V2Heff – Increasing the energy and cost efficiency of Vehicle to Home SolutionsV2Heff – Increasing the energy and cost efficiency of

Project

With the increasing spread of photovoltaics and electromobility, bidirectional charging of electric vehicles is becoming more and more important. Especially in single-family homes, the implementation of vehicle-to-home (V2H) is much simpler and less complicated than vehicle-to-grid or feeding energy back into larger buildings. ...

EnFK-WW-Elektro – Basics for direct electric heating of domestic hot waterEnFK-WW-Elektro – Basics for direct electric heating of

Project

According to the model regulations of the cantons in the energy sector (MuKEn; as of 2018), the hot water in newly built residential buildings may no longer be heated 100 % directly by electricity. During the heating period, the drinking water must be heated or preheated with the heat generator for space heating, otherwise at least 50 % of it must… ...

HydAb – Increase of comfort and efficiency by new concepts for hydraulic balancing of heat distribution in residential buildingsHydAb – Increase of comfort and efficiency by new concepts

Project

The importance of hydraulic balancing of heat distribution systems for energy-efficient building operation and resident comfort has long been recognized. Nevertheless, it can be stated that there is a lack of expertise and still far too often insufficient implementations occur in practice. Companies have also noticed this gap and have developed new… ...

RoRoStrat – Round Robin Storage tank stratification

Project

Thermal stratification is an important parameter in the energy evaluation of storage tanks. The electrical energy consumption in a heat pump system can be up to 40 % lower with a well stratified storage tank than with a poorly stratified thermal energy storage.
In the StorEx project, SPF introduced stratification efficiency as a key performance… ...

DHWStrat – Thermal stratification of domestic hot water storage tanksDHWStrat – Thermal stratification of domestic hot water

Project

Thermal stratification of heat storage has a high impact on the efficiency of thermal energy systems. This correlation was shown in the StorEx project for combined storage tanks, with a new test procedure for stratification efficiency that is based on the second law of thermodynamics. This procedure is now well established, but could so far not be… ...

16 A-Buildings – Power grid stabilisation and influencing users through electrical power limitation for buildings16 A-Buildings – Power grid stabilisation and influencing

Project

Limiting the electrical purchase and feed-in power of buildings to a low level is attractive for grid stability. Because of this limitation, the building's own solar power consumption would be optimised, the PV system output limited, peak demand reduced and, if necessary, an electric energy storage installed. Due to the different interests of the… ...
