Price Reduction of Solar Thermal Systems
Technology Position Paper
May 2020 - PDF 0.2MB
By: IEA SHC Task 54: Price Reduction of Solar, Michael Köhl

The number of solar thermal installations has been declining in the past years, while photovoltaic solar energy use has been booming. This trend stands in opposition to the fact that the need for domestic hot water is steadily increasing worldwide. To strengthen the competitiveness and market uptake of solar thermal applications, Task 54 of the International Energy Agency’s Solar Heating and Cooling Technology Collaboration Programme (IEA SHC) investigated the entire solar thermal value chain with respect to technical and non-technical cost reduction potentials and ways to make the technology more attractive to the end-user.

Solar Heat Integrations in Industrial Processes
Technology Position Paper
May 2020 - PDF 1.09MB
By: IEA SHC Task 49: Solar Heat Integrations in Industrial Processes, Christoph Brunner

Solar Heat for Industrial Processes (SHIP) is at the early stages of development but is considered to have enormous potential for solar thermal applications. The industrial sector accounts for approximately 30% of the total energy consumption  in OECD countries. And, the major share of the energy needed in this sector is used for heating and cooling buildings and production processes at temperatures from ambient up to approximately 350°C. This is a temperature range that can be addressed with solar thermal technologies.

Daylighting of Non–Residential Buildings
Technology Position Paper
February 2019 - PDF 0.27MB
By: IEA SHC Task 50: Daylighting of Non–Residential Buildings, Dr.-Ing. Jan de Boer

Daylight plays a key role in providing a good visual, biologically effective and energy efficient lighting of indoor spaces. Generally, daylight is the light source preferred by humans. Daylight is the major source of regenerative energy for reducing lighting energy consumption. Electric lighting accounts for approximately 15% of the total electrical power consumption and 5% of greenhouse gas worldwide. In nonresidential construction, daylighting – based on distinct evaluation procedures and integrated into diverse energy saving ordinances – has meanwhile become an energy-quantifiable and plannable light source that can be directly offset against the energy requirements for electrical lighting.
