(left) Visualization of the directivity measurement procedure: (a) the red box represents the sound-emitting HVAC component (e.g. heat pump); (b) sound pressure is recorded at a certain distance from the emitting surfaces at 5 locations - a measurement surface is created; (c) beams are created connecting the corners of the emitter to the corners of the measurement surface; (d) parts of the planes spanned by these beams intersect with a sphere; (e) final visualization of the 5 parts of the hemisphere associated with the 5 microphone measurement positions. (middle) 5 microphones are placed around a sound emitting object, one on each side and one from above. The lower part of the image shows the five signals and their corresponding frequency content in waterfall diagrams. (right) A laboratory heat pump (SilentAirHP) in a real environment with AR, with frequency dependent sound propagation.

nZEB - Residential Building D12 – Aspern / Vienna / Austria
The residential building “D12” is a block of 7 buildings with 4-6 storeys each, commercial use on the ground-floor on 900 m². The conditioned gross floor area is about 19,080 m². The buildings’ heating and DHW system is basically based on different heat pump technologies. The overall energy delivering system is designed to support demand response with a multitude of different energy sources. The building blocks are in operation since March 2016.

Test objects with photovoltaics from the south, left: unconditioned, right: conditioned with the COOLSKIN system
Two identical test buildings are available on the campus of Graz University of Technology, which have an almost identical thermal behaviour. The functional model of a PV-powered façade-integrated cooling and heating system developed in the COOLSKIN project was installed in one of the buildings, the second remained unconditioned. The developed system was successfully tested in a 1.5 year monitoring period.

nZEB office building Post am Rochus
The building owner’s goal was to design, build and use a modern, comfortable building. The building development process aimed to have very high standards of sustainability and energy efficiency in achieving, commissioning and operation. Therefore, the construction project was supported by research experts from the Austrian Institute of Technology (AIT). The overall objective of the research project was to shorten the commissioning phase by detailed investigation and optimisation of the control strategies of the building services engineering. Through the application of integral planning, construction/operating companies were brought together with experts. The results were clearly documented and control strategies were hardware tested in advance so that malfunctions could be detected, avoided and eliminated.

Austrian examples for industrial heat pumps, distribution in industrial sectors
A total of 68 examples of industrial heat pumps in Austria were collected. Those systems are considered that are integrated into an industrial or commercial process on the heat source and/or sink side. The examples come from various sectors whose good suitability for heat pumps is already known, such as the food industry (17 examples), energy suppliers (11 examples) and the metal processing industry (11 examples).

Austrian examples for industrial heat pumps: heat sinks
Industrial heat pumps are most often used to heat buildings (33 examples) or to provide district heating (19 examples). Heat supply for processes occurs in 13 examples.

Austrian examples for industrial heat pumps: time of commissioning
Numerous industrial heat pumps were put into operation after 2012. This clearly shows that the spread of industrial heat pumps in Austria is increasing and that more information about these systems is also being published.

Experimental setup for investigating the frosting performance of heat exchangers at low ambient temperatures
Measurement sequence: in the initial phase the thermal mass of the heat exchanger is accommodated to the tempering conditions (A to B1), and then the main frost growth takes place (B1 to B2). Afterwards, the rapid change of the heat exchanger thermal state (at air flow rate curve steepest gradient) takes place (B2), and frost creation continues until the heat exchanger is fully blocked and the temperatures do not change any more (C).

Combination of Methods used by TCP-Activities
A set of methods was developed to categorize the kind of project work that is done in the activities. The figure shows which methods are applied how often in total (node size), and which methods were frequently applied together (edge width) by activities. The color corresponds to the different method cate-gories described in chapter.

Participation of countries in IEA Technology Collaboration Programmes and Related Research Topics
Absolute (upper chart) and relative (lower chart) number of TCP-activities that countries are participating in. The color code shows how the assigned activities are related to the IEA-Topics and how the countries set their priorities with regard to the research topics (based on the IEA RD&D taxonomy).
