-visual effects of light. The task analysed user requirements as well as existing technologies and design methods and documented exemplary implementations in case studies.

Energy package Kolpinghaus / Eco-Suite Hotel

The Kolping association’s dormitory for pupils and students has been extended. The energy demand of the newly constructed Eco-Suite Hotel is minimized by use of highly efficient components (such as LED lighting). Locally available energy sources (waste water heat and sunlight) are used and an on-site energy system is being created for the use of the heat energy surplus. Guests at Eco-Suite Hotel can experience life in a plus energy building.

IEA EBC Annex 71: Building Energy Performance Assessment Based on In-situ Measurements

The requirements on building envelope and on building technology are steadily increasing. There is a lack of measurement and analysis methods to control the quality of the built implementation and to optimize the building operation. This project developed a methodological basis to enable an in-situ evaluation of the actual energy performance and building operation. For this purpose, it investigated methods to generate data-driven building models favouring the use of already available on-board data.

IEA HPT Annex 54: Heat pump systems with low GWP refrigerants

The aim of the project was to investigate the current situation in the area of refrigerants with a low global warming potential ("low-GWP"). The focus of the national project lies on the current refrigerant application situation and on an outlook until 2030 on the availability of components and systems.

IEA HPP Annex 47: Heat Pumps in District Heating and Cooling Systems

A significant use of alternative heat sources with the help of district heating and cooling networks is a major challenge for a sustainable energy supply. In times of increasing shares of fluctuating producers such as PV and wind energy, the relevance of heat pumps increases. Within the framework of the IEA HPT Annex 47, potentials and barriers for the integration of heat pumps in DHC networks were analyzed.
