dc.description.abstractThe IEA Heat Pump Programme (HPP) Annex 40 "Heat Pump Concepts for Nearly Zero Energy Buildings" deals with the application of heat pumps as core component of the HVAC system for Nearly or Net Zero energy buildings (NZEB). Annex 40 has been structured in four tasks which comprise the following activities: Task 1 – State-of-the-art analysis The Task 1 is to give an overview on NZEB on the national level of the participating countries. In more detail, the political framework in terms of NZEB (e.g. building codes, legislation, definitions of NZEB), the state of market introduction, and applied technologies both on the building envelope and the building HVAC system shall be characterised. The compiled technical concepts shall be analysed regarding the heat pump application. Moreover, technologies shall be classified in a technology matrix and evaluated regarding specific advantages of single technologies for dedicated applications such as new buildings, retrofit, office, residential, etc. Technologies shall also be considered regarding different aspects of the definitions, e.g. characteristics regarding load match and grid interaction, the necessity of a grid connection, or the capability to integrate local storage. Task 2 – Assessment of system technology Task 2 is dedicated to identify promising concepts for the further development of system configurations and in-depth analysis of technologies and system configurations suitable for different applications in NZEB. Concepts shall be optimised by simulations regarding design, integration options, and control, but also regarding further aspects like self-consumption of energy, load match, and grid interaction, which shall be considered in Task 4. Evaluation is made based on energy performance and cost. Task 3 – Technology development and field monitoring Task 3 is dedicated to technology developments on the component and system level as well to gather field experiences of system solutions in field monitoring projects. Marketable and prototype technologies could be lab-tested or investigated in field monitoring. Task 3 is accomplished in parallel to Task 2. Task 4 – Integration of NZEB into the energy system Task 4 is also to be accomplished in parallel and deals with the integration of NZEB into the energy system. An NZEB should be designed in a way not to produce additional stress for the grid. In this respect, load match profiles and grid interaction shall be investigated in order to maximize selfconsumption and minimize grid interaction. Thus, local storage options shall be evaluated. On the other hand, the ability of NZEB to react to signals from the grid (“smart grid”), i.e. demand response technology options shall be examined. Heat pumps are also a unique system in this respect due to the option of a transformation of electrical surplus to storable heating or cooling energy, as well in simultaneity, and due to the connection to source and sink systems which may be used as short-term storage like the ground. Control issues play an important role for these investigations, as well. This report gives the results for the field monitoring project (Task 3) for NORWAY. The Norwegian activities in IEA HPP Annex 40 are organized and carried out by SINTEF Building and Infrastructure (http://www.sintef.no/home/building-and-infrastructure), while COWI AS (www.cowi.no) and NTNU (http://www.ntnu.edu) are subcontracting partners. The project is funded by the governmental organization Enova SF (www.enova.no) and the Norwegian Research Centre on Zero Emission Buildings, ZEB (www.zeb.no).
