Acoustic App
(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.

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.

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.

Process scheme for integrated Energy Master Planning that leads to a Resilient Energy System
How can we achieve resilient energy supply for buildings with critical infrastructure, based on renewable sources? Let us start with analysing the critical functions, assess the resilience, efficiency and sustainability of existing systems and add innovative and validated renewable energy sources as well as storage elements. This diagram shows you how to proceed.

Campus of the Johannes-Kepler university in Linz
A bird's eye view shows the potential of the university campus JKU. Many buildings from different construction ages can become much more efficient through thermal and electrical renovation. This also makes it easier to supply them with a local energy system based on renewable and combined heating and cooling, and to maintain critical functions even in difficult situations.

Classification scheme for building stock energy models
The classification scheme establishes a flexible framework for high-level model classification that: (a) builds from existing classification frameworks while accounting for emerging simulation-based, data-driven, and hybrid modeling techniques; (b) recognizes the potential sub-layers of a building stock energy model; and (c) encourages the description of additional model dimensions that are not readily captured by a high-level classification.

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.
