Energy4buildings - Testing for energy efficiency’s own good

An innovative test stand optimizes heating and cooling with electrical and thermal powered heat pumps and chillers.

Forty percent of the energy consumed is consumed in buildings – that is more energy than the energy used in the industry. This poses a huge challenge for building technology professionals: they need to further increase the energy efficiency of buildings.

The University of Applied Sciences Burgenland (FH Burgenland) campus in Pinkafeld now launched an innovative test stand to help tackle the problem. The project “energy4buildings“ allows systems such as chillers or heat pumps to interact via simulation programs.

The measuring of energy flows allows optimizing individual devices by means of ever new simulation scenarios. Also, the interaction of systems such as heat pumps and chillers or the interaction of electricity produced by the building with power that comes from outside the system can be measured and optimized in several test runs.

For increased energy efficiency units that cover both heating and cooling become increasingly important. New simulation cycles are created with a hardware-in-the-loop (HIL) test stand: e.g. the inlet temperature of a heat pump is measured; the value is communicated to the building and facility simulation software. For example, it calculates the model for an office building with floor heating. The calculated back flow temperature is again entered in the heat pump as real temperature value. Then the next hardware-in-the-loop simulation cycle starts. The special interface between hardware and simulation software plays an innovative role here. With the hardware-in-the-loop principle FH Burgenland spearheads the area of building technology laboratory infrastructure.

Both students of the FH Burgenland and companies benefit from the five-year- “energy4buildings”- project that runs since Mai 2013 and that will come to a close in April 2018. The test stand serves educational purposes, laboratory tutorials and can be used as basis for Master’s theses. Companies can use the test stand for product development so as to improve the energy efficiency of products.
