First round of SESAME-S trials with real users has been completed in the school in Kirchdorf

Posted by anna on July 6, 2012 under case study, efficiency gains, platforms & interest groups | Be the First to Comment

The motivation of this trial is to study the effects of different strategies for energy saving systems in schools, with regard to their potential impact on attitude and behavior.

The main research questions are as follows:
• How does the availability of energy awareness services affect energy saving behavior and the attitude of responsibility in a school (as compared to no energy awareness)?
• Does energy saving attitude differ when an energy awareness service is available in the public school space via a tablet in the classroom vs. when people have a personal mobile application?
• Does energy saving attitude differ depending on explicit assignment of personal responsibility?
• How are building automation policy settings of varying complexity being accepted by the end users?

So far, the tablet-based interfaces, as well as advanced policy application have been tested.

In September 2012, the studies will also be made for the mobile end user interfaces.

Power Management Service in Kirchdorf

Posted by Peter on December 21, 2011 under efficiency gains, GUI, prototype | Be the First to Comment

In cooperation with eSYS, FH Hagenberg and FTW, the BBS Kirchdorf was provided with several hardware and software services that measure and control the power consumption of computer rooms. In particular, Smart Meters were installed in three computer rooms and on hallways of the school which measure the overall power consumption of the computers and the light installation. Combined with a power management service from eSYS, this creates an opportunity to optimize the power consumption by remotely shutting down or suspending idle computers.

An Android based mobile client was implemented to provide a graphical user interface for the power management service. With this client all functionality provided by the service can easily be used to potentially reduce energy consumption. The software can be installed on any Android powered smart phone and is designed to be used without any prior knowledge about Android – so everyone should be able to use it. The design of the application is shown in the figure below.

Further research will explore how such a power management service can be used efficiently in a school context.

Linked Data on renewable energy & energy efficiency

Posted by Tassilo Pellegrini on October 5, 2011 under efficiency gains, linked data, platforms & interest groups | Be the First to Comment

The search engine has released a SPARQL endpoint to offer linked open data on renewable energy & energy efficiency. A recent blog post states it as follows:

Following the worldwide trend of Open Government Data as well as Linked (Open) Data, REEEP launched in cooperation with our implementation partner “Semantic Web Company” the new reegle data portal today. On you now can find data on stakeholders in the clean energy area as well as (energy) country profiles. This is just the first step, currently we are working on providing all data of reegle’s renewable energy and energy efficiency thesaurus for public re-use and we are plannign to continuously open up and provide more and more clean energy data on The idea of providing raw data (first mentioned by Sir Tim Berners Lee in the course of the W3C LinkedData movement) for free and unrestricted re-use perfectly fits into reegle’s idea and objectives to act as a single point of access for worldwide clean energy data (renewable energy as well as energy efficiency).

[...] follows W3C standards and recommendations for Linked Open Data as well as Open Government Data, and is implemented under the the Open Government Data License for public sector information licence.

For developers we have created a comprehensive developer guide as well as a SPARQL endpoint as the central API to the data.

As the field of Linked Open Data / Open Government Data (Linked Government Data) is very innovative we would like to ask you for your feedback on – please let us know what is useful for you and what could be useful in the future as well as if you have any problems with the system and / or any suggestions for optimisation!
Many thanks in advance!

We do hope that initiates a lot of new (data) mash ups as well as innovative apps using and also people that re-use the provided data for their daily work in the clean energy business!

FORSA investigates into success factors of smart metering among lay users

Posted by Tassilo Pellegrini on May 16, 2011 under efficiency gains, platforms & interest groups, user profiling | Be the First to Comment

In May 2010 Forsa, the German Society on Socio-economic Research and Statistical Analysis, published a (German) report on the success factors of smart metering for the acceptance among lay users in Germany. According to their research they come to the following conclusion (p. 42):

  • Users need to be informed broadly about the concrete functionalities and purposes of smart metering devices, especially with respect to ecological aspects.
  • Users need transparent and clear definitions of privacy policies, especially with respect to data handling and customer profiling
  • Users need concrete and relevant applications for their daily purposes
  • User will just accept “intelligent” devices at maximum at marginal monthly costs and just with sufficiently low installation fees
  • A higher diversification of energy prices is needed to give the users incentives for changing their behaviour towards peak-insensitive usage hours.

User profiling and saving potentials

Posted by Tassilo Pellegrini on April 20, 2010 under case study, efficiency gains, user profiling | Be the First to Comment

To gain an insight into behavioral patterns four in-depth interviews were conducted with two men and two women living in individual households. The sample was not meant to be in any way representative for a certain kind of cohort, social class or target group but was intended to identify occupancy patterns, device types and their corresponding usage. Therefore, two time frames have been analyzed. The interviewees were asked to describe in detail their appliance usage during morning time from getting up to leaving for work – a time frame which is in so far crucial as morning hours generate peak loads at the energy providers’ side. Additionally, participants were asked to describe a typical week in their lives which was necessary to capture occupancy and sleeping patterns during workdays and weekends.

From this information we modeled a normalized seven day period in a single resident household representing the devices in use, occupancy and sleeping patterns. The average energy consumption per device-type was calculated and differentiated by active and passive use. By applying tariff schemes from the Austrian Energy Exchange  we also calculated the average energy costs for a single household per day and per week. These calculations were crucial as simple scenarios showed that a change in behavior might lead to a reduction of energy consumption but not necessarily to a cost reduction and vice versa if the prices of the energy market would be used by the end customer. These effects have to be observed closely as cost-efficiency and energy-efficiency do not necessarily correlate positively.

The empirical modeling of usage patterns performed within this diary experiment lead to the conclusion that policy based energy control could affect energy savings of up to 24% by simply applying automated turn-off rules to stand-by devices and ad-hoc devices alone when streamlined with the behavioral patterns of the user.

We will continue with this empirical work and search for more granular and non-bivious saving potentails in the following months.
