Urban consolidation Lehen - Subproject 1: Fundamental study for an intelligent e-monitoring

The goal was to refine the energy monitoring for residential buildings as well as to find possibilities to visualise the energy consumption and continuously compare it with the "target consumption" in order to get a signal in time and thereby to be able to communicate it to the users. Different monitoring systems were investigated and the experience was evaluated.

Short Description

This project is a sub project of the flagship project "Urban consolidation Lehen".

Status

completed

Summary

In the following years, several projects are going to be implemented in Salzburg’s city district Lehen with the purpose to fundamentally change and renew that part of town. Some of these projects and demonstrative buildings are supported by the EU within the framework of the Concerto II project “Green Solar Cities”. The Concerto Project has been started in June 2007 and will be running until the end of May 2012. During the course of the project, several other construction projects and topics have been developed which did not exist at the time when the contract of “Green Solar Cities” was signed but have resulted out of the ongoing project

work of “Green Solar Cities”. The "Building of Tomorrow Plus" Program provides the opportunity to further focus on activities already initiated and extend ambitious targets of the quality agreement to additional projects in Lehen.

A focal point of the "Building of Tomorrow Plus" Program “Stadtumbau Lehen” (“urban redevelopment in Lehen”), which is being realized as a direct complement to “Green Solar Cities”, is the development of an intelligent E-Monitoring System. Leading motive is the advancement of Energy Monitoring in residential buildings. The project should help in finding ways to visualize the energy consumption. A direct comparison with the projected consumption should be possible in order to give feedback to the users in time. In doing so, permanent optimization of the operating systems can be improved and opportunities towards a positive impact on the user behavior can be examined.

The new monitoring system primarily is aimed at achieving the following objectives:

  • Administration of consumption data and comparison with the calculated values of the energy certificate of the building.
  • Optimizing the management of technical installations via vernier adjustment and through a prompt error message in case of a major deviation from the calculated value
  • Real savings in energy by timely and clearly arranged feedback to users, in connection with concrete and useful hints and tips. Consequently, the visualization of the system will have to meet particular requirements with regard to user friendliness.

As a first step of the project, several already existing Monitoring Systems in Europe have been compared among themselves. Based on findings of the research project "Developing of an application for central visualisation of the energy and resource demand in a private household 'ZENVIS'" there have been further investigations concerning the current status of various E-Monitoring projects, their practical suitability and future trends. Additionally, emphasis has been laid on regional experience with Energy Accounting and Energy Monitoring in Salzburg. Past experience of other projects has been used, data recorded and analyzed and consequently a basic concept has been developed for applying an E-Monitoring System in the city district Lehen. Involved in the process were three non-profit building promoters, Salzburg AG as energy supplier, a representative of the Department for Energy Business Salzburg, representatives of the installation technology and building service industry with experience in the field of E-Monitoring and other external experts.

Within this interdisciplinary research group different approaches have been discussed, diverse concepts considered and as outcome a guideline and basic concept has been developed to meet the above mentioned requirements.

The new buildings of the "gswb" and “Heimat Österreich“ in Lehen are being used as primary objects for applying the new developed system. In the course of a general information of the residents an attempt is being made to analyze the user behavior and display changes in user behavior. The implementation of the E-Monitoring system is another module of the "Building of Tomorrow Plus" Program “Stadtumbau Lehen”.
