2 ENHEMS BUILIDINGS PROJECT Research and investment in new science findings Actual consumption in buildings usually shows significant deviations from the declared, because of inadequate energy management. The reason lies in the way of management on the rooms level: non-anticipation of near-future outdoor conditions and human factor Main goal of this project is reduction of energy consumption by developing software for building energy management that will take into account thermal dynamics of buildings, weather forecast and human factor, will be predictive and reactive on expected changes Grant Agreement No: IPA2007/HR/16IPO/ Funding Scheme: Science & Innovation Investment Fund Project start date: April 10, 2013, project duration up to July 31, 2015 The project is coordinated by University of Zagreb Faculty of Electrical Engineering and Computing, the partners are Metorological and Hydrological Service of Croatia, ELMA Kurtalj Ltd and Hrvatski Telekom More information: 2

3 Buildings constant change of conditions Conditions in which building is functioning are changing all the time, due to different reasons: External impacts: Atmosphere conditions (temperature, humidity, solar irradiance, wind) Price and availability of power from energy networks Internal impacts: - User preferences and behavior - Condition of energy network in the building - Availability of equipment How to make building consumption optimal without degradation of user experience? Many available solutions on the market ENHEMS Buildings develops innovative solution for energy management, based on predictive model that takes into account weather forecast, operating in ICT cloud environment. 3

4 ENHEMS Buildings concept 4

5 Short overview Enabled systematic design of energy efficiency measures in buildings by combining them and evaluating their effects through ICT, in dynamic building conditions and real-use scenarios Enabled solar irradiance measurement and forecast support in designing and control of highly weather dependent systems throughout Croatia, with possibility of drastic savings Initial prediction for pilot location is that up to 20 % of energy can be saved, with small investment in sensor technology Savings on pilot location will be tested during the cooling season 2015 Comfort experience of users must remain the same Weather forecast Sensors in the rooms Automatic adjustment of heating/cooling commands Energy savings Software available to users 5

6 Meteorological data Meteorological data are necessary for realization of optimal control strategies (Model Predictive Control). Model Predictive Control uses prediction of meteorological data to fully exploit natural resources that we have at a certain moment of the day in order to minimize energy consumption. Depending on the prediction horizon, it is necessary to know the required weather conditions in the future. In order to maximize efficiency and achieve better optimization results it is necessary to know the weather conditions at least 24 hours in advance, with hourly resolution. Weather forecast communication telecom business opportunity 6

7 Brithcore open building automation platform Opportunity form new businesss development in area of energy efficiency and ICT Management of equipment from different manufacturers and integration with ICT systems - Brightcore, Development of the solution for easy and transparent integration of one or several buildings into advanced control network 7

8 Pilot location FER skycraper, 9th&10th floor rooms, equipped with different sensors (temperature, humidity, pressure, electricity consumption, window opening, etc.) Central management based on ICT solution (implemented in Brightcore) 8 EMF Core team meeting, Darmstadt,, June 2015

13 Next steps Check of the concept during the cooling season (summer 2015) getting comparison between model and actual consumption / savings Possibility for telecom operators for new services and new scope of business: energy management in buildings buildings maintenance based on ICT services opportunity for new business solutions with energy distributors and suppliers engineering of collaborative systems in a city with possibilities of autonomous reactions on minute-hour time scales For any further question please contact project lead: Assoc. Prof. Mario Vasak, Ph.D.E.E. Department of Control and Computer Engineering Faculty of Electrical Engineering and Computing University of Zagreb mario.vasak@fer.hr 13
