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.

Indoor air pollutants in residential housing

This figure illustrates possible indoor air pollutant sources in residential buildings.

Schematic illustration of the active overflow principle

This figure shows an example of how the principle of active overflow can be implemented in a residential unit.

Example illustration of the Indoor Air Quality metric of Subtask 1

An example of Indoor Air Quality / Energy signature for low-energy residential buildings (data represented here are just for display and do not represent actual situation).

Particulate matter emissions during cooking

The figure shows the emitted particulate matter mass as a function of particle size for three different cooking processes.

Austrian examples for industrial heat pumps: heat sources

Different heat sources are used. The most common heat sources are processes that need to be cooled and waste heat streams, that still usable heat. In addition, waste heat from refrigerating machines and compressed air systems as well as flue gas condensation is used.

Experimental setup for freezing in the AIT's climate chamber without tubing

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).
