IEA HPT Annex 60: Retrofitting Heat Pump Systems in Large Non-domestic Buildings
The IEA HPT Annex 60 of the International Energy Agency (IEA) aims to identify and reduce market barriers to the use of heat pump systems in the context of retrofitting large non-domestic buildings with complex HVAC systems.
Specifically, the following objectives are pursued:
- To provide evidence of the practical feasibility and satisfactory operation of installed heat pump systems in large non-residential buildings, including findings related to the decisions that led to the selection of HVAC systems;
- Development of easy-to-use, accessible recommendations based on the selected system components for the respective framework conditions, provision of references, and summaries of the relative strengths of each system option.
The national annex project focuses specifically on the following types of non-domestic buildings: industrial buildings, hospitals, shopping centres and educational institutions (kindergartens, schools, universities) as well as museums.
Experiences and knowledge from successfully implemented large reference projects with heat pump solutions for heating and cooling of (partially) refurbished non-domestic buildings will be collected in a structured way, especially in the course of expert interviews and the analysis of information and data from literature and real operation, and evaluated techno-economically with regard to the decision reasons for the selection of system components and their relative advantages and disadvantages.
The findings will be summarised in easy-to-use, accessible, recommendations clearly presented in the form of guidelines, primarily to help decision-makers find solution paths and identify options that serve as a basis for further, more detailed considerations.
The new knowledge will be widely disseminated to the relevant target groups, mainly in the form of articles on websites, in newsletters of industry associations and as presentations at target group-specific events. In addition, it will be integrated into a training programme for planners in order to sustainably anchor the knowledge in further education.
