Using buildings as energy storage - Monitoring project: Detached house H and detached house F Energy source wind power – Energy source solar power

Monitoring and comparison of performance of thermally activated building components in two similarly built, inhabited detached houses with different energy sources (wind and solar power). The functionality of energy supply through wind power or solar energy will be investigated as well as the verification of the practicability of self-regulating system control due to building temperature behaviour. The results provide an insight into the calculation assumptions, system control and feasibility of the smart grid technology.

Short Description

Status

ongoing

Summary

Starting point / motivation

Over the last years in Austria, more than 100 detached houses with thermally activated building components have been built on greatly differing technological standards. For these buildings, no systematic collection of data or experiences regarding the system control and user acceptance exist neither on the technological standard nor on the basis used for planning and design. The planning of the thermally activated building components for these two buildings was implemented according to recently developed design guidelines.

Contents and goals

An essential part of the monitoring project is comparing the measured data with the projected expenses (for both energy supply systems, split into heating/cooling and hot water supply). In addition to that, the buildings are investigated and compared regarding their functionality and temperature behaviour, a comparison of the proportions and availability of renewable energy and its temporal distribution. Finally, the experiences with self-regulating system control are gathered and analysed.

Methods

The data on both buildings of the system is collected and transmitted electronically via internet. The data will be regularly checked for plausibility and, if needed, necessary control intervention is prompted and recorded by the project engineer. After completing the measuring, an extensive analysis including a user survey is executed.

Expected results

  • Comparison of actual results with targeted ones from the calculation of the project

  • Assessment of the user friendliness of the control system

  • Assessment of the user wellbeing

  • Examination of the practicability of using excess energy from wind power production
