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.

See you at WSED’12 in Wels.

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 reegle.info 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 data.reegle.info 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 data.reegle.info. 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).

[...]

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

An article and interview on the current SESAME-S project developments, named “Smart Energy Metering Gets A Semantic Twist“, appear on a visible US-based webblog on semantic technology – semanticweb.com – The Voice of Semantic Web Business.

A users’ view on Smart Meters

Posted by Tassilo Pellegrini on August 16, 2011 under case study, GUI | Be the First to Comment

Smart meters are pervasive and complex devices.  And although the usability and convenience of smart metering devices have improved significantly over the past few years, configuring and using them appropriately demands a lot of effort from the user. Handling such devices efficiently in terms of learning effort, energy efficiency gains and joy is crucial to the broad acceptance and success of smart metering in individual homes and among lay users.

In volume no. 9 of the PsychNology Journal (9/1, 2011, p. 55 – 72) Kerrigan et al. have presented the results of a user survey that investigates into acceptance barriers of smart metering devices among lay users. According to their research the following aspects are crucial for creating acceptance of smart metering technology among this user group:

  • the familiarity of the terminology to the user; lay consumers are not expected to know symbols (such as “[!]” top signal that the meter is working properly ), codes (such as “t2” for the price rate type) or jargon (such as “instantaneous power”)
  • the adequacy of the information to the users’ needs; for instance, users need to get two values and do a subtraction in order to know the consumption in the current billing period.
  • the availability of a back button, since running through 24 clicks in order to see the last information, and having to go though the full series of clicks in order to see it again if by mistake one presses the button once more is not a usable design.
  • the perceptual visibility of the information on the display; this can be improved by avoiding that the meter is positioned in an inaccessible point on the wall, and by increasing the lightening of the display or using a back lightened display;
  • the reduction of superfluous information, since a small display forces to several steps in order to get a long or complex information. A case in point is the sentence “For information about the contract and notifications of failures please call (a telephone number) ” is divided into 6 chunks, each one requiring a click in order to progress to the next chunk. In case the meters model can still be chosen and is not already installed at the consumers’ households, then models with larger displays should be preferred.

Smart Grids Week

Posted by Peter on June 20, 2011 under conferences & events, Uncategorized | Be the First to Comment

I attended the Smart Grids Week conference in Linz on May 26th and here is a short overview of the most important ideas presented there concerning smart metering. In the first presentation Andrea Kollmann stated that the energy efficiency of the smart meter itself has to be considered during the design of a smart grid. She also presented the outcome of some smart grid projects (SMARAGD, SMADA, Smart New World) that deal with legal issues concerning security and privacy of smart grids.

Harald Schäffler talked about a consumer study he conducted. The main points were that there is hardly any market resonance in Germany because smart grids are not interesting for energy providers. From his point of view the key factors to make such a system successful are transparency, costs, control and the social aspect.

The key points of other presentations and the panel discussion were that security is a very important factor also simplicity, transparency and automation instead of user interaction are necessary in order to gain acceptance among users. Due to the growing number of photovoltaic facilities and e-mobility solutions these should also be considered.

So to conclude, the most important aspects when designing a smart metering /smart grid system are security, ease of use and value-added services. One highlight I would like to mention was the last panel discussion moderated by Michael Kerbler which was especially informative and entertaining.
