The following Position Papers have been developed by the IEA Solar Heating and Cooling Programme:

Position Paper: Compact Thermal Energy Storage: Material Development for System Integration
IEA SHC Task 42: Position Paper
August 2015 - PDF 0.2MB
By: IEA SHC Task 42
This position paper explains the potential, the present status of development and the market status of compact thermal energy storages. Its aim is to inform policy makers, decision makers and opinion makers about the technologies and to discuss the technological and non-technological barriers and the actions needed to accelerate the development and market uptake of these very important technologies.
Position Paper: Compact Thermal Energy Storage: Material Development for System Integration
Position Paper: Net Zero Energy Solar Buildings
IEA SHC Task 40: Position Paper
June 2015 - PDF 0.35MB
The aim of this Position Paper is to present the current status of the various research and pathways in designing and constructing net-zero energy buildings (NetZEBs). It is written to provide general information on this topic to policy and decision makers who may be in positions to facilitate the market uptake of NetZEB practices. The information therein draws from the work of the 82 National Experts from the 19 member countries that participated in the Task/Annex and have contributed so much knowledge to advancing this field.
Position Paper: Net Zero Energy Solar Buildings
Position Paper: Polymeric Materials for Solar Thermal Applications
IEA SHC Task 39: Position Paper
June 2015 - PDF 0.28MB
This position paper describes the current state of the art for polymeric materials in solar thermal applications, shows the potential of polymers in solar thermal applications, and encourages further R&D activities.

The major advantages of using polymeric materials in solar thermal systems are economical aspects, especially when taking into account the increasing solar thermal market and increasing raw material prices for metals. Although the cost of materials per mass unit might often be put forward as a major advantage of polymers relative to metals in conventional collectors, the entire picture is more complex.

Many successful applications of polymeric materials in solar thermal systems that perform equally well or better in terms of conventional energy savings, reduction of materials, as well as production, transport, installation and/or end-user costs have been demonstrated.

Position Paper: Solar and Heat Pump Systems
IEA SHC Task 44: Position Paper
September 2014 - PDF 0.53MB
By: IEA SHC Task 44
The purpose of this document is to provide an inside view to energy policy makers on why and how solar and heat pump systems should be supported and promoted.

Solar and heat pump systems (S+HP) are a combined technology that represent a market share in the building heating and cooling segment due to their following advantages: high renewable energy share, low electricity demand, low primary energy demand, and low CO2 emission depending on the electricity mix feeding the heat pump.

The market share of S+HP systems could reach 100% for new houses in many countries where the heat pump technology is well-established and solar is mandatory for domestic hot water.

IEA SHC Task 38: Position Paper
October 2011 - PDF 0.67MB
By: Hans-Martin Henning
After ten years of numerous research, development and demonstration activities in the field of Solar air-conditioning, in particular within the IEA Solar Heating & Cooling Programme but also in many other national and European R&D projects, the market penetration of SAC remains small.

Therefore, it is important to take a look at the achievements and the recent position of solar cooling technology. It is also important to understand the future perspective of this technology and formulate the needs related to both R&D and market stimulation in order to exploit the potentials. This is also important in order to understand the potential of solar heating and cooling technologies (SHC) to contribute to the achievement of politically set targets in the reduction of energy consumption. This paper describes the recent position of solar cooling technology and develops an outlook about the potential and needed actions.
