Many experts and policy makers may agree that heat pump is one of the most promising technologies for decarbonizing buildings. However, it seems that those engaged in the design and relevant standards of the heat pump systems have not obtained enough information on actual behaviour of the systems in order that we can certainly succeed in reducing energy consumption. For example, do we know how much energy efficiency (EER and COP) of the systems may be reduced under low part load ratio and how low the partial load ratio can be for heat sources? This webinar series is to share such existing technical problems and the way to solve by Annex 88, an international collaborative R&D project.

This webinar series was organized by IEA Technology Collaboration Programme on Energy in Buildings and Communities (IEA EBC TCP) and Annex 88 "Evaluation and Demonstration of Actual Energy efficiency of Heat Pump Systems in Buildings".

About IEA EBC Annex 88
Home page: https://iea-ebc.org/projects/project?AnnexID=88
Overview with its objectives: 
It is a 5-year project, which deals with state-of-the-art (Subtask A), testing methods for heat pumps (Subtask B1), monitoring methods and database (Subtask B2), energy use calculation methods especially for regulations (Subtask C) and design guidelines for practitioners (Subtask D). The state-of-the-art report is to be published in September 2024 and it includes current status and research plan of Annex 88. By using this opportunity, we hope to share the contents of the report.
Duration: 
July 2022 - June 2027
Member countries: 
Australia, Brazil, Canada, China, Germany, Italy, Japan, The Netherlands, Philippines
