GBG Gebäude- und Baumanagement Graz GmbH Facility Management – Energiestabsstelle – Ing. Bernhard Wallner 2 GBG Gebäude- und Baumanagement Graz GmbH Ladies and gentlemen, welcome to Graz! I am very pleased to heartily welcome the delegation from Ukraine. Now, let me give you a short introduction: My name is Karlheinz Fritsch. I am working for the urban administration. The field of action of our company, named GBG, includes the whole management and facility service of the public real estate in our city. We develop properties, we also service 600 hectare urban forests, we build public schools, kindergarten, libraries, official buildings and a lot of other public institutions. I think, you are now interested in our special subject called EMS- energy monitoring system.This system is collecting and checking the whole consumption of water, gas, electricity and district heating in every building where EMS is installed. DI Dr. Karlheinz Fritsch

GBG Gebäude- und Baumanagement Graz GmbH Facility Management – Energiestabsstelle – Ing. Bernhard Wallner 3 GBG Gebäude- und Baumanagement Graz GmbH Energiemonitoringsystem (EMS) Why did we install this system in the public real estate? We all are convinced that the improvement of energy efficience is one oft the most important tasks all over the world. Therefore the main purpose of collecting data is to reduce the consumption of energy. Our target is the reduction of energy-consumption approximately by 15 percent. That is very ambitious, I know. DI Dr. Karlheinz Fritsch

GBG Gebäude- und Baumanagement Graz GmbH Facility Management – Energiestabsstelle – Ing. Bernhard Wallner 4 GBG Gebäude- und Baumanagement Graz GmbH First, we installed the EMS in fifty-three buildings. The financing in the amount of 1 million € was done by the office of environment. The consumption is measured in public schools, the city hall, in libraries and so on; all in all fifty-three buildings. The EMS consists oft he following parts : software consumption counter wiring, installation, cabling service in planning, project monitoring… THE PROCESS Energiemonitoringsystem (EMS) DI Dr. Karlheinz Fritsch

GBG Gebäude- und Baumanagement Graz GmbH Facility Management – Energiestabsstelle – Ing. Bernhard Wallner 6 GBG Gebäude- und Baumanagement Graz GmbH Energiemonitoringsystem (EMS) PERFORMANCE OF THE EMS We currently generate reports of the buildings` energy status and analyze the energy efficience. An alarming system is also installed. For instance: If a pipe burst happens, the system promptly informs. A remote control of the heating system permits to regulate and correct all the with the EMS connected parts centrally. DI Dr. Karlheinz Fritsch

GBG Gebäude- und Baumanagement Graz GmbH Facility Management – Energiestabsstelle – Ing. Bernhard Wallner 7 GBG Gebäude- und Baumanagement Graz GmbH Energiemonitoringsystem (EMS) The reports of EMS We generate characteristic codes of the buildings the data is comparable to others We also generate basics for the technical design There are accountings for the tenants/renters An analysis of the different buildings is possible The control of the central heating system is bidirectional DI Dr. Karlheinz Fritsch

GBG Gebäude- und Baumanagement Graz GmbH Facility Management – Energiestabsstelle – Ing. Bernhard Wallner 8 GBG Gebäude- und Baumanagement Graz GmbH Energiemonitoringsystem (EMS) The alarming system includes warning (when deviation is higher than 7 percent) alarm (when deviation is higher than 10 percent) Information/transfer as (PC) or SMS (iPhone ) DI Dr. Karlheinz Fritsch

GBG Gebäude- und Baumanagement Graz GmbH Facility Management – Energiestabsstelle – Ing. Bernhard Wallner 9 GBG Gebäude- und Baumanagement Graz GmbH Energiemonitoringsystem (EMS) remote control of the heating system Central calendar : it makes it possible to prepare, anticipate and control the whole year including weekends and holidays. Local overmodulation : manual override of the renter, when more energy is needed Central overmodulation : for instance when polling stations are needed; on Sundays a central overmodulation is also possible. DI Dr. Karlheinz Fritsch

GBG Gebäude- und Baumanagement Graz GmbH Facility Management – Energiestabsstelle – Ing. Bernhard Wallner 10 GBG Gebäude- und Baumanagement Graz GmbH Energiemonitoringsystem (EMS) first phase of the project – current status One hundred eighty self-acting counters are delivering data for every quarter of an hour. The EMS includes 8o buildings Control of annual electric power consumption bills is possible The EMS is part of the general energy-report oft he community of Graz DI Dr. Karlheinz Fritsch

GBG Gebäude- und Baumanagement Graz GmbH Facility Management – Energiestabsstelle – Ing. Bernhard Wallner 12 GBG Gebäude- und Baumanagement Graz GmbH We are very proud to realize that EMS makes it possible to save 15% percent of energy per annum- and this means a public saving in the amount of 1,2 million €.
